4 Steps to Correctly Use Tool and Cutter Grinder

Step 1 – Prime the Machine

It is always a good idea to turn the tool and cutter grinder on to warm it up. A cold grinder will create rough cuts while a warm or hot grinder disc will produce the best result. Allow the tool grinding machine to run for several minutes before taking tool to the grinding disc.

 

Step 2 – Safety Precautions

Just looking at the tool grinding machine suggests a medieval torture device. There is a lot of moving parts, guides and rails to worry about as well as the grinding disc itself. Always wear heavy work gloves when using the machine. You also need to wear safety goggles. The grinding disc is typically abrasive and made with diamonds. When grinder begins to sharpen the tool it can cause small fragments of the tool, the disc or sparks to fly toward your face. Getting any of these superheated fragments in your eye can be very dangerous.

 

Step 3 – Examine the Tool

Not all tools are made the same and it is important to examine the tool you are about to use the tool grinding machine on. You are looking for the angle of the tool, including which way the blade is curved, how the edges are cut and the contact points. This is incredibly important because to properly use the tool and cutter grinder you need to know what direction the tool needs to go. If you fail to do this, you can severely damage the tool you are trying to bring back to life.

 

Step 4 – Using the Tool Grinding Machine

Double check all of your safety areas and examine your clearance. The kind of tool you are using will determine what the settings need to be. For this information you should always consult the instruction manual that came with the machine you have access to. Not every tool grinding machine is the same when it comes to this. Turn the machine on and keep a safe distance from the grinding disc. Remember the curvature of the tool you are sharpening and place it against the grinding disc at the appropriate angle. A knife, for example, would be approximately 45 degrees. Use short movements and firm pressure until you are satisfied it is sharp.

Before Buying A Surface Grinder, Something You Need to Understand

The surface grinder you need will depend largely on the material that needs grinding. For instance, if any metal surface needs grinding, the grinding wheel should be made of a highly abrasive material, and it should have numerous cutting niches embedded in it. On the other hand, for grinding a wooden surface, what you need is a lesser abrasive wheel.

 

The Types of Surface Grinder

 

There are two basic types of surface grinders, and they are:

 

  • The Planer-type
  • The Rotary-type

 

In the Planer-type, the grinding wheel remains stationary, while the worktable moves in a back-and-forth motion. This movement is controlled either manually or through some hydraulic drive system. These grinders are selected when overall grinding is required once the machine component has left the foundry.

 

In the Rotary type, the grinding wheel rotates, as does the circular worktable. These rotary surface grinders are selected when the precision machine parts require grinding, before being fitted into its housing. In both the surface grinder types, the safety hazards are well taken care of, and because of this, accidents rarely happen.

 

Things to do After a Surface Grinding Job Is Over

 

After a surface grinding job is over, the entire work station should be cleared of debris. If the work was done on a wooden material, the saw dust may be supplied to those who make composite boards, while the shavings from the metal surface can be sent to steel mills for melting.

 

However, what matters most is the safe clean-up of the work area, as otherwise, someone might get injured from carelessly thrown bits of metal shavings. Also, the surface grinder needs attention after each operation. It should be checked for any flying debris that blocks its air vents or any damage caused to the moving parts.

 

TONG YI Machinery Inc. is the outstanding rotary surface grinder manufacturer in Taiwan. If you need more information about kinds of surface grinding machines, welcome to visit their website and feel free to send inquiry or contact with them.

Properties and Features of High Performance End Mills

Companies in the carbide cutting tool industry are under pressure to provide precision tools according to the specifications laid out. Getting a carbide cutting tool is not enough, quality and precision play a crucial role.

 

End-mills are the primary precision tool used by vertical mills. This is a kind of milling cutter which is usually used as a cutting tool in industrial milling applications. It is like a drill bit but varies in terms of geometry, application and manufacture. A drill bit can only cut in the axial direction while a milling bit can cut in all directions, though very few cannot cut axially. Solid Carbide End Mills can be found in a variety of industries, including medical, aerospace, power generation, mold & die and general machining. The quality and style also vary. The most common ones are the 2-flute, 4-flute, 6-flute end mils. You can buy them individually in sets or individually.

 

It is an industrial must that high performance carbide mills be designed with accuracy. Your carbide cutting tool will continue to perform consistently throughout, lasting longer, which helps to keep your quality production line of products on schedule. The success of projects depends on the consistency and reliability of the machines being used. Long tool life increases machine up-time, which provides greater production capacity without investment in additional equipment. The 6 flute carbide-mill is for Radial relief with a thicker carbide core that provides higher strength. This is an excellent choice for nickel/high temp alloys, titanium, carbon steels and stainless steel.

 

End mills provide significant savings for industries in several ways. Almost two to three times faster cutting speed as compared to conventional tools. The quality of the work piece will speak for itself. They also offer excellent dimension control. The result is consistent finishes resulting in minimized scrap rates. Two important properties that have to be considered to determine the efficiency of cutting tools include abrasion resistance and toughness.

 

High performance end mills have been specially engineered for the roughing and finishing of steels and exotic materials. They are made from the highest quality fine grain carbide available, these end mills work where others fail. They have been engineered with a variable pitch design for increasing depths of cut and increased feed rates with reduced chatter.

 

It is increasingly common for traditional solid carbide mills to be replaced by more cost-effective inserted cutting tools. While purchasing an end mill, make sure you check the material, level of hardness, heat treatment, quality and finish.

 

Earth-Chain Enterprise Co., Ltd. is a professional manufacturer of magnetic tools. They also provide end mills and drill grinders for clients.

Transform Grinding into a CNC-Based Technology

In the ever-progressing world of manufacturing nothing stays the same. If you are not improving continuously you cannot stay in the game for long. This is true in all progressive mold shops that have embraced the latest in CNC technology and automation into almost all aspects of production. The exception being that row of grinders that could have time-warped from the middle of the last century.

 

Automation in other areas is shining a greater light on the lack of automation in grinding. Every attempt has been made to move as much out of the grinding department as possible. With great strides being made in wire EDM, high-speed machining, and hard turning and milling, the grinding department is being bankrupted, in many cases. Still there is a need for grinding in mold shops. Every shop has a bank of grinders. There will be a row of manual grinders of the usual types and a cluster of automatics. The technology in these machines remains unchanged in its basic function and capability.

 

The purpose of this article is to set forth some steps that can be taken to change the grinding department into a CNC department, which are based on successes seen in a range of mold shops from small to large—but all having a need for precision grinding of mold components.

 

Automatic Surface Grinder Benefits

  • Operator can keep two machines running unattended.
  • Skill level is lower so most CNC operators can do these tasks.
  • Accuracy is provided by machine.
  • Wheel management for faster, simpler set-ups.
  • Develop repeatable processes that are machine-based not operator-based.
  • Core requirements for job are controlled—including wheel offset, auto-dress, simple dimensional inputs into conversations graphical screens and grind.
  • Critical dimensions can be checked on the grinder automatically.

 

Six Steps to Grinding Transformation

The steps a mold shop can take to transform grinding into a CNC-based technology are:

  1. Strategically build around the correct machines.
  2. Must have a committed attitude from management.
  3. Must have a positive attitude for grinder hand to increase productivity through CNC technology.
  4. Plan to cross-train CNC operators to operate CNC surface grinders.
  5. Develop high competency at core grinding tasks like surface, slot and step grinding.
  6. Think outside the box.

 

These simple tasks can be completed through the assistance of a high-precision CNC surface grinder faster and easier than through conventional manual grinding.

How Does a Surface Grinder Work?

Basics

A surface grinder is a device that is used to accurately and intricately remove unneeded layers from a surface in an effort to smooth the target layer. The reason that a surface grinder is used is that it provides a great level of accuracy and detail that is sometimes difficult to achieve by hand. The use of a surface grinder is concentrated in heavy industry, especially in the automotive industry. Surface grinders are used on various types of metal and woods. The surface being worked on is directly related to the blade being used as they are specialized for different surfaces. This is a better option than trying to grind a surface by hand as it is less time consuming.

 

The amount of time it takes to grind a surface depends on the skill of the user and the surface being ground. The best safety guideline with a surface grinder is to take your time. Most accidents happen by using the wrong blade with the wrong material or running the blade on the grinder faster than the speed it was meant to run at. A surface grinder can be used to prepare surfaces such as floors and sheet metal for cars.

 

How It Works

The typical surface grinder has a table that is capable of moving forward and backward as well as side to side. When moving side to side, the table uses hydraulics to move. The machine also has a grinding wheel that rotates and has an adjustable height. The grinding wheel is generally made of diamond, aluminum oxide, silicon carbide or cubic boron nitride. The majority of surface grinders used in the modern era are at least partially automated. The work material is held on the table of a magnetic chuck and sometimes an electro-magnetic chuck depending on the specific machine.

 

What a Surface Grinder Does To Material

A surface grinder produces a high level of heat which will create stress on the material. After being run through a surface grinder, a material will be more apt to breakage or fracture than before it was run through the machine. A material can also lose its magnetic properties if its temperature is raised too high.

What are CNC Tool and Cutter Grinder and Its Applications?

Today’s tool and cutter grinder is typically a CNC machine tool, usually 5 axes, which produces endmills, drills, step tools, etc. which are widely used in the metal cutting and woodworking industries.

 

Modern CNC tool and cutter grinders enhance productivity by typically offering features such as automatic tool loading as well as the ability to support multiple grinding wheels. High levels of automation, as well as automatic in-machine tool measurement and compensation, allow extended periods of unmanned production. With careful process configuration and appropriate tool support, tolerances less than 5 micrometers (0.0002″) can be consistently achieved even on the most complex parts.

 

Apart from manufacturing, in-machine tool measurement using touch-probe or laser technology allows cutting tools to be reconditioned. During normal use, cutting edges either wear and/or chip. The geometric features of cutting tools can be automatically measured within the CNC tool grinder and the tool ground to return cutting surfaces to optimal condition.

 

Significant software advancements have allowed CNC tool and cutter grinders to be utilized in a wide range of industries. Advanced CNC grinders feature sophisticated software that allows geometrically complex parts to be designed either parametrically or by using third party CAD/CAM software. 3D simulation of the entire grinding process and the finished part is possible as well as detection of any potential mechanical collisions and calculation of production time. Such features allow parts to be designed and verified, as well as the production process optimized, entirely within the software environment.

 

Tool and cutter grinders can be adapted to manufacturing precision machine components. The machine, when used for these purposes more likely would be called a CNC Grinding System.

 

CNC Grinding Systems are widely used to produce parts for aerospace, medical, automotive, and other industries. Extremely hard and exotic materials are generally no problem for today’s grinding systems and the multi-axis machines are capable of generating quite complex geometries.

How to Use a Surface Grinding Machine

A surface grinding machine is used to produce a smooth accurate finish on either metallic or nonmetallic materials. It uses a round rotating abrasive grinding wheel that remains stationary (but rotating) while the feed table (with work attached) is run in a reciprocating motion (left and right) under the grinding wheel. The specific amount of material to remove is determined by lightly touching off on the work with the grinding wheel rotating and feeding the grinding head down a certain distance.

 

WARNING: If a grinding wheel is permitted to exceed the maximum safe speed, it may disintegrate and cause injury to the operator and damage to the grinding machine!

 

On a Manual Surface Grinder, you will then need to run the table left and right with one hand wheel while cross-feeding with the other hand wheel.

 

On an Automatic Surface Grinder, you will then be able to run the table left and right automatically while cross-feeding automatically. All you need to do is set the down feed and stroke.

 

Typically surface grinders can grind within .0001 – .0002 but not all surface grinders are created equal. The less expensive models may not hold up to tool room accuracies but could be used effectively to sharpen punches, dies or do repair shop work. The more expensive models will use higher quality spindle bearings and other components and will be better able to attain tool room accuracies.

 

To use the surface grinding machines, you must select the correct grinding wheel for the work to be ground. There are different wheels that are best suited for grinding:

 

  • High Speed Steel RC 50-68
  • 400 Series Stainless
  • Soft Steels RC 30-45
  • 300 Series Stainless
  • Cast Iron: Ductile & Gray
  • Nonferrous Alloys

 

In each of the categories above you will need to determine wheel type by deciding if you need heavy (> .004), moderate (.002-.004) or light stock (.001) removal characteristics. Also, you will need to select a Grit size. 46 grit being for general purpose, 60 grit for commercial finish, 80 grit for fine finish and 120 grit for very fine finishes.

 

After selecting the correct wheel for your job, visually inspect the wheel for any damage or cracks. If no damage is found install the wheel on your surface grinder, tightening the left-hand spindle nut carefully with a spanner wrench. Make sure you replace the guard covering the wheel, put safety glasses on then turn the spindle on. Step away and let the spindle run for 1 minute to make sure the grinding wheel is running smoothly.

 

Once the grinding wheel has been dressed it is not recommended to turn the spindle off because turning off the spindle will require the wheel to be dressed again for some concentricity will be lost.

 

You are now ready to dress the wheel using a single point diamond dressing tool that is placed and held down by the magnetic chuck. A small amount of grinding wheel should be dressed off of the diameter in order to make the wheel run concentric. Place the diamond dresser under the rotating wheel and bring down the grinding head carefully so it just touches the dresser. Sweep the diamond dresser across the rotating wheel using the cross feed (y-axis). Feed the grinding head down .002 then sweep the diamond dresser across the rotating wheel. Repeat until the grinding wheel face is clean and running concentric.

 

After the wheel is dressed and running concentric you will then be ready to gently touch off on the work (using the spark or layout fluid method). Next, set your “zero” on the down feed handle, raise the head slightly to clear work then the cross feed handle to distance the work from the grinding wheel. Next feed the grinding head down a distance not more than .005. The amount of material being removed will determine how far you can feed the cross-feed in per pass.

 

The benefits of surface grinding are:

  • You can grind very hard or abrasive materials
  • High degree of dimensional accuracy
  • Produces surface textures of very high finish
  • Tooling is less expensive
  • Work holding is easier because of magnetic chuck
  • Can be done automatically

 

In short, you will most likely need a surface grinder if you need to provide precision ground surfaces, either for a high surface finish or attaining critical dimensions.

How to Choose the Right Grinding Machine for Your Business

Grinding cylindrical metals may look like a simple activity on the outside, but not choosing the right one may end up costing your business unnecessary time and money. Especially for bigger plants, the need to upgrade to a modern grinding machine may be very necessary. Although a lot of small scale grinding is still carried on through abrasive wheels, the convenience offered by the modern variants of Grinding Machines with diamond dressing easily outweighs older versions. So, what kind of machines should you actually buy? Well, here are a few handy tips.

 

Finding the ideal type

 

Although several types of grinding machines are produced and sold, the ones that are most widely available include internal, external and centerless external. Internal grinders are used for the inner diameters of cylindrical metal surfaces while external are meant for the outer diameters. Centerless external grinding machine basically consists of two grinding wheels which together grind the external diameters of cylindrical metal objects. Besides these, some specific types of machines for objects of specific shapes are also available. Most often a single machine is able to perform a specific kind of activity. Thus, depending upon what exactly needs to be grinded and on what volume, a business should be making the decision to buy the right kind of grinding machine.

 

The volume of grinding

 

For the small scale activities, smaller abrasive wheel grinding machines definitely would be compatible. However, for the large scale processes that typically require the processing of thousands of tons of metals every year, investing on a large scale machine could be worth the investment. That can save enormous time and effort on large scale grinding. With larger wheels, such can easily process larger objects at a fraction of time compared to smaller manual abrasive grinding.

 

The technology and manpower available

 

While a lot of activities still require some kind of manual involvement, several modern variations of machines have specific automated features that typically require much less manual contribution. Depending upon the availability of skilled labor, as well as wages the decision regarding the ideal grinding machine to be purchased should be made. Especially when labor costs are high or labor is deficient, investing on a semi-automated grinding machine would be a beneficial decision. Considering the fact that the environment is typically one of the most hazardous environments for humans, several plants are already investing on automation or semi-automation of grinding processes. For businesses that are particularly willing to adapt the best safety standards in their industry, specific models with advanced safety features like bulletproof glasses and partial automation are also available.

 

High efficiency grinding machines are among Chevalier’s impressive range of Falcon Machinery Tools. Like all of Chevalier’s products, every single one of the grinding machines are intricately designed to totally accommodate the infinite demands that high mix production places on businesses of any size, no matter how big or small.

Overview of CNC Tool and Cutter Grinder

A tool and cutter grinder is used to sharpen milling cutters and tool bits along with a host of other cutting tools.

 

It is an extremely versatile machine used to perform a variety of grinding operations: surface, cylindrical, or complex shapes. The image shows a manually operated setup, however highly automated Computer Numerical Control (CNC) machines are becoming increasingly common due to the complexities involved in the process.

 

The operation of this machine (in particular, the manually operated variety) requires a high level of skill. The two main skills needed understand of the relationship between the grinding wheel and the metal being cut and knowledge of tool geometry. The illustrated set-up is only one of many combinations available. The huge variety in shapes and types of machining cutters requires flexibility in usage. A variety of dedicated fixtures are included that allow cylindrical grinding operations or complex angles to be ground. The vise shown can swivel in three planes.

 

The table moves longitudinally and laterally, the head can swivel as well as being adjustable in the horizontal plane, as visible in the first image. This flexibility in the head allows the critical clearance angles required by the various cutters to be achieved.
