Guide of Surface Grinder: How Does Surface Grinding Machine Works and Its Evolution

Surface grinding is an abrasive process. It involves securing the object to a device that will hold it in place (a chuck) before slowly moving the object’s surface across a grinding wheel that’s spinning really fast. This will generate a flat plane wherever the machine comes into contact with the object. It also gives the object an even finish. The longer the wheel spends working on the cutting depth, as well as using a surface grinding wheel with a higher grit count will further improve the surface’s finish. By slowly increasing the depth of the cut the machinist will be able to achieve these things.

 

Introducing the Surface Grinder

The surface grinding machine is the most common type of grinding machine found in any shop. You can actually compare it to milling cutter that has multiple teeth but the surface grinding machine has a grinding wheel, which makes it an abrasive cutting tool. The wheel is used to remove really small pieces of metal (known as swarf). It works because the wheel is made up of thousands of cutting edges.

 

These surface grinding tables are used for several different purposes including removing excess material. They work really well on very hard materials (i.e. steel, diamonds) to produce a very high quality finished surface.

 

How a Surface Grinding Machine Works?

The surface grinding machine’s chuck moves back and forth once the table has raised the object so that it’s slightly deeper within the wheel. There are intervals that can be set (i.e. 0.001 inches / 0.0254 mm) with each pass. As the grinding wheel rotates with its abrasive particles small amounts of the object’s material will be removed each time in order to create a flat surface. For this reason, the surface grinding process is usually a finishing step that’s designed to bring an object to a certain tolerance but the procedure is often followed up with a polishing procedure during the grinding-and-lapping process.

 

Evolution of the Surface Grinder

Over the course of time, the surface grinding machine has evolved. Today there are even some machines that are ergonomic, as well as those that are portable. Computer Numerically Controlled (CNC) grinders are also available. Regardless of the type of machine you choose to use, it will be controlled by a computer interface today.

 

Materials Used In a Surface Grinder

There are 2 types of abrasive materials that are used within the grinding wheel:

 

  1. Aluminum oxide is used whenever the materials that are being ground have a high ductility or the ability to permanently become deformed.

 

  1. Silicon oxide is used whenever the materials that are being ground have a low ductility.

 

Regardless of what type of material you’re grinding (i.e. steel, aluminum, glass) the machine’s abrasive grains will allow for a smooth finish. Usually these abrasive grains are coated with diamonds.

 

Types of Surface Grinders

A grinding wheel has a doughnut-like design. The hole in the middle slides down over the top of a metal rod (spindle). Today these machines are being made by lots of different manufacturers and so there are a lot of different models available to choose from. Nevertheless, they still use one of the following types of structure:

 

  1. A vertical spindle design has a spindle that’s pointing straight up and down. The grinding wheel itself lays flat on its face at the bottom of this spindle so that the wheel’s full width can be utilized in grinding the object. Typically, this type of design is used whenever working on larger panels or sheets of materials or whenever there’s a lot of materials that need to be quickly ground.

 

  1. A horizontal spindle design has a wheel that’s suspended over the table. Only the wheel’s flat, outside edge will come into contact with the object that’s being secured by the chuck. Thanks to the smaller grinding surface it’s possible to have great precision whenever you’re making a cut, which is why they’re typically used whenever small features (i.e. angles, profiles) are needed.

 

In the same way as there are 2 common types of spindles, there are also 2 common types of surface grinding machines, both of which only grind flat surfaces. These include:

 

  1. Planer grinders keep the grinding wheel in one place while the worktable around it is being moved, creating a reciprocating back-and-forth motion that can be controlled either manually or via a mechanic or hydraulic drive mechanism. The spindle that’s used to rotate the grinding wheel can be placed either vertically or horizontally.

 

  1. Rotary-type grinders have circular shaped worktables that revolve, as does the grinding wheel itself. They can be either vertical or horizontal.

How to Use a Tool Grinding Machine

Tips! Do you know what you’ll need when you use a tool grinding machine? Tell you some essential tools below:

 

  • Heavy Work Gloves
  • Tool And Cutter Grinder Machine
  • Tools To Sharpen
  • Safety Glasses

 

 

Usage of Tool Grinding Machine

A tool and cutter grinder is used to sharpen the edges of tools that have gone dull. The tool grinding machine is not a toy and takes special care and training in order to operate correctly. The tool and cutter grinder is also a rather large machine found in machine shops. It is recommended to take your tools to a professional to grind and sharpen them. The following article will explain how a professional operates a tool grinding machine.

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. If you are interested in learning more information about end mill series, try to visit Earth-Chain’s website to see what products and details they can offer you.

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.
