Grinding Tools and Their Types

A rotating disk surface grinder is the most popular type of grinding tools. This type of abrasive grinding tool generates high-quality results and high speed performance. The rotary power of such machines helps in removing minute sized impurities from workpieces. It can even remove larger contaminants and chips.

A grinding wheel utilizes the power of electromagnetic energy to turn at a high rate of speed. It can perform both wet and dry grinding operation. It is widely used in cutting wheels for grinding metal and non-metal workpieces. The grinding wheel uses two or more rotating cylinders that can spin at a very high speed. In order to provide a durable surface, the surface grinder must be well-made and properly installed.

A non-metallic abrasive wheel, also known as a magnetic chuck is also called a metal press. This type of grinder works by using electromagnetic energy to transfer workpieces into a stationary magnetic field. This provides a stable and powerful source of force. It has excellent wear tolerance, high speed and excellent power with a low profile.

Spindle-driven surface grinders operate with the help of a fixed or adjustable spindle. The spindle is fixed above the work piece and the chuck spins the wheel at a definite rate. The chuck is rotated by a fixed drum and it is powered by a motor. The range of operations and speed of such machines is different. However, they are used in grind, die cutting, polishing, and other similar work processes.

Larger surface grinders, which are also called full-scale grinders, are used in the grinding of larger machining pieces. These machines are generally mounted on a stand. The work piece can be manually moved across the grinding wheels with the help of a pinion or rack system. This enables the worker to perform a wide range of rotating operations including face removal, grinding to a specific depth, and others. They can even change the speed of the grinding wheel to suit the changing machining conditions.

It is important to note that the workpiece must remain centered during the operation of any surface grinding wheel. If the workpiece is moved while the grinding wheel is in operation, the grinding action may damage the workpiece. A magnetic or electric motor grinder operates in a similar fashion. They can be used either electrically or magnetic.

A non-ferromagnetic surface grinder has a permanent magnet structure while a magnetic chuck has a non-magnetic component. The chuck functions in a similar manner as the magnetic chuck. They both use magnetic energy to drive a brush that removes workpiece material. However, the electrical surface grinder is more powerful than the magnetic one. In addition to the large chuck, it is possible to mount the unit on a stand.

Today’s modern technology has enabled the machining industry to incorporate a variety of surface grinding techniques to their workflow. Each type of grinder will require different attachment hardware depending upon the work required. For example, the CNC machine is commonly attached to a lathe or workbench in order to grind precise profiles. A CNC milling machine is also an option. It operates in the same way as the CNC surface grinder but with a higher level of precision.
