Show Me a Surface Grinder

A grinder is a heavy-duty machine used to remove material from the surface of a workpiece. There are several different types of grinders, each of which works differently. In this article, we will show you the advantage of surface grinder.

Not to be confused with a milling machine, a grinder is a heavy-duty machine used to remove material from the surface of a workpiece. The rotating cutting tool of the milling machine is placed on the stationary workpiece, and the rotating grinding wheel of the grinder is also placed on the stationary workpiece. However, there are several different types of grinders, each of which works differently.


Desktop Grinder

The desktop grinder is characterized by its desktop shape. They usually have two different grinding wheels: one for removing material and the other for finishing. They are called "bench grinders" because their grinding wheels are fixed on the top of the table. As a result, the bench grinder is easy and convenient for manufacturing workers.


Belt Grinding Machine

Belt grinders are characterized by the use of a belt grinder. Like other grinders, they are designed to remove material from workpieces, keeping the workpieces smaller and having a smoother and more desirable surface. In the case of belt grinding, the belt is coated with an abrasive, after which it reaches the surface of the workpiece until the desired results are obtained. Belt grinding is most commonly performed on metal workpieces, although it also handles components made of other materials.


Surface Grinder

The third type of grinder is the surface grinder. Surface grinders are unique because they have an adjustable head. The head on the surface grinder can be lowered into the workpiece. Once lowered, the head can then rotate back and forth under the machine's grinding wheel.

While belt grinders are usually used for the finishing processes, surface grinders are the most commonly used material removal. When compared to other grinding machines, surface grinding machines are able to remove significant amounts of material, making them desirable for such applications.

Gear Grinding Machine

Gear grinders are designed specifically to remove material from shafts. By using grinding wheels, they can grind the center of the shaft with extreme precision.


Die Grinder

A smaller and more basic type of grinder is a matrix grinder. Unlike the other machines mentioned here, die grinders are hand-held. They are connected to an air compressor that powers the machine's grinding wheel. If an air compressor is not used, the grinder will likely receive power from the electric motor.



The aerospace industry is known for machining materials that are difficult to machine with conventional cutting tools and processes. These tough and high temperature resistant materials allow the components to survive the harsh conditions of aircraft engines. However, the same features that make these materials difficult to machine are likely to make them suitable for grinding. Turbine rings, turbine shafts, and inner and outer rings are a few of the aerospace components which are commonly precision ground.


Machine Tool Manufacturers

Machine tool builders use main shafts, linear guides, ball screws, indexers and Hirth couplings in turntables, roller bearings, cams, racks, valve cores and grounded parts for pistons.


Mold Industry

The mold industry uses grinding to produce thread dies, stamping dies, bending machines, wire drawing dies, rolling dies and inserts, and many other mold components.

The tool industry that supports the mold/mold and machine tool industries uses precision grinding to produce three- and four-jaw chucks, shaped blades, step drills, drill tips, reamers, taps, ring gauges, and chucks. ISO and HSK adapters and tool holders for tool holders also require grinding.

Note that when milling or turning with conventional machines and tools, part tolerances and surface quality deteriorate as the tool inserts wear. In contrast, the wheel can often be machined to maintain the sharp cutting edges of the abrasive and the shape of the wheel, resulting in a consistent finish and high dimensional accuracy.

Surface grinding is the most common type of grinding process. It is a piece of heavy industry equipment where different types of metal and non-metal objects need to be refined and smoothed for finishing. This is most often seen in the automotive industry. The surface grinder consists of a table with a grinding wheel above it. A device called a fixture holds the workpiece, called the workpiece. The holders can be magnetic, vacuum or mechanical, depending on the composition of the workpiece.


Three Basic Types of Surface Grinders

There are three basic types of surface grinders: horizontal, vertical, single disc and double disc grinders. Each machine is best suited for specific items. The main difference is how the grinding wheel makes contact with the workpiece.

Horizontal spindle grinders, also known as peripheral grinders, are best suited for high-precision work, such as angular or conical surfaces, grooves, or recesses. The flat edge of the circle - the rim - is in contact with the part. Pins, pistons, connecting rods and bearing races are examples of elements ground on this type of machine.

Vertical spindle grinders or disc grinders are usually used to remove material quickly. The face of the grinding wheel is lowered onto the workpiece below. Vertical spindle grinders are best for stators, plates, rotors, gears, inner rings and inner plates, and stops and spacers.

Single disc grinders and double disc grinders are available for both horizontal-spindle and vertical-spindle styles. Disc grinders have a larger contact area between the grinding surface and the workpiece, and can grind both sides at once. Some rotors, plates, spacers, gears, and washers can be put into disc grinders.
