NC Surface Grinder

In the field of metal grinding, NC-based surface grinding is very unique, because cylindrical grinding and roll grinding differ from surface grinding for various reasons. The grinding head of surface grinding moves down to the workpiece, and the workpiece can move back and forth, so the worktable is usually equipped with a controllable magnetic stock or vacuum chuck. In the most common case, a surface grinder has a grinding wheel that rotates along a horizontal axis, and grinding is performed on the outer periphery of the grinding wheel. For rotary surface grinders, which commonly known as Blanchard type grinders, there is a grinding head that controls the grinding wheel to rotate along a vertical axis and grind with the end face of the grinding wheel, while the worktable rotates the workpiece in the opposite direction.

This type of machine can remove large amounts of material and proceed the grinding process on flat surfaces with obvious spiral grinding marks. It can also be used to make and sharpen metal stamping dies, flat shear blades, fixed bases or any flat surface that needs to be processed under well-controlled management according to order specifications. The grinding of the metal surface can be conducted by manual operation or NC, CNC systems, depending on the operators’ requirements.


Semi-automatic Controlling System

If people think that intelligent technology plus CNC machine tools can achieve automated manufacturing, the NC controlled machine is often equipped with humanized operation mechanical panels with some digital elements for multiple machining tasks, which can precisely display various processing missions. In addition, the friendly NC interface not only ensures accurate grinding operations, but also makes the surface treatment more efficient, because with the NC-controlled interface. The grinder operator only needs to call the programs that have been set up and stored well in the system stores, so the machine will automatically execute the grinding process.
In addition to suppliers in Germany and Japan, there are many cutting-edge grinding machine suppliers in Taiwan. They can provide comprehensive grinding solutions for industrial users worldwide and in the entire industrial field, including grinding machines equipped with NC or PLC control systems. Many international grinding machine manufacturers are experts, who understand the technical issues of customers better than their customers in the market, such as the grinding accuracy value of the target material and the corresponding efficiency.

Other Important Variables

In short, surface grinding is the process of removing surface burrs through a large area of the grinding wheel and evenly contacting the surface of the workpiece. There are many types of rotary table for workpieces, including electromagnetic, mechanical, vacuum, pneumatic or hydraulic clamps. These are also important grinding variables in the grinding process which will ultimately affect the final output of the machine.
Many grinder manufacturers have specifically designed and produced workpiece fixtures to meet customers' various processes, and they have successfully achieved the expected accuracy and efficiency. Among them, the variable speed rotary table is a standard accessory with variable force electro-magnetic chuck and electronic induction function. A surface grinder is composed of grinding wheel, workpiece holding device and reciprocating table. During the processing, the fixture fixes the workpiece in the proper position. There are two clamping methods according to the fixture. One is a ferromagnetic workpiece, which uses electromagnetic The chuck holds the workpiece in place, and the other is a vacuum or mechanical method, which is a very popular method.



For the comprehensive use of these accessories, when using an electromagnetic chuck, a vise can be installed on the electromagnetic chuck to fix the non-ferromagnetic workpiece. The clamping mechanism is essential for the entire machining process. Rigid and precise workpiece positioning can accurately complete all processing tasks and obtain ideal output. The factors to be considered in surface grinding also include the material of the grinding wheel and the material of the workpiece. Common workpiece materials include aluminum, brass, steel, cast iron, and mild steel. Some of them are more stable and will not corrode and adhere to the grinding wheel during processing, while some may corrode during the processing and then adhere to the surface of the grinding wheel. The matching of these types of materials in multiple stages will be reduced. On the other hand, the grinding wheel may have various shapes. Machine operators can dress wheels according to specific grinding requirements. It is worth noting that in the surface grinding process, the shape of the grinding wheel will affect the reverse shape of the workpiece, so the operator must always pay attention to the change in the shape of the workpiece in order to repair the workpiece immediately. The grinding wheel maintains working accuracy.


Smart Grinding

Like other manual grinders, NC-based surface grinders will still have their market share in the industry. In the metal processing industry, there are always different requirements for processing needs, so the varieties are largely different.
