Precision Surface Grinder

Among all precision machinery in metal processing field, high precision surface grinding machine is one of the most important one in the entire processing process. For precision surface grinding, the concept of a surface grinder refers to the mechanical grinding of the flat surface side of the objects, and this grinding process may be one of the most difficult grinding processes in metal. Due to many technical issues that affect the final tolerance, it has led to the development of the work industry.
 
In conventional process, after cutting and other complex processing, many work pieces would go to step of precision surface grinding for further finishing. A precision surface grinding machine is adopted to create smooth finished surface on either flat or other specific profile surfaces. It is a widely applied abrasive cutting process by which a high torque spinning wheel is covered in rough particles named grinding wheels that cuts chips of metallic or nonmetallic substance from a clamped work piece, rendering a flat and smooth face. Among all the grinding processes, precision surface grinder is one of the most general grinding machines since this procedure is very critical.

CNC Controlled Precision Grinding

The CNC precision surface grinding machines are usually equipped with humanized operation panel, which can ensure that the grinding movement is accurately displayed under the control of the computer program. The friendly human machine interface not only ensures the grinding quality of precision surface grinder, but also provides great convenience for users on the manufacturing site under many different conditions. With the help of modern programming technology, operators of precision surface grinder today only need to call the corresponding cutting program from the machine's memory, and the machine will be processed with appropriate movements.

In addition to the CNC technology introduced in the grinding machinery, there is another technology that contributes to the grinding process. Because a large number of grinding wheels are in contact with the surface of the workpiece material, rotary surface grinding is a very effective method. For each rotation of the rotary table, the entire surface to be ground is in contact with the surface of the grinding wheel. There are many applications that require custom options or electromagnetic, mechanical, vacuum, pneumatic, or hydraulic fixtures. Many manufacturing teams work exclusively with members of their manufacturing or engineering teams to produce work clamping equipment to meet customer manufacturing procedures and obtain repeatable quality, accuracy, and productivity.


Grinding Speeds

In addition to the productivity that is important to manufacturers, variable speed rotary tables are standard with variable force electro-magnetic chucks and electronic sensed. Due to spindle vacuum, pneumatic or hydraulic pressure is the configuration feature of most rotary surface grinders in the market today. Surface grinding is the most common grinding operation, and it is a finishing process that uses rotating grinding wheels to smooth the surface. By removing the oxide layer and impurities on the outer of the workpiece, the surface of the metal or non-metallic material is more beautiful. For functional purposes, the grinding process will also obtain the desired surface. The precision surface grinder is composed of grinding wheel, workpiece fixing device (called chuck with cylinder power) and reciprocating or rotary table. This is an arrangement. Also, the chuck item will hold it in place when processing materials.

Moreover, it can be operated in one of two ways: fixing the ferromagnetic pieces in place by magnetic chucks, and fixing the non-ferromagnetic and non-metal pieces in places by vacuum or mechanical means. Regarding the vice, if there is only an electromagnetic chuck, a machine vice placed on the electro-magnetic chuck can be used to hold the non-ferromagnetic workpiece. The influencing factors to be considered in surface grinding are the material of the grinding wheel and the material of the workpiece to be processed. Compared with some specific grinding situations, typical workpiece materials include cast iron and low carbon steel, and these two materials will not block the grinding wheel during processing. Other materials to be ground are aluminum, stainless steel, brass and some plastics, and the last one is at least to be conducted because it can be well managed by other mechanisms.


Temperature

During operation, once the grinding is at high temperatures, the material tends to become weakened and is more inclined to corrode. This can also result in a loss of magnetism in materials where this is applicable. The grinding wheel is not limited to a cylindrical shape and can have a myriad of options that are useful in delivering different geometries to the object being processed by the precision surface grinder.
