The Ways to Improve Grinding Efficiency of CNC internal grinding machine Feb 07, 2018

CNC internal grinder is to improve the grinding efficiency as the main objective of the development of the grinding process to become efficient grinding. CNC internal grinding grinder is mainly to grinding the inner hole, the inner cone hole and other shapes of the workpiece. In real life, such as bearing bore, etc., can be used to grind this internal grinder, grinding can improve the efficiency and accuracy. CNC internal grinding machine applicable to all types of air-conditioning compressor grinding, bearing processing industry, all kinds of workpiece grinding, machining and grinding all types of automotive parts, all kinds of high-precision, ultra-high precision marine components Through hole, blind hole, stepped hole, tapered surface, end surface, tapered hole, spherical stainless steel piston rod grinding. CNC internal grinding machine efficient grinding technology what?

Superabrasive and jog grinding processes are comparable to milling, pulling pins, planing and, in some cases, turning, both technically and economically. With the advent of new materials such as ceramic, whisker reinforced and reinforced polymeric materials, multilayered and non-metallic laminates, CNC internal grinding machines are often the only viable process. How to improve the efficiency of CNC grinding machine?

There are three main ways to improve the grinding efficiency of CNC internal grinder:

1. CNC internal grinding machine with high-speed grinding, grinding wheel speed, grinding unit is the number of grinding particles per unit time increased.

2. Application of slow to strong grinding, increasing the wheel radial feed (ie, grinding depth), coupled with a slow workpiece feed rate, thereby increasing the number of simultaneous participation in cutting abrasive.

3. CNC internal grinding machine with abrasive belt grinding and wide grinding wheel to increase the grinding width to increase the number of grinding involved in the effect of grinding.

CNC grinding machine features high-speed grinding:

CNC internal grinding machine high-speed grinding is to improve the grinding efficiency of one of the important ways. CNC internal grinder high-speed grinding is grinding wheel speed above 50m / s, grinding wheel speed compared with the conventional internal grinder grinder grinding mode compared to CNC internal grinder high-speed grinding with The following features:

1. Grinding wheel speed is high, CNC internal grinder in the grinding process, as a cutting tool grinding wheel is a very high speed of the workpiece cutting. CNC internal grinding machine high-speed grinding, wheel speed can be as high as 200m / s, which is different from the NC grinding machine grinding different from the important characteristics of ordinary grinding.

2. CNC internal grinding machine grinding efficiency, grinding wheel speed will increase the single cut into a smaller depth. This is mainly due to the fact that as the speed of the workpiece and the penetration depth remain the same, as the speed of the grinding wheel increases, it means that more abrasive particles will be used to cut the same amount of workpiece material.

3. Improve the durability of the wheel, due to the thinning of each abrasive grain cutting. The reduction of the cutting load on each abrasive grain results in a relatively long time for the abrasive particles to maintain their cutting power, resulting in increased wheel durability.

4. Improve the NC grinding machine parts machining accuracy, high-speed grinding in the grinding force decreased, so that the deformation of the workpiece to reduce, which will make the workpiece machining accuracy to some extent improve. On the other hand, the service life of abrasive tools increases, and the wear rate slows to maintain the profile accuracy of the abrasive tools, thereby improving the machining accuracy of the parts.

5 to improve the surface quality of the workpiece, if you maintain the same amount of feed with ordinary grinding, as the grinding wheel speed increases the thickness of each abrasive grain thinning, which means that CNC grinding machine through the grinding area in the workpiece The depth of the scar left on the surface is reduced, thus reducing the surface roughness.

In addition to the CNC internal grinding machine with a common type of internal grinder structural characteristics, but also has the following structural features: 1. Workbench smooth low-speed movement; 2. CNC internal grinder head spindle can stepless speed regulation; To; 4. CNC internal grinder with coolant precision filter device.
