CNC internal grinding machine is an efficient grinding process which is developed by improving grinding efficiency.CNC internal grinding machine is mainly used to grind the round hole, inner taper hole and other shape of the workpiece.In the real life, such as bearing inner hole, can be used to polish the internal grinding machine, which can improve the efficiency and precision of grinding.CNC internal grinder is suitable for the air conditioning compressor and machining of grinding, bearing all kinds of industries of all kinds of artifacts of all kinds of car processing and grinding, the ship's spare parts, all kinds of high precision, high precision of hole, blind hole, the ladder hole, cone, end face, taper hole, stainless steel piston rod of spherical grinding processing.What is the effective grinding technology of CNC internal grinding machine?
Super hard abrasive and slow feed grinding process can be compared with milling, pulling, planing and in some situations, whether from a technical or economic point of view.With the development of new materials (such as ceramic, whisker reinforced metal and strengthen aggregation of multi-layer metal and non-metal materials, bonding materials), CNC internal grinder is often the only feasible processing method.How to improve the efficiency of CNC internal grinding machine?
There are three main ways to improve the grinding efficiency of CNC internal grinding machines:
1. CNC internal grinding machine adopts high speed grinding, which increases the speed of grinding wheel and increases the number of grinding grains in the grinding area in unit time.
2. Apply slow feed to strong grinding, and at the same time increase the radial feed amount of grinding wheel (that is, grinding depth), with slow workpiece feeding speed, so as to increase the number of grinding grains involved in cutting.
3. CNC internal grinding machine adopts abrasive belt grinding and wide grinding wheel to increase the grinding width to increase the effect of grinding grain number.
Characteristics of high speed grinding of CNC internal grinding machine:
CNC internal grinding machine is one of the important ways to improve grinding efficiency.Internal grinder CNC high speed grinding is in more than 50 m/s grinding wheel speed, wheel linear velocity of around 30 m/s, compared to normal internal grinder grinder grinding way high-speed grinding CNC internal grinder has the following features:
1. The speed of grinding wheel is high. In grinding process, the grinding wheel of cutting tool is used to cut the workpiece at extremely high speed.The speed of grinding wheel can reach up to 200m/s in high speed grinding of CNC internal grinding machine, which is an important characteristic of high speed grinding different from ordinary grinding.
2. The grinding efficiency of CNC internal grinding machine is high, and the improvement of grinding wheel speed will make the cutting depth of single abrasive grain smaller.This is mainly due to the fact that the speed of the workpiece and the cutting depth remain unchanged, because the improvement of the grinding wheel speed will mean that more abrasive particles are removed as much as the workpiece material.
3. Improve the durability of the grinding wheel, because the cutting thickness of each abrasive grain is thinned.The cutting load of each grinding grain is reduced, resulting in a relatively prolonged period of time for the abrasive to maintain the cutting ability, thus improving the durability of the grinding wheel.
4. Improve the machining accuracy of CNC internal grinding machine parts, reduce the grinding force in high speed grinding, and reduce the deformation of the workpiece, which will improve the machining accuracy of the workpiece to a certain extent.On the other hand, the service life of the grinding tool increases, and the wear speed is reduced so that the contour accuracy of the grinding tool can be maintained, so that the machining accuracy of the parts can be improved.
5. Improve the surface quality of workpiece, if keep as same as ordinary grinding feed, with the improvement of grinding wheel speed enables each abrasive cutting thickness thinning, which means that the CNC internal grinder by grinding area in the surface grinding crack depth is reduced, thus reducing the surface roughness.
In addition to the structure characteristics of common internal cylindrical grinder, CNC internal grinding machine has the following structure characteristics: 1.2. CNC internal grinding bed spindle can be stepless speed adjustment;3. Transverse microfeed;4. CNC internal grinding machine has the precision filtering device of cooling liquid.
