CNC Double Face Grinder

MKY7650B MKY7660A MKW7650B MKZ7650B Double Face Grinder

Product Introduction

CNC horizontal axis double face grinding machine is a kind of efficient surface processing grinder, which can process two parallel surfaces of workpiece at one time. According to the shape and specification of the workpiece, it can be equipped with the corresponding automatic loading and unloading mechanism, which has a high degree of automation and is suitable for batch processing of parts. This series of machine tools are equipped with GSK986 CNC system. The automatic cycle grinding and automatic dressing of grinding wheel can be realized by controlling the left and right grinding heads, feeding mechanism and dressing device separately or in linkage.

According to the different feeding methods, this series of machine tools can be divided into disc feeding, through feeding and reciprocating feeding. With the same feeding mode, different workpiece special fixtures can be replaced, and different specifications of parts can be processed with high flexibility. It is mainly applied to the processing of bearing ring, connecting rod, compressor slide, gear pump blade, piston pin, cross shaft and other parts.

Product Features

■ The main large parts of the machine tool are made of high-quality castings, which have been artificially aged twice. It has good anti-seismic and shock absorption characteristics and high stability.

■ The feed form of the machine tool is moving carriage. The moving guide unit of the carriage adopts high precision rolling linear guide pair, which has good guide precision, high rigidity and maintenance free.

■ The high precision ball screw pair is used in the carriage moving feed unit, and the pitch error compensation and reverse clearance compensation of the ball screw can be carried out through the numerical control system, so that the feed unit has high positioning accuracy and repeated positioning accuracy.

■ The spindle is supported by high-speed angular contact ball bearing or the combination of high-speed angular contact ball bearing and double row cylindrical roller bearing, which has high rotation accuracy and good rigidity, and can bear the combined radial and axial load.

■ The machine tool has the function of automatic grinding wheel dressing, and can also trim both sides of the left and right grinding wheels. By adjusting the speed of the swing arm or the speed of the grinding wheel, the roughing and finishing of the grinding wheel can be realized. In addition, through grinding counting, it can automatically prompt dressing wheel and grinding automatic compensation.

■ The electric cabinet of machine tool is equipped with air conditioner to avoid the influence of heating and temperature rise of electrical system on the system. The electrical cabinet adopts slot board wiring structure. The layout and wiring of components are reasonable, neat, beautiful and easy to maintain. The cabinet is equipped with a full set of internal lighting, debugging socket and other related ancillary facilities. The machine tool is equipped with safety warning light.

■ The cooling mode of the machine tool is water cooling in the center of the spindle, cooling the grinding area and spindle components in time, effectively controlling the thermal deformation of the spindle and workpiece grinding, and fully ensuring the grinding accuracy of the workpiece.

■ The left and right grinding heads can make angle adjustment according to the grinding accuracy requirements and grinding allowance of the workpiece, so as to realize rough grinding, fine grinding and smooth grinding of the workpiece and fully ensure the grinding accuracy of the workpiece.
