The 2MK2218x50A and 2MK2225x70 series vertical CNC inner circle honing machines are the new generation CNC grinding machines developed by our company in accordance with the national science and technology major special project. This machine tool adopts a dedicated CNC honing control system developed by Guangzhou CNC for our company, combined with a dedicated control module developed by our company, to form a new international honing machine spindle reciprocating digital control system. The maximum reciprocating acceleration of the spindle reaches 2.5g and has obtained 8 national patents. This CNC system can control five axis output. The first axis controls the reciprocating motion of the main shaft, which is based on the principle of servo motor driving servo hydraulic valve to achieve high speed and high acceleration of reciprocating motion, as well as control of position accuracy. And it can achieve precise short stroke honing: the second axis is controlled by a servo motor to rotate the machine spindle, which can achieve infinite speed regulation, and can be linked with the first axis to achieve any mesh angle of the cylinder hole; The third axis is used to control the CNC worktable, achieving precise position control of the worktable; The other two axes can achieve control of rough and fine honing pressure. The machine tool is equipped with a standard dual feed mechanism and an automatic measurement system, which can achieve flat top mesh grinding processing. The machine tool adopts a modular design as a whole, and can provide various high, medium, and ordinary grade configurations to meet the needs of different customers for honing machine tools. Suitable for precision machining of various automotive engines, cylinder liners, and other types of through holes and holes with a height of less than 500mm. This machine tool can be used independently or integrated into automatic production lines for various parts, making it an essential equipment for honing and an ideal replacement for imported products.
