Model： MYK4080
Type： Hydraulic CNC grinder
【Instruction】
1、The machine has reasonable structure ,heavy weight, adopting cross saddle structure, good rigidity, beautiful appearance, convenient operation.
2、The machine body,cross carriage,column,working table and grinding head shell are made of resin sand and processed by aging to prevent deformation.
3、The guide rail is pasted and plastic, processed by artificial precision scraping so that the wear of the guide rail is reduced and the processing precision is ensured and extended.
4、Vertical movement is transmitted by turbine worm which can reduce the decline caused by the weight of the big grinding head and make grinding head have stable feed and protect the guide screw .
5、Transverse movement(front and rear) of work table is driven by servo motor and transmitted by precision ball screw which can ensure precision,accurate position,automatic feed according the program and fast forward and rewind functions
6、 Longitudinal movement (left and right) adopts a flat -type rail guide,hydraulic transmission and artificial precision scraping which can achieve stable running.
7、Vertical movement of the grinding head is driven by servo motor which can ensure precision,accurate position,automatic feed and rapid up and down function.
8、Adopting GSK96 system,two-axis CNC which can program freely and install pulse hand wheel according to the actual situation, X and Z axis feed can easily be free to switch；
9、The machine can achieve triaxial fully automatically. Although two-axis CNC Surface Grinder can help to reduce labor intensity of the operators，it still belongs to single person stand-alone operation.However, as for triaxial fully automatically surface grinder，a worker can operate 3 to 5 machines at the same time which reduces the labor cost greatly especially for batch processing which can achieve more benefits.
