Model： MYK820
Type： Hydraulic CNC grinder
【Instruction】
1. The machine has reasonable structure , adopting cross saddle structure, good rigidity, beautiful appearance, convenient operation；
2. 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.
3. Longitudinal movement (left and right) adopts a flat -type rail guide,hydraulic transmission and artificial precision scraping which can achieve stable running.
4. Vertical movement of the grinding head is transmitted by precision shaped ball screw and driven by servo motor which can ensure precision,accurate position,automatic feed and rapid up and down function.
5. Adopting GSK system,two-axis CNC which can program freely according to the actual situation and install Pulse hand wheel according to customer’s requirement；
6.The machine is totally enclosed housing which can completely cover the entire work area and effectively prevent the coolant and iron splash.In addition,we can install fog dust suction device according to the demand of the customers。(Optional)
7. 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.
