Three-axis CNC surface grinder MK820 MK1022 MK1224 MK4080
1.Having reasonable structure,high rigidity,good looking and operating easily.
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 positioning,automatic feed and fast forward and rewind functions.
3. Longitudinal movement (left and right) adopts a flat -type rail guide and controlled by servo motor
4.Vertical movement is transmitted by precision shaped screw and driven by servo motor which can ensure precision,accurate positioning,automatic feed and rapid up and down function.
5.Adopting SIEMENS CNC SYSTEM which has high degree of automation.
