Equipment Highlights

Equipment Highlights

(1)YH2M-8195 vertical single-sided grinding (polishing) machine is a water-cooled four-station single-sided grinding (polishing) machine. The working rings on the four stations are driven to rotate by four independent speed regulating motor transmission systems respectively, and the four pressurizing cylinders drive the universal pressure plate through the piston rod expansion and contraction to reliably pressurize the workpieces of the four stations respectively.

(2) by precision pressure reducing valve and electric proportional valve precise control processing pressure.

(3) This machine is equipped with a peristaltic pump. According to the different processed workpieces, it can accurately control the drip flow of grinding (polishing) liquid to achieve better grinding (polishing) effect.

(4) PLC control, flexible and reliable control mode.

(5) The touch screen is used as the man-machine interface to display real-time information of alarm and machine tool status; the interface is friendly. Large amount of information.
