Equipment Highlights

Equipment Highlights

(1) This machine belongs to the grinding machine of the motion principle of 4 planetary gear trains.

(2) The sun gear in the main transmission component of this machine is equipped with a two-stage speed change device, and the two speeds of the sun gear can be obtained by pushing the shift fork through the speed change cylinder.

(3) the use of frequency converter speed control, start and stop smooth, no impact.

(4) Adopt timing control, when the machine reaches the preset grinding time, it will automatically stop. At the same time, the machine has the function of counting the number of workpieces, which can record the working efficiency of each shift.

(5) The machine tool is equipped with a variable pressure mechanism for pressure grinding of the workpiece.

(6) This machine is equipped with a safety self-locking cylinder.

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

(8) Use a text display to display real-time information of alarms and machine tool status; the interface is friendly and the amount of information is large.

(9) The control components are all 24VDC power supply, which improves the safety of the machine tool.
