Cylindrical grinding machine for internal and external grinding M1420 200*500mm (China)

Cylindrical grinding machine for internal and external grinding M1420

 

1. The machine is in mainly used for grinding small shafts, cylindrical

cartridges needle valves, pistons and other conical and spherical

surfaces. Item is attached trehkanatnoy clamping cartridge,

collet cartridge and special grippers. The machine is widely

used in the manufacture of parts for instrumentation, automotive

industry electromechanics, podshipnikovaya, textile

industry shipbuilding and the production of sewing machines and

different kinds equipment.

2. Speed feed the grinding head can be adjusted: gross speed: 0,01 / 0,02 / 0,03 / 0,04 mm, fine feed speed: 0,0025 / 0,005 / 0,0075 / 0,01 mm.

Total the feed value can be set by adjusting the stop dog

3. Well designed control panel for easy machine control.

4. Spindle spindle with inverter engine. The operator can easily adjust the speed with in the control panel.

5. Super wheelhead with a bimetal shell bearing in its the structure gives the spindle high stiffness and stability.

6. Longitudinal the movement of the table is effected by a hydraulic cylinder. Table guides prosharenny manually.
