MK215 cnc inner hole grinderMachine overview
X,Z axis layout ( X axis is work piece clamping axis, do feeding motion, Z axis is grinding wheel axis, do reciprocating motion)
Cooling system: ① water cooling tube ② spindle cooling water tank with AC function ③fixture center flashing water to cooling the work piece hole, as follow picture:
There are special fixture:① centerless fixture ② thin film fixture ③ Barrel clamp (Fixture is controlled by hydraulic power, there’s a foot swith to control easily)
Grinding wheel dressing ( Usually we use diamond pen, it’s cheaper,but vulnerable, diamond wheel is durable, but a little expensive than diamond pen, the follow picture contains two kinds of dressers, it’s customized for our clients ( two grinding spindles).
Cooling water tank & Hydraulic station layout
NC system operation ( Usually we adopts Siemens 828D, the screen language can change into English, Operator only needs to proofread the tool position by hand held purse and enter the corresponding parameter column, then automatically cycle -- automatically grinding, automatically dressing) Screen as follow:
