7640 drilling and milling machine, drilling and milling machining center-changzhou erji tool co., ltd.

● the main basic parts are made of resin sand, with secondary aging treatment, special box-shaped structure and optimized arrangement of reinforcing ribs, so that the machine tool has good rigidity and shock absorption ability.

● the three-axis feed is driven by precision ball screws, and is matched with plastic-coated and hardened guide rails. it has the characteristics of good wear resistance, low friction and high rigidity.

● "guangshu" gsk980mdi control system (huazhong cnc hnc-808di control system), x, y, z three-axis servo motor, spindle servo motor, can realize three-axis linkage processing. it has the functions of drilling, milling, boring and tapping.

● lcd chinese menu, man-machine dialogue programming, easy to operate.

● the automatic centralized lubrication method is adopted, and each lubrication point (such as guide rail, ball screw, etc.) is regularly and quantitatively lubricated to ensure good lubrication of important parts.

● the main shaft drive adopts precision gears with pneumatic high and low gears to ensure that it meets the requirements of strong cutting. the low-speed cutting torque is large, and it can be used for strong cutting.

● special configuration: fully enclosed protection/manual chip collector (or chain plate type chip conveyor), internal cooling spindle (central high pressure water outlet) ---- special order, available at another price.
