China Precision Inclined Bed CNC Lathe Machine

The space in precision machining for small diameter parts and design, low cost of the lathe spindle motor adopts frequency conversion motor or FANUC servo motor, has the advantages of small volume, large stroke, high spindle speed, high feed accuracy, easy operation, easy maintenance, has the advantages of smooth chip removal. The achieved high precision CNC.CK-7520A series of small precision CNC lathe lathe successfully meets the small diameter high precision, high efficiency to automatic processing.
Main machine tool design features:
1.High precision spindle- The cartridge type spindle of lathe is supported by japan super precision bearings .The arrangement of 3 front bearings and 2 rear bearings ensure high rigidity and lasting accuracy of spindle .Spindle run out is less than <3μm.
2.Extra heavy cutting-Hydraulic combined with high speed and high accuracy combined with rigid and precise power chuck increase greatly heavy cutting and tough metal cutting capacity.
3.Control system-Driven by FANUC control systems that enable the lathes with great stability.
4.High efficiency machining-Max.speed of spindle is 5500rev/min, rapid traverse rate of X and Z axes is up to 18m/min .Auto parts feeder can be equipped to fulfill fast and efficient automation production.
5.Comb type tool rest-The unique design of comb type tool rest gives minimumrepeatability error during tool change ,it is fast.Precise and considerably time saving.
6.Accurate feeding-Each feeding axis is driven by servo motors through japan NSK,THK precision ball screws,machining accuracy is ensured and long time accuracy is remained .repeatability is less than < 1μm.
7.Machine bed construction-High rigidity meehanite cast iron 60° slant bed,easy chip removal,compact design ,beautiful appearance.
