The space in precision machining for small diameter parts and disc parts and design, low cost lathe, spindle motor using 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. Make it a real high the precision CNC lathe is successful.
Main machine tool design features:
1.High rigid structure in small area:45° STN50 CNC lathe adopts the advanced hybrid slant bed structure to keep in with excellent rigidity and precision machine tool performance under the premise of the smallest area was realized .Through the rest of a merger with the sliding body ,increase the bed saddle guide means such as span improved the overall structure of the machine tool rigidity.
2.Dense baking quality of cast iron castings:Base and sliding saddle structure are of high quality dense baking cast iron castings ,more make the machine has good rigidity and precision performance ,laid a solid foundation for high speed and high precision processing.
3.High rigidity high precision of the spindle design can easily implement strong heavy cutting:STN50 spindle of CNC lathe design principle of high speed ,overload,high precision,the swiss company＇s patented technology manufacturing that has able easily implement strong heavy cutting .In spindle parts assembly ,main shaft bearing pre-tightening force using specialized equipment and tooling and ensure the measuring instrument ,spindle assembly good rigidity ,high precision,long life;In front bearing and balancing the bearings after processing ,make the main shaft of dynamic balance is more accurate,can fully meet the demand for high speed machining all kinds of occasions.
4. Servo tailstock:STN50 series servo tailstock of nc lathe can be configured,the tailstock directly driven by servo motor ,the tailstock stroke and tailstock thrust can be arbitrarily set in the program ,the servo tailstock in axial parts without theuse of humanization process in unique occasion.
5.Rapidly indexing high rigidity turret:STN50 CNC lathe cutter adopts servo degree and tooth plate positioning structure ,not only has good rigidity ,but also has the very high indexing speed.Turret motion and coordinate indexing action movement at the same time will improve the efficiency of the machine tool further.
