Why Choose Our CNC Solutions
Key Features
- ● High-Rigidity Structural Design: The machine bed adopts an integral four-guideway structure with a wide span, ensuring outstanding stiffness and resistance to deformation. The rectangular transverse guideway, combined with a frame-type tool carriage and fixed tool post, offers optimal rigidity—especially suited for over-center turning operations.
- ● Precision Spindle Assembly: Equipped with double-row short cylindrical roller bearings and adjustable radial clearance, the main spindle delivers high rigidity, smooth rotation, and consistent precision even under heavy-duty cutting of large-diameter rollers.
- ● Efficient Lubrication & Protection: A centralized lubrication system supplies metered oil directly to key guideways and movement interfaces. Stainless steel protective covers on both longitudinal and transverse axes preserve motion accuracy and reduce long-term maintenance needs.
- ● Digital Readout (DRO) Integration: The integrated high-resolution DRO system allows real-time monitoring and fine adjustment of axis movement, minimizing setup time and improving precision for both rough and finish turning tasks.
