Designed for demanding applications, this machine integrates a high-performance cartridge spindle. Built with premium imported bearings in a "three-front, two-rear" arrangement and powered directly by a servo motor, it delivers exceptional precision, rigidity, and rotational stability.
Its foundation is a robust 45-degree slant bed made of high-grade cast iron via resin sand molding. The densely ribbed structure provides superior stiffness and effective vibration absorption, while also facilitating easy operation and efficient chip flow.
For rapid and accurate axis movement, the X and Z axes employ high-rigidity linear guides and precision ball screws. These are directly driven by servo motors through flexible couplings, with a central lubrication system servicing all guideways and screws. This design achieves high positioning accuracy, minimizes thermal effects, and enables fast traverse speeds of up to 30 m/min.
A versatile T-type gang tool post allows for multiple tool arrangements and enables very quick tool changes.
The hydraulic power unit incorporates a variable displacement pump, motor, and solenoid valves. Its integrated air-cooling system maintains low operating noise and stable, cool oil temperatures.
Completing the package is a streamlined, fully enclosed guard with excellent sealing. The smooth-sliding door ensures easy access and is fitted with a safety interlock for operator protection.
