Packing Information

High Quality

Left and right tool holders of DVT52 series are controlled by DVT system and equipped with digital display scale.

High Efficiency

The table can bear large tonnage load with good stability, high efficiency, safety and reliability.

High Performance

Its excellent structural performance and strong rigidity can meet the requirement of strong cutting.

Implement the latest national precision standard and safety standard, equipped with advanced and reliable electro- mechanical components at home and abroad.

Servo drive and X.Z axis feed servo motor are adopted from Beijing Super Synchronous products.

The X and Z axes of the left and right tool holders are driven by servo motor through precision planetary reducer to increase the torque to drive the ball screw for horizontal and vertical movements.
