Name: Heavy Turning Center
Brand: Qunzhi
SKU: 234043262

The main unit structure is optimized through structural analysis, and the dynamic rigidity of the bed is maintained during heavy cutting by reducing the height of the equipment;
The 45-degree tilted bed greatly improves its processing stability and accuracy maintenance;
The spindle motor specifications are enlarged, the power and torque are increased, and the heavy cutting capability is greatly improved.
The strong structure lathe is made of one-piece high-strength HT300 cast iron, and the sliding plate is covered with special wear-resistant sheets, which are precision-fitted by manual scraping. The bearing seat and motor base are all scraped and inlaid assembled;
The box-type guide rail has a strong ability to offset the vibration caused by cutting, reduce tool loss, and improve processing stability;
