Product Characteristics:
1. Adopt horizontal flat guide rail structure, resin sand casting, high rigidity, guide rail quenching and fine grinding, high precision, durability
2. Integral gear box type large aperture spindle unit, three supports, high rigidity structure, suitable for heavy cutting
3. Spindle frequency conversion or servo, can achieve constant linear speed turning
4. Headstock gear set and spindle of models 6150 and above are fine grinded to ensure low noise
5. 6163/6180 model, widen the guide rail, enhance the rigidity of the fuselage, improve the cutting strength
