This series of lathe machine beds is a whole box-shaped three guide-way structure, adopting high standard cast iron (HT300) one molding casting, after the second aging treatment, it has the feature of stable performance; guide-way width (1600mm), good rigidity, anti-vibration ability, The main mechanism is driven by the 75KW DC motor, using the method of adjustable magnetic regulation, adjustment voltage and hybrid speed regulating mode, the ratio is 1: 22. Speed change is three-step, mechanical and electrical integrated speed ratio is 1: 200, spindle speed range is 0.8 ~ 160r / min and step-less speed change. The spindle bore diameter is large, the headstock adopts the split-type structure, and the contact rigidity is improved after scraping. The spindle adopts the front and rear bearing structure so that the radial and axial stiffness and rotation precision are high. The tailstock is composed of the upper and lower body, the upper body is equipped with a sleeve, a spindle, and a pressure sensor, and the lower body is equipped with a fast-moving mechanism. CK61100 with Ф1600mm heavy-duty manual four-jaw chuck; CK61200 with Ф1800mm heavy-duty manual four-jaw chuck; CK61200 with Ф2000mm heavy manual four-jaw chuck. The standard configuration has two steady rests, one is closed type, and the other is open type. It is equipped with a protective device and an emergency stop safety button, when the machine suddenly encountered a sudden power failure or other failures, due to the special design of the control circuit, it can be self-protection to ensure the lathe machine and personnel safety.
This series of lathe machines is based on the international market and the latest development trend of CNC lathes developed with semi-closed-loop control of the popular CNC heavy-duty lathes. 1600mm wide flatbed guideway provided users with a larger workpiece load, it is the production of large parts ideal mechanical processing equipment.
