CK8470*2500 CNC Heavy duty Roll Turning lathe suitable for roughing and finishing section mill rolls with profiles of the cast iron roll or high speed steel or tungsten carbide roll etc.
The CK8470*2500 CNC heavy duty roll turning lathe are suitable for workpiece up to the following data:
Max. Diameter to be machining : 700mm
Max. center distance:2500mm
Max roll weigh on center:8000Kg
CNC controller: siemens 828D
Optional function 1
Special software for programming shop turn machining step programming.
Optional function 2
The turret block can be selected with the NC quartet turret. It can fix 4 shanks at the same time. it’s very good for machining rough and finish with different shanks.
Description:
The workpiece are accommodated between the 4-jar faceplate of the headstock and the center of the tailstock.
The CK8470*2500 CNC heavy duty turning lathe are the series of 5-bedways turning lathes has been especially designed for rolling cylinder maintenance. The CK8470*2500 CNC heavy duty turning lathes are strong and reliable, with superior rigidity given by the oversized components and 5 guideways design. There are 2 guideways for the tailstock, 2 guideways for the saddle in the level surface, at the same time there have 1 guideway on the vertical surface link to the end of the saddle beside the operation side.
The CK8470*2500 CNC heavy duty roll turning lathe are suitable for all kind of pass shape
