The table, headstock, machine base, and carriage are all made of high strength FC-30~FC-35 castings. The guideways are constantly being lubricated by a hydrodynamic hydrostatic lubrication system to reduce drag between components and improve part finish.
The wheelhead spindle is designed with hydrodynamic bearing and is made of Ni-CR-Mo alloy for superior strength and maximum grinding finish.
The wheelhead and carriage are lubricated by a hydrodynamic hydrostatic lubrication system. The spindle and spindle motor utilize an indirect design to avoid strain on the motor.
The FANUC CNC-controller is used to develop the roll grinding process automatically. The system is configured with a humanized operation panel for the user which makes the grinding operation easy and precise. All the operator need to do is call a cutting program from memory to perform the grinding sequentially.
Crown grinding is also easy which include base arc curve SINE curve COSINE curve CVC curve and combined arc curve. The camber values is assigned by the program. The system has integrated a net function for output & input of the data for the cutting & the parameters of the machine and maintenance.
Tailstock re-positioning is made easy with the use of an air assist devise mounted on the bottom of the tailstock.
Work piece alignment is done via tailstock adjustment. The diamond wheel dresser is mounted on side of the tailstock for easy access. An optional revolving 4-jaw chuck tailstock is available for extremely heavy work pieces.
