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 manual 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 device 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.
