• The machine bed is of one piece, close grained, graded cast iron.
• Box structure design, heavily reinforced with ribs, provides high rigidity and stability.
• Machine guide ways of V-Flat construction are precisely hand scrapped.
• The work head table as well as grinding wheel head slideways are coated with “TURCITE-B” linear bearing material which gives stick slip free movements, excellent
vibration damping and high repetitive positioning accuracy.
• Continuous automatic lubrication system provided for guide ways. Centralized lubrication system is also provided, for efficient and positive lubrication of other moving
• The machine has a rigid Universal Work head, which can be swiveled to facilitate taper grinding.
• Work head spindle can be locked for grinding between centers or it can be rotated with the driving plate to carry work holding fixtures like collet, face plate or chuck.
• Wheel head spindle is made of special alloy steel, specially heart treated, ground and lapped to achieve high dimensional stability and long life.
• Spindle runs in precision White metal bush bearings, which give very high accuracy and excellent surface finish to the work piece.
• Infeed system comprises of hardened and ground feed screw, which ensures high positioning accuracy and repeatability.
• Specially designed nut having backlash adjustment is provided.
• Automatic infeed at table reversal.
• Hydraulically operated Rapid approach / Retraction of wheel head slide.
• Tailstock is of single piece construction for maximum rigidity.
• zHydraulic actuation of Tailstock can be offered as optional.
AUTOMATIC GRINDING CYCLE (Optional)
• Single lever operated Automatic Plunge and Traverse grinding cycles.
• Cycle operates as Work head & coolant ON-Rapid approach-Auto feed-Spark off-Rapid retraction and infeed hand wheel to starting position-Work head & Coolant OFF.
• Amount of infeed, infeed rate and spark off time are adjustable.s
• Electronic dwelling arrangement provided for effective End grinding operations. Separate timers for left and right ends.
INTERNAL GRINDING ATTACHEMENT (Optional)
• Internal grinding attachment with its independent drive motor is hinged on the wheel head and can be quickly lowered into grinding position.
• Variety of Internal Grinding spindles can be offered.
• Hydraulic power pack with solenoid valves is housed outside the machine.
• Extremely good thermal stability is achieved in the machine by isolating the hydraulic unit.
• Electrical/Electronic controls are contained in separate control cabinet, outside the machine, making it proof and provide easy maintenance.
• Stepless variable workspeed, 200 mm centre height in lieu of 150 mm & Inprocess Guage.
