| SALIENT FEATURES |
| MACHINE BED |
 |
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 GUIDEWAYS |
|
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 parts. |
| WORK HEAD |
|
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 |
|
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 |
|
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 |
|
Tailstock is of single piece construction for maximum rigidity. |
|
Hydraulic 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. |
| DWELL |
|
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. |
| HYDRAULICS |
|
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. |
| ELECTRICALS |
|
Electrical/Electronic controls are contained in separate control cabinet, outside the machine, making it proof and provide easy |
| |
maintenance. |
| OPTIONAL |
|
Stepless variable workspeed, 200 mm centre height in lieu of 150 mm & Inprocess Guage. |
