Machine Bed

Close grained Graded casting (GR 25) having Box structured adequately Ribbed design,provides very  high Rigidity and thermal stability in long Run.

Work Head

The machine has Rigid Universal Work Head.It has an alloy steel Spindle running in unique Hydrodynamic Bearings having self-alignment of clearance for different speeds.During Dead center grinding a simple adjustment  completely eliminates the clearance in the bearing thus providing rigid support to the jobs. The bearing arrangement gives wear free operation.

Wheel Head

The wheel head has a very rigid Spindle running in Hydrodynamic  Multi-point Bearings . The Spindle  is made of alloy steel, specially heat treated to achieve high accuracy and stability for long life, Spindle cartridge unit is easily interchangeable.

In-feed System

The infeed system moves on pre-loaded Linear Guideways. This guarantees high repetitive accuracy and stick-slip free fine movement of the slide. Infeed is give throughs an hardened and precision ground cam.Grinding allowance and the required steplessly versions.The automatic grinding cycle operates as follows.

Rapid Approach-Coarse Feed-Fine Feed-Spark Off-Rapid Retraction of the Wheel Head the Infeed Hand Wheel to the pre-Selected Position.

This cycle also starts/stops the work head motor and the coolant motor automatically.The machine is also capable of interfacing with in process gauging unites as options.

Lubrication

The infeed slide is grease-packed for life.The table slide with Turcite is provided with automatic lubrication from Hydraulic system.

Coolant Systems

Variety of coolant filtration systems are available.From Baffle tray (standard) to magnetic,paper cum magnetic type filtration system as optional.

“S” Models with Hydraulic Rapid Table movement & Manual infeed also available.
