Silent Features
- THE BED is made of close-grained cast iron, having unusual
strength and long wearing qualities. It is machined and ground to
fine finish and is well braced to withstand vibration free operation
even under heavy cutting load.
- HEAD STOCK The flat seat of headstock over the bed is perfectly
matched by precision hand scrapping. The hollow spindle runs in a
pair of amply dimensioned split gunmetai adjustable bearing and one
Thrust Ball Bearing or Heavy duty Taper Roller Bearings.
- THE APRON is of double wall designed with independent driven
motion for feeds and screws cutting. Simultaneous
- Engagement of feed and screw cutting is prevented by an interlock
mechanism.
- THE TAILSTOCK is of special and sturdy design. Inverted “V”
guides it and flat ways of the bed independent of the saddle guides
and has an offsetting drive for taper turning. The body including
the base can be clamped to the bed by means of bolt and nut
provided.
- STANDARD Back Plate for Dog Chuck, Dead Centre (hardened and
ground), Centre EQUIPMENT Sleeve Traveling and Fixed Steady Rests.
One set of 22-machine cut Change Gear wheels, Oil Tray, Motor drive
arrangements and Thread Dial Gauge.
