Construction

Head stock

8 different speeds possible. The headstock is all geared type, having splash lubrication. It houses the main spindle and the gears (for 8 different speed). The drive is taken from the motor, which is housed inside the left pedestal. And, the speed changeover levers are conveniently placed – to ensure quick setting of the required speed. The headstock is well seasoned and the gears are hardened and ground. what’s more the bed other castings are all made to ISI standards.

 

Feed gear box

Is provided with a feed gear box for cutting inch and metric series threads. Setting of the correct pitch is quick, and can be done easily by using the changelevers and knob. The gears however, are lubricated by a plunger pump driven by an eccentric pin and a cam. No gear charging is required.

 

Apron with oil bath

The apron design is of the ‘totally enclosed’ type and comprises an oil bath, in which the gears of the apron run. The half nut lever is interlocked with the feed lever so that only one can be operated when the other is not in use. And, both the sliding and the surfacing feed can be engaged by the friction clutch lever.

 

Rigid tail stock

It is robust in construction and is fitted on a separate vee guide on the bed; this ensures highly accurate alignment along the entire length of the tailstock. Further, It can be set over on either side, for turning small tapers. And, it is possible to clamp the tailstock casting along the bed by using a single levered cam type clamp.
