A very useful and indispensable specialty is the straight-axle turning-lathe. Fig. 212. The peculiarity of the design is this:—The headstock is in the centre of the bed, and the shaft passes through it, and is driven by it, being centred on two movable poppets situated at the ends of the bed. The headstock is treble-geared. There are two slide-rests, so that both ends of the axle are being turned at the same time. Each saddle is fitted with two sets of compound slide-rests, the front set having independent adjustment to the tool-slide. There are two screws in each saddle, and both rests can be actuated independently from the front of the lathe. Each saddle has a guide-screw, with independent automatic feed, and quick adjustment on the bed by rack and pinion. The lathe is made in two sizes, 12-in. and 10-in. centres, to admit 8-ft, 3-in. between centres. The 12-in. lathe has a 1-2-in. hole through the headstock, and the 10-in. lathe a 10-in. hole. One of the sliding-poppets can be swung completely clear of the line of centres, to afford facility for getting the work in and out of the lathe. The lathe illustrated is by Sharp, Stewart & Co., Limited, of Glasgow. |
