Like compound slide, it also has degree graduations.

So, the cross slide is free from the slide screw. In order to connect the cross slide, the binder screw should be removed. The guide block connects the rear end of the crossing slide and helps to move. With the help of a guide block, it moves on the guide bar. The guiding bar also functions as its center while performing the operation. This bar has the ability to swing, hence provide flexibility in angle. For your desired turning angle, a guiding bar is used here. The workpiece attaches to the rear end of the lathe bed. The bottom bracket or tray is to be used for this attachment. Job attachment is a little bit different here.
Here are a few key tips for you if you are using the compound slide method. While the tool travels, following the path of the compound slide, you get your required tapper. By turning the screw, you can give feed along the desire path and angle. The tool post is used for setting the cutting tool. Because you can adjust your desirable angle by loosening the nuts.Īnd the other is, the job axis rotates in parallel to the axis of the lathe bed. One is that it’s cutting tool moves just the way you want to. The compound slide has two basic principles. You can perform taper turning on both outsides of the workpiece or in the bore. The flexibility of the compound slide can rotate on its central pins in both directions because it is fixed on the top of the cross slide. Before clamping, the compound rest should be swiveled to the desired angle. The job rotates along with the lathe axis. Like any other lathe operation, the workpiece is set in the chuck with clamps in this method. To produce a short and steep taper, the compound slide method is the suggested method.

How to set a parallel position? These are the steps: Once the turning operation is done, utmost care should be given to set back the tailstock. Instead of degrees, the basis value of the tailstock is offset in mm or inches.Īs the work is mainly at an angle, it should be done between centers. The tool moves in a parallel position with the machine bed. In this method, the machine bed axis is set with an angle where the axis of the job rotates. The lead screw with accurate threads is to be used only for thread cutting & can be engaged or disengaged with a handle provided on the gear box while the other handle is for obtaining the desired three speeds.When there is no available taper attachment, this method is used then. Three Speed Gear Box : The Three speed gear box is provided with the lathe to obtain coarse, medium and fine cutting ranges, both long and cross on the feed bar through gears. It has long bearing within the barrel and ensures true alignment. Tail Stock : The tailstock is designed to give maximum strength bolt operation. All gears are of steel and are well tempered. Tool Post : The Toll-Post is made out of one piece steel block and can hold four different tolls at a time and can be swivelled to any desired angle.Īpron: The apron gives movement to the saddle for screw cutting sliding and surfacing by means of enclosed gears and half nut. It is assembled with cross and upper slide graduated to give desired angles. The saddle is fitted with 'Hand' and 'Automatic' transfers along the bed with steel rack and Pinion. Saddle : The 'V ways running on the bed and the slides are most accurately hand scrapped and aligned accurately with the bed and the headstock. Head Stock gears are of "Clutch system" of high production in small machines & "Kirloskar system" in large machines.
The spindle is the best steel with a finish to give accurate results. (a) Parallel Brass with thrust Bearing, (b) Conical Brass, (c) Taper Roller Bearing.
The bearings are of the following three types: Head Stock : The head-stock is of top quality castings providing support to the spindle bearings. It has cross-ribs to support its walls and three inverted 'VEES' assembled with a removable gap for large swing. AMI lathes are guaranteed for their original design, and are tested to the graded limits with specially imported precision tools.īed: The bed being the foundation of the lathes is carefully designed and is of high grade cast iron. Design & Workmanship : AMI lathe machines have been designed to cater need of sustained accuracy and superb finishing.
