SLIDES over the bed-ways between the headstock and the tailstock.It provides various movements for the cutting tool MANUALLY as well as by power feed.The carriage can be locked on the bed at any desired position by tightening the carriage lock screw.The carriage consists of the following parts:Saddle: It is an 'H' shaped casting having 'V' guide grooves at the bottom face, corresponding to the lathe bed-ways for MOUNTING on the lathe bed and for sliding.Cross Slide: The cross-slide is mounted on the top of the saddle, and it provides cross-movement for the tool. This is fitted at right angles to the bed and is moved by means of a screwed spindle, fitted with a handle.Compound REST: The compound rest is fitted on the top and to the front of the cross-slide. The tools are fixed in the compound rest, so it is called a tool rest also. The compound rest can be swiveled horizontally through 360°.Apron: The apron is bolted to the front of the saddle. It contains a mechanism for moving and controlling the carriage.Tool Post: The tool post holds the tool meant for the operation to be performed on the work. The tool post is assembled to the top slide.The tool is provided with the following three movements by the carriage.Longitudinal feed – with the help of the carriage movement (parallel to the axis of work i.e Horizontal axis)Cross feed – with the help of the cross-slide movement (perpendicular to the axis of the work)Angular feed – With the help of the compound slide movement POSITIONED at an angle to the axis of the work.
