It consists of the saddle, cross slide, compound rest, top slide or tool post and the apron. Metalworking lathes have a carriage (comprising a saddle and apron) topped with a cross-slide, which is a flat piece that sits crosswise on the bed and can be cranked at right angles to the bed. The main function of the carriage is to position the tool along the lathe bed. Lathe bed is made of high grade special cast iron having high vibration damping qualities. The feeding is done by the carriage and the depth of cut is provided by the cross slide. Compound rest – the compound rest supports the tool post and cutting tool in different positions. Carriage contains some other parts . Feed rod – a feed rod is used to transfer the carriage from the left side to the right side and from right size to left size. The bed should be rigid enough in order to prevent deflection and must be able to resist the operations. The carriage even rests over the bed and slides over it. it firmly holds the workpiece that the force from the cutting tool can’t overpower. The main parts of the lathe are: The carriage even rests over the bed and slides over it. Spindle Clutch Lever Main spindle 14. Carriage 5. It is used to hold various tools and it of three types.

Cross-slide 7. Headstock 2. Carriage Handwheel: The carriage handwheel is used to manually position and/or hand feed the carriage in the longitudinal or Z axis. Top surface of bed is machined accurately. Has a keyway, with two reversing pinion gears, either of which can be meshed with the mating bevel gear to forward or reverse the carriage using levers. During the travel of the lathe, the work piece is rotated against the tool to achieve material removal and the direction of tool movement becomes feed. It also performs great when carrying out operations like drilling, reaming, tapping etc. It is of two types known as 3 jaw or self-centering chuck and 4 jaw or independent chuck. For taper turning and facing cross feed is used for conventional turning carriage provides longitudinal feed. Tool post Carriage: The carriage houses the saddle, the cross slide, and the apron.

The lathe bed forms the base of the machine, the headstock and tailstock are located at either end of the bed and the carriage rests over the lathe bed and slides over it. This problem contains three parts. Disadvantages – the lead screw, and the half nuts take extra wear and the fact that SOME lathes that have separate feed screws and lead screws allow you to set the rates separately, and almost ALL have the feed screw running much more slowly, so even if you have the lathe set for a fairly coarse thread, the feed screw is in a “somewhat useful” range. There is no power feed to the compound slide and it is hand operated. Chuck – the chuck securely holds the workpiece as it res toward the cutting tools. Main spindle – this spindle has a hollow cylindrical shaft, which allows long workpiece to pass through it. It runs through the outer ways. During the travel of the lathe, the workpiece is rotated against the tool to achieve material removal and the direction of the tool movement becomes feed. It plays a perform role as it converts rotational motion to linear motion. I’m really inspired along with your writing abilities and also with the format to your blog. 12.2). The main function of the lathe is to remove the material from the work piece and make the work piece the desired shape and size. There were other modifications of the lathe machine that were developed in different time periods. Required fields are marked *. The compound slide handle is also equipped with a micrometer dial to assist in determining the depth of the cut. What function does a lathe carriage have? This is accomplished by holding the work securely and rigidly on the machine and then turning it against … "BG" -BackGeared for slow speeds (see below) "BGSC" - BackGeared and screwcutting BED The bed of the lathe provides the foundation for the whole machine and holds the headstock, tailstock and carriage in alignment. Cross-slide – this part is mounted on the top of the saddle and its features a t-slot. Excess metal is removed as chips.
