They usually have an included angle of 60°, but in heavy machining situations an angle of 75° is used. Thanks for the A2A, Naomi! If a separate table is not available, use a wide board with a cleat on each side to lay on the ways. When the jaws are tightened up they will be pushing inwards on the plug. The lathe makes parts by spinning the part and having a cutting tool take material off of the diameter of the stock. Methods of manufacturing and product design have driven change for thousands of years. You may be thinking, “But […], Die Casting is the injection of molten metal into a Die (similar to a Mould) under pressure to create complex parts out of metal. Metal turning lathe hazards. A lathe can be used to create a smooth, flat, face very accurately perpendicular to the axis of a cylindrical part. Lathes are critical pieces of machinery, and they are used everyday here in our workshop. Never lay tools directly on the lathe ways. The simplest method is to fit a round piece of material in the chuck. It performs the same function as an ordinary center punch but without the need for a hammer.When pressed against the workpiece, it stores energy in a spring, eventually releasing it as an impulse that drives the punch, producing the dimple.
