Lathe machining a part, there are two processing forms: one is the turning fixed, unformed workpiece machining rotation, and the other is to work fixing, by high-speed rotation of the workpiece, turning ( toolholder) horizontal and vertical movement carried out precision machining. Lathe can also be used drills, reamers, make the appropriate processing reamers, taps, dies and knurling tools. Lathe is mainly used for machining shaft, plates, sleeves and other artifacts have rotating surface, the machinery manufacturing and repair facility in the most widely used class of machining.
The material is often used as a lathe cutting of steel and copper, steel cutting sulfur S and phosphorus P high of material, sulfur and manganese is present in the form of manganese sulfide in the steel, and manganese sulfide in modern lathe processing of materials commonly used in aluminum alloy material, the density of the aluminum alloy material with greatly reduced the density of iron and steel materials, and low lathe difficulty, plasticity, greatly reducing the weight of the product, but also greatly shortened the time lathe parts followed by cost reduction has become the darling makes aluminum parts in the field of aviation.
