Machine tool refers to the machine of manufacturing machinery, can also be referred to as mother machine and tool room machine. General accuracy requirement is high and the surface roughness requirement is thinner part, are on the machine tool for processing, and processing methods in addition to cutting, casting, forging, welding, stamping, extrusion, etc. Thus it can be seen the machine tool is an indispensable part of mechanical manufacturing industry.
The machine tool has a lot of kinds, among them the common has the following kinds:
Turning machine, main is to use turning cutter to rotate the work piece turning processing machine tool. Drill, expanding drill, reamer, screw tap, threading die, etc. tools are available on a turning machine processing accordingly. It is mainly used for machining shaft, plate, cover and other work piece what has rotary surface, is the most widely used in machinery manufacturing and repair factory of machine tool.
Boring machine, main is to use boring cutter to artifacts existing prefabricated hole boring processing machine. Is mainly used for machining high precision holes or one-time positioning multiple what finished machining of holes. In a large box part processing equipment, boring machine is the most important.
Drilling machine, main use drill to process hole on the work piece is machine tool. Drilling machine structure is simple, the processing precision is relatively low, can drill a hole, blind hole. If want to enlarge hole, counter boring, reaming or tapping etc. processing. As long as replace special cutter can work.
Milling machine, main is to use milling cutter in the work piece on the processing of the every surface of the machine tool. It in addition to processing flat, grooved, various surface, gear, you can also process more complex type surface.
Planing machine, it is with the planing cutter to the work piece surface flat, grooved or forming surface planing machine tool. Can planing on planing machine horizontal, vertical, slant, curve, also can planing hole, gear and rack, etc. Planing machine is most suitable for planing narrow long surface of the work piece, but the productivity is low, only suitable for small and medium-sized batch production.
Grinding machine, is the use of grinding apparatus work piece surface of machine tool. Grinding machine for grinding the part with high precision and surface roughness is small, the hardness is high or relatively brittle material, grinding machine can be processed.
CNC machine tool, is short for computer numerical control machine tool, is a kind of program control system of automation machine tool. The operation and monitoring of the CNC machine tool are all completed in the CNC unit. Its machining precision is high, has the stable machining quality; A high degree of automation, which can reduce labor intensity.
Forging machine tool, it is for the use of metals and machinery cold manufacture equipment, and mainly to change the shape of the metal processing. Forging machine tool includes veneer reeling machine, plate shearing machine, punching machine, press machine, hydraulic machine, oil press machine, bending machine and so on.
