CNC machine tools usually by the control system, servo systems, testing systems, mechanical transmission systems and other auxiliary systems.
1, the control system for CNC machine tool operation, management and control, through the input medium to get the data, the interpretation of these data and computing and the role of the machine;
2, the servo system in accordance with the instructions of the control system to drive the machine, so that the implementation of CNC tool and parts of the movement code;
3, the detection system is used to detect the implementation of machine tools (table, turntable, slide, etc.) displacement and speed changes, and test results back to the input, and input instructions are compared, adjust the machine movement according to their differences;
4, the machine tool drive system is to feed the servo drive components to the machine between the implementation of the mechanical feed drive device;
5, a wide range of auxiliary systems, such as: fixed cycle (to carry out a variety of repeated processing), automatic tool change (exchange specified cutter), transmission gap compensation mechanical transmission system gap error) and so on.

The main purpose of common machine tools


lathe Mainly used for processing a variety of rotating surface and the end of the body rotation. Such as turning inside and outside the cylindrical surface, conical surface, ring groove and forming the rotating surface, turning the end face and a variety of commonly used thread, with a variety of special equipment can also be processed surface. In the lathe can do drilling, reaming, reaming, knurling and so on.
Milling machines A wide range of machine tools, milling machine can be processed in the plane (horizontal, vertical), groove (keyway, T-slot, dovetail slot, etc.), gear parts (gears, spline shaft, sprocket well Surface (screw, spiral groove) and a variety of surface. In addition, can also be used for the surface of the rotor, the hole processing and cutting work, etc .. Milling machine at work, the workpiece mounted on the table or sub-first grade accessories, milling The main movement of the knife, combined with the table or milling head of the feed movement, the workpiece can be obtained for the processing surface.
slotting machine
Mainly used for processing a variety of plane (such as horizontal, vertical and inclined surface and a variety of grooves, such as T-slot, dovetail groove, V-shaped groove, etc.), linear molding surface. If equipped with profiling device, but also processing space surface, such as turbine impeller, spiral groove and so on. This type of machine tool structure is simple, not cutting back, so the lower productivity, generally used for single-piece small batch production.
Boring machine It is suitable for surface milling and hole machining of single or small batch production in machining workshop. The end of headstock is designed with radial turret for accurate boring of large hole and plane. In addition, drilling, reaming and thread processing.
grinder Abrasive grinding tools (wheel, belt, Whetstone or abrasive, etc.) as a tool for machining the surface of the machine tool, collectively referred to as grinding. Grinding machine can process a variety of surfaces, such as internal and external cylindrical and conical surface, plane, gear tooth surface, spiral surface and a variety of molding surface, etc., can also be sharpening tools and cutting, a wide range of processes. As the grinding process is easy to get high machining accuracy and good surface quality, so the grinding machine is mainly used in finishing parts, especially hardened steel and high hardness special materials finishing.
Drilling machine Widely used versatile machine tools, parts can be drilling, reaming, reaming, countersink and tapping the plane processing. In the radial drilling machine equipped with technology and equipment, can also be boring; bench drill coupled with the universal work table (MDT-180 type), but also milling keyway.
Gear cutting machine tools Gear is the most commonly used transmission parts, straight teeth, helical and herringbone gear cylindrical gears, straight teeth and arc teeth of the bevel gear, worm gear and non-circular gears. Machining gear tooth surface of the machine called the gear machine tool.
