Turn milling compound CNC machine tools
Turning and milling compound CNC machine tool is a machine tool that can complete turning and milling, and can be a lathe and a milling machine. Turning mill compound machine was first used to process propeller, mainly to avoid 2 clamping brought by the loss of precision and datum loss!
CNC turning and milling compound machine tool is a compound processing machine tool of a main model, in addition to the function of CNC lathe can also complete plane milling, drilling, tapping, straight groove, spiral groove and milling teeth, with turning, milling and boring and other complex functions, can achieve a clamping, complete the processing concept.
It is one of the most rapidly developing processing methods in recent years
General turn-milling compound machine tool has the following two characteristics:
1, the spindle motor adopts servo motor, the spindle rotation movement and feed movement can be linked.
2. In addition to configuring the turret tool rest of CNC lathes, at least configure power tools, or configure independent power tool rest
Compared with ordinary vehicles, turn-milling compound has the following advantages:
CNC milling complex center can install a variety of special tools, new tool layout, reduce tool change time, improve processing efficiency, can achieve a clamping to complete all or most of the processing process, thus greatly shortening the product manufacturing process chain.
Turning milling process, the tool for intermittent cutting, for any material forming workpiece can be shorter cutting, easy to automatic chip removal. And intermittent chip can make the knife has sufficient time cooling, reduce the thermal deformation of the workpiece, but also can improve the service life of the tool. Compared with the traditional CNC machine tools, turning milling processing speed is higher, cutting product quality is better, and reduce the cutting force, improve the precision of thin-wall rod and slender rod, workpiece forming quality is high.
Because the cutting speed can be decomposed into the rotation speed of the workpiece and the rotary speed of the tool, according to the mechanical characteristics, can improve the rotary speed of the tool, reduce the rotation speed of the workpiece can also achieve the same processing effect, this feature is particularly effective for large forging blank processing, Because the reduction of the forging blank speed can eliminate the workpiece eccentricity caused by vibration or radial cutting force of the periodic change, so as to ensure the smooth cutting of the workpiece, reduce the workpiece processing errors.
The low rotating speed of the workpiece can effectively reduce the centrifugal force of the workpiece, avoid the deformation of the workpiece, and improve the machining accuracy of the parts. Turning milling processing using large longitudinal feed can also get accurate cutting, surface roughness can also be effectively guaranteed, turning milling complex machine tool can use turning, milling, drilling, boring and other different methods to achieve the processing of the workpiece, the workpiece can also be a clamping and complete multi-faceted processing tasks, to ensure processing accuracy.
The reduction of loading times avoids the error accumulation caused by the transformation of positioning datum. At the same time, most of the current turn-milling compound processing equipment has the function of online detection, which can realize the in-position detection and precision control of the key data in the manufacturing process, so as to improve the machining accuracy of products. The high strength integrated bed design improves the gravity machining capability of hard cutting materials
