CNC centering lathe will generally be used in the bar type processing small parts, large batch, much is a molded parts. As long as it is involved in bar type processing, the diameter should not exceed 20mm, walking lathe with feeder his advantages (because the walking lathe must be equipped with a feeder to process), so that he is a small independent production line, whether it is the speed of processing, labor costs, he is advantageous. Walking machine of the material in motion, walking machine is the knife in motion in, CNC walking machine domestic previous old call should be longitudinal cutting lathe. Mainly used for bar material small parts, high-volume processing. Generally is the feeder will bar material from the spindle through the hole, spring collet automatic clamping. If the parts hanging elongation will need to match the tip. If the tail needs to be machined, it should be equipped with a second spindle. If you also need to process four and six drill holes and other points to be equipped with a power tool holder and spindle indexing. CNC centering machine is mainly limited by the diameter of the material, general zui large size centering lathe can only process parts with a diameter of 20 mm, as long as the centering machine can be processed parts, its machining accuracy, machining speed, go knife machine are difficult to compare! Advantageous features:
1, CNC walking center machine a clamping non-stop spindle can be turned more than 200mm length of the parts, if you are turning a 5mm length of the parts, walking knife walking center can be car, but walking center in one fell swoop can be turned out of 20 ~ 30 parts before the need to stop and feed! 2, CNC centering lathe cutting always in the material fixed in the nearest position, so the rigidity is very good, you think about your lathe after clamping the parts, the tool sticking to the clamping position of a few mm to turn, rigidity will be good to what extent. 3, CNC centrifugal machine are turning and milling one, a machining complexity of molding is also non-cutting machine comparable to the original old-fashioned automatic car, we commonly known as cam machine lathe. And now more advanced CNC automatic lathe, we call walking lathe or longitudinal cutting lathe. Mainly spindle Z forward and backward movement, and the knife can be X, Y movement, can realize three-dimensional processing, a molding. In the past, basically with imported, but the price is too high, and now the domestic also have their own mature technology.
Compared with conventional CNC machining process, composite machining has outstanding advantages mainly in the following areas.
(1) shorten the product manufacturing process chain, improve production efficiency. Milling and turning composite processing can be realized once the card to complete all or most of the machining process, thus greatly shortening the product manufacturing process chain. This on the one hand reduces the production of auxiliary time due to the change of loading card, but also reduces the manufacturing cycle of tooling fixtures and waiting time, can significantly improve production efficiency. (2) Reduce the number of clamping, improve machining accuracy. The reduction of the number of times of clamping avoids the accumulation of errors due to the transformation of the positioning reference. At the same time, most of the current mill-turn compound machining equipment has the function of online detection, which can realize the in-situ detection and precision control of the key data of the manufacturing process, thus improving the machining accuracy of the product. (3) Reduce floor space and production costs. Although the single unit price of turning and milling composite machining equipment is relatively high, the shortening of the manufacturing process chain and the reduction of the equipment required for the product, as well as the reduction of the number of jigs and fixtures, the workshop floor space and equipment maintenance costs, can effectively reduce the overall fixed asset investment, production operation and management costs.
