旋转导套一般用来加工细长轴类零件,他的导套和主轴为同步旋转状态,保证了工件的同轴度和直线度比较高,但相对应的尾料长度也增加工了回转导套的长度,旋转导套在车削倍径比较大的工件时有明显的优势。
Go through the processing lathe rod material processing into small parts, batch, a lot of parts are once formed. As long as it involves rod processing,
Within 42mm in diameter, wuxi machine processing with automatic feeder can obtain a huge advantage, the machine with automatic feeder, is a small independent
Production line, regardless of processing speed, labor cost, have a huge advantage. The main difference between the processing and the cutting machine is: the material of the cutting machine is moving, the cutting machine is moving, the cutting machine is also known as the longitudinal cutting lathe, turning and milling compound
Lathe, Swiss lathe. Mainly used for holding small parts, mass processing. Generally, the feeder will pass through the hole through the spindle, spring chuck automatic clamping
Tight. If the parts of the elongation need to match the long material support or use double spindle go, use the back shaft support. If the tail needs to be processed
And then you have to have a second principal axis. Take the advantage of the huge advantage is to support square, hexagonal and other heterosexual raw materials bar, and the spindle has the function of indexing positioning
The central machine is mainly limited by the diameter of the material, the general size of the central lathe can only process the diameter of 42 mm parts, the current domestic support
As long as it can be processed parts, wuxi go to go to machining precision, processing speed, knife machine are difficult to compare!
The main advantages are as follows:
1, a clamping stop spindle can turn the length of more than 200mm parts, if you are a car a 5mm length
Parts, go knife go heart can car, but go heart at a stretch can car out 20 to 30 parts need to stop feeding
2, the center of the lathe cutting always in the material fixed near the position, so the rigidity is very good, you think about your lathe clamping parts,
The cutter sticks to the clamping position a few mm to turn, the rigidity will be good to what degree.
3, go away are turning milling body, a processing molding complexity is not a knife machine than the original automatic car, we commonly known as CAM
The engine bed. But now more advanced CNC automatic lathe, we call the center lathe or longitudinal lathe. The main axis Z moves forward and backward while the knife
X, Y can be moved, can achieve three-dimensional processing, forming.
So, what are the forms of the guide sleeve? The guide sleeve of the machine is generally divided into three types: non-guide sleeve, fixed guide sleeve and rotating guide sleeve. The following is a brief description of the differences in the processing of the three forms of guide sleeve:
No guide bush's biggest advantage is to reduce the length of the tail material, generally go heart tailing are above 180 mm length, coupled with the workpiece material waste is serious, no guide bush good solve the problem, to his tail material feeding machine, at around 10 mm, reduce the cost of materials, but no guide sleeve is only suitable for overhanging not long product;
Fixed guide sleeve in the processing of parts only play a supporting role to the bar, it is not rotating in the processing, the length of a processing with the stroke of the axis Z is the same, the bar straightness requirements are higher, such as the bar straightness is poor, easy to cause damage to the fixed guide sleeve;
Rotating guide sleeve is generally used to process slender shaft parts, its guide sleeve and spindle for synchronous rotation state, to ensure the workpiece coaxiality and straightness is relatively high, but the corresponding length of tail material also increased the length of the rotary guide sleeve, rotating guide sleeve in turning the workpiece with a larger diameter has obvious advantages.
