Basic knowledge of CNC lathes and their advantages and disadvantages
1.Product Description
The machine table automatic lathe can complete complex processing such as turning, milling, drilling, boring, tapping, engraving, etc. at the same time. Its processing efficiency and precision are much higher than those of traditional CNC machine tools. The high-precision feed system ensures the high rigidity of the CNC lathe.
The machine table automatic lathe is equipped with a spindle oil cooling system and adopts high-end motors. The cooling oil can cooperate with the spindle to form an oil cooling circuit to ensure that the machine table automatic lathe can run stably and permanently at room temperature. The use of double-axis arranged tools greatly shortens the processing cycle, shortens the tool change time between tool setting stations, and saves free processing time.
CNC lathes can also be equipped with automatic feeding devices, enabling fully automatic manufacturing on a single machine, thereby reducing labor costs and product defect rates. They are ideal for mass production of precision shaft parts such as Dixon Zero Turn Lawn Mower Parts, Parts for Gravely Zero Turn and Parts for Toro Zero Turn.
2.What is a CNC lathe?
Central lathes are also called central CNC lathes or central automatic lathes. Traditional lathes use mobile tools to work. Through the rotation of the spindle, the tool moves in all directions to achieve the processing of parts such as Dixon Zero Turn Lawn Mower Parts, Parts for Gravely Zero Turn and Parts for Toro Zero Turn.
The CNC lathe does not need to rotate and switch the tool, just move the workpiece up and down. Part machining can be carried out by the rotation and movement of the spindle, and the material can be fed multiple times. Compared with the traditional lathe, the center guide lathe can produce precision machined parts by using the center guide bush, which has great advantages in the processing of slender shaft parts.
The center guide sleeve can move and switch in various directions according to the position or direction of Z2, X2, and C2. The main function is to perform material splicing and auxiliary processing on the spindle. Subsequent machining of some parts requires corresponding tool holder machining on the sub-spindle, and the control channel used is separate from the main shaft, so that the sub-spindle and the main shaft will not interfere with each other. In actual processing, two spindles are used at the same time, which greatly improves the processing efficiency.
3.What are the advantages of CNC lathes?
1) Continuous processing
Usually, the maximum headstock travel of the centering machine lathe is more than 200mm. If the part length is 5mm, the centering machine lathe can process 20-30 parts continuously in one clamping.
2) High stiffness
When turning, the automatic lathe holds the material in the nearest position. So the stiffness is very good. Imagine this situation if the lathe clamps the part and the tool is machining the part a few millimeters away from the fixture. How rigid is it?
3) One-time processing
The automatic lathe with a centering machine has both CNC turning and milling service functions, and the complexity of one processing is also better than that of the old automatic lathe. Since the spindle Z can move back and forth, the tool can also move in the X and Y directions, so that the centering machine lathe can realize three-dimensional processing and complete the processing at one time.
4.What are the limitations of CNC lathes?
The biggest limitation of a walking-type automatic lathe is the diameter of the bar. At present, the largest CNC lathe with centering machine can only process parts with a diameter of 38mm.
5.Summary
The CNC lathe is a high-precision processing equipment, which can complete complex processing such as turning, milling, drilling, boring, tapping, and engraving at one time. The automatic lathe is mainly used for precision hardware processing and mass production of special-shaped shafts.
The CNC lathe has high-precision, high-intelligence technology, adopts high-precision, high-rigidity, built-in electric spindle and high-precision bearings, which can be matched with the stator and rotor. The accuracy of the spindle is still stable under high-speed rotation, and the error is extremely small.
