The difference between ordinary lathe and CNC lathe

Different composition of 1. structure Ordinary lathe feed system includes a feed box and a skateboard box, which is used to turn the surface of the workpiece with a lead screw and a light bar; CNC lathe has a numerical control system, feed and hydraulic systems, etc., and the surface thread of the workpiece is processed in the turning center. The latter is more conducive to production management. Different 2. machining methods Ordinary lathe polishing workpiece to manual operation, workers should be in strict accordance with the provisions of the lathe manual shaking tool for detailed processing of parts; CNC lathe is in accordance with the technical personnel through the data control issued by the regulations of the instructions, the product parts are directly processed. 3. processing precision is different Ordinary lathes can process fewer types of parts, due to the degree of automation is not enough, machining accuracy and parts quality is not as CNC lathes; CNC lathes by changing the control program can process complex parts, processing quality stability and repeatability are higher. Different 4. applicable conditions Ordinary lathes are more flexible because of manual operation and large force on equipment, so it is not easy to process complex parts and it is more convenient to process single products. The same large equipment of numerical control lathes has less force and more precise parts, which is suitable for more complex processing and production of large quantities of mechanical parts. 5. cost maintenance cost is different The cost of ordinary lathes is low, the investment is small, and the debugging can be carried out manually before use. The maintenance of ordinary lathes is mainly due to the wear and tear between components, and the maintenance cost is not high. The use cost of CNC lathes is high, the investment is large, and a number of debugging are required before use. The preparatory work is complicated, and all systems including CNC programs are regularly maintained, and the maintenance cost is high. 6. installation requirements are different Ordinary lathes should strictly control the ambient temperature, humidity, power supply voltage and other conditions. The numerical control lathe shall level the position on the basis of avoiding direct sunlight and humid air flow as far as possible, and the reading of the level shall not exceed 0.04/1000mm.
