CNC lathe processing objects and process equipment
A CNC lathe processing object 1. High precision parts Because of the rigidity of CNC lathes, high precision in manufacturing and tool setting, and the ability to manually and accurately perform manual or even automatic compensation, it is capable of machining parts with high dimensional accuracy. In some occasions, you can use a car instead. In addition, because the tool movement during CNC turning is achieved through high-precision interpolation operations and servo drive, coupled with the rigidity of the machine tool and high manufacturing precision, it can process high straightness, roundness and cylindricity of the busbar. Parts. 2. Rotary parts with good surface roughness The CNC lathe can machine parts with small surface roughness, not only because of the rigidity of the machine tool and high manufacturing precision, but also because of its constant-line-speed cutting function. The surface roughness depends on the feed rate and the cutting speed in the case of material, finishing load, and tool setting. Using the constant-speed cutting function of the CNC lathe, the best linear speed can be used to cut the end face so that the cut-out roughness is small and consistent. CNC lathes are also suitable for turning parts with different surface roughness requirements. Smaller areas can be achieved by reducing the feed rate, which is not possible on conventional lathes. 3. Parts with complex contours The CNC lathe has an arc interpolation function, so the circular arc contour can be directly processed using an arc command. CNC lathes can also be machined to contour rotary parts consisting of arbitrary plane curves, which can both process the curves described by the equations and can also process list curves. If turning cylindrical parts and conical parts can use either traditional lathes or CNC lathes, turning CNC turning lathes can only use CNC lathes. 4. Parts with special thread types The threads that traditional lathes can cut are quite limited. It can only process straight and taper surface male and female threads with equal pitches, and a lathe can only process several kinds of pitches. The CNC lathe can not only process any straight pitch, taper, male, female, and face threads, but also can process incremental pitch, reduced pitch, and threads that require a smooth transition between pitch and pitch. Spindle steering does not have to be alternated like a traditional lathe when machining a thread on a CNC lathe. It can be cycled with a knife and a knife until it is completed, so it is efficient in turning threads. CNC lathes are also equipped with precision thread cutting functions, coupled with the general use of carbide forming blades, and can use a higher speed, so turning out the thread with high precision, small surface roughness. It can be said that screw parts, including screws, are suitable for machining on CNC lathes. 5. Ultra-precision, ultra-low surface roughness parts Disks, video recorder heads, laser printer facets, rotary drums for photocopiers, lenses and molds for optical devices such as cameras, and contact lenses require high profile accuracy and extremely low surface roughness values. For machining on high-precision, high-performance CNC lathes. Plastic astigmatism lenses, which were difficult to process in the past, can now be processed on CNC lathes. The precision of super-finishing can reach 0.1μm and the surface roughness can reach 0.02μm. The material of super-finished turning parts was previously mainly metal, and has now been expanded to plastics and ceramics. 1. Chuck of CNC lathe The hydraulic chuck is an important accessory for clamping workpieces during CNC turning operations. Ordinary hydraulic chucks can be used for general rotary parts; special chucks are required for parts where the parts are not clamped; Spring chucks are used when machining parts. Spring chuck 2. Tailstock of CNC lathe For parts with a large ratio of axial dimension to radial dimension, the end of the component needs to be supported by a live tip mounted on a hydraulic tailstock to ensure correct machining of the component. Tailstocks have common hydraulic tailstocks and programmable hydraulic tailstocks. Programmable hydraulic tailstock 3. Tool holder of CNC lathe The tool holder is a very important part of the CNC lathe. According to its function, CNC lathes, the number of tools that can be installed on the tool holder—generally 8, 10, 12 or 16, and some CNC lathes can install more tools. The structure of the tool holder is generally rotary type. The tool is installed on the tool holder in the circumferential direction and can be installed with radial turning tools, axial turning tools, drill bits, and boring tools. The turning center can also be equipped with axial cutters and radial cutters. The tool holders of a few CNC lathes are straight-lined and the cutters are installed along a straight line. Tool holder of CNC lathe CNC lathes can be equipped with two toolholders: 1) The special tool holder is developed by the lathe manufacturer itself, and the used tool holder is also dedicated. This tool holder has the advantage of low manufacturing cost but lacks versatility. 2) General tool holders According to certain general standards, tool holders manufactured by CNC lathe manufacturers can be selected according to the functional requirements of CNC lathes. 4. Milling power head of CNC lathe Installing a milling head on a CNC lathe toolholder can greatly expand the machining capabilities of CNC lathes. Milling power head
