I. Preface CNC CNC lathe processing has been increasingly applied to modern manufacturing, and has the advantage that ordinary lathes cannot match. The CNC lathe processing mainly has the following features:
1. CNC CNC lathe processing transmission chain is short, compared with the ordinary lathe spindle drive is no longer a motor belt gear deputy mechanism speed, but the use of horizontal and vertical feed, respectively, by the two servo motor drive movement is completed, no longer use the hanging wheel, clutch With traditional components, the transmission chain is greatly reduced.
2. High rigidity, in order to match with the high precision of numerical control system, the rigidity of CNC lathe machining is high, in order to meet the high-precision processing requirements.
3. Lightly dragging, the tool holder (workbench) moves using ball screw, with low friction and easy to move. Both ends of the bearing support bearings, the pressure angle is larger than the ordinary bearing, it will be equipped with a good selection at the factory; CNC CNC lathe lubrication part of the use of automatic lubrication oil mist, these measures make the CNC CNC lathe processing mobile light.
Second, CNC lathe processing features 1. The high degree of automation can reduce the operator's manual labor intensity. CNC lathe machining process is automatically completed according to the input program, the operator only need to start the knife, loading and unloading the workpiece, change the tool, in the process of processing, mainly to observe and supervise the operation of the lathe. However, due to the high technical content of CNC lathes, the brain work of operators has been correspondingly improved.
2. CNC CNC lathe processing parts with high precision and stable quality. CNC lathes have high positioning accuracy and repeatable positioning accuracy, and are easier to guarantee the consistency of a batch of parts. As long as the process design and procedures are correct and reasonable, combined with meticulous operation, the parts can be guaranteed high processing accuracy, and it is easy to CNC CNC lathe processing process to implement quality control.
3. CNC CNC lathe processing production efficiency. CNC CNC lathe machining is able to process multiple machining surfaces once again in a clamping process. Generally, only the first part is detected. Therefore, many intermediate processes such as scribe and dimension detection can be processed during normal lathe machining in the province, which reduces the auxiliary time. Moreover, due to the stable quality of parts manufactured by CNC lathes, it is convenient for follow-up processes and its overall efficiency is significantly improved.
4. CNC lathe machining facilitates the development and modification of new products. CNC CNC lathe processing generally does not require a lot of complicated process equipment. By compiling machining programs, parts with complex shapes and high precision can be machined. When the product is remodeled and the design is changed, it is only necessary to change the program without redesign. Tooling. Therefore, CNC CNC lathe processing can greatly shorten the product development cycle, providing a shortcut for research and development of new products, product improvement, and retrofitting.
5. CNC lathe machining can be developed to more advanced manufacturing systems. CNC lathe machining and machining technology are the basis of computer-aided manufacturing.
6. The initial investment in CNC lathe machining is large. This is due to the high cost of CNC lathe machining equipment, the longer first-time preparation cycle, and higher maintenance costs.
7. CNC CNC lathes require high processing and maintenance. CNC lathes are technically intensive mechatronic integrated CNC CNC lathe processing products. Maintenance personnel need to understand both mechanical and microelectronics maintenance knowledge, and also have better maintenance equipment.
Third, suitable for CNC CNC lathe processing parts 1. CNC lathe machining is most suitable for multi-variety small to medium-sized parts. With the gradual reduction of the manufacturing cost of CNC lathes, the processing of large-volume parts has also emerged at home and abroad. When processing very small batches and single pieces of production, it is optional to shorten the debugging time of the program and the preparation time of the tool.
2. High-precision CNC lathe machining parts. Because of the high rigidity and precision of CNC lathe machining, accurate tool setting and easy size compensation, it is possible to machine parts with high dimensional accuracy.
3. CNC lathes machine parts with small surface roughness. In the case of a fixed workpiece and tool material, finishing allowance and tool angle, the surface roughness depends on the cutting speed and the feed rate. Ordinary lathe is a constant speed, different diameter cutting speed is different, such as CNC lathe machining with constant line speed cutting function, car end surface, different diameter outer circle can use the same linear speed, to ensure that the surface roughness value is small and consistent. When processing surfaces with different surface roughness, small feed rates are used for surfaces with small roughness, and large feed rates are used for surfaces with large roughness, and variability is very good. This is difficult to achieve on ordinary lathes.
4. Contoured parts. Arbitrary plane curves can be approximated by straight lines or arcs. CNC lathe machining has circular interpolation functions and can process various complicated contour parts.
IV. Management of CNC Lathes The use of CNC lathes in machining requires both the careful use of operators and scientific management. A sound management system and a scientific production model are effective means to increase production efficiency.
1. Establish and improve a sound management system to effectively control and supervise the work of CNC lathe-related personnel, so that the entire operation of the lathe is controlled.
2. Strengthen the training of technical personnel and technical worker management personnel. CNC machining training is a long-term work and it is a process of continuous improvement. By training the craftsmen, more simplified NC machining processes can be prepared, the procedures can be simplified, and the processing time can be shortened; the skilled workers can improve the operation skills; the management personnel can better understand the characteristics of numerical control equipment, process control, and implement management with modern production management concepts.
3. Scientific organization production. Improve shutdown and waiting for materials, unbalance the production capacity, increase the operating rate of CNC CNC lathe processing, reasonably arrange production beats, and reasonably distribute production tasks. Using the similarity of parts processing, the parts to be processed are categorized so as to be reasonably arranged in the process preparation, production planning and scheduling, and to increase the balance of equipment production capacity. Scientific production batches will greatly reduce the proportion of lathe adjustment time and tool preparation time, and can increase batch efficiency.
4. In order to exert the value of CNC lathe machining, operators must master the principles of CNC lathe operation. Correct operation of lathes according to lathe operating procedures; processing of parts according to process and procedure requirements; coordination of parts, tools, platens, etc. before CNC CNC lathes to avoid interference and collisions; improve technical quality, reduce non-machining time such as loading and correcting; Maintenance and various auxiliary tools ensure accuracy and reliability.
V. Conclusion The application of CNC lathes has become increasingly widespread. How to “manage, use, and maintain” CNC lathes has become an important issue to be solved. The use of CNC lathe machining is not a simple use of equipment. It is an application project with strong sequential properties. Only scientific management, full understanding of the characteristics of CNC lathe processing, coordination of the balance of the various production processes in order to truly play its economic benefits.

Wood lathes can be used to create functional furniture components, beautiful decorative wood projects such as candlesticks and bowls, or even toys such as tops and yo yos. These machines range in size from hobby models that fit on a work bench to large industrial-sized machines weighing hundreds of pounds, but they all share some basic elements. Here are some instructions for using these unique machines. For those in the machining and turning crafts, it`s common knowledge that the Industrial Revolution had a significant impact on the evolution of the lathe and additional machine tools. As humans began developing tools and technology, honing new skills, and began more efficient ways of production, different power sources started to become standard. Motors now required electricity, meaning the conventional way of operating machine tools by human touch was being phased out as more and more machinists were [turning" to automation. But before automation and metalworking became regular practices in the machining world, there was woodturning and thus, wood lathes.
