With the increasing precision of products in the manufacturing industry, vertical lathes have emerged, with the main starting point being to solve related problems such as automatic machining and precision machining of various mechanical parts. In the future, many professional technicians have found that some traditional CNC lathes often do not have sufficient machining accuracy or meet the required machining requirements. Therefore, they constantly seek new solutions to the problem, and the emergence of this equipment effectively solves this problem.
Vertical lathe is an automated machine tool with high accuracy and good efficiency. Made of high-strength cast iron, the axial guide rails are made of plastic coated,cnc teflon machining and widened rectangular sliding rails, which have undergone medium frequency quenching and precision scraping treatment. Equipped with a multi-station turret or power turret, it has a wide range of processing performance and can process complex workpieces such as linear cylinders, oblique cylinders, arcs, and various threads, grooves, worms, etc. It has various compensation functions such as linear interpolation and arc interpolation, and has played a good economic effect in the mass production of complex parts.
Special attention should be paid to measures to reduce the impact of thermal deformation on vertical lathes, and commonly used measures are as follows:
1. Improve structural layout
For example, the heat source is symmetrical and adopts a thermally symmetric structure; Adopting inclined bed, flat bed, and inclined sliding plate structures; Due to structural limitations, thermal balance measures are adopted.
2. Take strong cooling measures for cutting parts
The amount of thermal debris that falls on workbenches, beds, and other parts during large-scale cutting is an important heat source. Modern CNC machine tools, especially machining centers and CNC lathes, generally use multi nozzle, high flow coolant to cool and remove these hot chips, and use large capacity circulating coolant or cooling devices to control temperature rise.
3. Control temperature rise
Used for aluminum parts manufacturing and heating components (such as headstock, hydrostatic guide hydraulic oil, etc.), using heat dissipation, air cooling, and liquid cooling to control temperature rise and absorb heat generated by heat sources is a measure to reduce the impact of thermal deformation.
4. Thermal displacement compensation
Predict the thermal deformation law, establish a mathematical model and store it in a computer for real-time compensation.I hope the above content can help everyone better understand this device.
