CNC vertical lathe is a high-precision and high-efficiency CNC processing equipment. Its use of electric spindle working mode can bring many benefits. Traditionally, vertical lathes use mechanical spindles, which are directly connected to the machine tool itself and cannot rotate freely. CNC vertical lathes using electric spindles can achieve continuously variable speed, high-speed cutting, high-precision machining and other functions, which greatly improves processing efficiency and processing quality. Let us introduce these advantages one by one.
Continuously variable speed
CNC vertical lathes using electric spindles can achieve infinite speed changes. Compared with a mechanical spindle that can only achieve a limited number of rotational speeds, the rotational speed of an electric spindle can be adjusted infinitely, which means that precise speed adjustments can be made as needed during processing to achieve more efficient processing results.
High speed cutting
High-speed cutting is the key to speeding up the machining process. Because the electric spindle is lighter and rotates more smoothly, it can meet higher cutting speed requirements, which is very effective for machining deep grooves and lightweight parts. At the same time, high-speed cutting technology can also reduce cutting forces and cutting temperatures, thereby effectively reducing the risk of part deformation.
High precision machining
CNC vertical lathes can be machined within extremely precise dimensions, so it is important to maintain accuracy during the machining process. The electric spindle has higher precision and reduces errors caused by mechanical friction and vibration. Compared with mechanical spindles, electric spindles have higher precision. Its maximum speed reaches more than 35,000 rpm and the accuracy can reach more than 1 micron.
Easy to change tools
Tool changing is a routine operation of CNC vertical lathe. Traditionally, the spindle needs to be stopped and the spare tool replaced. CNC vertical lathes using electric spindles do not need to stop, and can seamlessly switch tools through the automatic tool changing system, making processing faster and more convenient.
Generally speaking, CNC vertical lathes using electric spindles are more superior than traditional vertical lathes using mechanical spindles. It can achieve many benefits such as continuously variable speed, high-speed cutting, high-precision machining, easy and easy tool replacement, etc., which has a positive role in improving production efficiency, reducing costs, and improving product quality. This is why more and more manufacturers choose to use electric spindles to achieve more efficient processing results.
