What is the internal structure of CNC lathe?
CNC lathe is a machine tool that can finish turning and milling. It can be used as both a lathe and a milling machine. Nowadays, both vertical CNC lathes and horizontal CNC lathes belong to CNC lathes.
1、 What is the internal structure of CNC lathe
At present, CNC lathes are mainly of two different types, one is the combination of different processing methods with energy or motion as the core; The other type is the combination based on the principle of compound machine tool and mainly on CNC processing technology. Turning milling compound processing is one of the faster developing processing methods in this field in recent years.CNC lathe: mainly for milling, only X; Y； Z three-axis linkage Z axis is generally a power axis spindle (horizontal plus; special machine is not included in this example) turning milling compound machine: also called a 5-axis dual power head CNC lathe. In addition to milling, it can also be turned. This machine was originally used to process propellers, so as to avoid the loss of accuracy and reference caused by twice clamping. The CNC lathe is a main model of the compound machining machine tool. In addition to the functions on the CNC lathe, it can perform plane milling, drilling, tapping, straight groove, spiral groove and gear milling, it has the compound functions of turning, milling and boring, and can realize the processing concept of one-time clamping and all completion. CNC machine tools that meet all of the following characteristics are CNC lathes:
1) The spindle motor is a servo motor, and the rotation movement and feed movement of the spindle can be linked.
2) In addition to the turret turret of the CNC lathe, at least the power tool shall be configured, or the independent power tool holder shall be configured.
2、 The turning center is also generally a turning milling compound machine tool. Its advantages are:
1) Shorten product manufacturing process chain and improve production efficiency.
The CNC lathe compound center can be equipped with a variety of special tools. The new tool layout can reduce the tool change time and improve the processing efficiency. The turning milling compound processing can realize one-time clamping to complete all or most of the processing procedures, thus greatly shortening the product manufacturing process chain. On the one hand, it reduces the auxiliary production time caused by the change of clamping, and on the other hand, it also reduces the manufacturing cycle and waiting time of tooling and fixtures, which can significantly improve the production efficiency.
2) Reduce clamping times and improve machining accuracy.
The reduction of card installation times avoids the error accumulation caused by the conversion of positioning reference. At the same time, most of the turning milling compound processing equipment at this stage has the function of online detection, which can realize the on-site detection and accuracy control of key data in the manufacturing process, thus improving the processing accuracy of products; The high strength integrated bed design improves the gravity processing ability of hard to cut materials.
3) Reduce floor space and production cost.
The compact and beautiful appearance design improves the space utilization mode, and the maintenance and repair are more convenient to maximize customer satisfaction; Although the single unit price of turning milling compound processing equipment is relatively high, due to the shortening of the manufacturing process chain and the reduction of equipment required for products, as well as the reduction of the number of fixtures, workshop floor space and equipment maintenance costs, it can effectively reduce the investment, production operation and management costs of the overall fixed assets.
