Features and machining principles of machining centers

2024-04-10

1. Process centralization

Machining centers are equipped with tool magazines and can automatically change tools, which can realize multi-process machining of workpieces. After the workpieces are clamped at one time, the numerical control system can control the machine tool according to different processes, automatically selecting and replacing the tools, adjusting the spindle speed, feed, and motion trajectory. Modern machining centers to a greater extent so that the workpiece in a clamping, to achieve multi-surface, multi-featured, multi-station continuous, efficient, high-precision machining, that is, process concentration. This is the most prominent feature of the machining center.

2. Strong adaptability to machining objects

Machining centers can realize flexible production, production flexibility is not only reflected in the rapid response to special requirements, but also can quickly realize mass production, improve market competitiveness.

3. High machining accuracy

Machining center with other CNC machine tools have the same characteristics of high machining accuracy, and machining center due to the machining process is concentrated to avoid multiple clamping, so the machining accuracy is higher, the processing quality is more stable.

4. High machining efficiency

The time required for parts processing includes two parts: motorized time and auxiliary time. Machining centers with tool magazines and automatic tool changer, in a machine tool can focus on the completion of a variety of processes, thus reducing the workpiece clamping, measurement and machine tool adjustment time, reduce the turnover of semi-finished products, handling and storage time, so that the cutting utilization rate of CNC machine tools (cutting time and the ratio of the time to start) is higher than the ordinary machine tool 3 to 4 times, up to more than 80%.

5. Reduce the labor intensity of the operator

Machining center parts processing is completed automatically according to the pre-programmed program, the operator in addition to loading and unloading parts, key processes of intermediate measurement and observation of machine tool operation, do not need to carry out heavy repetitive manual operation, labor intensity and tension can be greatly reduced, the labor conditions have also been greatly improved.

6. High economic efficiency

The use of machining centers to process parts, the equipment costs shared in each part is more expensive, but in the case of single-piece, small batch production, you can save a lot of other aspects of the cost, so you can get good economic benefits. For example, after the part is mounted on the machine, adjustment, machining and inspection times can be shortened, reducing direct production costs. In addition, hardware investment is reduced because machining centers do not need to make other jigs and fixtures for machining parts, and production costs are further reduced because machining centers offer stable machining quality and reduced scrap rates.
