How to shorten the processing auxiliary time of the machining center?

1. How to shorten the processing auxiliary time of the machining center

Before answering the question "how to shorten the auxiliary time of machining center", let's first understand what is the auxiliary time of machining center. The processing auxiliary time of the machining center is the mechanical movement time of some indirect machining workpieces such as alignment of the workpiece, tool setting time, tool change time, etc. The time occupied by these mechanical movements is called the auxiliary processing time of the machining center.

So how do we shorten the auxiliary time of the machining center? For the alignment and tool setting of the workpiece, we can use the process positioning platform on the machining center. For tool change, you can choose some tool magazines with fast tool change speed, such as the hat-style tool magazine and arm-style tool magazine used on machining centers. Choosing the arm-style tool magazine can save tool change time. Machining center manufacturers

2. What are the benefits of using the process positioning platform in the machining center

The process positioning platform eliminates the need for table alignment and tool setting in the x and y directions when installing the workpiece. Compared with traditional auxiliary operations, it can save about 90% to 95% of auxiliary time, and the effective utilization rate of machine tools has increased from 57% to 68% of traditional auxiliary operations to 92% to 96%. More expensive CNC milling machines and expensive The depreciation cost of the advanced processing center can also be greatly reduced, and the economic benefits are very obvious.

Moreover, multiple workpieces can be clamped, especially for the processing of small parts, and the benefits are more obvious. The traditional workpiece clamping method must complete all the processing work required by the processing procedure after the workpiece is installed once, and other workpieces cannot be replaced for urgent processing in the middle. After adopting the general-purpose process positioning platform, as long as the positioning reference of the workpiece or fixture meets the requirements of the positioning platform, other workpieces that need to be processed can be replaced at any time for processing. . This makes CNC milling machines and machining centers very flexible.

3. The tool library selected by the machining center can increase the tool change speed

There are many different forms of machining center tool magazines, such as bamboo hat type, knife arm type, synchronous type, flying saucer type and many other different tool magazines. The tool magazines used in ordinary vertical machining centers are only bamboo hat type and knife arm type. The tool change speed of the knife arm tool magazine can save 50% of the time compared with the hat style tool magazine. If it is in mass production, it is more suitable to use the knife arm tool magazine.

The synchronous tool magazine and flying saucer tool magazine are unique tool magazines for high-speed machining centers and drilling centers. The tool magazine for high-speed machine tools also has a knife arm magazine, and the tool change speed of these two tool magazines Both are much faster than the arm-type tool magazine, and the tool change can be completed within one second at the fastest, which can save processing auxiliary time, but the effect is not as obvious as the comparison between the hat-type tool magazine and the knife-arm tool magazine.
