Choosing cheats for machine tool fixtures

Choose the secret book of jig

The production power varies by several times. Right? CNC lathe machine manufacturer China shares that the conclusion is: nc machine tool selection fixture is not appropriate, so that the production power of nc machine tool significantly decreased.

How to improve the utilization rate of CNC machine tools? Through the analysis of skills, the application of fixture has a great connection. According to the reaction of gold powder, often CNC machine tool in the operation because the fixture selection is not reasonable or improper use, and presented a "slowdown" phenomenon; From another point of view, in the selection and application of CNC fixture can be done, because it contains considerable potential economic benefits.

Correct selection of fixture type is the root of efficient machining

At present, mechanical processing can be divided into two categories according to the production batch: one is single, multi-type, small batch (referred to as small batch production); Another kind is little kind, large quantity (abbreviation large quantity produces). Meanwhile, the former accounts for about 70 to 80 percent of the total output value of mechanical processing, which is the main body of mechanical processing.

Suitable for small batch production of CNC fixture

Small batch production cycle ﹦ produce prepare/waiting time + workpiece processing time for small batch production of "processing time" is very short, and thus "produce prepare/waiting time" the length of the effect on the processing cycle is very important to have table. If you want to improve production power, you must find a way to shorten the production time.

The following three types of small batch production can be given priority to think of CNC fixture:

Modular fixture

Modular fixture is also known as "modular fixture", it consists of a series of machine tool fixture components after standardized planning, different functions, different standard scales, customers can according to the processing requirements, like "building blocks", quickly assembled out of various types of fixture. Because the combination of fixture dispenses with the planning and production of special fixture time, greatly shorten the production preparation time, and thus usefully shorten the small batch production cycle, that is, the progress of production power. Other, the combination fixture also has high positioning accuracy, flexible clamping, recycling and repeated use, production of energy saving materials, the use of low cost and other advantages. Therefore, small batch processing, especially when the shape of goods is more complex can be given priority to consider the use of modular fixture.
