Selection of Tooling Fixture for CNC Machine Tool

The same machine, why the production efficiency is several times different? The conclusion is that the fixture used in CNC machine tools is not suitable, so that the production efficiency of CNC machine tools is greatly reduced. It should be noted that here is the precision combination of flat-end clamp is not the old machine plus vise, vintage machine plus a single function, low manufacturing accuracy, can not be used in groups, short life, not suitable for CNC machine tools, machining centers On use. Here referred to the precision combination of flat-nose pliers is originated in Europe and the United States and other industrial developed countries, specifically for CNC machine tools, machining center features a series of new flat-nose pliers, such products with high flexibility, high positioning accuracy, fast clamping , Can be used in groups and other characteristics, especially for CNC machine tools, machining centers. The following describes the CNC machine tool fixture in the permanent selection and application of permanent magnet fixture.
Electric permanent magnet fixture
Electric permanent magnet fixture is NdFeB and other new permanent magnet materials for the magnetic source, the use of modern magnetic circuit design and design of a new fixture. A large number of machining practice shows that the electric permanent magnet fixture can greatly improve the CNC machining, machining center integrated processing efficiency.
The clamping and loosening process of the permanent magnet fixture takes only about 1 second, thus greatly reducing the clamping time. The positioning and clamping elements of the conventional machine tool fixture occupy a larger space, and the electric permanent magnet fixture does not have these space Components, so compared with the conventional machine fixture, the permanent magnet fixture clamping range is greater, which is conducive to make full use of CNC machine tool table and processing trip, is conducive to improving the overall processing efficiency of CNC machine tools. Electric suction fixture suction is generally 15 ~ 18Kgf / cm2, so be sure to ensure that the suction (clamping force) enough to resist the cutting force, under normal circumstances, the adsorption area should not be less than 30cm2, the clamping force of not less than 450Kgf.
