Advantages of Nitrogen Freezing to Remove Burrs

Advantages of nitrogen freezing to remove burrs 1. The operation is simple, ordinary workers can operate the machine skillfully after a period of training, and the advanced automatic control system can prevent workers from misoperation 2.High production efficiency, a frozen deburring machine average daily processing amount equivalent to 50-80 skilled workers trim the work load 3.High trimming precision, it can remove very small and hidden flash, without limited by product shape, high pass rate and stable trimming quality 4.Do not damage the surface of products, improve the appearance of products quality, increase the service life of products 5.Small area, a frozen trimming machine and auxiliary equipment only 10 square meters 6.Reduce the use cost of the mold and the cost of the glue material. The equipment does not need the edge tearing, only the flying edge is required to be as thin as 0.2mm, the overflow groove is as small as possible, and the flying edge allowance is only 1/5-1/10 of the ripping mold.
