Today, thousands of processing companies in the United States are engaged in the processing of precision engraving machines, molds stamping dies of Yiming carving milling machines. The high-speed milling of these large-scale molds seems to be unlimited consumables hard tools for industrial products. In order to meet customer expectations higher tool quality, shorter turning time lower cost competitive pressure, many mold engraving milling machine manufacturers are upgrading their high-speed finishing processes. The main advantage of this method is that the finish of the machined surface is sufficient to significantly reduce even eliminate manual polishing on the worktable.

These auxiliary operations usually account for 2530% of the total manufacturing time.

The high-speed finish machining of mould depends on the spindle speed ability of today's machine tool. Whether the equipment used is a small vertical machining center a new large horizontal machining center, the spindle speed of 10000 rpm is very common now. This speed is easily achieved by today's tool safety clamping methods combined with precision spring clamps thermal expansion handles, mechanical hydraulic clamping. An equally important concept in high-speed precision mould machining is the high feed rate of cutting tools. In the case of high processing speed, high processing speed good processing effect, the processing depth is small, the step distance is small, the surface finish is good. At present, the tool used for high-speed milling of 55 degree die usually runs at 1200mm / min feed rate. The fine particle cemented carbide blade coated with PVD can obtain brightness of 0.63 μ M. The axial depth radial depth are 0.05 mm 0.25 mm respectively.
