In machining, the surface quality of the workpiece is an inescapable link. As the requirements for surface quality become higher and higher, how to improve processing efficiency and reduce production costs while ensuring processing quality has become an important issue in improving the market. The key to competitiveness is that although there are options such as precision milling and milling instead of grinding, the processing effect of surface precision milling cutters is still not ideal in many cases. There are three main reasons: the processing efficiency is not high, and the spindle speed is too high. The blade wears quickly and has a short service life. Super-hard blades are expensive, have high production costs, and are not economical. The indexable flat surface super-finishing cutter of Songde Tools is optimized for these problems.
Using carbide blades, through the optimized design of the arc shape of the blade edge and the reasonable design of the installation angle of the blade on the cutter body, the surface roughness of the processed plane can reach Ra{{0}}.8~0.4, and the highest can reach Ra0 .2 . Then match the optimal cutting parameters to achieve the effect of no texture on the machined surface.
The blade cutting edge is elliptical, which can eliminate the influence of the machine tool spindle tilt and achieve high-speed feed precision milling.
The blade can be mounted on left-hand fine milling cutter and right-hand fine milling cutter. The blade has 8 cutting edges. The blade has long service life, good economy, and high cost performance.
With the addition of these factors, the indexable plane super-precision milling cutter can cope with a wide range of processing materials, and has excellent processing performance in processing materials with higher hardness such as ductile iron, vermicular graphite cast iron, and steel parts.
When customers process hydraulic valves, the original product life is unstable and the processing efficiency is low. After using this plane super-precision milling cutter, the efficiency is significantly improved, the surface roughness reaches Ra0.4, the tool life is increased by nearly 30%, and the stability is good, reflecting the advantage of tool cost.
