Over the years, users in accordance with the standard, interchange the use of a variety of tool manufacturers produced by the milling cutter and blade. However, these standards make various restrictions on milling cutters and inserts, including the shape and thickness of the inserts, the inscribed circle of the cutting inserts, the size of the holder and wedge clamping parts, and the size of the cutter body. Due to the limited design range of blade material, edge and chip breaking groove, the tool suppliers and users who abide by the standard are limited by the machining function.
However, today, the concept of milling cutter tends to be flexible, which provides tool developers with the freedom to adopt new tools and blade design. These designs can be optimized, and the use of new tool concept can better solve the problems of machining safety, accuracy, appearance quality, metal removal rate, tool overhang, high-speed cutting, and the ability of different cutting paths.
Today’s milling tools are constantly optimized to meet the needs of modern production, machine tools and data, and are widely accepted by all industries. The new tool can remove metal several times faster, with smaller cutting force and better orientation. Its typical runout is only a fraction of the old standard tool. Therefore, the machining tolerance can always be controlled in a smaller range, and the loss of cutting edge is also smaller and more ideal. The axial and radial runout are very small, which means that the accuracy of the cutting edge is improved, so the appearance quality of the workpiece is better, the tolerance is smaller, the tool life is longer, and the cutting load is more uniform, so as to improve the cutting speed and reduce the noise, vibration and loss.
The use of tools also helps to increase spindle speed, high-speed feed and hard part milling, and expands the opportunities for dry cutting. The design of these cutting tools is more concise, and the workload and time required for adjustment and maintenance are very small. The cutter body is rigid and accurate in size. It is made of pre hardened steel, which ensures that the blade is accurately and firmly installed on the milling cutter body, and the appropriate pitch can be selected according to different applications.
The new milling tools use the blade material and groove type developed for specific data or process. The functions and achievements of the new milling tools with these blades are far better than those of ISO or ans standard tools and blades. Compared with most standard inserts, modern new inserts and tools can provide larger rake angle and more complex groove, thus reducing the cutting force and forming the synergistic effect of faster and more stable metal removal.
