AI Technical Summary
The existing indexable machine clamping face milling cutters are prone to loose cutting during the cutting process, especially when the peripheral edge cutting depth is large, the single-hole screw holes are insufficiently compressed, resulting in low machining efficiency.
The double-hole A-type blade design is adopted. By setting multiple blade grooves and positioning holes on the face milling cutter body, double-hole double-screws are used to tighten the blade to ensure the tightening force of the blade and increase the processing depth and efficiency.
It effectively improves the compression force of the insert, enhances cutting stability and machining efficiency, solves the problem of cutting looseness, and improves the overall performance of the face milling cutter.

Technical Field
[0001] The utility model relates to the technical field of cutting equipment, in particular to a face milling cutter with a double-hole A-shaped blade. Background Art
[0002] The face milling cutter has cutting edges on the end face and outer circle perpendicular to the tool bar. It is mainly used for milling planes. The face milling cutter has good rigidity, can adopt a large feed rate, and has multiple teeth involved in cutting at the same time, and has good working stability. Face milling cutters are divided into two categories. One is the welding method, and the other is to directly install the carbide blade on the milling cutter body and then fix it with screws. It is an indexable machine clamped face milling cutter.
[0003] The inventors have found in their daily work that the current indexable machine-clamped face milling cutter blades are mostly vertically mounted and flat-mounted. Flat-mounted blades mostly use A-type blades, square blades, and polygonal blades depending on the size of the main rake angle; A-type blades are mostly pressed by a screw hole. For face milling cutters with a large cutting depth of the peripheral blade, A-type blades with long edges are required. Using a screw hole to press them can easily cause the cutting to loosen during the cutting process. Utility Model Content
