Numerical control tool grinder used for grinding of disc milling cutter blade

Abstract

The invention relates to a numerical control tool grinder used for grinding of a disc milling cutter blade. The numerical control tool grinder is characterized by comprising a lathe bed (16), an upright post (7), a transverse worktable, a longitudinal worktable, a numerical control rotating worktable (12), a vertical feeding carriage (8) and a grinding electric main shaft (9), wherein the transverse worktable and the longitudinal worktable forms a cross sliding table structure so as to be assembled on the lathe bed (16); and the numerical control rotating worktable (12) is assembled on the transverse worktable in an inclination manner, and a disc cutter to be grinded is installed on a positioning core shaft which is fixedly connected with the numerical control rotating worktable (12). The numerical control tool grinder provided by the invention adopts a multi-shaft numerical control linkage lathe, the kinematic accuracy of the lathe is high, the grinding of complex cambered surface is realized, the grinding of a disc cutter blade shape is met, and the formation problem of cutters such as large-scale and small-batch gears, screw rods and worms is solved.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment, in particular to a numerically controlled tool grinder used for sharpening disc milling cutter blades. Background technique [0002] Forming disc milling cutter is used for milling of helical surfaces such as gears and screws. It is composed of a cutter body, blades and locking screws. It is a common tool. The commonly used tool materials for disc milling cutters are integral high-speed steel and carbide inserts. The carbide inserts can be divided into non-regrindable carbide inserts and regrindable carbide inserts. Due to the low cutting line speed of high-speed steel tools (about 40m / min), the processing efficiency and tool durability are very low. At present, they are generally not used in batch occasions such as gears and screws for powerful milling. [0003] The surface of the non-regrinding carbide insert is coated with a very thin layer of titanium carbide or titanium nitrid...
