Abstract
The utility model relates to the technical field of machining equipment and in particular relates to a high-efficiency end milling cutter. The high-efficiency end milling cutter comprises a cutter body, a slag discharging slot and a cutting edge, wherein the cutter body is a cylinder; the slag discharging slot encircles the lower part of the cutter body; the cutting edge is positioned at the bottom end of the cutter body; the lower end of the cutter body is conical. The lower end of the cutter body is designed to be a cone, and the cutting edge is spirally contracted along the lower end of the cutter body, so that the diameter of the milling cutter is gradually increased from bottom to top to form smooth transition; therefore, the hole milling work is pushed stage by stage and is endowed with hierarchy; the resistance of the milling cutter is reduced; the service life of the milling cutter is prolonged; the hole milling efficiency is greatly improved.
Description
Technical field
The utility model relates to the machining equipment technical field, especially a kind of efficient slotting cutter.
Background technology
In machining, hole processing is the processing technology of commonly using, and industry adopts milling cutter to carry out hole processing usually, and existing milling cutter is all cylinder, the up and down diameter is consistent, but in actual process, the resistance that the milling cutter front end is subject to is maximum, if directly by standard bore hole milling, not only milling cutter is stressed excessive, easy to wear fractureing, and inefficiency are wasted time and energy.
The utility model content
Easily mill is easily broken in order to overcome existing milling cutter, the deficiency of inefficiency, and the utility model provides a kind of efficient slotting cutter.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of efficient slotting cutter, comprise cutter hub, chip area and blade, and cutter hub is cylinder, and chip area is around the cutter hub bottom, and blade is positioned at the cutter hub bottom, and the cutter hub lower end is tapered.
According to another embodiment of the present utility model, further comprise blade in the shape of a spiral, along cutter hub lower end screw-pinch.
The beneficial effects of the utility model are, the cutter hub lower end is designed to cone, blade is taken advantage of a situation in the shape of a spiral along cutter hub lower end screw-pinch, makes the diameter of milling cutter become gradually from the bottom up large, form level and smooth transition, thereby the hole milling operation is advanced step by step, possess level, both reduced the resistance of milling cutter, increase the service life, greatly improved again hole milling efficient.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. cutter hubs in figure, 2. blade, 5. chip area.
The specific embodiment
Be structural representation of the present utility model as Fig. 1, a kind of efficient slotting cutter comprises cutter hub 1, chip area 5 and blade 2, and cutter hub 1 is cylinder, and chip area 5 is around cutter hub 1 bottom, and blade 2 is positioned at cutter hub 1 bottom, and cutter hub 1 lower end is tapered.Blade 2 in the shape of a spiral, along cutter hub 1 lower end screw-pinch.
Cutter hub 1 lower end is designed to cone, blade 2 in the shape of a spiral, take advantage of a situation along cutter hub 1 lower end screw-pinch, make the diameter of milling cutter become gradually from the bottom up large, form level and smooth transition, thereby the hole milling operation is advanced step by step, possesses level, both reduce the resistance of milling cutter, increased the service life, greatly improved again hole milling efficient.
