Problems solved by technology

[0003] In the rough machining of the scroll groove, because the groove of the scroll shell is deep, a tool with a relatively large length and diameter is required, and both sides of the milling cutter participate in the cutting at the same time, and the down milling and up milling are carried out alternately, and the force is unbalanced. It will lead to poor chip breaking or even tool breakage, which will affect the tool life

Embodiment Construction

[0027] The present invention discloses a tooth-broken rough milling cutter, which is used for high-speed, superhard precision cutters in advanced mechanical equipment and devices in automatic machinery and equipment, specifically a round tooth-broken rough machining end mill, which can be applied to Rough machining of scroll housings.

[0028] Such as figure 1 As shown, the broken tooth rough milling cutter 100 includes: a head 10, a transition portion 20 connected to the head 10, and a shank 30 connected to the transition portion 20, wherein one end of the transition portion 20 is connected to the transition portion 20 The handle 30 is connected, and the other end of the transition part 20 is connected with the head 10 .

[0029] The head 10 is provided with three cutting edges 11 at equal intervals, and chip removal grooves 12 are arranged between adjacent cutting edges 11 .

[0030] The diameter of the head 10 is d1, and the length of the head 10 is L4, which is generally...

Abstract

The invention provides a fracture-toothed rough milling cutter which comprises a head part, a transition part and a handle part, wherein the transition part is connected with the head part; the handle part is connected with the transition part; the head part is provided with a plurality of cutting edges and chip discharging slots located between the adjacent cutting edges; the cutting edges have a uniformly distributed fracture-toothed structure. The cutting part is designed to be of a fracture-toothed structure, so that the chip cutting capability is enhanced, the rigidity of a fracture tooth is increased, the possibility of damaging caused by insufficient strength of the fracture tooth is reduced, the overall strength of the cutter is enhanced and the service life and durability of the cutter are promoted; when used for processing a vortex slot, the fracture-toothed rough milling cutter is long in service life and keeps better chip-breaking function; the fracture-toothed rough milling cutter is widely applied to milling of the vortex slot.

Description

technical field [0001] The invention belongs to the technical field of milling cutters, in particular to a rough milling cutter with broken teeth. Background technique [0002] To process the groove in the vortex shell, since the blank contains pre-groove, a rough milling cutter is used to process the milling groove in the center, the depth of cut is 4xd1 (d1 is the diameter of the cutter blade), and both sides of the milling cutter participate in cutting at the same time, and the cutting width is about 1mm respectively. The line speed is 70m / min, and the feed is 0.14mm / r per revolution. The workpiece material is HT250, and the hardness is about HB220. It is required that the straightness of the groove wall is better up and down, and the expected tool life is reached. [0003] In the rough machining of the scroll groove, because the groove of the scroll shell is deep, a tool with a relatively large length and diameter is required, and both sides of the milling cutter parti...
