Description

A kind of single-edge spiral milling cutter

Technical field

The utility model belongs to cutting element technical field, specially a kind of single-edge spiral milling cutter.

Background technique

Milling cutter is the rotary cutter for Milling Process, be mainly used on milling machine process plane, step, groove, at Shape surface and cutting workpiece etc..Existing screw-on cutter there are service lifes not high, the unsmooth problem of chip removal, meanwhile, existing spiral The knife handle and cutter head of milling cutter, which are integrally formed, to be made, and in use, cutter head is easy to be worn, and knife handle be very unlikely to by Abrasion needs replacing entire milling cutter, results in the waste of knife handle when tool bit abrasion is along bad when.

Utility model content

The purpose of this utility model is to provide a kind of single-edge spiral milling cutter, which has chip removal unobstructed, use cost It is low, the advantages that knife handle is reusable.

In order to achieve the above objectives, the technical solution of the utility model are as follows:

A kind of single-edge spiral milling cutter, including knife handle and cutter head, the knife handle and cutter head pass through groove cutting ferrule and protrusion clamp The mode of engaging connects.

Further, the cutter head bottom end is provided with the protrusion clamp of regular polygon, and the knife handle front end is provided with and knife The compatible groove cutting ferrule of head protrusion clamp.

Further, the groove cutting ferrule bottom of the knife handle is provided with magnetic part, and the magnetic force energy of the magnetic part will Cutter head protrudes the stable and firm attraction of clamp in groove cutting ferrule, and knife handle and cutter head can be separated freely under artificial action.

Further, the protrusion clamp of the cutter head is octagon clamp.

Further, the diameter of the knife handle is greater than or equal to the diameter of cutter head.

Further, the diameter of the cutter head is 3~12mm, and the length of the cutter head is 8~30mm, the length of the knife handle Degree is 40mm.

Further, the cutter head includes helicla flute and the helical edges that are formed by helicla flute, and the helicla flute is arc-shaped Groove face, helical angle are 45 °, and spiral groove depth is the 50% of sword diameter.

Further, it is provided with secondary chip space in the helical edges, chip removal effect can be increased.

The utility model has the following beneficial effects: single-edge spiral milling cutter described in the utility model has chip removal effect good, make With at low cost, the reusable advantage of knife handle.Cutter head described in the utility model is connected with knife handle by snap fit, can be into Row freely mounts and dismounts, and when tool bit abrasion is along bad when, only needs to change cutter head, and knife handle repeats practical, greatly reduces Cost.The spiral angle of cutter head helicla flute is set as 45 °, and depth is set as the 50% of sword diameter, can achieve preferable chip removal effect Fruit.Secondary chip space is set in helical edges, can be further improved chip removal effect.
