Description
Technical Field
The utility model belongs to the field of CNC machining, and particularly relates to a circular nose milling cutter for an indexing cutter groove.
Background
In the 3C industry, machining tools for parts such as mobile phones or computers have extremely high requirements, and are suitable for large cutting, such as intermittent cutting of the margins of the work price, anti-collapse, anti-vibration and the like, and milling tools are rotary tools for milling machining and provided with one or more cutter teeth. When in work, each cutter tooth cuts off the allowance of the work price intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces, cutting workpieces and the like on milling machines. The existing circular nose knife has serious abrasion of the cutting edge after a period of processing, and the service life of the knife is lower. Therefore, there is a need to provide a technical means to solve the above-mentioned drawbacks.
Disclosure of Invention
The utility model provides a circular nose milling cutter with an indexing cutter groove for solving the technical problems.
The utility model adopts the following solution scheme for realizing the technical effects:
an indexing cutter slot round nose milling cutter comprises a cutter handle, a cutting part, a peripheral edge and an end edge; the cutting part is arranged at the front end of the cutter handle; four cutting edges are respectively spirally arranged on the outer side of the cutting part to the right, and one cutter groove is arranged between every two adjacent milling cutting edges, namely, four cutter grooves are arranged on the outer side of the cutting part; the helix angles of the four cutter grooves are respectively arranged in different graduation manners; the peripheral edge is arranged on the outer side of the milling margin; the front angle of the peripheral edge is 2 degrees; the first relief angle of the peripheral edge is 8 degrees; the second relief angle of the peripheral edge is 15 degrees; the end blade is provided at the front end of the cutting portion.
Preferably, the helix angles of the four flutes are respectively provided in different indexing arrangements of 33 degrees to 35 degrees.
Preferably, the helix angle of the peripheral edge is 35 degrees.
Preferably, the rake angle of the end edge is 2 degrees; the first relief angle of the end edge is 6 degrees; the second relief angle of the end edge is 16 degrees.
The beneficial effects of the utility model are as follows: the cutter parameters are optimized from the design angle, the front angle and the rear angle of the peripheral edge are optimized aiming at the cutter abrasion part, the friction area between the cutting edge margin and the milling surface is reduced, and the service life of the circular nose cutter is prolonged.
