Abstract
The utility model discloses a carbide disk groove milling cutter, including the base member, seted up the cutter arbor mounting hole on the base member, there is the keyway on the mounting hole, and the surface of base member is equipped with multirow sword tooth along its circumference, and the quantity of sword tooth is equipped with the chip groove between the adjacent sword tooth more than 60 teeth, and the slope opposite direction of adjacent chip groove, its contained angle are a1The groove bottom of the chip groove is arc-shaped, and an included angle a is formed between two sides of the chip groove2The connection part of the cutter tooth and the base body is in clearance connection. The utility model discloses milling cutter precision is high, convenient to use, and machining efficiency is high, on the basis of guaranteeing the machining precision, has not only reduced intoThis, but also prolonged the life of cutter greatly. Meanwhile, the surface of the substrate can be coated with a hard coating to improve the wear resistance of the cutter, so that the cutting tool is more suitable for dry cutting and more environment-friendly.
Description
Technical Field
The utility model belongs to the technical field of the machining technique and specifically relates to a carbide disk groove milling cutter.
Background
At present, key groove machining is mainly conducted by using a two-edge key groove milling cutter or a three-edge disc type high-speed steel milling cutter. The double-edge key groove milling cutter is simple to manufacture, but has extremely low processing efficiency, and is easy to break due to insufficient rigidity of the cutter when the key groove with a large depth-width ratio is processed. And the three-edge disc type high-speed steel milling cutter has the advantages of less tooth number, low precision, low cutting speed and low machining efficiency.
Disclosure of Invention
The utility model aims to solve the technical problem that a carbide disk groove milling cutter that precision is high, production efficiency is high is proposed.
In order to solve the technical problem, the utility model relates to a carbide disk groove milling cutter includes the base member, the cutter arbor mounting hole has been seted up on the base member, there is the keyway on the mounting hole, the surface of base member is equipped with multirow sword tooth along its circumference, the quantity of sword tooth is more than 60 teeth, and is adjacent be equipped with the chip groove between the sword tooth, and is adjacent the incline opposite direction of chip groove, its contained angle are an1The groove bottom of the chip groove is arc-shaped R3The two sides of the chip groove form an included angle a2The connection part of the cutter tooth and the base body is in clearance connection (the clearance part of the cutter tooth and the base body is in an arc R shape1、R2Connected).
According to the hard alloy disc type slot milling cutter, the base body is made of hard alloy materials.
According to the hard alloy disc type slot milling cutter, the substrate is subjected to surface strengthening treatment, and the surface is coated with the hard coating.
The utility model discloses owing to adopted above-mentioned technical structure, convenient to use, machining efficiency is high, on the basis of guaranteeing the machining precision, not only the cost is reduced has prolonged the life of cutter moreover greatly. Meanwhile, the hard coating coated on the surface of the substrate increases the wear resistance of the cutter, is more suitable for dry cutting and is more environment-friendly.
Drawings
Fig. 1 is a schematic structural diagram of the disc type slot milling cutter of the present invention;
FIG. 2 is a schematic side view of the structure of FIG. 1;
fig. 3 is a partial enlarged view of the P direction in fig. 1.
Detailed Description
As shown in fig. 1 and 2, the utility model discloses carbide disk groove milling cutter includes base member 1, has seted up cutter arbor mounting hole 2 on the base member 1, is equipped with keyway 3 on the cutter arbor mounting hole 2. The outer surface of the base body 1 is provided with a plurality of rows of cutter teeth 4 along the circumferential direction, and the number of the cutter teeth 4 is 60 or more than 60. The adjacent flute 5 is arranged between the adjacent cutter teeth 4, the inclination directions of the adjacent flute 5 are opposite, and the included angle is a1(please also refer to fig. 3). The groove bottom of the chip groove 5 is arc-shaped R3The two sides of the chip groove 5 form an included angle a2. The connection part of the cutter teeth 4 and the base body 1 is in clearance connection, and the clearance parts are respectively in arc shape R1、R2Connecting the cutter teeth 4 and the base body 1. In the embodiment, the substrate 1 is made of a hard alloy material (such as a super-microcrystalline material) with high strength and good wear resistance, so that the service life of the cutter is prolonged, the replacement frequency is greatly reduced, the process is simple, and the cutting precision is ensured. Meanwhile, the substrate 1 is subjected to surface strengthening treatment, and the surface is coated with a hard coating, so that the method is more suitable for green and environment-friendly dry cutting.
Claims (3)
