Problems solved by technology

[0002] Most of the hole processing in the current technology is directly drilled with a drilling tool. This kind of tool has high drilling efficiency, but if you want to process holes with different diameters on a machine tool, you need drills with different diameters to process them. Time-consuming, and the cost of the tool is relatively high
The drill bit is unable to complete the processing of the groove
For milling cutters, holes with different diameters can be processed. The disadvantage is that if the diameter of the machined hole is equal to or slightly larger than the diameter of the milling cutter, the milling cutter cannot process the holes.

Abstract

The invention discloses a hole groove milling cutter. The hole groove milling cutter comprises a cutter body, a first blade and at least one second blade, wherein the cutter body comprises a cutter bar; two spiral parts, which are symmetrical in a radial direction, are arranged on the cutter bar axially; one side of the first blade is arranged on a first spiral part of the cutter bar in a manner of passing through the axial center of the cutter bar; a cutting part of the first blade is positioned at the end face of the first spiral part; at least one second blade is arranged on a second spiral part of the cutter bar and provided with two cutting parts; the two cutting parts are positioned at the end face and side edge of the second spiral part respectively. The hole groove milling cutter is capable of drilling holes and processing milling grooves by not replacing the cutter, so that the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to an integrated cutting tool for hole processing, in particular to a hole milling cutter. Background technique [0002] Most of the hole processing in the current technology is directly drilled with a drilling tool. This kind of tool has high drilling efficiency, but if you want to process holes with different diameters on a machine tool, you need drills with different diameters to process them. It is labor-intensive and time-consuming, and the cost of the tool is relatively high. Drill bit can't finish the processing to groove especially. For milling cutters, holes with different apertures can be processed. The disadvantage is that if the diameter of the processed aperture is equal to or slightly larger than the diameter of the milling cutter, the milling cutter cannot process the holes. Contents of the invention [0003] The invention designs and develops a slot milling cutter, which can realize drilling and slot milling wi...
