Abstract

The utility model relates to a hole processing tool consisting of a tool body and a blade. The key points lie in that the tool body is a Morse cone, the included angle Beta between the major cutting edge of the blade and the center of the blade is 25-35 degrees, the included angle Kr between an end surface cutting edge and an element end surface is 93-95 degrees and the arc of the tool nose is R0.2max. The advantages include the combination of a reamer and a milling cutter into one, good size precision and surface roughness of a processing hole, correction of hole position, processing of blind holes, simple structure and good use effect.

Description

A kind of aperture knife tool
Technical field
The utility model relates to a kind of machining tool, is specifically related to a kind of process tool of axis hole.
Background technology
The compensating shaft that the oil field is used to drill is generally elongated high temperature alloy spare, will process the blind hole of ¢ 19mm about degree of depth 300mm, circular arc R 0.2max at the bottom of the hole, and general processing method is difficult to realize.The numerically controlled lathe bore hole is oversize owing to knife bar overhangs, and the rigidity deficiency is easy to generate cutter relieving, makes endoporus produce tapering, dimension overproof.Simultaneously, high temperature alloy work hardening phenomenon is serious, when reprocessing part, and material can't be processed, cause product to scrap in a large number, and economic loss is serious.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of good rigidly is provided, precision height, the aperture knife tool that working (machining) efficiency is high.
The utility model is made of cutter hub and blade, it is characterized in that: described cutter hub is third constellations cone not, the main cutting edge of described blade and the angle β of blade center are 25-35 °, and face cutting edge and part end face angle Kr are 93 °-95 °, and tool arc is R0.2max.
The utility model has the advantages that reamer and milling cutter are united two into one that the dimensional accuracy surface roughness of machining hole is good, energy trimming hole position, processing blind hole.Simple in structure, result of use is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, cutter hub, 2, blade, 3, part.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
The utility model is made of cutter hub 1 and blade 2 welding, and the afterbody of cutter hub 1 is to cut flat Mohs cone, makes the convenient taking-up of cutter.Chip pocket is a helical angle, and promptly the main cutting edge of blade 2 and the angle β of blade center are 30 ° of helical angles, and the end tooth tool cutting edge angle is that face cutting edge and part end face angle Kr are 93-95 °.Tool arc is R0.2max.Manufacturing tolerance 0.005mm, to the shank 0.005mm that beats, the end tooth 0.02mm that beats.
Part 3 is erect clamping on vertical machining centre, and the lower surface is propped up and leaned on.The taper shank of cutter hub 1 is contained on the machine tool chief axis, and the rigidity of whole part 3 in process strengthened.Cutter accuracy of manufacture height.The assurance accessory size is qualified.Chip pocket makes chip removal convenient, guarantees the endoporus roughness.The end tooth length feed can be removed material, the position of trimming hole.Tool arc R0.1-0.2mm makes things convenient for processing blind hole.
