Abstract
The utility model relates to a skewed-ditch shaped milling cutter, which adopts a rod structure and is provided with a taper shank. A chip removing groove of the milling cutter is manufactured into achute, a front angle is arranged on a front edge surface, the chip removing groove of the milling cutter is a spiral ditch at the angel of 5 degrees to 30 degrees, and the front angle of a front cutter surface is in the range of 2 degrees to 7 degrees. The skewed-ditch shaped milling cutter has the advantages of high cutting efficiency, high processing precision, and good surface-processing quality; and the production efficiency is improved by 2 times to 3 times compared with that of a single-chip milling cutter.
Description
Technical field
The utility model relates to a kind of machining tool, is specifically related to a kind of valley profile milling cutter.
Background technology
At present, along with China's entry into the World Trade Organization, all trades and professions and the world of China integrate with.Constantly introduce external new product.When processing the special shape groove, adopt the monolithic milling cutter more in the past.Because of the monolithic milling cutter once can only be processed a groove, when processing multiple-grooved workpiece, need the processing of tool setting repeatedly, cause that the processing work precision is low, processing cost is high, past, the special type milling cutter of external import is the rod-type milling cutter of straight flute, 0 ° of anterior angle, this milling cutter is at cutting precision, aspects such as cutting ability and efficient and durability all can not satisfy the needs of highly-efficient processing, during this milling cutter processes, cutter is that face contacts with workpiece, when feed is big, the cutter phenomenon will be occurred reining in because of the workpiece shape is special shape, qualified products can not be processed.So working (machining) efficiency is low.Often tool changing is wasted time and energy, and influence is produced.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, can increase work efficiency, the valley profile milling cutter of dimensional accuracy and suface processing quality.
In order to achieve the above object, the technical solution adopted in the utility model is: milling cutter is a bar type structure, has taper shank, and the milling cutter chip area is skewed slot, and lip surface has anterior angle.
The utility model has the advantages that:
1, machining accuracy height: because milling cutter has three cutters tooth that guarantee the tooth pitch precision,, avoided the monolithic milling cutter to add the inaccurate problem of tooth pitch in man-hour, improved machining accuracy so can process three cutter grooves simultaneously;
2, improved profile accuracy: the oblique angle of lip surface is 5 °, realizes inclined cutting, reduces cutting deformation and energy consumption.Also help chip removal.And significantly improve profile accuracy and surface roughness;
3, interchangeability is good: cutter has adopted whole bar type structure, and be to have used high-precision Morse taper shank, can guarantee that cutter is installed on the Digit Control Machine Tool of different model, avoided the monolithic milling cutter to adopt core bar to be installed, the shortcoming that cumulative errors are big, thus the precision that guaranteed to be installed has guaranteed machining accuracy;
4, stock-removing efficiency height: because cutter can three teeth groove of time processing (the monolithic milling cutter once can only be processed a teeth groove), and can guarantee the high accuracy tooth pitch, so production efficiency can improve 2～3 times.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the partial enlarged drawing of blade profile of tooth among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model milling cutter is a bar type structure, has taper shank 1, and milling cutter chip area 2 is skewed slot, and lip surface has anterior angle.
Milling cutter chip area 2 is a 5-30 ° of spiral goove, and the rake face anterior angle is 2～7 °.
Valley profile milling cutter described in the utility model is bar type structure, has taper shank 1, and milling cutter chip area 2 is made skewed slot, and lip surface has anterior angle; Milling cutter chip area 2 is a 5-30 ° of spiral goove, and the rake face anterior angle is 2～7 °, and pitch tolerance is ± 0.005.Because this milling cutter is mounted in and decides the dress milling cutter on the import special purpose machine tool, so taper shank 1 also has strict demand.Taper shank 1 is No. 3 taperings of Mohs, exceeds the tapering deviation and is real useless; Blade profile of tooth 3 is the special tooth profile that is connected with straight line by circular arc, by monosymmetric radius is that the 0.95mm circular arc is connected with the straight line at a coaxial line angle at 45, the junction arc radius is 0.3mm, and arc toothed roundness tolerance is 0.03, and the run-out tolerance of all diameters is 0.0127 on total length; Profile of tooth checks that rotation checks that lip surface has 2-3 ° of anterior angle on the ZOLLER detector, and special because of milling cutter tooth form, flute is again 5 ° of valleys, must process on SACKE numerical control relief-grinding bed so add man-hour.
Claims (2)
1. a valley profile milling cutter comprises taper shank, it is characterized in that: milling cutter is a bar type structure, has taper shank (1), and milling cutter chip area (2) is skewed slot, and lip surface has anterior angle.
2. valley profile milling cutter according to claim 1 is characterized in that: milling cutter chip area (2) is 5-30 ° of spiral goove, and the rake face anterior angle is 2～7 °.
