Abstract
The invention relates to a blind groove diamond coating milling cutter. The milling cutter has a fishtail-shaped structure, and comprises a milling cutter head, a scrap discharging groove and a handle, wherein the head cutting edge of the milling cutter head is inclined to the center; the scrap discharging groove is integrally formed in the back cutter surface of the milling cutter; a helical angle is formed outside the scrap discharging groove; the handle is arranged on the back part of the scrap discharging groove and is connected with the main shaft of a PCB (printed circuit board) drilling and milling machine; an HFCVD (hot filament chemical vapor deposition) diamond coating is deposed on the surface of the milling cutter. Compared with the prior art, the blind groove diamond coating milling cutter has the advantages of wide machining range, high production efficiency, long service life and the like.
Description
Technical field
The present invention relates to a kind of milling cutter, especially relate to a kind of blind slot diamond coatings milling cutter.
Background technology
Severity control milling plate, these technique great majority only there will be on high laminate and backboard product, and PCB milling cutter is the cutting tool in milling profile (moulding) process.By the profile of tooth difference of milling cutter, can be divided into helical tooth cutter, rhombus tooth milling cutter, fish tail type and apex point type milling cutter, plain cutter exists lower cutter severity control inaccurate, cannot the flat blind slot of milling and exist tool wear serious.Because different tip-type shapes show that effect is also variant, its area of cut is large, from telling with bad at an easy rate in appearance, so in severity control milling plate, most important be will be to milling cutter tip shape selection.
Summary of the invention
Object of the present invention is exactly in order to overcome the defect that above-mentioned prior art exists, to provide that a kind of range of work is wide, production efficiency is high, the blind slot diamond coatings milling cutter of long service life.
Object of the present invention can be achieved through the following technical solutions:
A diamond coatings milling cutter, this milling cutter comprises:
Milling cutter tip: fish tail type structure, head blade is to centroclinal, and it is smooth smooth that cutter head blade can effectively be controlled the bottom of flat blind slot;
Chip area: be wholely set on the rear knife face of milling cutter tip, the arranged outside helical angle of chip area, the helicla flute of large chip space makes chip removal smooth;
Shank: be arranged on the rear portion of chip area, for the main shaft of connection PCB drilling and milling machine;
The surface deposition HFCVD diamond coatings of milling cutter.
The angle of described helical angle is 15～25 °.
The diameter of described shank is 3.175mm.
Described HFCVD diamond coatings is diamond composite coating, and bottom is the diamond thin of deposition, and top layer is the nano diamond coating that original position continues hot-wire chemical deposition.The features such as the existing conventional coating adhesion of this coating is strong, wear-resisting, have again that nano diamond coating surfacing is smooth, coefficient of friction is little, without new features such as grinding and polishings, can be applied to high accuracy complicated shape blind slot milling cutter.
Compared with prior art, the milling cutter tip of blind slot diamond coatings milling cutter of the present invention guarantees that blind slot bottom is level and smooth, considers helicla flute to be worth doing improve chip removal effect by great Rong.Utilized the ultrahigh hardness of diamond coatings, higher high temperature resistant and wearability, these milling cutter tool wearing and tearing are reduced greatly, cutter life is extended.Specifically comprise following advantage:
(1) range of work is wide: can be used for processing all kinds of printed circuit board (PCB)s, comprise the metal substrates such as unmanageable aluminium base;
(2) production efficiency is high: due to high temperature resistant and wearability, can select higher cutting speed, thereby boost productivity, meanwhile, cutter life length is conducive to reduce the tool changing clamping time;
(3) machined surface quality is high: because tool wear is few, so machined surface roughness is low, groove milling, hole and edges of boards, surface be clean, neat, without burr;
(4) long service life: at the surface deposition HFCVD of milling cutter diamond coatings, the features such as the existing conventional coating adhesion of this coating is strong, wear-resisting, have again that nano diamond coating surfacing is smooth, coefficient of friction is little, without new features such as grinding and polishings, making cutter life is six times of plain cutter.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present invention;
Fig. 2 is left TV structure schematic diagram of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
A diamond coatings milling cutter, as shown in Figure 1-2, this milling cutter comprises milling cutter tip 1, chip area 2 and shank 3 to its structure.Milling cutter tip 1 is fish tail type structure, and head blade is to centroclinal, and it is smooth smooth that cutter head blade can effectively be controlled the bottom of flat blind slot.Chip area 2 is wholely set on the rear knife face of milling cutter tip 1, and the arranged outside angle of chip area is the helical angle of 15～25 °, and the helicla flute of large chip space makes chip removal smooth.Shank 3 is arranged on the rear portion of chip area 2, and for the main shaft of connection PCB drilling and milling machine, the diameter of shank 3 is 3.175mm.
At the surface deposition HFCVD of milling cutter diamond composite coating, bottom is the diamond thin of deposition, and top layer is the nano diamond coating that original position continues hot-wire chemical deposition.The features such as the existing conventional coating adhesion of this coating is strong, wear-resisting, have again that nano diamond coating surfacing is smooth, coefficient of friction is little, without new features such as grinding and polishings, can be applied to high accuracy complicated shape blind slot milling cutter.
