Description

PCD High Speed Milling Operation blade

Technical field

The utility model relates to superhard cutter, relates in particular to high speed, efficient, high life cutter blade.

Background technology

Hyundai Motor alloy component and computer aluminum alloy spare part Milling Process, need at a high speed high accuracy, high life, high economy, and low-carbon environment-friendly, common cutter can't be competent at, so need the research cutter material, cutter parameters, cutting parameter, wear principle, the polycrystalline diamond PCD High Speed Milling Operation blade of the extraordinary parameter of special design research and development.

The utility model content

The purpose of this utility model is to provide and meets the high speed that Hyundai Motor aluminum alloy spare part and computer aluminum alloy spare part Milling Process are used, and is high-accuracy, the PCD High Speed Milling Operation blade that the high life requires.

PCD High Speed Milling Operation blade is characterized in that, blade relief is 15 °, the blade nose angle is 85 °, and tool arc is 3mm, and the blade side rake angle is 5 °, 3 ° of back rake angles, wiper edges length is 1mm, the drift angle is 20 ' and, blade thickness is of a size of 3.97 ± 0.02mm, the blade aperture diameter is 4.4mm, blade width is 9.495 ± 0.02mm, and blade lengths is 9.555 ± 0.01mm, and cutter head is the polycrystalline diamond cutter head.

The beneficial effects of the utility model are:

1. polycrystalline diamond (PCD) material, high wearability, corrosion resistance, impact resistance can adapt to the high-speed, high precision processing of silicon-aluminum containing alloy part and very high durability is arranged also more carefully.

2. the PCD rake face of 5 ° of compound anterior angles and 3 ° has good cutting chip removal function and good machined material rheology antifriction characteristic is arranged, and this is for reducing cutting force, improve tool life highly significant, can use by the transposition clamping simultaneously, improve economy, practicality.

3. 15 ° of relief angles of blade are less for aluminum alloy materials Milling Process frictional force, cut brisk and durability to improve intensity better, tool arc R3 can experience a shock again by moulding, nose angle can make for 85 ° installs 5 ° of back auxiliary angles, can keep cutting edge strength and cutting resistance less, can not strengthen cutting resistance again, it also is important cutter parameters, the good raising surface quality effect in more important wiper edges length 1 and drift angle 20 ' have, hole φ 4.4 can use by M4 screw clamping, also firm stable, globality and stability when blade width 9.495 ± 0.02 and blade lengths 9.555 ± 0.01 can guarantee the blade unit use, the dimensional accuracy of cutter is the basic demand of cutter level, consider economy and reasonability when also necessity need be considered, be suitably, promptly under the prerequisite that guarantees processing request, design suitable tool precision requirement.
