2. mould milling cutter
Mould milling cutter is used at machining mould antrum or punch figuration surface. You Lixi knife evolves and mould milling cutter is become, if pursue,8-24 place is shown. Can divide the taper that it is a circle by working section appearance crop, cylindrical head of ball of ball head, conic form 3 kinds. Use of milling cutter of hard alloy mould is very extensive, divide but milling outside all sorts of moulds antrum, replaceable still hand clears with file and emery wheel wheelhead the Mao Bian of workpiece of casting, forge, solder, and undertake be rectifyinged solely machining waiting to certain figuration surface. This milling cutter can be installed use on pneumatic or dynamoelectric tool, manufacturing efficiency and durability increase number than emery wheel and file decuple.
2, milling machine clamping apparatus
The commonly used outfit that milling machines places a method
Milling treatment is plane, keyway, gear and the method of commonly used treatment of all sorts of figuration faces. When work is processed on milling machine, use the following kinds of methods that hold clip commonly:
(Clip of 1) direct outfit is large on milling machine workbench workpiece often installs clip to be on workbench directly, with impaction of snail column, pressing plate, this kind of method needs to use the dial gauge, relative position that delimits the tool such as the needle searchs to machining face and milling cutter, if pursue,8-25a place is shown.
(2) holds the medium, small-sized work with clip simple to appearance work with plain top vice with the machine tool, in can installing clip to use plain top vice in the machine tool commonly, if graph 8-25b place is shown, when using, need to assure vice the proper place in the machine tool.
(If graph 8-25c place is shown,3) places workpiece with dividing head outfit, graduated to need workpiece, can install clip to be on dividing head directly commonly. Additional, do not need graduated workpiece places treatment with dividing head outfit very convenient also.
(4) wears the workpiece that hold clip with V form this kind of method applies to an axis commonly kind spare parts, besides pair of neutral with be had better beyond, still can bear greater cutting power, if pursue,8-25d place is shown.
(5) places workpiece special fixture to locate accurate, clamp goes to the lavatory with special fixture outfit, efficiency is tall, apply to commonly group by group, mass-produced in.
Milling cutter is common knowledge of damaged of attaint of treatment problem milling cutter
Generally speaking, milling cutter has 8 kinds to wear away commonly form:
1. point wears away. Improve way: Raise feed; Lower cutting rate; Use more the bit material of wear-resisting is qualitative; Use coating razor blade.
2. collapse is broken. Improve way: The capable person with use nicer tenacity is qualitative; The razor blade of use point aggrandizement; Check the tigidity of machining complex; Increase tool cutting edge angle.
3. heat is out of shape. Improve way: Lower cutting rate; Reduce feed; Decrease cut deep; Use the capable person that has hot rigid more to pledge.
4. is cut in damaged. Improve way: Change tool cutting edge angle; Point aggrandizement; Change bit material is qualitative.
5. hot crack. Improve way: Use cooling fluid correctly; Lower cutting rate; Reduce feed; Use coating razor blade.
6. accumulates bits. Improve way: Raise cutting rate; Raise feed; Use coating razor blade or cermet razor blade; Use cooling fluid; Make point sharper.
7. crescent moon wears away depression. Improve way: Lower cutting rate; Reduce feed; Use coating razor blade or cermet razor blade; Use cooling fluid.
8. ruptures. Improve way: The capable person with use nicer tenacity pledges or groove; Reduce feed; Decrease cut deep; Check the tigidity of machining complex.
Attention: After normally knife face wears away when amounting to 0.7 millimeter, should change blade point; The biggest wear extent is 0.04 millimeter when finish machining.
