working with delrin and teflon. tips on good finishing? :,for delrin i always use standard aluminum tools, coolant, high rpm. for something like your part i'd use a two-flute 16mm end mill, 8000rpm, 1200mm/min. it might not be a mirror finish, but it's really smooth, not fuzzy or anything. sanding would only make it worse. same with teflon. i don't like teflon, it's a bit too flexible for my liking..end mills - kyocera-sgstool.com,the new z-carb hpr five flute roughing end mills are ideal for achieving high metal removal rates (mrr) and a finish of 80 rms or better on most materials. the specialized five flute design is engineered for increased productivity over three and four flute end mills..angle & dovetail end mills | shopmws,keo (29) micro 100 (6) ttc production (60) whitney tool (42) home. metal cutting tools: high speed steel & solid carbide. end mills. angle & dovetail end mills. showing 1-24 of 137..osg | taps | end mills | drills | indexable | composite,exocarb® wxs-cre end mills: list 4472 - exocarb® wxs-cre (inch) list 4572 - exocarb® wxs-cre (metric) the series offers the following features and benefits: provides advanced productivity with spiral flute design; radius end mill for high feed machining; ideal for stainless steel and titanium as well as cast iron; effective up to 65 hrc steel.

choosing the correct angle end mill for your job helix angles generally come as low as 12° to as high as 60°. most general purpose end mills use between a 25° and 30° angle where basic sharpness and cutting edge strength is maintained. increasing the helix angle improves stock removal and is useful in machining at increased speeds and feeds.
wally, you'll run out of rpm on your bp before anything else machining teflon. with a good sharp cutter, you can probably run 400-600 sfm. just start out like it was aluminum. the stuff machines good except for the burr it leaves. i like to deburr with a good, sharp, 3 sided knife.
the coatings that have become the most popular are the tiain- or altin-coated end mills. they are much more effective effective at dissipating heat than the tin coatings from 20 years ago. the heat is dissipated so well into the chips with the altin coating that dry machining is mostly recommended, except when slotting where the chips need to be expelled out of the channel.
no other cutting mill is easier to clean then the 911mpecm2500 & 911mpecm4000 cutting mills. when the grinding process is finished the grinding chamber is fully accessible by unscrewing two hand screws and folding back of the infeed hopper.
drill, tap and put a piece of aluminum on the end. then leave the end mill, sharp (new) four or two flute, i'd try the four flute first, at the bottom of the slot you cut into the fixture and feed the lengths of pvc by hand in to the fixture, hit the stop remove and repeat. if you have a good grip with two hands on the pvc, it isn't going to rotate.
uncoated 2 and 3 flute high helix solid carbide is good for non-cooled light cutting in aluminum. zirconium nitride is a great coating for carbide end mills used in non-ferrous applications, if you can get it. the number of different types of end mill that are best for a specific application is mind boggling. there's no one 'best'.
convential milling should be used and feed per tooth should be reduced by 50% please note: the above recommendations should be considered only as a starting point; 'fine tuning' may be required in order to maximize performance 96
a feature on a variety of high performance end mills, variable helix, or variable pitch, geometry is a subtle alteration to standard end mill geometry. this geometrical feature ensures that the time intervals between cutting edge contact with the workpiece are
the end-mill tool 100 illustrated in fig. 1a has two cutting edges 114 and 116 at the point 104. the number and location of the cutting edges 114 and 116 is determined by the flutes 110 and 112. fig. 1b shows the cutting edges 114 and 116 of the tool 100 in greater detail.
