Cutter blade characteristics such as material, design, and thickness can hav e a large ef fect on cut quality . Blade materials Blue tempered spring steel is most commonly used because of its cost and av ailability ov er a wide range of thicknesses (0.010-0.062 inch). It is a very tough material with an HRC v alue of approximately 48-51 and fair we[...]

Blade Design Straight-edge knives have a straight cutting surf ace. A chop- ping action (which has cutting forces parallel to the cut) is typically obtained with straight-edge blades. Because the blade is mounted on a rotary arm, some slicing action (which has additional force vectors at v arious angles to the cutting edge) is obtained, but general[...]

Blade thic kness Because material is displaced rather than remov ed in rotary knife cutting, think of the blade as a wedge. The thick er the blade, the greater the displacement. This displacement can cause fracture in rigid profiles and tubing, which is often observed as a whitening on all or a portion of the cut. Y ou can reduce this fracturing by[...]

UGE059/1003 A LL A BOUT C UTTER B USHINGS A PPENDIX C-1 Rotary knife cutter bushings are probably the most ignored aspect of cutting. Y et, they are probably the most important ingredient to obtaining clean, square, accurate cuts with mini- mal jamming and broken blades. This appendix contains information about se veral aspects of cutter bushings: [...]

Supporti ve b ushings become more important if heat is used to minimize whitening (fracturing). ● If you are cutting a square or rectangular profile, whether rigid or flexible, a round b ushing bore will not offer proper support and will often lead to an "S" shaped cut. A flat bottomed bushing will of fer excellent support and enhance t[...]

A PPENDIX C-3 Cutter b ushing shear surface quality Similar to a dull pair of scissors, if the cutter bushing shear surface is not sharp the tube or prof ile is not supported to the side of the blade and the cut will not be clean. In some cases, the entrance of the do wnstream cutter bushing is slightly radiused to minimize jamming. While this prac[...]

Cutter b ushing length On flexible extrudates , it is important to minimize the length of the cutter bushings. It is v ery diff icult to push flexible extrudates through since it tends to compress as it is pushed, causing a marginal increase in the tube diameter . For this rea- son, bushing lubrication may be necessary to minimize drag as the lengt[...]

Adjusting the cutter b ushing gap If the bushing gap is too big, material is dragged do wn between the bushings creating a b urr , especially with flexibles. This may lead to jamming within the bushings where the upstream side of the cut extrudate actually hits against the do wnstream bushing surf ace. This is especially apparent with flexibles wit[...]

Blade and bushing lubrication can nearly al ways improv e the quality of cutting. Description of the cutting pr ocess Unlike sa wing, a rotary knife cutter displaces material rather than removing it. When the knife blade first contacts the extrudate, it pushes it against the opposite side of the cutter bushings. If there is too much clearance the e[...]

Common cutting lubricants Commonly used general purpose lubricants include: ● T ap water ● Dish washing liquid (Joy , etc) ● Glycol (anti-freeze, coolant) ● W ater-soluble silicone cutting oils ● Diesel fuel ● Mold release ● Mineral oil Medical grade lubricants: ● Distilled water ● Isopropanol (isopropyl alcohol) ● Mixtures of i[...]

If the blade has a rough surface where the e xtrudate rubs against it, material will accumulate on the blade in a cheese grater fashion. This scratched material will also be passed from the blade to the next cut and be seen as hairs or flak es. Some of the more flexible materials, such as silicones, soft urethanes and flexible PVCs, also e xhibit d[...]
