Rotary cutting machines

Some examples of rotary cutting machines are the following Fabricated-Steel Rotary Knife Cutter (Sprout, Waldron Co) Giant Dicing Cutter (Taylor, Stiles Co) Mikro-Chipper (Pulverizing Machinery Co) and others by Paul O.Abbe Engrg C°. Hollander Jordan beaters for pulping NC may also be classed with these cutters... 

Finally the tow is finished with oil and cut with a rotary cutting machine. The cut fibres fall into a collecting tunnel from where they are either mechanically or pneumatically conveyed to the baler. 

In some size-reduction problems the feed stoeks are too tenacious or too resilient to be broken by compression, impact, or attrition, In other problems the feed must be reduced to particles of fixed dimensions. These requirements are met by devices that cut, chop, or tear the feed into a product with the desired characteristics. The sawtoothed crushers mentioned above do much of their work in this way. True cutting machines include rotary knife cutters and granulators. These devices find application in a variety of processes but are especially well adapted to size-reduction problems in the manufacture of rubber and plastics. They are finding important applications in recycling paper and plastic materials. ... 

Heuristic 51 Particle-size enlargement. Use compression with rotary compression machines to convert powders and granules into tablets of up to 1.5 inches in diameter. Use extruders with cutters to make pellets and wafers from pastes and melts. Use roll compactors to produce sheets from finely divided materials the sheets are then cut into any desired shape. Use rotating drum granulators and rotary disk granulators with binders to produce particles in the size range of 2 to 25 mm. 

The milling machine has a rotary cutting drum equipped with replaceable cutting teeth or tools and a front-loading conveyor to load the milled material onto the truck. 

A specific type of development machine which cuts the rock by the use of a rotary cutting head on the end of a boom. As with all development machines, it also has the capability to gather debris, pass it through the machine and off-load at the rear. 

Almost all remaining machine work, including all small parts, can be done on a metal cutting lathe. All holes can be drilled with a drill press. A rotary indexing table for the drill press is not essential, but it simplifies locating the various holes in the fuze body in proper relation to each other. (90 and 40 from reference lines). 

A first notch of 250 micrometers radius at the tip was mill cut with a rotary cutter. In order to prevent heating while machining, specimens were cooled with fresh compressed air during cutting. A sharp notch was further introduced at the tip of the first notch with a razor blade. The displacement of the razor blade was controlled by a micrometric thrust so that slow and careful control of the blade advance could be monitored. Figure 3 shows the device used to machine the sharp notches automatically in order to improve reproducibility. 

Bursters from the mortars and projectiles are fed into the BWMs by a pick-and-place machine and processed in the BWMs to wash out aU explosives (Parsons, 2000c). There is one BWM in each ECR (total of two). The BWM has a rotary carousel with multiple receptacles. Bursters are aligned with a multinozzle water-jet washout probe on the BWM so that the jet cuts into the explosive charge axially from the open end. The water jet, which contains no abrasive, is injected at about 12,000 psi, although lower pressures of 2,000 to 3,000 psi are being considered. When the jet reaches the end of the burste tube, the water-jet probe is withdrawn. The washed burster tubes are discharged from the BWM one at a time onto a conveyor for transport to a container-loading station in the parts transfer area and then conveyed to the batch MPT for 5X decontamination.
