Abstract: A chip detangler is provided for a machine having a discharge trough for collecting fluid containing metal chips. An auger disposed along a longitudinal axis of the trough advances the fluid and chips downstream through an exit area. The detangler preferably comprises a snagging bar fixed relative to the machine and disposed at least partially within the trough to engage nests of chips traveling past the snagging bar. The forces induced by the auger tears apart nests engaged with the snagging bar into smaller, more suitable sizes.

Abstract: The present invention provides a filtering apparatus generally comprising a reservoir containing a pool of dirty fluid, the reservoir defined at least in part by a pair of laterally spaced side walls. A drum is rotatably supported within the reservoir, the drum having a generally cylindrical body having a first end, a second end, and an opening therebetween to pass fluid. A filter element is connected to the drum body and covers the opening to filter fluid flowing into the drum. The drum body is journalled about its outer surface to the reservoir for rotation therein. As such, the drum does not require any end walls to support the drum, and the entire end of the drum is wide open to the flow of fluid, which increases the rate of flow through the filter, and permits the filter to be used with a wide range of fluid flows. Unique adjustment of the drum is also provided.

Abstract: A separator with a continuously rotating magnetic drum which is partially disposed in a liquid flow path to attract and thereby separate magnetic particles from liquid delivered to the flow path. The separator includes an inclined scraper blade which removes the magnetic particles from the drum. The magnetic field of the drum penetrates the inclined scraper blade causing particles to build up on the blade, thereby allowing coolant which was carried with the particles on the drum to drain back to the flow path. A pushing force caused by particles subsequently delivered to the scraper blade by the rotating drum shoves the buildup of particles past the magnetic field acting on the scraper blade and down a discharge chute into a waste container.

Abstract: Burrs formed at the ends of a bore during a honing operation performed by a single pass honing tool are removed by a deburring attachment which is carried on the leading end of the tool. The attachment includes one set of spring-loaded blades which remove burrs at one end of the bore as the tool is retracted from the bore and further includes an axially spaced set of spring-loaded blades which remove burrs at the opposite end of the bore during retraction of the tool.

Abstract: A filter drum with a tubular filter belt is journaled for rotation on a pipe which serves to supply filtered coolant to spray nozzles located within the drum and operable to backwash the filter belt.

Abstract: Individual machine tools are supplied with coolant by individual filtration units which separate metal chips from the coolant in order to provide a clean supply to the machine tool. A central vacuum unit is capable of sucking chips from all of the filtration units and delivering the chip to a central processing area for disposal or salvage. To enable chips of different metals to be separated and salvaged, the vacuum unit is capable of discharging its output to a selected one of a plurality of hoppers in the central processing area. In order to further increase the flexibility and salvageability of the overall system, a plurality of vacuum units may be associated with the filter units, with any given vacuum unit being operable to selectively serve any given filter unit and capable of being selectively served by any given hopper.
