Mayfran Chip and Coolant Handling

Mayfran’s pneumatic chip / swarf conveyors provide for cost-effective collection of scrap from machining operations and transport to a central binning or processing operation.  Available in blowing- or suction-based designs, pneumatic chip conveyors offer reduced labor costs, improved cleanliness, and significantly increased uptime versus manual chip removal activities.  The systems are flexible enough to meet a wide variety of machine tool arrangements, including innovative at-the-tool design for large gantry-type machine tools.

The Vacuum Dynamics^® system is configurable with manual or automatic pick-up stations to serve multiple machine tools.  This cost-effective system is particularly well suited for cleaning up around large, open mills, and the overhead piping system provides flexibility for changes in layout or expansion.

Power-Trof® The versatile Power-Trof® trough-type conveyor effectively conveys loose or bundled metal chips, fines, curls, turnings and strings, as well as coolant, over short or long distances. It can economically handle large or small quantities of swarf.

An efficient series of one-piece, cast iron plows, mounted on a round steel shaft and pushed by a hydraulic cylinder, transports material through the trough by means of reciprocating action. Double-lined trough walls are available where required to avoid coolant leakage.

Power-Trof push bar conveyors are designed for smooth, trouble-free operation, easy installation and maintenance, plus maximum durability for longer service life.

Steel belt conveyors are best suited for low coolant content and bushy or broken chips.  Pitch sizes of 2.5” (63mm), 4” (100mm), 6” (150mm), and 9” (225mm) are typically used for chip handling, depending on expected load.  Special designs incorporating dimples, perforations, and reinforcements are available to suit more demanding applications.

Screw conveyors are best for metering the chip load into processing equipment, and can handle fine or broken chips as well as bundles up to ~12” (300mm).  Multiple screws are possible for higher chip loads and larger bundles.
