Coolants & Lubrication Systems

HPT nozzles expand the working pressure range to a maximum 1,000 psi, allowing a higher level of machining while providing the same Loc-Line quality end users come to expect. The CT (compact turret) is for tight spaces and the XR (extended rotation) is also available.

With the ever increasing demand to position and hold more weight and higher pressures, Loc-Line introduces its ¾" element clamps. The ¾" system has been used to successfully deliver large amounts of fluid, hold heavy objects and large shields.

Vortec cold air guns use vortex tube technology and filtered compressed air to produce sub-freezing air as low as -30 deg F (-34 deg C) for numerous industrial spot cooling applications. With no moving parts to wear out, cold air guns require no electricity at the target, just a compressed air source.

Transor Filter USA offers a line of central oil filtration systems for tool and cutter grinders. The units can be expanded by adding a filter module that consists of three filter vessels, filter pump and plumbing. Model V9 can service up to 10 grinders, and the system can incorporate three additional machines by adding a module. The systems filter to a 1µm level, control oil temperature and automate sludge handling.

The SS mighty mini is ideal for removing oil from machining centers and parts washers. The portable unit can service multiple parts washers and coolant sumps, avoiding the expense of multiple units. The belt picks up the oil, which is then scraped from both sides by dual wiper blades at a rate of up to 2 gph (7.6 lph).

Italy-based Samputensili S.p.A. unveiled a machine that eliminates the need for cutting oils when manufacturing gears, thereby reducing grinding costs. During grinding, oil-based lubricants cool the workpiece, as well as reduce friction and help evacuate chips. On the downside, however, oil use accounts for a significant amount of a grinding operation's total cost. Expensive equipment is required to supply, chill, catch and wash away oil in grinding processes. In addition, Samputensili estimates that oil-treatment equipment accounts for 75 percent of the energy consumed by a grinding machine.

Filtration system manufacturer Vomat, Treuen, Germany, supports grinding operations with sophisticated fine filtration technology that contributes to the overall process of producing high quality tools economically, according to a recent news release from oelheld U.S. Inc. When it comes to the filtration of metal coolants, oelheld cautioned tool manufacturers not compromise.

Walter has introduced Walter Turn Precision Coolant, a powerful and targeted coolant delivery system that produces a direct coolant supply through the insert clamp and along the flank face of the insert. The result is said to be a 30- to 150-percent increase in tool life (depending on material and coolant pressure) for stainless materials, high temperature alloys and steels.

Productive Times challenge: Effectively clean and cool grinding oil applied in latest-generation grinders. The solution: A filtration and chiller system that directly communicates with grinding machines.

Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, offers his take on the effectiveness of scrubber nozzles. nAbout the Grinding Doc Video Series: Thanks to his work as an independent grinding consultant and the author of the "Ask the Grinding Doc" column in Cutting Tool Engineering magazine, Dr. Jeffrey Badger routinely receives questions about grinding from shops all over the world. Through the magazine column and this video series, he provides shops with the insight and guidance they seek.

The right filtration system in a tool grinding operation is an important part of the value chain and a prerequisite for high quality and uninterrupted production. Fine filtration systems developed by Vomat Inc., distributed by oelheld U.S. Inc., grow thanks to the availability of a variety of add-on modules to individually configure and tailor systems.
