Coolant Delivery Systems

The TungTurn-Jet system strategically directs the internal coolant jet exactly where it is needed, close to the cutting point on the insert rake face. This dramatically improves chip control during the machining of difficult-to-cut materials, which is not the case with conventional coolant delivery methods.

EXAIR's new 1/8 NPT no drip internal mix air atomizing spray nozzles mix liquid and air inside the nozzle and produce a fine atomization of liquids. The new, patented no drip internal mix air atomizing spray nozzles work in the same way the company's standard atomizing nozzles do, but have the added benefit of positively stopping liquid flow when compressed air is shut off.

EXAIR's new 1/8 NPT siphon-fed spray nozzles atomize fluids in a range of spray patterns for a wide variety of uses. These are the company's smallest air atomizing nozzles and are suitable for tight spaces.

The need for energy-efficient, sustainable processes is increasing especially with regard to the frictions caused by high energy prices, increasing global warming and scarce resources. These requirements also have a direct impact on vacuum systems, which are an elementary component in heat treatment plants and metallurgical processes.

New additions to JETI (Jetstream Integrated) tooling from Seco Tools eliminate coolant-through tooling and connector interference that hinders grooving, parting-off and other turning operations. With interference-free internal coolant capabilities and the option to switch the underside stream channel on and off as required, these expansions to the range of MDT (Multiple-Directional Turning) X4 (grooving and parting-off) and 150.10 (parting-off) toolholders add operational stability and reliability while they improve surface finishes.

EXAIR's new 1/8 NPT small internal mix spray nozzles atomize fluids up to 42 gallons per hour. Internal mix atomizing nozzles mix the liquid and air inside the cap and produce the finest atomization. Internal mix nozzles can be used on liquids with a viscosity up to 300 centipoise.

What is the main purpose for coolant application? Of course, among many reasons, primarily it's for the lubrication and cooling of the cutting edge and, in addition, to help facilitate chip evacuation. REGO-FIX has launched a cost-effective and efficient attachment for the application of coolant-lubrication liquids through the tool, based on an ER collet nut, which is suitable for use on SUHNER feed drilling units.

Plant engineers can now choose one CIRCOR coolant pump to handle pump outlet pressure needs from 0 to 100 bar. The Allweiler EMTEC-C three-screw coolant pump introduced last year handles even higher pressure applications than before, increases overall speed and efficiency, and offers manufacturers one simplified pump suitable for keeping abrasive machine chips, particles and heat away from cutting surfaces in machine tool coolant service.

The new VARODRY is a 100 percent oil-free, dry compressing screw vacuum pump. Screw pumps are currently state-of-the-art in the field of industrial vacuum pumps. The VARODRY will initially be available in the sizes VD65 (65 m³/h) and VD100 (100 m³/h), the sizes VD160 and VD200 are already in preparation.

When grinding tools, ultrafine coolant filtration is clearly a worthwhile proposition for the tool manufacturer or regrinder: The cleaner the grinding oil is and the less often it has to be replaced, the more it will save on coolant costs, minimize waste, and reduce tool costs and machine downtimes.

AMCOL Corp. introduces electronic control and PLC (Programable Logic Controller) integration to its 6000 series precision lubrication systems for true minimum quantity lubrication (MQL). MQL incorporates extremely accurate spray equipment to place minute amounts of concentrated lubricants to the cutting tool/workpiece interface to maximize tool life and provide a near dry environment.

When processes are based on a permanent vacuum, the choice of suitable components is all the more important. Reliable, high-performance vacuum technology not only does the job; the working environment also benefits from more peace, less distraction and higher air quality. These factors of ergonomics significantly increase the general well-being.
