Coolants & Lubrication Systems

The Grinding Doc: Using a wheel with too large of a grit size and dressing dull likely the cause of OD burn—not bad cooling.

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.

VOMAT (which stands for Vogtländische Maschinen- und Anlagentechnik) has made a name for itself in the metalworking industry with its individually tailored filtration systems for coolants, along with their stable cooling in the tool grinding industry and other processes. VOMAT's product portfolio includes modular solutions for individual systems, central systems and customer-specific special systems with central and decentralised functions. VOMAT provides systems for carbide and HSS applications but also for other materials such as cermet, ceramics and diamond.

This additive manufacturing process is helping machine shops create parts with complex internal cooling channels.

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.

The Grinding Doc addresses the cause of barber pole lines in workpieces.

Should we continue with classic machining and coolant lubricants, or do dry machining and minimum quantity lubrication (MQL) represent viable alternatives? From a technology point of view, it is important to consider material properties and machine performance, but plant costs, energy and health aspects increasingly need to be included in any assessment of the overall process. Lubrication system manufacturers and scientists commented on these aspects in the first of this two-part series. Part 2 now looks at various machining technologies from the practical perspective of tool and machine manufacturers: a preview of EMO Hannover 2019.

Production managers in manufacturing often have to ask themselves: should we continue with conventional machining and coolant lubricants, or do dry machining or minimum quantity lubrication (MQL) represent viable alternatives? Several factors influence this decision. In Part 1 of this two-part series of technical articles being published in the run-up to EMO Hannover 2019, lubrication system experts and scientists give their assessment. Tool and machine manufacturers shed light on the subject in the second part.
