Coolants & Lubrication Systems

Because through-coolant toolholders eliminate the variances often experienced with external cooling nozzles, the additional cost of such holders, which is sometimes zero, can be easily justified through the reduction of cycle times and improvement of tool life and part quality.

AirForge 4028 is a newly developed protective lubricant for hot forging of steel and alloys. It delivers outstanding results when metal protection against oxidation, gas diffusion and heat is required.

Wayne Products releases the Mini-Skimmer R.S., a belt-type oil skimmer that collects over a quart of oil per hour despite its tiny housing that measures just 3"x3"x2.75". Designed as an easy-to-use solution for small machine shops, Mini-Skimmer R.S. skims unwanted tramp oils from coolants, but can rest easily with the flip of a switch once its job is complete.

A circular shape provides multiple benefits in the machining world. For example, round inserts are stronger than inserts with any other shape. However, when it comes to coolant channels in cutting tools and toolholders, channels that don't have circular cross sections can enhance operations.

The Quaker Chemical Corp., Conshohocken, Penn., acquired Lubricor Inc., a Canadian metalworking fluids manufacturer, in a deal announced Dec. 1. Lubricor, which manufactures and markets value-added metalworking products such as synthetic and semi-synthetic coolants, hydroforming fluid, and stamping products, sells directly to primarily Tier 1 and Tier 2 automotive suppliers in North American, according to a Quaker news release.

Klüber Lubrication has introduced Klübersynth GE 4 80 W 140, a fully synthetic high-performance gear oil based on polyalphaolefin (PAO) that offers high stability and protection even under shock loads. With Klübersynth GE 4 80 W 140, Klüber Lubrication complements its range of efficient high-performance oils for railway gears.

Autofiltrex, the latest addition to Eclipse Magnetics' range of magnetic filtration systems, is a fully automated sub-micron filtration device designed to ensure ultra-polished fluids on a 24/7 basis.

The metalworking fluids commonly applied during machining processes generate airborne mists that must be carefully controlled.

Machine tool users wouldn't benefit from through-spindle coolant (TSC) without rotary unions, which bring together spinning and stationary components to improve coolant delivery.

5ME recently acquired 51 patents in four patent families from Creare, an innovator in cryogenic systems and fluid dynamics. The acquisition gives 5ME control of the intellectual property related to cryogenic machining – specifically, the process of transmitting liquid nitrogen at -321° F through the spindle/turret and tool body, directly to a cutting tool's edge.

Throughout the sometimes-contentious world of machining, the debate rages about whether to apply flood coolant or cut dry. As in many areas of machining, the choice is not easy and requires careful and informed consideration. To further complicate the decision, minimum-quantity lubrication (MQL) can be a successful compromise that provides an efficient and effective answer to the troublesome question.
