The Trim VHP E820 is a minimal foam cutting and grinding fluid concentrate which, even at pressures greater than 150 bar and when diluted with soft water, doesn't foam. According to the manufacturer, this is important for several reasons.

Foam can compromise production and even bring it to a halt. Competitive products require a conventional defoamer to overcome this major drawback but this is an added expense, an additional procedure and its use can also result in filter blockages. Trim VHP E820 is claimed to be a cleaner, safer and more economical alternative.

The stable, high performance product has been formulated by Master Chemical Europe in the UK, specifically to meet the requirements of EU manufacturers and contains no chlorine, sulphur, boron or formaldehyde donors. Trim VHP E820 is therefore particularly suited to the production of aerospace parts - a benefit that is confirmed by Pratt & Whitney approval.

The fluid is ideal for operations that use high pressure, high volume coolant. It maximises the benefits of through the tool coolant delivery systems on vertical and horizontal machining centres and will help achieve high productivity levels from creep feed and VIPER grinders.

This clean emulsion reduces carry off for low total operating cost and permits fast wetting for excellent lubrication and corrosion protection of the workpiece.

Compatible with all metals and many non metallic materials, the coolant can run at lower concentrations for higher speed operations, where heat removal is a key issue. Higher concentrations are recommended on soft materials and for lower speed operations where friction and reduction and control of built-up edge are critical.

For many years Master Chemical Europe has supplied carbide tooling manufacturers with its Trim C120CG water-based metalworking fluid. Now, with the introduction of a new neat grinding oil for carbide, the company is able to provide a comprehensive grinding product package for this sector. The new Trim OG108 is formulated to meet the requirements of all carbide and HSS tool grinding operations.

Trim OG108 is a high quality product that uses a refined hydro-cracked base oil to ensure high flash point and very low levels of mist. The low viscosity oil provides excellent detergency, keeping grinding wheels clean and allowing chips to be efficiently flushed away from the process. This, together with efficient workpiece cooling ensures minimal burning throughout the grinding process. Kind to machine components, wheel bonding elastomers and operators, the fluid is chlorine and sulphur-free, water clear in appearance and is virtually odourless. The oil does not leach cobalt and has good oxidation stability giving it a long and stable service life. Trim OG108 is available in 204 litre drums, 1,000 litre IBCs or in bulk quantities.
Another characteristic of the new introduction is its excellent filterability and to maximise potential in this regard Master Chemical also offers its Clean Tower mobile filtration system. This compact and inexpensive product is able to purify Trim OG108 down to 3µm.
