Metalworking Fluid Eases Magnesium Machining
Magnesium is widely recognised for its favourable strength-to-weight ratio & eminent suitability for casting. it is seldom used in pure form for structural elements & is generally alloyed for the production of parts for the automotive, aerospace & electronic sectors. magnesium alloys are amongst the easiest of the structural metals to machine.
Although magnesium alloys are easy to machine, the technique requires careful management & this metalworking liquid extends sump life & avoidsresidue build-up
they require the least power of any commonly machined metal, for example, 50% less than aluminium alloys & 90% less than nickel & cobalt based super alloys.
Indeed they can be shaped & fabricated by most metalworking processes & are easily welded.
it is not all 'plain sailing' however as a subcontractor to a major magnesium die-caster can confirm.
Although it agrees that magnesium alloys are easy to machine, the technique requires careful management.
Inappropriate choice of metalworking liquid can cause a number of production problems & for this particular subcontractor these included short sump life, residue build-up & inefficient pump-out & recharge.
The odour of the liquid also prompted a lot of operator complaints so health & safety was an issue .
With these prevailing problems the company was keen to trial the new dedicated coolant developed by Master Chemical, TRIM E737.
it's been developed as a cost competitive product that's compatible with virtually all magnesium alloys up to 4000 ppm.
it's been formulated to provide exceptionally tidy jogging & to maintain tool sharpness for optimal cutting.
The results were impressive.
The product's extreme hard water tolerance also had a positive effect in this regard.
As TRIM E737 virtually eliminates hydrogen generation, the residue build-up the subcontractor had been experiencing with its previous water-based liquid disappeared immediately.
As a result machines became cleaner allowing easier part changes & maintenance.
The excellent bio-stability of TRIM E737 proved over the length of the trial to provide a long sump life without the require for any additive.
Complaints about the smell of the product were eliminated & coolant disposal costs were cut by a substantial 40%.
'By changing to TRIM E737 they have reduced our operating costs per machine,' confirmed a company spokesman.
'This product is affordable, effective & has helped reduce production costs for a significant part of our business.'
