MQL company sets up in UK; launches new product

German producer of automated lubrication systems, Bielomatik, has opened a UK office in St Neots Cambridgeshire and launched a new minimal quantity lubrication (MQL) system.

MQL technology allows semi-dry (or near dry) machining operations to be carried out with only a minimal amount of lubrication (as low as 10ml per hour) to prevent tool damage. And unlike conventional water-based cutting fluids (emulsions), minimal quantity lubrication uses waterless lubricants. It is far more effective and gives a finish which is the same, or better than wet machining.

Recent trials have shown MQL to cut a total cycle time by 30 per cent, giving greater productivity; equivalent to cutting a typical hourly rate of £50 to under £35 per hour.

The new system is a highly-efficient two-channel design, where oil and air are delivered separately to the tool holder before being mixed and sent to the cutting tool.

Spindle speeds of up 40,000 rpm can be supported as centrifugal forces through the spindle do not affect the delivery of the oil, as with other types of MQL. Also by allowing the use of higher viscosity oils, it gives better lubrication for longer tool life, thus an inherent reduction in service and maintenance of the cutting machine. It also enables quick tool changes to take place due to its minimal switch on/off time of only 0.1s.
