The principle of MQL is highly efficient, the developers explain. An exact amount of oil is introduced into the cutting area of the tool. This results in an almost dry process and the heat generated is primarily dissipated via the chips. The improved one-channel-system increases the aerosol volume in the cooling channel and can now reportedly supply up to 80 ml/h of aerosol to the tool without accumulating oil. In the standard device, air pressure can be increased up to 16 bar. Moreover, the German exhibitors add, the automatic mode makes the system very user-friendly. It also contains an integrated control system with hardware and software interfaces for Profibus and Profinet. The four aerosol outlets enable the simultaneous supply of up to four spindles in a machine tool, which is said to provide an improved distribution of the lubricant. In addition, the programs can be set up for process optimization. The system utilizes an automatic refill unit, is capable of using different MQL oils, and is also suitable for deep-hole drilling as well as for small tools.
New one-channel system optimizes lubricant distribution
The minimum quantity lubrication (MQL) technology from Bielomatik promises reduced energy consumption, less water consumption and less oil-containing waste. The one-channel-system creates a stable aerosol that is guided through the spindle towards the tool via internal channels. The company says it has further developed and optimized this technology.
