More information on Near Dry Machining
While machine coolants have traditionally been used almost exclusively in machining and metal cutting operations, the concept of minimum-quantity lubrication has been steadily gaining momentum during the last several years.
MQL, also known as near dry machining, dry machining or near dry which replaces machining coolant with a minute amount of high-efficiency lubricant applied precisely to the cutting tool/workpiece interface. The spray lubrication systems have proven effective for machining all nonferrous metals and most grades of steel.
The most common lubricants for this process are biodegradable vegetable oil of which the Unist Coolube products belong too. This product is derived from cosmetic grade raw materials, which, because of their polarity, are known for their extensive friction-reducing properties.
Unlike mineral-based and synthetic fluids, vegetable based fluids are developed in the presence of oxygen, which causes them to organize and align better as they bond with the surface of metals, providing superior lubricity. These fluids, when properly applied,via a mist, oil mist or spray lubrication system significantly reduce the friction and corresponding heat created when cut metal before breaking off and becoming a chip.
Reducing that friction not only extends tool life, can increase feed rate and cutting speeds but also eliminates the need for cooling the tool with flood coolant. Additionally, the amount of fluid used is often less than 80ml per shift, which is either consumed in the cut or remains as a light film on the part and chips.
Changing from Alucabond/Composite panel to Solid Aluminium Sheet
Do you find yourself having to Route 3mm solid Aluminium sheet in preference to Alucabond/Composite panel? If you are experiencing any of the following you need to talk to our John Barker (Managing Director) of Unist Australia.
- Ragged cutting
- Burning out cutters
- Breaking router bits
- Terrible surface finish
- Just the inability to get the job done
We understand your problem, you need to lubricate the routing cutter with our 3 nozzle Coolubricator.
For help on this matter call John Barker on 02 8850 2022 or email [email protected].
