Paste & Fluid
Most important wear aspects
Wear is a surface phenomenon that occurs by the displacement and detachment of material. Because wear implies a loss of weight over a period of time, it generally differs from breakage, fractures and plastic deformation.
THE FOUR BASIC WEAR MECHANISMS:
• Adhesive wear
• Abrasive wear
• Tribochemical interactions
• Fatigue (Surface fatigue)
THE EFFECTS OF THE TRIBOLOGICAL INTERACTIONS:
• Friction
• Wear
• Surface quality loss
WEAR-SOCA SYSTEM PROPERTY THE TRIBOLOGICAL SYSTEM:
THESE PRODUCTS (HTP AND HTF) HAVE ALREADY IN PRACTICE THEIR INFLUENCE ON THE TOOL LIFE, BUT IT IS ALSO POSSIBLE TO FRICTIONDRILL DRY IN SOME SITUATIONS.
WEAR-SOCA SYSTEM PROPERTY THE TRIBOLOGICAL SYSTEM:
To reduce or eliminate the above mentioned adhesive wear, the friction drilling process can be done using the Drabus frictiondrill paste HTP or -fluid HTF. The HTP is a paste that is composed of a fixed lubricant and a mineral oil. HTF is a fluid mixture composed of the same components as the paste, but it can also be used as a spray.
During the frictiondrilling process, both the HTP and HTF products produce a fixed grease- and dividing film which is high pressure resistant. The dividing and lubricating properties are maintained within the temperature range from -20°C to +1150°C. The mineral oil evaporates at high temperature, so there is no or only a small remainder left on the workpiece.
How to use these lubricants? How to order?
HTP:
Bring a thin film of the paste with a small brush to the surface of the Drabus frictiondrill. On a CNC-machine, the Drabus frictiondrill can be programmed to automatically dip into the paste, between two frictiondrill operations.
HTF:
The fluid can be applied with a spray or haze system.
Drabus was established in 1980, and designs, manufactures and sells friction drills for mass production of threaded connections.
