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.
Wear-solidity is a system property.
The tribological system
:

|
- Basic body
- Opposite body
- Interspace material
- Environment medium | -
Relative movement
- Contact temperature
- Normal force |
| The effects
of the tribological interactions:
- Friction
- Wear
- Surface quality loss
The
four basic wear mechanisms :
- Adhesive
wear
- Abrasive wear
- Tribochemical interactions
- Fatigue (Surface fatigue)

| Lubricant paste or fluid.
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.
| 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. |
How to use these lubricants
?
| 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 friction drill 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. |
