The ENESKArecoat 85 carbide coating system operates according to the principle of electro-dis-
charge machining. A carbide electrode is attached to the positive pole of a DC circuit. It is made
to vibrate in the Vib85 application handpiece. The workpiece is connected to the negative pole.
During the brief contact pulse between the workpiece and the electrode, the electrode is briefly
overheated by the flowing current to such an extent that, during the discharge, carbide particles
from the electrode are entrained and fuse to the workpiece surface.

Fitting/changing the electrode
The choice of electrode depends on the size and shape of the surface to be coated. Workpieces
with simple shapes can be coated with a 1.6 or 2.1mm square electrode. Dies with complicated
internal shapes or small holes are coated with the appropriate round, 3-sided or 4-sided elec-
trode. For small holes of less than Ø 1.2mm, the round 1mm electrode is ground at least 0.2mm
thinner than the hole to be coated on a diamond or silicon grinding wheel.
Caution!
To avoid injuries caused by the hot surface of the tool, only connect or change tools when the
control unit is switched o.
Caution!
To avoid injury from tools coming loose, always tighten the tools carefully and regularly check the
fit of the tool.
Attention!
To avoid damage to the components,
• thoroughly clean all parts before installing them and
• use only the screwdriver supplied.

Operation
Attention!
The workpiece must be metallically clean and bright. It must not have any scaling or other
impurities, as the coating will then not be reliably absorbed and will not adhere securely.
The magnet must also always be clean to ensure good electrical contact.
Attention!
Before each use of the unit, check that all contact connections are clean and tight.
Degrease perfectly bright steel surfaces well before coating.
Pretreating surfaces
Coating can only be successful if the coating is applied to a metallically clean steel surface.
The following methods can be used to clean the workpiece:
• Fine blasting: achieves the deepest diusion of the tungsten carbide molecules in the base
material and the highest adhesion of the coating.
• Grinding: grind over the contour to be coated or at least clean it with abrasive cloth or diamond
files and then degrease it.
Do not use acidic cleaning agents! These do not neutralize suciently, continue to act under the
coating and can destroy the coating.

To avoid damage to tools or the workpiece:
• always start with the standard setting (vibration intensity 60% and charging voltage 48V) and
then adjust both as required and
• for high power settings, only use tools designed for this purpose!
The following parameters can be set with the “PAR1” button:
»Coating energy: 30–54V
»Vibration intensity: 0–100%

The following parameters can be set with the “PAR2” button:
»Operating mode
Operation with 1 cylinder or with 2 cylinders; the setting depends on the electrode thickness
and the desired coating strength.
»Application type
SMOOTH/ROUGH
With the “ROUGH” selection, the ignition point for the discharge current occurs before or
while the electrode is touching the workpiece. As a result, the drops are mechanically
separated and the surface is coated more roughly.
With the “SMOOTH” selection, the ignition for the discharge takes place shortly after the
electrode leaves the workpiece again. The surface is coated more smoothly.
»Phi_0:
This parameter cannot be changed.
If a value is displayed, it is the correction value between the electrical and mechanical ignition
timing.
NOCAL indicates that no calibration is taking place or has taken place.
»Interval
0.5–30 seconds; intervals are used for short, repetitive coating operations. One second
corresponds to 120 strokes.
»Int-Pause
0–20s; pause between intervals.

Calibration
The mechanical zero point depends on various factors and varies according to energy and
vibration intensity, diameter and length of the electrode as well as pressure of the electrode and
guide angle to the workpiece.
Always adjust the mechanical zero point at the start of work, after changing settings, and as
needed.

Processing the workpiece
Attention!
To avoid injuries, do not touch the metal part of the handpiece, the clamping element or the
electrode while working!

Hold the handpiece with one hand and support your hand as much as possible. Press the
electrode lightly against the workpiece at an angle of 15–20° to the surface to be coated.
If the electrode touches the opposite edge in this inclined position in the case of small holes or
profiles, you can also hold the electrode parallel to the hole.
Process the surface of the workpiece slowly and evenly until the coating is as fine and homoge-
neous as possible. An optimum coating is matt grey and fine-pored.
Caution!
Under continuous operation and with a strong energy output, the electrode becomes warmer
than 42°C and its holder heats up. This then leads to a slow heating of the entire handpiece.
• If the handpiece becomes too warm, switch o the handpiece and allow it to cool down.
• For continuous operation, work alternately with two handpieces.
Attention!
If the electrode glows, the coating becomes defective. Sparking also leads to a poor result, as
the melted carbide splatters and cannot be deposited on the workpiece.
• If the clamped electrode starts to glow or sparks fly, reduce the coating energy.
In the case of very fine moulded parts, coating in stages is advantageous because it can some-

what dampen the fusion penetration on exposed areas.
If a finely lapped surface is to be achieved, you should first apply a relatively thick coat, followed
by a thinner second coat.

Polishing the coating (if necessary)
Wet the applied coating with abrasive file oil. Then smooth the applied coating with a dia-
mond-tipped tool in rotating movements. Next, clean the coating with a cleaning agent
(JOKE X 73016 ).
To obtain a very fine surface, polish the coating further with a wooden stick and a 20μm diamond
lapping paste. Clean the surface. Then polish the coating further with a wooden stick and a 10μm
diamond lapping paste. Machine round workpieces as described on a high-speed rotating lathe.
