Measure your gasket thickness
[MEJ01]
The MEJ01 was designed to ease the measurement of the indented gaskets thicknesses.
There is no risk of deforming the gaskets with the steel points.
Mechanical features: – Resolution: 0,001 mm – 0.00005” – Mechanical aperture 6.35mm – 1/4” – XY setting of the lower point. – Interchangeable conical points. – Conical point tip size: Ø 0.50 mm – External sizes: W= 65mm. D=120mm. H=190mm.
Others features: – Switchable mm/inch. – Zero setting. – Setting limits and values. – Digital Display, analogical mode and high resolution. – Full-screen LCD. – Auto-off.

MDAC Washer

Compensation washers are used for the union between the membranes and the MDAC.
They are offered in several thicknesses to compensate the deformation of the membrane and are available in several materials
MDAC Washer for RT — MDAC Washer for RT 3,3mm — MDAC Washer for HT


Guidance Dowel
[901 –]
The BETSA® design uses 4 Guidance dowels per DAC. They guide the movement on the Z axis with extreme precision.
BETSA® offers Guidance dowels in different alloys depending on the experience environment.
It is possible to make thermal and surface treatments to improve the operating conditions.
Guidance dowel in treated steel, high temperature inconel or Beryllium copper, of different length and Ø, with anti-oxidation, thermal or tefloning treatment. This is all that BETSA® offers for these MDACs.
The quality of rectification 1-3µm of these guidance dowels can lead, depending on the case, to an aid in disassembly after high temperatures or to obtain an accuracy of 0.1µm.
Other size on demande

Extractor
[EX –]
Extractors are simple and effective tools essential for separating the piston from the cylinder of MDAC BETSA®.
The tight fit of dowels guigances and high temperatures may cause them to require assistance in unblocking.
Made of extra hard plastic, the extractors allow parts to be separated without leaving a mark.

Pump
[PUMP01]
If BETSA uses a pump to remove the dielectric liquid in the tank of the drill EDM [MH20M], it is for 2 reasons.
The 1st is that the tank contains a few milliliters of electric oil, this amount of oil is quite large for contain the EDM dust drilling. The dusts does not focus around the drilled hole and then it is to be disseminated throughout the whole liquid which minimizes the concentration of dust and increases the quality of the sparks.
The second is to remove the liquid without using absorbent papers and to have your fingers full of it.
