high-performance dielectric fluid Witol BTW for coated toolsand tungsten carbide

This new development, a water-based medium which contains proper additives, guarantees the manufacturing of reproducible and high-quality holes for electrode diametersof 0.2 mm.

Witol BTW is delivered ready-to-use. A dielectric aggregate (water treatment) is necessary, which is responsible for a good quality in cooperation with the mixedresin cartridge. The medium should be cooled as otherwise a steady performance cannot be reached.

Measuring device:
– conductivity meter conductance 170 µS/cm

Peripheral requirement:
– water treatment
– dielectric aggregate with filter and deionised resin absolutely necessary
– integrate the cooling coil into the cooling System
– recommended for reproducible quality
– good electrode quality

 

high-performance dielectric fluid Witol BT for normal steel, copper, brass  and some tungston carbides

Witol BT is a high-performance dielectric designed for economic and fast working starting with optimally an electrode Diameter of 0.2 mm. It is also suitable for the processing of aluminum. Work pieces made of ferrous metals are temporarily protected from corrosion. Witol BT is a ready-to-use product. The concentration is regulated by using a hand refractometer.

Measuring device:
– conductivity meter conductance 800 µS/cm

Peripheral requirement:
– water treatment
– dielectric aggregate with filter
– integrate the cooling coil into the cooling system
– recommended for reproducible quality (option)
– starting from 0.8 mm
