The DWS.250 type diamond wire saw is currently our largest two-way vertical table saw.

The maximum workpiece cutting area is 250x250 mm and the recommended diamond wire thickness is 0.20 to 0.50 mm. The continuously adjustable wire speed goes from 0 to 4 m/s. To ensure a constant cutting pressure, the feed is done by gravity. Workpieces can be cut both wet and dry.

The DWS.250 is equipped with an operator-guided, ergonomically visible touch control. There is currently a choice of six languages (DE-EN-FR-ES-JP-CN). The industrial-grade drive and control technology ensures robust and precise operation. The built-in sensor system for end of cut, open hood or, if necessary, wire breakage ensures safety. The precision saw is made of stainless steel and anodized aluminum.

On the slot table of the DWS.250 your workpieces can be fixed flexibly with our offered clamping devices.

 Cutting fluid 

This cutting fluid is a concentrate without hazardous substances and biodegradable. An addition of 3-5% in the water avoids the corroding of the sample to be machined, e.g. made of steel, and prevents the material abrasion from sticking to the diamond wire. The liquid is filled in a transparent 1 liter plastic bottle.
