Ritmo SIGMA PRO Bandsaws
The SIGMA PRO series are electric workshop band saw machines for plastic pipes (HDPE, PP, PPR, PVC) and sheets.

The SIGMA 400 PRO and 630 PRO are provided with special spherical bearing guides allowing ease of sideway movement. The equipment includes a control panel for automatic operation of the arch saw (in/out) and adjustment and regulation of the cutting speed. These machines can be used in conjunction with an optional kit to cut plastic sheet, consisting of a supporting bench and adjustable sheet guide square.

The SIGMA 1200 PRO and 1600 PRO are specially designed to perform easy cuts with a wide range of angles (-45° to +67.5°). They include a PLC system, allowing the operator to input the exact cutting angles with the highest precision.
