CH-300SA Automatic Metal Cutting Band Saw (300mm, Mitre to 60°) | DDM Machinery, Shanghai, China

The CH-300SA is an automatic metal cutting band saw for cutting bar, tube, and section. It cuts at 90° and can swivel automatically to make mitre cuts at 45° and 60°. Cutting capacity at 90° is 300mm for round material and 360mm wide by 300mm high for rectangular material.

The saw frame is fed hydraulically along a chrome-plated column guide, and is slightly inclined, which DDM says improves cutting performance and extends service life. Workpieces are held by dual hydraulic clamping in an automatic-feed hydraulic vise. Blade speed is infinitely variable from 20 to 80m/min using an inverter, and the machine has NC control.

It comes fitted with an automatic chip conveyor, blade cleaning brush, working light, a saw frame height selector gauge, and one bi-metal saw blade, along with a set of tools in a tool box.

Why Choose an Automatic Mitring Band Saw?

Fabrication shops cut a lot of bar and profile to length and to angle. An automatic saw with hydraulic feed and clamping does this without the operator standing over the machine, and mitre capability avoids a second machine for angled cuts.

• Mitre cutting. 45° and 60° cuts as well as 90°.
• Automatic operation. Hydraulic feed, clamping, swivelling, and chip removal.
• Adjustable speed. Infinitely variable blade speed from 20 to 80m/min to suit the material.
• Solid frame guidance. Hydraulic feed along chrome-plated column guides.
• Ready to run. Chip conveyor, blade brush, light, and a blade come as standard.
