  Robsin Bandsaw Blades
                 Custom Made
Bandsaw Blades can be made to any length required. Supply details of Length, Width, T.P.I. and material required and we will manufacture within three days.
Range includes – band knife available in different types.
– Straight blade for cutting soft fibrous materials such as foam, corrugated cardboard, fibreglass insulation, leather, felt, cork.
– Wavy blade for cellulose sponge bread, cake, rubber seals.
– Scallop blade for same materials as wavy, providing a faster cut but coarser finish.

 Most machines have a reasonable adjustment length, and stock sizes are more economical.

to length;
2) The weld is produced by way of Induction
Current and Upsetting Pressure;
3) The weld is then surface ground to ensure
a smooth, consistent thickness;
4) The weld is annealed in a purpose built
annealing machine;
The weld on our custom made blades is guaranteed.

  As a rule it is always best to use a blade with maximum possible width, since heavier feeding can then be used, due to the improved beam strength of the wider blade. On the other hand, the thickness is limited to the diameter of the wheels of the bandsaw machine.
Too small a diameter of the wheels in relation to the band’s thickness will cause band breakage.
INSTALLATION OF BANDSAW BLADES
Place the blade on the wheels and adjust to normal running position. Adjust the tension of the blade. Incorrect blade tension will result in great waste of blades. If possible use a tension gauge.
Most machine manufacturers will recommend the proper tension for their machines. The bandsaw machine should be adjusted to the blade. The wheels should be aligned with the blade guides for proper tracking of the blade. It is very important that the guides and the rear bearings are kept in good condition and should be replaced as soon as they are worn. Make sure that your wire brush (or equivalent) is in good working condition for cleaning of the tooth gullet.
