+ | ====Recommended blade selection and speed==== | ||
+ | In general, we want at least three cutting teeth to be in contact with the material being cut. So thinner materials require a finer tooth blade than thick materials. Please see lab staff for instruction on changing blades. | ||
+ | |||
+ | The bandsaw motor connects to the blade drive via a two speed belt drive. The belt must be in the low range for cutting stainless steel and titanium. All other materials may be cut with the belt in high range. The controller has 4 material categories pre-programmed: | ||
+ | |||
+ | Wood: | ||
+ | * Resaw: 4000/2160 | ||
+ | * Bowl blank: 3000/1620 | ||
+ | * **Rip/ | ||
+ | * Scroll pattern: 2000/1000 | ||
+ | |||
+ | Metal: | ||
+ | * Carbon steel: 250/135 | ||
+ | * Stainless steel: 100/100 | ||
+ | * Titanium: 75/75 | ||
+ | * Cast iron: 160/100 | ||
+ | |||
+ | Non-ferrous metals: | ||
+ | * Aluminum: 400/215 | ||
+ | * Brass: 250/135 | ||
+ | * Bronze: 220/115 | ||
+ | * Copper: 200/105 | ||
+ | |||
+ | Plastic: | ||
+ | * Acrylic: 2500/1350 | ||
+ | * Nylon: 1500/810 | ||
+ | * HDPE: 2000/1080 | ||
+ | * Custom: 2000/1080 | ||
+ | |||
+ | The speed adjust dial on the controller is used to adjust the speed up and down from these preset levels. If the saw is making a lot of noise, try lowering the speed. | ||
