+ | Detailed Procedure: | ||
+ | |||
+ | Supplies: | ||
+ | * Bandsaw blades are kept in the cabinet of the Bandsaw stand. Notify the lab staff by emailing bothman@ucsb.edu if you break a bandsaw blade. The lab staff will replace it. | ||
+ | * Resaw bar assembly is kept in the cabinet of the bandsaw stand. Use this to prevent the bandsaw blade from walking and moving during the cut. | ||
+ | |||
+ | ====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: | ||
+ | |||
+ | |||
+ | 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. | ||
