The Rikon 14” bandsaw with StriaTech variable speed motor is located in 2448 Elings.
Serious injury and potential dismemberment can occur from contact with the moving saw blade.
Eye injuries can result from flying chips or broken bits. Cuts can occur from contacting sharp
tools or exposed chips and burrs. Burns can result from hot cutting tools or parts. Metal splinters
can result from exposed burrs or chips. Serious injury can result from pinching or entanglement
in moving parts. Poor housekeeping creates tripping and cutting hazards for other users. Do not
leave machine running unattended.
Eye protection, closed toe shoes, long pants, and protective clothing must be worn when using this machine to prevent injury. Long hair must be tied back and jewelry must be removed before operating this machine to prevent entanglement.
Take and pass the Machine Shop Safety test found on the ME Labs GauchoSpace page, read the Drill Press document on the Innovation Workshop GauchoSpace page, attend the Innovation Workshop general machine tool training, and the Innovation Workshop Bandsaw specific training before using this machine. Additional documents found on the GauchoSpace page.
Sequence of Operation:
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, metal, non-ferrous metals and plastic. Within each category 4 materials are programmed. These preset speeds are listed below. The speeds are listed in two units (sfm/rpm): surface feet per minute (sfm)/ and revolutions per minute (rpm). The conversion factor between sfm and rpm changes with the position of the belt on the drive pulley.
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.
Sources for Supplies:
General rule of thumb for TPI: always at a minimum have 3 teeth worth of engagement in your material at a time.
|Aluminum||24 TPI @ 1 mm, <10 TPI @ > 6 mm||1000 FPM|
|Steel (low carbon)||20 TPI @ 3 mm, <14 TPI @ > 6.5 mm||<250 FPM|
|Steel (stainless/Chromoly/High carbon)||28 TPI @ 1 mm, <14 TPI @ > 6 mm||<125 FPM|
|Plastic||24 TPI @ 1 mm, <10 TPI @ > 6 mm||2500 FPM|
|Wood||24 TPI @ 1 mm, <10 TPI @ > 6 mm||4000 FPM|
