A well-run precision maintenance and training program will have a major impact on maximizing the service life of rotating equipment. For example, at the core of most rotating equipment is a bearing. An accepted rule of thumb is that 99.5% of all bearings do not achieve their useful life. Bearing life is impacted by the way it was …
It's the Rotomill, a simple three-axis CNC machine, with a rotary axis, that just about anyone can build. The design of the Rotomill uses a standard, off-the-shelf Makita rotary tool for the ...
Chronic hemodialysis only dates back to the 1940s. Before there was dialysis, chronic kidney disease was fatal. With the advent of the Kolff Rotating Drum dialysis machine in 1943, a new era of treatment for kidney failure began—which has saved hundreds of thousands of lives. Here, we share a brief history of dialysis from its start to the present.
Rotating motion can be dangerous; even smooth, slowly rotating shafts can grip hair and clothing, and through minor contact force the hand and arm into a dangerous position. Injuries due to contact with rotating parts …
This is the first rewarding step to building your roto cast machine. The first steps are to drill holes in preparation for the threaded rods. You will need to drill a series of 4 holes on the 18x18 inch 1x1 frame, and 2 holes in the 16x16 inch frame. All the holes for the 18x18 frame should be drilled in the exact centers of each side.
