Now, maybe for this hobbyist the wear has not yet become an issue. The head is quiet, the quill binds a bit but that's OK, the back gears are quiet and all the machine functions seem to work OK. I have a hunch there are many of us in the same position. What are you doing about the wear? When I tighten up the locking screw the table tightens up ...
Micro-milling yields small accurate parts quickly for electromechanical, aerospace, and medical applications.

Measuring the working end of a new carbide end mill with a manual micrometer is a great way to ruin it. Cutting tools cost real money and no one wants to toss not used up after a easy job run. When an end mill comes out we use a good loupe or stereoscope to classify it. Blue marker is good but used, red marker ok as a rougher.
The paper discusses how the measurements might influence and enhance approaches to energy and wear efficient mill operation when compared with current day modelling techniques. Insights are drawn from measurement inside two operating SAG mills in Australia using sensors inserted into grinding media and sensors fixed to the rotating …
FARSENSE SAG is designed to be attached to the rotating drum of a Semi-Autogenous Grinding (SAG) mill and measure the wear of the liner in real-time using EMAT sensors and instrumentation and a patented technique. The EMAT sensors are attached to the bolts holding the SAG mill liner and send measurements to a base station at regular intervals ...
