1.. IntroductionAs coarse grained, easily processed ore bodies are depleted, more disseminated, fine-grained ores are being treated. Adequate liberation of valuable components within a fine-grained ore is often only achieved once the particle size of the ore has been reduced to levels below the traditional ball mill cut-off of 45. μm.. To aid in the …

I had this brilliant idea (?) that I could put a grinding wheel on my horizontal mill and do tool grinding, kind of. I'm thinking that with a spindexer to set angles and the 3-axis feed, I could do precision grinding, or semi-precision anyhow. For instance, grinding broaches for a rotary broach. The biggest limitation that I see is the arbor speed.

The entire point of most grinding operations is to create a high-quality surface finish, but shops may not have finer-grit wheels to try if their surfaces end up too rough. Increasing the wheel speed and shallower cuts is the most common solution, but when you are already running max rpms, you will need to find other methods for …
Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
