To determine this (you might need to break out the calculator), simply multiply the recommended cutting speed by the value 3.82 (round up to 4), and then divide by the tool diameter. For example, the ridiculously priced All Season 235/55R19 tires are a smidge over 29 inches in diameter, so that would mean (3.82 x 1320 SFM)/29.2 = 173 rpm.

coating costs are lower, but it will depend on the switch-over cost, the queue time and the idle time involved in the product mix of the sheet metal supplier. • Overhead Overhead, also called SG&A (Sales, General & Administrative), costs are the costs required to run the business. Typically these are spread out over every item shipped

## Cylindrical Grinding Calculator

Jun 10, 2015· Adjust the legs so that the tool rests are at the same height as your lathe's tool rest. Grinding wheels. Both sides of my grinder are outfitted with 80-grit Norton 3x wheels. I find that these wheels remove material quickly and produce an edge that I can use without additional honing. A 6ʺ wheel runs around \$45; an 8ʺ wheel costs \$55.

## The great grinding divide | Cutting Tool Engineering

Or, sometimes tools are thrown away before their time. To maximize the value of tools, consider using software packages like TDM Systems that help to optimize tool usage and tool life. How about taking a fresh look at regrinds, which can restore a cutting tool to almost brand new, and at a cost that is about 50% of a new replacement?
