Feeds & Speeds Calculators | Nachi America
If the option is available, tilting the spindle will lead to an increase in tool life with ball end mills. Always use caution and best judgement when applying updated speeds/feeds. Each individual application is different than the next. Rigidity of workpiece, tool holders, etc. may contribute to optimal feed rates.

Ball Mill
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

How Long Does an Elevator Last? Elevator Useful Life Calculator
Estimate how long your elevator will last with our Useful Life Calculator. Elevators are a significant investment, and it only makes sense to get as much use out of it as possible. In general, an elevator’s useful life lasts 20 to 25 years, but depending on the type of unit and other contributing factors, that estimate can be highly variable.
