Hot Stuff: High-Speed Milling And Heat Generation

Posted on: 27 March 2020

Mills have a particular problem: If you run them a lot, you risk making them generate a lot of heat. That makes sense, as metal grinding against metal, especially if it's milling something that's rather tough, will produce friction and thus heat up. But the heat can be very damaging for the equipment and the materials being milled—and it can create problems for your workers, too, no matter how much safety gear they wear. You need to get a mill that generates as little heat as possible, such as a Quadro, if you want to produce milled products that don't show the effects of excess heating.

Heat May Affect Particle Quality

Depending on what you're trying to mill, the heat generated from the friction between the mill's parts and the milled material could affect the quality of the material. Heat-sensitive items could melt and smear, rather than just being milled into smaller pieces. the material could stick together instead, or the chemical properties of the material could change as the heat essentially cooks the material. That could make the end product useless to customers.

Generated Heat Is Uncomfortable for Workers

The amount of heat generated can become very uncomfortable to deal with over the course of a day. Not only can workers feel a lot hotter—something that increased air conditioning can combat only up to a point—but the heat could transfer to the metal parts of the mill and create a burn risk. Your workers must wear safety gear around the machines, of course, but that gear also contributes to feeling hot after a while. The less heat a mill produces, the better, even in winter.

The Mill Itself Could Overheat

There is also the risk of the mill itself overheating. All that heat goes somewhere, and a lot of it transfers into the metal and spreads. The motor running the mill can produce heat, too, and all that heat combines to make operating temperatures soar out of control. If the mill doesn't have an efficient system for heat dispersal, you could damage the mill easily.

A mill like the 197 MIll Quadro Comil that produces little heat (or minimal heat, depending on conditions) is best. These make work a lot more comfortable for your workers, make things safer for everyone, and help ensure the best quality milled material as possible. Lots of models and cone sizes exist, which means you should be able to find a mill that is perfect for your company.
