Lubricants and Coolants & Modifying Metals
Reducing can be done with extreme pressure lubricants at speeds over 7,000 FPM. There are many mills that run at very low speeds when reducing expensive alloys such as beryllium, copper, tantalum, and gold and use little or no lubricant or coolant. Many lubricants are good for extreme pressure, but they can also act as a coolant. Water is still considered one of the greatest liquid coolants. An extreme pressure lubricant mixed with water makes a good lubricant.

3-High Rolling Mill
Three-high rolling mills consist of a large back up roll, small work roll, and another large back up roll. The purpose is to have a very minimum amount of reduction. Three-high mills are commonly used for making bearing material for gasoline and diesel engines.

Mechanical Screwdowns & Roll Bend
Mechanical screwdowns are still used for small mill reducing and large mills for cogging and hot plate reducing where accuracy is not a precision factor, and where fire may be a concern. However, hydraulics can now be water hydraulics. By adding chemicals in the water, you have a hydraulic system that will not catch fire. However, water hydraulics require limited low pressure, and they are high in maintenance and many customers still prefer mechanical screwdowns

Dual Motor Drives & Housings
The main advantage of a dual motor drive is that each work roll is individually driven. If one roll gets damaged and needs to be ground down, the other roll does not have to be ground down to the same diameter. This allows each motor drive to compensate for the different diameters.
