  • What lubricants do you need for a screw machine?
  • For example, a screw machine requires a dual- or tri-purpose lubricants due to cross-contamination. Lube and cutting oils can come into contact with each other during the machining process, so a specialty oil is needed to counteract this. Dual and trig-purpose oils can be used in hydraulics, lube boxes, and oil sumps.
  • Why do mills use heavier oil?
  • Mills often use the heavier oil because of the vertical ways-you want maximum cling time to those vertical dovetails. The lathe oils are typically ISO 68 weight. My mill uses ISO 220 weight which I think used to be called Vactra #4. (Vactra is still made, but the formula has changed to reduce the tacifiers so its less sticky.
  • Do metalworking machines need lubricants?
  • Getting into more specifics, metalworking machines require different types of oils as well. For example, a screw machine requires a dual- or tri-purpose lubricants due to cross-contamination. Lube and cutting oils can come into contact with each other during the machining process, so a specialty oil is needed to counteract this.
  • How much oil can be extracted from an oil mill?
  • Usually the mechanical pressing method provides yields of only 65-70% of the oil, and 80% is considered very good. Most large commercial operations use a mild pressing operation to extract 60 to 70% of the oil, while the remainder is solvent-extracted.
