Precision Master Plates
  • Universal quick change system for any chuck
  • Reduce set up and changeover times by up to 80%
  • Eliminate out of round conditions and concentricity problems
  • Repeatability < 0.001" TIR
When it comes to turning/holding smaller diameter parts Abbott’s precision master plate and segment system is an ideal choice for high changeover and short running jobs. Due to the system’s high repeatability, it is an excellent alternative to more expensive quick change chucks. The system consists of an aluminum master plate, similar to a thin Pie Jaw®, which is bored and bushed to accommodate Abbott’s standard, off-the-shelf pinned segments. Plates are available in 8, 10 and 12 inch diameters and can be mounted on 4-12 inch diameter chucks. The master plate can be custom machined to fit any model chuck, making it a permanent universal fixture on any machine.

When using this system, the transition from one job to the next simply requires bolting on a new size or configuration of segments before continuing with the next production run. For repeat jobs, machine operators can designate job specific tooling, allowing them to setup in minutes by using pre-machined segments from a previous run. The master plate and segment system maximizes flexibility between machines because segments can be used to run jobs on any machine that has been fitted with a master plate, regardless of machine or chuck type.
