Master Plates
Abbott‘s master plate and segment system is a great choice for turning larger diameter work pieces. The system consists of an aluminum master plate, similar to a thin Pie Jaw®, which is machined and keyed to accommodate Abbott’s stock segment rings. Plates are available in various diameters from 15 to 48 inches and can be mounted on 8-48 inch diameter chucks, effectively increasing the holding capability of smaller 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.
Segments are available in specific ID/OD ranges, allowing machining time to be spent on making production parts instead of boring out excess jaw material. 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. In addition to reduced setup and tool preparation time the system enables material and shipping cost savings as well.
- Universal quick change system for any chuck
- Reduce setup and changeover times by up to 80%
- Ideal for machining larger diameter thin walled parts
- Eliminate out of round conditions and concentricity problems
- Effectively double the holding capacity of any chuck without eliminating the ability to hold small parts
Precision Master Plates
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 stock pinned segments. Plates are available in 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.
