Union PR 200/250 Floor Type Boring Mill

When your workpieces are too large to move to the spindle, then bring the spindle to them. The UNION P and PR Series machines are "Floor type" configurations that allow mounting of your workpieces to a fixed table and moving the machine spindle around your part with a traveling column X movement and traveling column or RAM style Z movement. This configuration is essential for large, bulky components that are too big or too heavy to fixture on a moving table. The traveling column design combined with automatically latched angle heads allow access to 5 sides of any workpiece mounted in front of the spindle. Using a floor plate supported by your foundation, part weight is only limited by your ability to move it to the machine. Workpiece size is limited to about 16 feet up and down but virtually unlimited in length.

PR 200

Not only is the P and PR Series the answer for large bulky parts but also a great solution for the flexible needs of a job shop environment that may change part size and volume requirements overnight. When your not using the large machining envelope of this machine, create different "work zones" on the table that allow multiple set ups and "pendulum machining" that keeps the spindle cutting without downtime due to part loading and unloading.
