MOUNTING CONFIGURATION FOR
±0015 ACCURACY

The Ball Lock Mounting System is designed to speed accurate locating and locking of fixture plates and subplates. The system consists of three parts: a Locating Shank, a Liner Bushing, and a Receiver Bushing. Using the Ball Lock Mounting System is a simple three step process. Install receiver bushings in your machine table or subplate, and liner

bushings in your fixture plate; then insert the locating shanks through the liners and into the receivers to provide accurate location. A couple of turns of the set screw in each of the locating shanks provides positive holding force. Eighteen locating shanks, two types of receiver bushings, and two types of liner bushings are available to suit your individual

requirements.
It is recommended that the use of the Ball Lock Mounting System for locating and clamping of fixture plates be incorporated in a systematic process. All fixture plates should have two locating points positioned as far apart as possible. There is no advantage to having more than two

locating points. If more than two flanged shanks are required to provide additional hold- down force, omit liner bushings in the additional holes in the fixture plate and allow .030 over the nominal size. The additional clearance will insure that these holes have no influence on the locating holes.

How Accurate Does Your Positioning Have to Be? The center distance of the receiver bushings in the machine table, tombstone, or subplate should be as accurate as possible (±.0002 recommended). Accurate location will insure a sound base for interchangeability of numerous fixture plates. For accurate repeatability

within .0005 of true position, both of the liner bushings in the fixture plate should be primary liners and the center distance tolerance should be ±.0002. For slightly less accurate repeatability (within .0015 of true position), use one primary and one secondary liner with a center distance tolerance of ±.001.
