Quick and Accurate Fixture Location
The Ball Lock® Mounting System provides a method of quickly and accurately locating fixtures onto machine tables. The Ball Lock® Mounting System has done for machining centers what the Japanese SMED concept did for presses. Instead of single minute exchange of dies, Ball Lock® provides single minute exchange of fixtures. Fixtures can often be exchanged in less than a minute and with position repeatability of +/-0.0005” (+/-0.013mm). Fixtures can be exchanged between different machines when both are using the Jergens Ball Lock® Mounting System.
Locate…Often Without Indicating!
The Ball Lock® System accurately positions your fixture plate with a repeatability
of +/-0.0005” (+/-0.013mm) or better, minimizing the need to indicate your fixture.
The Ball Lock® System securely holds fixture plates to subplates
with up to 20,000 lbs. (9000 kg.) of hold-down force per shank.
How accurate should positioning be?
The center distance of the receiver bushings in the machine table, tombstone or subplate should be as accurate as possible, +0.0002” (+0.005mm) recommended. Accurate location will assure interchangeability of numerous fixture plates. For accurate repeatability within +/-0.0005” (+/-0.013mm) of true position, both liner bushings in the fixture plate should be primary liners and the center distance tolerance should be +0.0002” (+0.005mm). For a slightly looser fit, repeatability within +/-0.0015” (+/-0.04mm) of true position, use one primary and one secondary liner with a center distance tolerance of +0.001” (+/-0.003mm).
