ATST
Automatic Torsion Spring Tester

Custom Interchangeable Tooling

Using LSI’s custom interchangeable tooling technique, you can machine tooling blanks to fit your specific applications or send the information to us and we will do the work for you.

• Achieve 30 second tool-less changeovers from type to type
• Identical setups each time enhance repeatability
• Pre-machined blanks make tooling inexpensive and standardized
• Tooling can be designed to exactly match assembly features for best correlation
• Built-in angle zeroing provides ± 0.1° setup accuracy every time
• The best solution for repeating parts or specific spring types or families

Universal Tooling

With the universal tooling supplied by LSI, you can test many parts with no special fittings. This is great for unique or one-time job runs with a minimum of setup time.

• 2″, 3″ & 4″ universal fittings
• A conventional approach that has good flexibility in making setups
• Includes chuck, mandrill set to 17/32″ diameter and reaction plate

Rapid Changeovers

Both custom and universal tooling is designed to be changed in seconds… YES! In just seconds, you can go from one setup to the next, maintaining your repeatability and reproducibility. Setups within ± 0.1°.

Smart Interchangeable Torque Cartridges

Switch from one torque cartridge to another in just minutes, allowing for a single tester to test a wide range of capacities quickly and accurately. Smart torque cartridges can be digitally calibrated. You can also send in only the smart torque cartridge to LSI for remote calibration (full system calibration is better than individual component calibration).

Delicate lower-capacity torque cartridges feature overload-preventing lockout mechanisms

Z-Axis Control

Crank Z-Axis the control to desired length for specific length compression testing.
Available on our ATST 200, ATST 500 and ATST 1300 standard base units for both high and low profile models.
