In modern manufacturing, even one tightening error can lead to defects, rework, or downtime. Verifying tool performance isn’t optional. It’s essential for compliance with ISO 9001, IATF 16949, and your own quality standards.
STbench makes testing easy, eliminates setup changes, and improves efficiency—so you can stay compliant, reduce risks, and deliver quality with confidence.
Whether you're in automotive, aerospace, or general industry, STbench gives you the control, compliance, and peace of mind you need to keep production moving and quality uncompromised.
Automatic Tool Calibration
STbench integrates seamlessly with Atlas Copco and competitor controllers, enabling real-time tool adjustments to maintain uninterrupted production—even during process deviations.
Trace Simulation
STbench simulates non-linear joints, allowing tightening tools to be tested under real-world operating conditions, improving accuracy and ensuring consistent performance on the production line.
Connectivity
With native OPC UA support, STbench seamlessly connects to QA Supervisor for robust traceability and securely integrates with your MES and quality systems using the industry's most trusted industrial communication protocol.
Routine and Notifications
STbench takes the guesswork out of inspection planning, leveraging upper-level software to automatically load the right inspection at the right time—while managing push notifications to keep your workflow seamless and your production line ready.
Analysis
When connected to QA Supervisor, STbench provides instant access to advanced analytics—including Gage R&R, capability studies, CAM/Cpk, CNOMO, and joint reports—to support smarter, faster quality decisions.
Norms Compliance
STbench includes built-in inspections that comply with ISO 6789-2:2017, ISO 5393, VDI/VDE 2645-2, and JJF 1610:2017—making it easy to test tools in full alignment with global industry standards.
Cut test complexity and downtime.
Designed for flexibility and efficiency, STbench supports all your tools on a single platform—eliminating setup changes and reducing test time. Discover our range of transducers that equip the bench for any application.
Direct Driven Tools
To effectively test Direct Driven tools, it's important to simulate both rotation and joints. Without joint simulation, only the motor's starting torque will be assessed, which can lead to unreliable results.
The Hydraulic Brake is the answer. It accurately replicates the joint characteristics through trace simulation, while improving testing efficiency eliminating the need of loosening bolts.
It is suitable for testing Direct Driven tools and various wrenches, complying with ISO 5393 – VDI/VDE 2645-2 standards.
Hydraulic brakes 2-500Nm
The torque precision of the Hydraulic Brake is:
±0.5% from 10% to 100% of the nominal torque capacity.
±1% from 5% to 10% of the nominal torque capacity.
Pulse Tools
Testing pulse tools, whether pneumatic or battery-powered, comes with specific challenges: they deliver torque with high-energy bursts (about 1 ms). And various factors such as socket mass, extensions, friction, and joint stiffness influence torque output.
The best approach to perform capability tests is to use a static transducer with a joint simulator on STbench.
SRTT-B 0.5-2000Nm
The torque accuracy of SRTT-B is:
±0.5% from 10% to 100% of nominal torque capacity.
±1% from 5% to 10%% of nominal torque capacity
Clutch Tools
Testing a clutch tool is essential to ensure it delivers the correct torque and functions reliably. Clutch tools tend to have higher RPMs compared to Direct Driven tools, that’s why a fast and reactive system is preferrable. STbench Hydraulic brake answers these needs.
Hydraulic brakes 2-500Nm
The torque accuracy of the Hydraulic brake is:
±0.5% from 10% to 100% of nominal torque capacity.
±1% from 5% to 10%% of nominal torque capacity
Wrenches
Testing procedures for Click, peak and Cam-over wrenches require a reliable method to accurately
detect Click point. Without proper detection, tests based solely on peak torque reflect the operator’s
skill rather than the tool's performance.
Atlas Copco’s equipment can automatically identify Click, peak and Cam-over points in its transducer
portfolio.
The updated ISO 6789:2017 standard imposes stricter requirements that are not achievable without the usage of motorized cell.
Motorized Cell 1 – 1600Nm
The torque accuracy of the Motorized Cell is:
±0.5% from 5% to 100% of nominal torque capacity.
±1% from 1% to 5% of nominal torque capacity.
Hydraulic Wrenches
Testing hydraulic torque wrenches is crucial for safety and reliability in critical areas like wind power and petrochemical plants. Torque output is adjusted via oil pressure according to the manufacturer's pressure/torque chart. Since hydraulic tightening is slow and nearly static, testing methods differ from those used for electric or pneumatic tools, making dynamic testing methods unsuitable. Custom solutions are available for higher torque capacities.
SRTT HWT 2500- 75.000Nm
The torque accuracy of the HWT dedicated SRTTs is:
±0.5% from 10% to 100% of nominal torque capacity.
±1% from 5% to 10%% of nominal torque capacity
