How can multi-spindles improve productivity in automated assembly applications?

Why adopt the MULTI in automotive industries?

In industries like automotive manufacturing, synchronized tightening is essential to ensure quality, safety, and efficiency. Whether assembling structural components, battery modules, or safety-critical systems, the ability to apply torque simultaneously across multiple fasteners is key to avoiding deformation, ensuring uniform clamping force, and maintaining product integrity.

The Desoutter MULTI is a game-changer in this space. It:

• enables synchronous tightening,
• ensures precise torque application
• protects operators from high-voltage risks.

This is especially valuable in battery module assembly, where maintaining uniform clamping force is crucial to prevent settling and warping.

For suppliers working closely with car manufacturers, the MULTI helps deliver finished or near-finished products that meet the industry’s exacting standards.

What about simultaneous tightening in general industries?

By performing multiple operations simultaneously, multi-spindle tools can lower the cost per part to improve competitiveness and reduce cycle times significantly.

Introducing multi-spindles can also:

• reduce changeover times,
• free up valuable floor space,
• improve energy efficiency compared to running several single-spindle machines
• scale easily as production demand increases

When integrated with production software, the MULTI can be quickly reconfigured for different tightening operations, improving flexibility and enabling manufacturers to respond rapidly to changing market demands.

In case of failure on the system, the MULTI can identify precisely which component needs to be replaced. It takes just 30 seconds to rebalance the system, minimising downtime.

How, as an integrator, can I benefit from the MULTI?

Integrators face constant pressure to deliver faster, more reliable, and more adaptable automation solutions. Their end customers demand ever-shorter cycle times, consistent quality, and equipment that can be easily reconfigured for evolving production needs.

The very compact footprint of the MULTI:

• reduces the number of cables required
• allows the equipment to be positioned closer to the product.

This not only frees up valuable production space but also reduces the risk of cable-related failures, a common issue in traditional multi-spindle setups. This simplified design makes integration easier.

In addition, the MULTI is designed to customize your fixed spindles as modular units, simplifying the overall machine installation by reducing the number of individual components required.

As these examples illustrate, the Desoutter MULTI multi-spindle solution delivers benefits for machine tool builders and end-users alike.

Powered by 400V, MULTI systems allow for higher spindle speeds and reach very high torque, accelerating the tightening process.

Their modular design, featuring interchangeable components, boosts uptime by enabling quick and easy fault resolution.

This flexibility:

• minimizes production interruptions
• and supports continuous operation.

The MULTI's extra compact size allows it to be installed directly onto the machine, ensuring minimal impact on the workstation's footprint.

It uses the same CONNECT platform as other Desoutter battery tools, allowing for seamless management of all assets.

When integrated with higher-level control systems, MULTI solutions support broader quality and compliance initiatives. They can receive task-specific parameters and return tightening data for full traceability and documentation.

Used in conjunction with our DeMeter data-driven solutions, the MULTI allows you to collect, optimize, analyze, and present your assembly production data so you can track, trace, and improve your processes.

Support is available from the Desoutter Service team, who can help with installation, commissioning, tool maintenance, and software support. They also offer data analytics services to help boost your production.
