Single-Spindle Machining: Certified High Precision

Our expertise in single-spindle machining enables us to produce complex, technical and miniaturized parts with uncompromising precision. Our latest-generation single-spindle machines ensure flexible and competitive production for small, medium and large series alike.

 

Single-Spindle Machining: Flexibility and Performance

Single-spindle screw machining is an ideal solution for:

Production of individual parts and small high value-added series

Machining complex geometries with high repeatability

Manufacturing prototypes or industrial pre-series

 

Principle of Single-Spindle Technology

A single spindle (chuck) operates at a time. Each part is machined sequentially.

Characteristics

• Simpler and less costly machine

• Ideal for small and medium series, prototypes or complex parts requiring multiple operations

• Longer cycle times, as each part is produced individually

Advantages

• High flexibility when changing production

• Well suited for precision parts and small to medium quantities

Limitations

• Limited productivity

• Less cost-effective for large series

 

High-Precision Multi-Spindle Machining – Flexible Series for Industry

Thanks to a fleet of latest-generation multi-spindle machines, we ensure flexible and competitive production for small, medium and large series. We support global OEMs across numerous industries.

 

Multi-Spindle Technology Serving Performance

Multi-spindle screw machining allows several machining operations to be performed simultaneously on the same part, providing:

Increased productivity through reduced cycle times

Dimensional precision meeting the tightest tolerances

Perfect repeatability, even at high volumes

Cost optimization while ensuring consistent quality

 

Principle of Multi-Spindle Technology

Several spindles (typically 6 or 8) operate in parallel. Each spindle performs a different operation on a part, and the parts move from one station to the next.

Characteristics

• More complex and costly machine

• Designed for large series and high-speed production

• Very short cycle times, as multiple parts are machined simultaneously

Advantages

• Very high productivity

• Highly cost-effective for large volumes

Limitations

• Less flexible (long setup times when changing references)

• High initial investment

 

Rotary Transfer Machine Technology (6, 8, 12 and 20 Stations)

 

Operating Principle of a Rotary Transfer Machine

A rotary transfer machine is designed to produce complex parts in large series. The part is fixed on a rotating table that moves from one station to another. Each station performs a specific operation (drilling, milling, tapping, turning, etc.). At the end of the cycle, the part is fully machined.

Characteristics

• Number of stations: typically 6 to 24, depending on complexity

• Production: very fast, with several operations performed in parallel

• Flexibility: lower than single-spindle, but more adaptable than multi-spindle for complex parts

• Investment: very high, but offset by productivity

Advantages

• Short cycle time: all operations integrated into a single machine

• High precision, as the part remains fixed on the same fixture

• Ideal for complex parts in large series

Limitations

• Long setup times when changing references

• Higher cost

• Less suitable for small series

 

Escomatic-Type Machines

Principle of the Technology

Escomatic machines are screw machines without a rotating chuck:

• The bar does not rotate; the cutting tool performs the cutting motion

• The bar is continuously fed through the machining zone

• This technology is specialized for the production of small cylindrical parts in very large series

ESCOMATIC = ultra-high productivity for small cylindrical parts in large series, using a unique system where the bar remains stationary and the tool rotates.

Characteristics

• Extremely high output: up to several thousand parts per hour

• Bar diameter: typically from 0.3 mm to 6 mm

• Possible operations: turning, threading, grooving, drilling, etc.

• Compact: small footprint, ideal for mass production

Advantages

• Extreme productivity for small parts

• Very low unit cost for large series

• Reduced vibration (fixed bar), ensuring good precision

• Rapid bar change thanks to continuous feeding

Limitations

• Limited to small parts (small diameters)

• Less suitable for complex parts

• Specific investment (dedicated machines)

Application Examples

• Electronics / Connectivity: contacts, pins

• Watchmaking: shafts, miniature screws

• Automotive: small precision parts (pins, shafts)

• Medical instrumentation: micro-components
