Multispindle Turning

Multispindle turning on a Swiss lathe or multispindle lathe enables simultaneous machining of multiple high precision complex parts and small parts, achieving tight tolerances essential for Swiss machining and swiss screw machining applications.

This process uses a bar feed mechanism to advance bar stock through a guide bushing, allowing multiple spindles to cut features along the Z-axis. It excels at producing parts with a high length-to-diameter ratio, such as shafts, pins, and spindles. The result is superior surface finish and precision turned parts ideal for demanding industries.

PMMI brings expertise in handling exotic materials like titanium and stainless steel for safety-critical features. Examples include valve spools in hydraulic equipment and actuator rods for aerospace airframe components. Segmented machining ensures straightness, concentricity, and tight tolerances even in irregular geometries.

Common applications span the medical industry with surgical instruments, the aerospace industry for engine components, and the automotive industry producing transmission gears. Multispindle turning supports cross-hole drilling and complex profiles on fittings, nuts, and bushings. This method boosts efficiency for high-volume production of precision turned parts.

Unique Bar-Feed Mechanism

The unique bar-feed mechanism in Swiss screw machines, featuring a guide bushing and collet system with bar stock, supports continuous production of high precision parts and cylindrical parts vital for swiss machining.

This setup excels at maintaining straightness, concentricity, and tight tolerances for parts with high length-to-diameter ratios. The guide bushing keeps the bar stock stable close to the cutting tool. This minimizes deflection during long cuts on slender shafts or pins.

PMMI uses this technology for irregular geometries, cross-hole drilling, and components like fittings, nuts, and washers. It enables precise operations on complex parts in the automotive and aerospace industries. For example, engine components and airframe spindles benefit from this steady feed.

In practice, the mechanism supports swiss screw machining of safety-critical features from materials like titanium or stainless steel. It ensures superior surface finish on valve stems and actuator rods. Industries rely on it for reliable production of small parts with demanding specs.
