Escomatic Machining

Small-Diameter Production, Redefined

Escomatic machining is an ultra-efficient turning process where the cutting tools rotate around a stationary wire or bar fed directly from coil. This configuration enables continuous production, extremely short cycle times, and virtually zero bar waste — a game changer for high-volume manufacturing of small, precision parts.

Key Capabilities:

• Maximum finished diameter: Ø4mm

• Material input: Continuous coil feed (no bar feeding or remnant loss)

• Ultra-fast cycle times — ideal for large batch runs

• Minimal setup time and quick changeovers

• Excellent repeatability across long production runs

Best Suited For:

• Miniature shafts and dowel pins

• Bushings and collars

• Electrical terminals and contacts

• Watch and instrumentation parts

• Automotive micro-components

• Any small, cylindrical part with tight tolerances and high volumes

Why Escomatic?

• Lower cost per part: Less waste, less cycle time, less handling

• Built for volume: Production runs in the hundreds of thousands

• Stable and repeatable: Even across weeks-long jobs

• High reliability: Minimal tool deflection due to tool-rotation design

If your part is small, cylindrical, and needs to be produced at scale — this is the most efficient way to do it.

Centerless Grinding

Precision Finishing for Perfect Cylindrical Consistency

For components requiring highly accurate outside diameters, tight tolerances, and fine surface finishes, centerless grinding is the finishing process of choice. Unlike conventional OD grinding, centerless grinding doesn’t require part centering — enabling faster cycle times and smoother part transitions in high-volume setups.

Key Capabilities:

• OD tolerances as tight as ±0.001mm

• Surface finishes down to Ra 0.2 µm

• In-feed and through-feed grinding options

• Consistent roundness and cylindricity on long or slender parts

• Continuous material feed for high-output environments

Best Suited For:

• Precision dowel pins

• Guide rods and plungers

• Journal and bearing surfaces

• Valve components

• Shafts and spacers post-machining

Why Centerless Grinding?

• Superior OD precision on parts turned from Swiss or Escomatic processes

• High production throughput without losing dimensional control

• Ideal for small parts that require ultra-smooth finishes or exacting fits

• Low-friction support avoids part distortion or vibration

It’s the final step for parts that need to look perfect, fit perfectly, and perform flawlessly.

A Streamlined Workflow from Start to Finish

By integrating Escomatic and centerless grinding in-house, Turntech provides a complete solution for small-diameter, high-volume parts — from rough form to high-precision finish. These processes work hand-in-hand, especially for components requiring consistent OD dimensions across large batch sizes.

We’ve engineered our workflow to eliminate unnecessary handling, reduce lead times, and ensure your components meet spec — every time.
