Automatic Longitudinal
Polisher System

TensilePolish is an automatic longitudinal polishing system that improves surface consistency and lowers grinding and residual stress left after turning, milling, and grinding. It prepares clean, uniform surfaces on both cylindrical and flat specimens with minimal operator effort.

Better surface quality is what makes demanding fatigue and tensile results repeatable. Explore the TensilePolish longitudinal polisher.

Machining leaves tool marks and residual stress on the specimen surface, and fatigue cracks almost always start at the surface. Rough or circumferential marks act as stress concentrators that can trigger early failure and add scatter to your results.

A clean, directional finish removes those crack starters. Learn more about our standards and certification.

Polishing is carried out automatically and along the specimen’s length, and the process is controlled so contact between the specimen and any one area of the paper happens only once. That keeps fresh abrasive on the surface for consistent, repeatable results.

Automating the pass removes operator-to-operator variation. To see it on a model, talk to a specialist.

It polishes both cylindrical and flat specimens across a range of diameters and lengths, so one system covers round and flat work. The parameters adjust to the specimen size.

This flexibility suits labs preparing several specimen types. To confirm your specimens fit, request a personal quote.

It prepares surfaces in line with the common fatigue and surface standards, including:

• ASTM E466
• ASTM E606
• EN 6072
• NADCAP

ASTM E466 covers force-controlled constant-amplitude axial fatigue testing of metals, where surface quality strongly affects the result. See our standards and certification.

The process is fully adjustable from an intuitive touchscreen, including:

• Rotation speed
• Applied force
• Polishing speed
• Active polishing length

Storing settings keeps each specimen type consistent. To match settings to your work, talk to a specialist.

Yes. It is designed to lower the grinding and surface residual stress left after turning, milling, and grinding. Reducing that near-surface stress improves fatigue life and the reliability of high-precision results.

Lower residual stress means fewer surprises in fatigue testing. Learn more about our standards and certification.

Yes. The process is controlled so contact between the specimen and any one area of the paper occurs only once, so the surface always meets fresh abrasive. This is a key reason the finish is consistent from specimen to specimen.

Fresh abrasive each pass is what makes the result repeatable. To see the system, talk to a specialist.

It is used after turning, milling, and grinding, as a finishing step before testing. It cleans up the surface those operations leave and prepares the specimen for fatigue or high-precision tensile work.

It complements, rather than replaces, your preparation machines. Explore in-house round specimen preparation.

It is most valuable for fatigue testing and for aerospace or NADCAP-governed work, where surface finish is tightly controlled. Any lab chasing low scatter in high-precision tensile or fatigue results benefits from a consistent surface.

If your specs call out surface finish, this step matters. To discuss requirements, request a personal quote.

Yes. It handles a range of diameters and lengths, so small coupons and larger specimens can both be finished on the same system. The adjustable active polishing length sets the treated zone.

One system covering a size range simplifies your lab. To confirm sizing, request a personal quote.
