Why shops switch

You are not paying for the ruby. You are paying for a part number and a two-week quote cycle.

Most stylus cost sits in distribution and paperwork, not in the sapphire sphere or the grinding. We sell the geometry and the proof, and we answer the same day.

01

Proof, not promises

Every batch ships with a calibration report traceable to an ISO/IEC 17025 accredited laboratory — ball diameter, sphericity, straightness and thread fit measured, not declared.

02

Quotes in 24 hours

Send a drawing, a part number or a photo. You get price, lead time and freight the next business day — not a "we will revert" that never arrives.

03

Custom in 72 hours

Non-standard lengths, stepped stems, star configurations, carbide or ceramic. Drawing to first article in three working days, so a broken probe stops costing you a week.

Quality & calibration

The certificate your auditor actually asks for

We are a manufacturer, not a calibration laboratory — so we do not claim an accreditation we do not hold. What we do is send every batch to an accredited laboratory and ship the report with the goods.

  • Ball diameter deviation and sphericity measured per batch
  • Surface roughness and stem straightness on request
  • Thread go / no-go gauge on every threaded stylus
  • Report carries the laboratory's accreditation mark and is traceable to national standards
  • Per-piece certificate available for incoming-inspection requirements
How the calibration works

Custom geometry

When the OEM catalogue has no answer

Stepped stems for a deep bore. A 3 mm ball on a 120 mm carbide shaft. A star build that clears a fixture. Send the drawing at 9am, hold the first article on Thursday.

STEP 01

Send the spec

Drawing, sketch or a photo with dimensions. Thread, ball size, stem material and overall length is enough to quote.

STEP 02

Feasibility in 24h

We confirm geometry, tolerance and price the next business day — including what we cannot hold.

STEP 03

First article in 72h

Machined, assembled and measured. Photos and measured values before it ships.

STEP 04

Production

15 working days for volume. Same fixtures, same operator, same report.

Tell us which stylus you burn through fastest.

We will send one free of charge — you cover the freight, and we credit it back on your first order. Measure it against what you run today. If it is out of tolerance, we do not want the order.
