OVERVIEW

A design dimension has a practically permissible range of error, and the difference between its maximum and minimum is the tolerance. Agreeing which tolerance applies in advance is what keeps measurement results from becoming a dispute.

Measurement is affected by its environment. Temperature changes deform material and airborne dust causes friction in instruments. We keep the measuring location and conditions constant so the same value comes out whoever takes the measurement.

WHAT WE MEASURE

Main items measured

These are the items we check with the measuring equipment we hold. The scope of the check varies with the item.

Send a drawing and have it checked

Micrometer · vernier calipers

Height

Height and steps from a datum face

Height gauge

Complex geometry

Non-contact measurement of dimensions and angles on small parts and complex geometries

Coordinate measuring machine · 2D vision measuring machine

Roundness

Roundness and form of circular parts

Roundness and form measuring machine

Surface roughness

Roughness of the machined surface

Surface roughness tester

Fine features · surface

Examination of the surface and fine features under magnification

Precision optical microscope

※ The items checked and the acceptance criteria vary with the part and the requested conditions. Send us a drawing or a sample and we will review it and reply.

INSPECTION PROCESS

The inspection process

Finished products pass through the measuring room before shipment. Anything that does not match the figures you requested is not shipped.

01

Measurement after machining

We measure the finished part against the dimensions on the drawing.

02

Visual inspection

The surface is inspected for dents, cracks and breakage.

03

Re-check after cleaning

After cleaning we check it once more.

04

Shipment via the measuring room

Parts that have passed the measuring room ship in dedicated packaging matched to the product.

DRAWING & TOLERANCE

Tolerances and drawings

To the customer's drawing

We machine to the customer's design drawing and measure the dimensions it specifies.

Tolerance control

Judged against the permissible range agreed with you.

Shipment decision

Anything that does not match the figures you requested is not shipped.

Send us a drawing and we will reply on whether we can measure it

Noting the dimensions and tolerances you need checked speeds up the review. If you have a sample, we can work from that as well.
