START WITH THE COMPONENT

What are you making?

Explore a starting route for your geometry. Your drawing, material and quantity determine the final manufacturing plan.

A STARTING POINT FOR YOUR DRAWING

Start with turning.

Shafts, sleeves, bushings and connectors often start from a rotational machining route. Long, slender or small-diameter features may benefit from Swiss-type machining.

QUALITY STARTS WITH THE REQUIREMENT

Define the feature.
Agree the evidence.

Make inspection part of the manufacturing plan. Identify the dimensions, material condition, surface and documentation that matter before the order is released.

  • Drawing and revision review
  • In-process and final checks
  • Agreed inspection before final payment
  • Project-specific reporting and documentation
Discuss your inspection requirements

Connect the component, measurement method and acceptance requirements.

Environmental durability requirements

Specify salt-spray, UV aging or temperature-and-humidity testing where your application requires it. Agree the method, duration, acceptance criteria and report scope before production.

Inspection methods & equipment

Open a method to see what it checks and why it matters.

Profile Measuring Instrument+

Captures a two-dimensional contour trace for arcs, radii, chamfers, steps, sealing profiles and other features that are difficult to verify with hand tools.

What it checks
Profile geometry and drawing-defined contour tolerances.
Why it matters
Provides recorded contour data for complex functional surfaces before shipment.
Roundness Tester+

Evaluates circular and rotational geometry on shafts, bores, sleeves and other turned components.

What it checks
Roundness, cylindricity, concentricity and radial runout where specified.
Why it matters
Supports stable fits, rotation and assembly alignment for precision components.
CCD Optical Sorting Machine+

Uses configured camera criteria to screen repeat-production parts for visible and measurable features at production speed.

What it checks
Burrs, cracks, missing features, mixed parts, edge damage and selected dimensions.
Why it matters
Improves consistency when a batch requires repeatable automated screening.
Vickers Hardness Tester+

Uses a controlled diamond indentation to evaluate material hardness on small parts, thin sections and treated surfaces.

What it checks
Vickers hardness and the condition of heat-treated or surface-treated material.
Why it matters
Adds objective hardness evidence where mechanical performance depends on material condition.
Surface Roughness Tester+

Traces the machined surface to quantify finish rather than relying on appearance or touch.

What it checks
Drawing-defined surface parameters such as Ra and Rz.
Why it matters
Supports sealing, bearing, wear and cosmetic requirements on functional surfaces.
Air Gauge+

Uses pneumatic comparison measurement for rapid, non-contact checking of closely controlled bores and diameters.

What it checks
Internal diameter, external diameter and selected width or clearance features with the appropriate tooling.
Why it matters
Supports fast repeat checks without marking sensitive finished surfaces.
Coordinate Measuring Machine (CMM)+

Collects three-dimensional coordinate data from complex machined parts for dimensional and geometric inspection.

What it checks
Position, flatness, perpendicularity, alignment and other drawing-defined dimensions or GD&T controls.
Why it matters
Provides traceable first-article and final-inspection evidence for complex geometry.
Optical Emission Spectrometer (OES)+

Analyzes elemental composition to support identification of incoming metal grades before machining.

What it checks
Material chemistry and grade consistency for applicable metallic materials.
Why it matters
Reduces material mix-up risk and strengthens incoming-material traceability.
RoHS Compliance Screening+

Screens applicable materials for regulated substances as part of the compliance-control process.

What it checks
Restricted-substance screening against the agreed material and market requirements.
Why it matters
Supports compliance documentation and identifies when additional laboratory verification is required.

USEFUL ANSWERS

Before you
send the part.

Can you manufacture one part or a small batch?+

Yes. WEKO offers single-piece and low-MOQ options for suitable CNC-machined components, alongside repeat production. Tooling-based processes such as stamping and die casting need a separate quantity and tooling review.

How do I choose between turning, milling and Swiss machining?+

Start with the drawing. Rotational geometry often suggests turning; faces, pockets and mounting patterns suggest milling. Slender or small turned components may suit Swiss-type machining. Some components combine processes. We review the route against your material, dimensions and quantity.

Does ±0.0001 mm apply to every machined part?+

This capability applies to suitable centerless-ground features. It is not a universal turning or milling tolerance. Define the dimension, material condition, measurement method and acceptance requirements for engineering review.

Which materials and finishes can I request?+

Discuss aluminium, stainless steel, steel, brass, copper and engineering plastics. Give the exact grade and condition. Request the surface treatment, coating, cosmetic standard and any certification or inspection needs in your RFQ.

How fast can you deliver?+

Expedited options start from 3 business days. Your part, material availability, process, quantity, finishing and inspection requirements determine the confirmed quotation schedule.

Can I protect my drawing with an NDA?+

Yes. Request an NDA before uploading sensitive files. Begin with a general description if you need to agree confidentiality before sharing geometry.

What inspection evidence can I request?+

Specify critical features, the inspection method, sampling or first-article requirements and documentation before order approval. WEKO can discuss dimensional, form, surface, material and other project-specific checks using the listed equipment. The quotation confirms the agreed evidence.
