THE PROCESS BEHIND THE PART
Geometry. Material. Critical features.
CUSTOM TURNED COMPONENTS
Built around the surfaces
that make your part work.
From bearing fits to threaded connections, each feature has a job. We review the whole component so your critical dimensions, material and finish guide the process.
Sleeves & bushings
Inside and outside diameters, wall thickness and fits defined by your drawing.
Threaded connectors
External and internal connections with clearly specified thread and sealing requirements.
Round housings & end components
Bores, flanges and mating faces, with secondary machining reviewed where needed.
WEKO / TURNING EXPLORER
Every diameter.
Every interface.
Inspect the stepped geometry, flange and functional interfaces of a representative shaft.

ILLUSTRATIVE PROCESS STUDY / YOUR DRAWING DEFINES THE REQUIREMENTS
Define the surfaces that locate the part.
Mark critical diameters, shoulders and datums. Specify fits, form controls and surface finish where the component meets another part.
Review your fitsA thread needs more than a diameter.
Include thread standard, pitch, class and useful length. Dimension grooves, reliefs and edges, and identify any required thread gauges.
Review threads and groovesControl the inside and the outside together.
Define bore size, depth and finish. Add concentricity or runout requirements where needed, referenced to the functional datums.

CNC TURNING / USEFUL ANSWERS
Before you
quote the part.
Which parts are suitable for CNC turning?+
Turning is a starting route for rotational features such as shafts, sleeves, bushings, bores and threaded components. A part may combine turning with milling, grinding, finishing or other operations. Send the full drawing so the complete route can be reviewed.
Can I order one prototype or a small batch?+
Yes. WEKO offers single-piece and low-MOQ CNC options as well as repeat production. Material, geometry, setup, finishing and inspection determine the quoted price and schedule.
What tolerances can you achieve?+
The existing capability list gives ±0.002 mm for the listed turning equipment. Your material, geometry, setup and measurement requirements determine the tolerance that can be confirmed for a specific feature. Centerless grinding capability down to ±0.0001 mm applies to suitable ground features and is reviewed as a separate process.
Do you offer Swiss-type turning?+
Yes. The listed Star and Tsugami Swiss-type equipment has a published working range up to Ø32 × 400 mm. This is an equipment envelope; confirm your full geometry, material and critical requirements during drawing review.
Can turned parts have milled flats, holes or slots?+
Discuss the complete drawing, including non-rotational features. The manufacturing review establishes the combination of turning, milling and any other operations required.
Which file and project details should I provide?+
Send a dimensioned drawing or model with its revision, exact material grade, quantity, critical dimensions, thread specifications and finish. Add your inspection, timing and documentation requirements. If files are not ready, start with a part description.
Can I request an NDA before uploading files?+
Yes. Use the NDA enquiry option before sharing sensitive geometry. You can begin with a nonconfidential description and agree how to exchange the drawing.
How fast can you supply turned components?+
Expedited options start from 3 business days. Your quote confirms the schedule after the part, material, volume, finishing and inspection requirements have been reviewed.
