When to review hard turning
Hard turning services may be considered for rotational parts where the material condition and required geometry suit the process. Suitability depends on the specific material, hardness condition, part shape, tolerance and finish. This page does not state a universal hardness range or guaranteed tolerance.
Information to include on the drawing
Identify material grade and condition, critical diameters, shoulders, grooves, datums and surface finish. Mark which dimensions control fit or function and how they should be inspected. If heat treatment or another process occurs before turning, state the required sequence and when the final dimensions apply.
Coordinate finishing and inspection
Some parts may require a combination of hard turning, grinding or other finishing. Show which operation creates each critical feature and identify the acceptance method. If the drawing calls for a particular surface condition or report, include it in the RFQ rather than assuming it is included.
Quote review checklist
- Material grade and condition are specified
- Critical diameters, datums and finish are identified
- Heat treatment and machining sequence are clear
- Inspection dimensions and report expectations are listed
- Secondary operations, packaging and shipping are included or excluded explicitly
For general rotational parts, review the CNC turning service. Ask for a drawing review if the part may require a different process route.
Confirm the scope before ordering
Resolve material condition, operation sequence and acceptance requirements before comparing quotes. Process choice and final results must be reviewed against the actual part, not inferred from a service label.
Submit the drawing, material, quantity and inspection scope through the custom machining quote page.
