XILILAI / CAPABILITIES
CNC turning.
Review CNC turning for shafts, sleeves and threaded interfaces. Specify material condition, diameters, fits and finish for a component quotation.
In-house manufacturingCNC turning for connected diameters and interfaces.
Shafts, sleeves, coupling bodies and threaded adapters depend on relationships between bores, outside diameters and shoulders. Identify the assembly datums and mating requirements so the turning and inspection plans answer the same question.
Bores, shoulders and threads
State the thread designation, effective length and acceptance requirement. Mark sealing or locating faces separately from clearance features. Where coaxiality is functionally important, define the relevant datum axis and geometric tolerance. Matching nominal diameters alone do not define the fit.
Secondary features and route selection
Cross-holes, flats and milled profiles may require additional operations. Review their location relative to the turned features. For slender components, compare Swiss-type turning with the proposed conventional turning setup rather than choosing by part length alone.
Surface condition and verification
Identify burr-sensitive intersections, edge conditions and any treatment after machining. For fluid interfaces, component dimensions and material records do not by themselves establish pressure or leak performance; agree any functional test separately.
What to include in your project
- Drawing revision, material grade and material condition
- Critical diameters, bore depths, shoulder locations and mating-part requirements
- Thread standard, pitch, engagement length and inspection requirements
- Grooves, cross-holes, edge requirements, finish and batch quantity
A nominal diameter alone does not define a mating fit. Include the required limits or fit designation, surface requirements and relevant geometric controls on the drawing. Slender parts can also be reviewed for Swiss-type turning.
