JINTAT / CNC TURNING01CNC TURNING
CNC Turning
CNC turning for shafts, sleeves, flanges and threaded components. We plan the outside diameters, bores and mating surfaces around the rotational datum and required fits, including prototype and low-volume work.
- Maximum diameter
- Ø250 mmSubject to part and workholding review
- Maximum length
- 500 mmPart proportions and support reviewed separately
- Combined operations
- C-axisSecondary hole machining
JINTAT / CNC MILLING02CNC MILLING
CNC Milling
CNC milling for multi-face parts, hole patterns, profiles and fixtures. Datum selection and tool access guide the setup plan for prototype and low-volume milled parts.
- Maximum work envelope
- 1500 × 800 mmSubject to geometry and fixturing review
- Holes & profiles
- Multi-faceMultiple operations and fixture machining
- Low-volume production
- High-mixDifferent parts in small batches
JINTAT / MILL-TURN03MILL-TURN
Mill-Turn
Mill-turn combines rotational surfaces, cross holes and eccentric features in one process plan. Fewer setups help maintain the geometric relationships that matter to assembly. Tool access and machining space are reviewed first.
- Turning & milling
- CombinedOperations planned around part features
- Shared datums
- Fewer setupsReduced re-positioning error
- Holes & offsets
- Cross featuresTool access checked before machining
Which machining process fits your part?
A process name is a starting point for a drawing review. The geometry, required relationships between features, material, quantity and inspection requirements determine the machining plan. Jintat offers CNC turning, milling and mill-turn machining; the comparison below helps you identify the questions to discuss before quotation.
| Process | Example parts and features | What needs review |
|---|---|---|
| CNC turning | Shafts, sleeves, flanges, bores and threaded components built around a rotational axis | Support and workholding, diameters and fits, thread requirements, and the relationship between the datum and critical surfaces |
| CNC milling | Faces, slots, profiles and hole patterns on one or more sides, including those on fixture components machined to drawing | Datum selection, tool access, clamping surfaces and the relationship between features made in different operations |
| Mill-turn machining | Parts combining turned surfaces with cross holes, flats on the outside diameter, or other features requiring drilling or milling | Tool access, workholding suitability, and how critical geometric relationships will be maintained |
A round part can still need a milling operation
Consider a hypothetical sleeve with a precision bore, a radial hole through its wall and a flat on its outside diameter. The bore can be evaluated for internal turning; the radial hole and external flat require a separate review of drilling and milling operations. To evaluate a mill-turn route, identify which relationship matters to assembly: the hole relative to the bore, the flat relative to a datum, or another drawing-defined requirement.
The supplier then reviews tool access, clamping and the measurement method. A combined route may be worth evaluating, but fewer setups do not by themselves guarantee that every feature can be completed in one setup or that a tolerance will be met. This example illustrates a review decision; it is not a customer case or a capability guarantee.
Send the requirements that drive the decision
Provide the current drawing and revision, material and condition, immediate quantity, required finishing and the features that affect fit or function. Include the inspection records needed for acceptance and flag unresolved requirements for review.
You do not need to select the machine in advance. Describe what the finished part must achieve so the machining and inspection plans can be reviewed together.
Explore turning, milling and mill-turn details, then see quality and measurement support.

PROJECT REVIEW
Planning prototype and low-volume CNC parts
Jintat supports prototypes, engineering revisions and high-mix low-volume work. The drawing, material, quantity and critical features guide process planning. Share the current revision and flag any requirements still open for review.
What will be checked before machining?
We review drawing revisions, datums, tolerances and fixturing before planning the machining sequence. First-piece checks, production checks and final measurement follow the inspection requirements for the part.
Read about industries that benefit from low-volume machining →What inspection records can be requested?
Critical-dimension records are available by project requirement. They can include specification limits, measurement equipment, inspection frequency and measured values. Identify the features and records needed when sending your drawing.
The anonymized sample shows an actual report format, not a tolerance guarantee for other parts.
Review inspection methods and the sample report →What should you send for a quotation?
- Drawing and revision: PDF / STEP / DWG / DXF. Include both PDF and STEP when available.
- Quantity and material: State the prototype or expected volume and the specified material, or mark it for review.
- Critical requirements: Identify tolerances, inspection records and any heat treatment or surface finishing.
- Target delivery: Include your requested date for review.
Incomplete information is fine; we will identify what needs clarification. The form accepts one upload at a time; combine multiple files in a ZIP.
