Combined Machining
When Turning and Milling Should Be Combined
If a part includes not only rotational surfaces but also slots, flats, cross holes, faces or off-axis features, turning alone is not enough. Combining operations reduces the number of setups and helps maintain more accurate relationships between features.
01Fewer part setups
02Accurate relationship between slots, holes and faces
03Fewer errors between operations
04Consistent repeatability across a batch
Some parts are machined on HAAS ST-15Y or HAAS ST-10Y machines with Y-axis and live tooling. For more complex geometry, we combine turning with multi-axis milling.

Equipment
Turn-Mill Machining Equipment
Our equipment allows us to combine turning and milling based on part geometry, size and accuracy requirements. Y-axis turning centers with live tooling support turning, drilling, threading and milling without transferring the part to a separate milling machine.

In-Process Quality Control
Inspection After Critical Turning and Milling Stages
Before machining, we review technical requirements and the workholding strategy. During production, we verify parameters that affect subsequent operations, then inspect finished parts before release.
01
Documentation Review
We review geometry, material, datums, tolerances, fits, surface finish and positional relationships between turned and milled surfaces.
02
First Article Inspection
For production runs, we inspect critical parameters on the first part before continuing the batch when required by the process.
03
In-Process Inspection
We verify dimensions and datum surfaces after operations where deviation could affect subsequent turning or milling.
04
Final Inspection
We verify the agreed parameters of finished parts before packing, handover or delivery.

Quote & Pricing
Turn-Mill Machining Cost Depends on the Process Route
Pricing considers more than part size and material. We account for the number of turning and milling operations, whether they can be completed in one setup, required tooling and fixtures, and batch size.
After Engineering Review
Our engineer reviews the drawing or 3D model and defines the operation sequence, workholding, equipment and inspection plan. We then confirm price and lead time.
01Workpiece MaterialGrade, material type, stock form and dimensions.
02Heat & Thermochemical Treatment / PlatingHeat and thermochemical treatment (hardening, carbonitriding, carburizing, etc.) and surface coatings (chemical oxidation, anodizing, zinc plating, chrome plating).
03Diameter, Length & GeometrySurface types, number of operations and profile complexity.
04Milled FeaturesFaces, flats, slots, pockets, holes, angled features and off-axis elements.
05Tolerances & Surface FinishFits, dimensional accuracy and positional relationships of critical surfaces.
06Number of SetupsWhether the part can be completed in one setup or requires additional operations and repositioning.
07Batch SizeOne-off part, small batch or recurring production.
08Fixtures & ToolingSpecial clamping, fixtures, live or non-standard tooling and any dedicated process tooling that must be manufactured.
09Secondary OperationsBalancing, rubber coating and other related processes when required.

Frequently Asked Questions
What to Know Before Ordering CNC Turn-Mill Machining
What information do you need for an accurate quote?
Ideally, send a drawing and/or 3D model, material, quantity and technical requirements. Clearly identify critical dimensions, fits, threads, surface finish requirements and positional relationships where they are functionally important.
When is turn-mill machining the right choice?
It is the right choice when a part is primarily rotational but also requires faces, flats, slots, cross or offset holes, pockets or other milled features. If these features are not required, conventional turning may be sufficient.
Can turning and milling be completed in one setup?
For many parts, yes. HAAS ST-15Y and HAAS ST-10Y machines have a Y-axis and live tooling, allowing turning, milling, drilling and threading to be combined in one setup. More complex or larger parts may require a multi-machine process route.
Do you take one-off parts and small batches?
Yes. We handle both one-off parts and production batches. For a one-off part, programming, setup, workholding and tooling make up a larger share of the cost. In a batch, these preparation costs are spread across more parts, which can reduce the unit price.
Which operations can be combined in one order?
Depending on the geometry, this may include OD and ID turning, facing, boring, drilling, threading, grooves and milling of faces, flats, slots, pockets and local contours. The final process route is defined by our engineer.
What are the maximum part dimensions?
On our turning equipment, we can machine parts up to 1500 mm in diameter and up to 5000 mm in length. For combined turn-mill machining, the allowable envelope depends on part geometry, the milling zone, workholding and selected equipment, so feasibility is confirmed after reviewing the drawing.
What materials do you machine?
We machine structural, stainless and alloy steels, aluminum alloys, brass, bronze, copper, engineering polymers and other materials subject to engineering review. Include the material grade and stock condition in your request whenever possible.
Can you manufacture a part from a sample or sketch?
We review this case individually. If no original documentation is available, our engineer will determine whether the sample or sketch provides enough information to reconstruct the geometry and prepare the data required for production.
What determines lead time?
Lead time depends on geometry complexity, number of turning and milling operations, material availability, tooling and fixtures, batch size, machine load and secondary operations. We confirm the lead time after engineering review.
