Program the one-clamp route
Active operation
Machine primary diameters, shoulders and concentric references while the workpiece remains controlled by the original clamping system.
We provide premium custom CNC turn-mill combination machining services for industrial clients worldwide. Equipped with professional multi-axis CNC turn-mill machines and a full in-house surface finishing workshop, we deliver one-stop custom turn-mill component solutions from rapid prototyping to large-scale mass production. Our stable monthly production capacity and strict quality control ensure consistent high precision and reliable quality for all high-volume custom orders.
Our professional CNC turn-mill combination machining integrates turning, milling, drilling, grooving and tapping processes in a single clamping operation. Different from conventional single-process machining, this composite manufacturing technology eliminates repeated positioning errors, effectively improves machining accuracy and production efficiency, and perfectly solves the processing challenges of complex parts with both rotary structures and irregular milled features.
One datum chain
The value is not simply having more tools. It is completing interconnected geometry before the datum relationship is broken.

We process a full range of high-quality metal materials for precision CNC turn-mill combination parts, including aluminum alloy, stainless steel, carbon steel, alloy steel (4140), brass, copper and magnesium alloy. All raw metal materials are strictly inspected to guarantee high mechanical strength, excellent wear resistance and stable performance for various industrial turn-mill components.
Selected integrated component
Custom CNC turn-mill shafts, including multi-feature transmission shafts, pin shafts and mandrels integrated with holes, grooves and threads, widely used for mechanical assembly and power transmission systems.
We offer comprehensive in-house surface finishing services for all custom CNC turn-mill combination components. All surface treatments are completed in our own workshop to ensure unified batch appearance, improved surface hardness, corrosion resistance and overall durability of finished turn-mill parts.
Selected zone: Turned diameter
Finish and datum protection
As a cost-effective surface treatment for steel CNC turn-mill parts, phosphating forms a uniform gray phosphate conversion film on steel surfaces. It greatly improves wear resistance and paint adhesion without damaging precise dimensional tolerance, suitable for all types of industrial steel composite components.

Active design chapter
Clearance ≥ 1.5× tool diameter
Ensure sufficient clearance between milled features and adjacent shoulders/diameters. Maintain at least 1.5× tool diameter distance from any live-tool feature to the nearest cylindrical surface to prevent holder collision.
Reduce spindle speed 30–50% if unbalanced
Minimize heavy unilateral features (e.g., large flats, deep cutouts) that cause vibration. For unbalanced designs, either add counterweights or reduce spindle speed by 30–50% to preserve surface finish.
Use standard drill, end mill and tap sizes
Specify standard drill, end mill, and tap sizes (metric: 3/6/8/10 mm, imperial: 1/8/1/4 in). Avoid custom non-standard tools to reduce cost and lead time.
