Upload CAD FilesTight Tolerance Control for Precision Turned Parts
ApexBatch supports precision CNC turning for parts that require controlled diameters, roundness, concentricity, runout, thread accuracy, and surface finish. Final achievable tolerances depend on material, geometry, wall thickness, part size, and drawing requirements.
What We Control
Diameter & Fit
For shafts, bushings, sleeves, pins, and mating components that require stable assembly dimensions.
Roundness & Runout
For rotating, positioning, and cylindrical parts where alignment and smooth movement matter.
Thread & Surface Quality
For threaded inserts, fittings, connectors, and sealing features that require thread accuracy and controlled surface finish.
Drawing-Based Review
Final tolerances depend on material, geometry, wall thickness, part size, and drawing requirements.

Frequently Asked Questions
Your Questions, Our Expertise.
Find answers to common questions about CNC turning quotes, DFM review, materials, tolerances, surface finishes, inspection, and delivery.
CNC turning is suitable for round, cylindrical, threaded, and rotational parts, such as shafts, pins, bushings, sleeves, spacers, standoffs, threaded inserts, connectors, fittings, nozzles, rollers, and precision cylindrical housings.
ApexBatch supports commonly used metals and engineering plastics for CNC turning, including aluminum, stainless steel, steel, brass, copper, bronze, titanium, POM, PEEK, PTFE, PA, PC, PMMA, and ABS. Material selection can be reviewed based on strength, weight, wear resistance, corrosion resistance, insulation, or appearance needs.
CNC turning rotates the workpiece while cutting tools shape round or cylindrical features. CNC milling uses rotating cutting tools to remove material from a fixed workpiece, making it more suitable for flat surfaces, pockets, slots, and complex 3D shapes.
ApexBatch supports turning, boring, drilling, tapping, threading, grooving, knurling, parting, facing, internal and external turning, and secondary milling for features such as flats, slots, side holes, cross holes, and other non-round details.
CNC turning cost depends on material, part size, geometry, machining time, tolerance requirements, surface finish, inspection needs, and production quantity. The most accurate way to estimate cost is to upload your CAD files and drawings for review.
Yes. ApexBatch supports CNC turning for both metal and plastic parts. Common plastic options include POM, PTFE, PEEK, PA, PC, PMMA, ABS, PE, PP, FR-4, and Bakelite, depending on your application, tolerance, and surface requirements.
Our standard CNC turning tolerance is ±0.05 mm, with precision tolerance down to ±0.01 mm for selected features. Roundness, concentricity, and runout requirements can also be reviewed based on material, geometry, wall thickness, part size, and drawing requirements.
Choose CNC turning if your part is mainly round, cylindrical, threaded, or shaft-like. Choose CNC milling if your part has complex flat surfaces, pockets, slots, or multi-face features. Some parts may require both CNC turning and secondary milling.
CNC turning lead time depends on material availability, part complexity, tolerance requirements, surface finish, inspection needs, and order quantity. After reviewing your drawings and requirements, ApexBatch can provide a clearer production lead time with your quote.
To get a faster and more accurate quote, please provide CAD files, 2D drawings, material requirements, quantity, tolerances, thread specifications, surface finish needs, inspection requirements, and any special packaging or delivery needs.
