CNC Turning Design Guidelines
Diameter stepRadiusSlender ratio
Active design chapter
Axis, diameter and transition control
Round Corner Transition
Corner radius ≥ R0.5
Design rounded transitions instead of sharp corners. Recommended corner radius ≥ R0.5 for safe tool retraction.
Slender Shaft Ratio Control
Length-to-diameter ratio ≤ 8:1
Control the length-to-diameter ratio of slender shafts within 8:1. Excess ratio will cause bending and runout.

What is CNC turning used for?
CNC turning is mainly applied to manufacture rotational symmetrical parts such as shafts, fasteners and tubular components widely used in industrial machinery.
What is the difference between milling and turning?
Turning is suitable for rotary parts, while milling is for irregular complex structures. We provide both processing technologies for one-stop customization.
Can you process tiny precision shafts?
Yes. Our Swiss-type lathe supports ultra-slender miniature shafts with high coaxiality and smooth surface.
What materials are suitable for turning?
Aluminum, stainless steel, carbon steel, brass, magnesium alloy and multiple engineering plastics.
Do turned parts need surface treatment?
Surface finishing such as phosphating and electroplating can improve hardness, corrosion resistance and appearance.
What is your tightest turning tolerance?
The strictest tolerance can reach ±0.005mm for high-precision industrial turning components.
Do you provide threaded custom parts?
Yes, we support various standard and non-standard thread turning, including fine thread and deep hole thread processing.
Can you support large batch production?
Absolutely. We have stable monthly production capacity to meet large-volume batch orders with consistent quality.
How about your delivery cycle?
Prototype orders take 1-3 working days, and mass production takes 7-15 working days depending on quantity.
