CNC Splined Shafts

 

What Are CNC Turned Shafts?

CNC turned shafts are cylindrical mechanical components produced by rotating raw material against stationary cutting tools. This subtractive process removes material to create precise outside diameters, functional shoulders, retaining grooves, chamfers, and threads.

 

Dimensional Precision: Tight outer diameter limits ensure proper seating for bearings, couplings, and power transmission elements.

 

Rotational Alignment: High concentricity between stepped sections prevents vibration and premature wear in dynamic assemblies.

 

Functional Integration: Multiple mechanical features are machined into a single shaft to simplify downstream component assembly.

 

Custom CNC Turned Shaft Configurations

Different mechanical platforms require distinct geometric features to handle rotational torque, axial loads, and mechanical alignment.

Straight & Stepped Shafts

Uniform or multi-diameter designs engineered to mount bearings, gears, pulleys, and retaining rings at designated axial positions.

Threaded & Shoulder Shafts

Integrated external or internal threads combined with precision-machined shoulders to provide positive axial positioning and structural fastening.

Grooved & Keyed Shafts

Circumferential grooves engineered for snap rings or seals, alongside milled flat sections or keyways for direct power transfer.

Drive Shafts & Precision Axles

Balanced rotational components tailored for power transmission, pivoting mechanisms, and high-load structural hinge joints.

 

Engineering Materials for Shaft Manufacturing

 

Aluminum Alloys: Lightweight choices such as 6061-T6 and 7075-T6 offer excellent strength-to-weight ratios, corrosion resistance, and high machinability for automation parts.

 

Stainless Steels: Grades including 303, 304, 316L, and 17-4 PH provide high tensile strength, extreme wear resistance, and long-term corrosion protection.

 

Carbon & Alloy Steels: Grades like 1045, 4140, and 12L14 deliver high mechanical strength, surface hardness after heat treatment, and structural durability.

 

Copper Alloys: Brass and bronze materials feature low friction coefficients, natural corrosion resistance, high electrical conductivity, and non-galling properties.

 

Engineering Plastics: Materials such as POM, PEEK, and Nylon offer electrical insulation, chemical resistance, self-lubricating characteristics, and low weight.

 

 

Secondary Machining & Surface Finishing Options

Complete manufacturing capability extends from initial turning to localized secondary machining and surface protection.

 

Secondary Operations
• Precision thread chasing and tapping
• Off-axis cross-hole drilling and reaming
• Flat milling, keyway cutting, and chamfering
• Mechanical deburring and edge rounding

 

Surface Treatment Capabilities
• Anodizing: Type II clear or color anodizing and Type III hardcoat for aluminum surface hardness.
• Plating Options: Electroless nickel, bright zinc, chrome, and passivation for enhanced corrosion protection.
• Oxidation & Nitriding: Black oxide and QPQ salt bath nitriding for improved surface lubricity and wear resistance.
