Slotted Stainless Steel Turning Components

These slotted stainless steel components are manufactured through precision CNC turning, focusing on smooth transmission, accurate slotting, and structural stability. They are designed for use in automation equipment, motor-driven systems, precision machinery, and industrial production lines.

With factory-direct supply, we support global small-batch, multi-variety customization. Combining precision slotting technology with standardized surface treatments, our CNC stainless steel turned parts meet the transmission and positioning requirements of a wide range of equipment, offering a cost-effective solution for industrial drive components.

Our factory is equipped with nearly 50 CNC lathes and 30 secondary processing machines, including both fully automatic and semi-automatic equipment, enabling us to handle orders of all volumes for precision metal components.

Customization Service

We provide fast-response customization based on your drawings:

• Shaft diameter and length

• Slot position, quantity, width, and depth

• Step dimensions

• Thread interfaces (imperial, unified, metric, and custom)

• Chamfers and radii

Our engineering team offers rapid drawing evaluation, optimized process planning, and accurate quotations. With flexible lead times and no intermediaries, we deliver one-stop solutions tailored to different transmission applications.

Material & Process Advantages

We use high-quality stainless steel combined with advanced surface treatments such as passivation, zinc plating, zinc-nickel alloy plating, and chrome plating.

Key Benefits

• Excellent mechanical properties with strong machinability, allowing precise multi-position and complex slot designs.

• High-precision slotting with smooth surfaces, no burrs or edge chipping, ensuring tight fit with mating components.

• Stable transmission performance with no jamming or loosening.

• Multiple surface treatment options:

☉ Passivation for base corrosion protection.

☉ Zinc, zinc-nickel, and chrome plating for enhanced wear resistance and corrosion resistance.

• Suitable for indoor, outdoor, and high-humidity environments.

• High structural strength ensures slot areas resist cracking or deformation under load.

• Surface treatments do not affect machining accuracy, maintaining micron-level precision for assembly.

These advantages make our CNC stainless steel turned parts ideal for precision transmission systems.

Precision Manufacturing

Optimized Slotting Technology

CNC slotting parameters and tool paths are optimized using progressive cutting techniques. This minimizes material stress while ensuring excellent surface finish and dimensional accuracy of the slots.

Micron-Level Precision Control

• Shaft diameter tolerance: ±0.02 mm

• Length tolerance: ±0.03 mm

• Slot position tolerance: ≤0.03 mm

• Slot width/depth tolerance: ≤0.02 mm

• Concentricity: ≤0.02 mm

• Perpendicularity: ≤0.03 mm

Ensures both transmission performance and assembly accuracy.

Full Quality Control System

• Raw material composition inspection

• First article inspection for shaft machining

• In-process inspection during slotting

• CMM dimensional and slot accuracy measurement

• Geometric tolerance inspection

• Surface treatment quality verification

• Transmission performance testing

Each process is 100% inspected, ensuring consistent quality and zero defects.

Global Order Support

• Standard packaging: PE bag + carton, with custom packaging available

• Compliant with international transportation standards, protecting both dimensional accuracy and surface coatings

• Lead time:

☉ 7–10 days for small batches

☉ 15–30 days for mass production

We provide dedicated one-to-one service for global customers requiring CNC stainless steel turned parts.
