Custom CNC Turn-Mill Machining Parts for Automation Equipment

Precision 304 Stainless Steel Components with Knurling and Thread Machining for Industrial Applications

YS Precision specializes in custom CNC turn-mill machining services for industrial automation equipment manufacturers, producing complex mechanical components with high accuracy, consistent quality, and reliable repeat production capability.

For this project, YS Precision manufactured a custom 304 stainless steel mechanical component according to the customer's engineering drawings.

The component was designed for an automation equipment application and required multiple precision manufacturing processes, including:

• CNC turning
• CNC milling
• Thread machining
• Precision knurling

The combination of rotational features, threaded sections, and functional grip surfaces required careful process planning to ensure dimensional accuracy and consistent performance.

After production, each component was inspected according to the customer's 2D drawings to verify that critical dimensions met the specified requirements.

Approximately 1,500 pieces were manufactured and exported to a European customer.

Due to stable quality and reliable delivery performance, YS Precision continues to support repeat production as the customer's equipment demand grows.

Project Overview

Complex CNC Turn-Mill Machining for Automation Components

Automation equipment requires mechanical components that combine:

• Precise dimensions
• Reliable assembly performance
• Long service life
• Stable production quality

This stainless steel component contains multiple functional features, including:

• Precision turned cylindrical surfaces
• Threaded connections
• Knurled anti-slip surfaces
• Stepped diameters
• Internal machining features

Manufacturing this type of component requires more than standard CNC turning.

YS Precision utilizes CNC turn-mill machining technology to integrate multiple operations into a controlled production process.

This reduces:

• Multiple setups
• Alignment errors
• Production variation

while improving:

• Accuracy
• Repeatability
• Manufacturing efficiency

Why CNC Turn-Mill Machining Was Used

For complex mechanical components, maintaining the relationship between different features is critical.

Using separate turning and milling operations may create challenges such as:

• Additional fixture setups
• Positioning deviation
• Longer production cycles

With CNC turn-mill machining, YS Precision combines:

Turning Operations

Used for:

• Outer diameter machining
• Cylindrical surfaces
• Precision stepped features

Milling Operations

Used for:

• Functional slots
• Flat surfaces
• Additional machining features

Thread and Surface Operations

Including:

• External thread machining
• Internal feature processing
• Knurling

This integrated process improves overall part consistency.

Precision Knurling for Functional Mechanical Components

The knurled area is a key functional feature of this component.

Unlike decorative patterns, industrial knurling requires accurate control to achieve:

• Reliable grip performance
• Consistent pattern depth
• Uniform appearance
• Stable production quality

During manufacturing, YS Precision controls:

• Knurling pressure
• Surface condition
• Dimensional influence after knurling
• Batch consistency

This ensures every component provides the expected mechanical function.

304 Stainless Steel CNC Machining Expertise

304 stainless steel is widely used for automation equipment components because of its:

• Excellent corrosion resistance
• Mechanical durability
• Long-term stability
• Good appearance after machining

However, stainless steel machining requires careful process control because of:

• Higher cutting resistance
• Tool wear
• Heat generation

YS Precision optimizes:

• Cutting parameters
• Tool selection
• Machining sequence
• Inspection frequency

to maintain stable production quality.
