Precision Component Cleaning and Inspection Solutions

Industry Challenges

Precision manufacturing — including AT, DCT, and CVT shafts, gears, and small precision components — requires cleanliness levels far tighter than general industrial parts. Even trace machining oil, fine metal particles, or micro-burrs can cause premature wear, noise, or failure in high-precision transmission and gear systems. At the same time, mixed gear types or undetected surface defects can create serious downstream assembly and safety risks.

Manufacturers need cleaning systems capable of ppm-level cleanliness on small, high-value components, paired with vision inspection that verifies both part quality and part identity before assembly.

Solution Overview

Our precision manufacturing solutions combine ultrasonic and automated cleaning systems with vision inspection technologies designed for small, high-precision components.

Cleaning Solutions:

Our cleaning systems handle AT, DCT, and CVT shafts and gears using ultrasonic cleaning, spray cleaning, and automated basket/batch cleaning systems. For standard small and medium-small components, our 6-axis waterproof robotic cleaning systems deliver adjustable pressure cleaning tailored to component size and geometry.

Vision Inspection Solutions:

Our vision inspection systems verify dimensional accuracy and part identity on precision components. Using automated geometric dimension inspection and bin picking verification, our systems detect dimensional deviations and confirm correct gear types before parts move to assembly.

Supported Components

Our precision manufacturing solutions cover a wide range of transmission and small precision components:

Core Applications:

Transmission components: AT shafts & gears, DCT shafts & gears, CVT shafts & gears
Structural components: subframes
Standard components: small and medium-small precision parts (100 g–20 kg)

Case Studies

Case Study 1: Standard 6-Axis Robotic Cleaning Machine for Small Precision Components

We designed and delivered a standard 6-axis robotic cleaning machine for small precision components, using a waterproof 6-axis robot to handle workpieces ranging from 100 g to 10 kg with customizable cleaning pressure and cycle time. The system integrates adjustable filtration and temperature control, supporting both room-temperature and heated cleaning up to 60℃.

Key Results:

Cycle time: 60–90 seconds (customizable)
Cleaning precision: 1 mg/kg
Filtration precision: 10 μm–50 μm
Cleaning pressure: 0.25–2 MPa (customizable)
Maximum robot load: 34 kg; workpiece weight range: 100 g–10 kg

This standardized system supports flexible, repeatable precision cleaning across a wide range of small component types and production volumes.

Case Study 2: Vision Inspection System with Bin Picking Verification for Gears

We deployed a vision inspection system for a precision gear manufacturer to address the risk of gear surface defects and type mixing during production. The system verifies correct gear type output alongside surface quality, preventing incorrect parts from reaching the transmission assembly line.

Key Results:

Correct gear type verification integrated with bin picking
Reduced risk of transmission failure from mixed or defective gears

The system supports safe, reliable gear sorting and quality verification for high-precision transmission manufacturing.

FAQ

Q: What cleanliness levels can your systems achieve for precision shafts and gears?

A: Our standard robotic cleaning systems achieve cleanliness levels as low as ≤ 1 mg/kg, with particle size control down to 10-50 μm, suitable for high-precision transmission components.

Q: How do you clean AT, DCT, and CVT shafts and gears differently?

A: We match the cleaning method to the component and volume requirements — ultrasonic cleaning, spray cleaning, or automated batch/basket cleaning — to ensure consistent oil and particle removal across different shaft and gear types.

Q: Can your vision inspection systems prevent incorrect gear types from reaching assembly?

A: Yes. Our vision inspection system with bin picking verification confirms correct gear type output alongside surface defect detection, reducing the risk of transmission failures caused by mixed parts.

Q: What size range of components can your standard robotic cleaning systems process?

A: Our standard systems handle components from 100 g up to 20 kg, using 6-axis waterproof robots with adjustable cleaning pressure from 0.25 up to 45 MPa depending on the system configuration.

Q: How long does it take to commission a custom precision cleaning or inspection system?

A: Timelines depend on system complexity and integration requirements. Our project management team supports you from planning through production handover for efficient commissioning.
