Technical advantages:
ü Slipring's core technology - friction pair technology: gold metal contact
technology, ensuring an ultra long service life.
ü Mirror processing technology: Ensure that the smoothness of the
slip ring contact surface can reach Ra0.02, making the contact more
reliable.
ü Precision component manufacturing process: dimensional
tolerance<0.01mm, high precision, and more stable performance.
ü Advanced brush wire modulation technology: Nearly zero pressure
brush design and debugging process, extending the life of the slip
ring by 1/3.
ü Small in size and compact in structure, it can meet the space
constraints of users.
ü The slip ring adopts a solid aluminum alloy metal structure with
strong sealing performance, suitable for extremely harsh
environments.
ü High speed, customizable speed of 10000 revolutions per minute.
ü Long lifespan, 10 million revolutions per minute.
Manufacturing Process
- Precision Machining: Utilize advanced CNC machines (e.g., DMG MORI) to ensure
component accuracy with a tolerance of ±0.002mm.
- Automated Assembly: Conduct assembly in a Class 10,000 cleanroom, with robotic arms
guaranteeing consistent brush - ring alignment and contact pressure
control (0.1 - 0.5N).
- Surface Treatment: Apply a 3 - 5μm gold - plating layer through vacuum ion - plating
technology, enhancing conductivity and corrosion resistance.
Rigorous Testing
- Electrical Testing: Use Keithley 2000 multimeters to measure contact resistance and
Keysight signal analyzers to verify data transmission integrity.
- Mechanical Testing: Subject products to high - speed rotation tests (Magtrol HB -
1000) for up to 1000 hours and vibration resistance tests (Brüel
& Kjær) to simulate real - world conditions.
- Environmental Testing: Perform temperature cycling (-40°C to +120°C) and humidity tests
(95% RH) in a Weiss Technik climatic chamber to ensure reliability.
