Kowa Rotary Wiper

05 September, 2025

The Kowa Rotary Wiper is an innovative machine vision system specifically designed for use in machine tools. It enables reliable monitoring of machining processes – even under challenging conditions. This rugged system is resistant to water, oil, and debris, ensuring a consistently clear view into the interior of the machine.

PROTECTIVE LENS COATING

Sapphire glass with Kowa’s special water repellent coating resists scratches and repels moisture, oil, and residue.

HIGH SPEED ROTATION

Air-powered rotary wiper clears residue and materials for a consistently clear view.

AIR INJECTION

High-pressure air not only rotates the wiper but also assists in removing moisture and oil.

Compact All-in-One Solution

The Rotary Wiper combines camera, lens, and housing in a compact unit. The front sapphire glass is scratch-resistant and features a special coating that effectively repels moisture, oil, and dirt. The glass is set into rotation using compressed air, while particles are simultaneously blown away from the outside. This keeps the view unobstructed – even in environments with heavy splash water or contamination.

Typical Application: CNC Machines

CNC machines often contain areas that are difficult to access visually – and this is where the Rotary Wiper excels. Thanks to high-resolution real-time imaging, potential issues such as chip accumulation can be detected early. This helps prevent damage to equipment and avoid costly downtime. Continuous monitoring during operation eliminates the need to stop machines for inspections. This increases productivity, reduces the risk of failure, and ensures smooth and uninterrupted manufacturing processes.

Benefits of the Rotary Wiper system in CNC machines:

See blind spots usually undetectable from outside of the CNC machine environment.
Quickly detect possible manufacturing issues before they happen such as steel chip accumulation.
Monitor live manufacturing and record data to ensure consistent results and improve production.
Monitor and assess manufacturing without the need to stop the CNC machine.
Compact size and easy to install.
