Hydraulics & Pneumatics Inspection

Manufacturers of mission-critical hydraulic and pneumatic parts and assemblies used in aviation, automotive and machine automation can inspect for burrs, defects, surface finish irregularities, and more, even inside deep or narrow bores. Hawkeye Precision Borescopes allow fast, reliable visual inspection inside complex machined parts and through very small openings that could never be seen with the naked eye.

These new rigid videoscopes have all the features and excellent optical quality of Hawkeye Pro Rigid Borescopes, and deliver the image quality of video, built right into every scope!

  Luxxor Video Systems
The Luxxor Video System can be used with any Hawkeye Borescope, and any laptop or desktop computer. Video and still images can be captured, stored, documented, and emailed. 
  Hawkeye Pro Slim 180 mm
The Pro Slim offers the best combination of small diameter, length, and bright illumination. Most machined metal parts afford ample access for the Hawkeye Pro Slim borescope and 90º mirror tube.

Quality EDM

Nobody in the EDM business likes having a customer reject parts because of hidden flaws. Mike Gervais, president of Quality EDM in Anaheim Hills, CA, {manufacturer of hydraulic manifold, hydraulic valve, hydraulic cylinder and other hydraulic component parts} hated it so much that he bought the quality control equipment that his customers used. Today Gervais has a policy of 100% inspection, using Hawkeye® Precision Borescopes. He has not only improved the quality of parts delivered to customers, but has also reduced scrapped parts. "Inspecting carefully during setup minimizes scrap later. This is an important part of cost control for us, since we're working with very expensive parts," says Gervais, who estimates the annual cost savings run to thousands of dollars. Hydraulic repair and hydraulic service facilities also find the Hawkeye borescope a valuable tool to diagnose problems before a major tear down of equipment.
