To compliment Barnes Bore Honing & Finishing Systems line of honing machines a complete selection of precision, self-centering bore gauges, all of them with interchangeable anvils and necessary accessories to perform close tolerance ID measurements is offered.
Measuring the diameter, roundness and conical form of a bore as well as the distances of plane-parallel surfaces.
Measuring head consists of a carbide-tipped moving anvil and an interchangeable stationary anvil which has a hardened steel ball (carbide is available)
Transmission lever system transfers movement of the moveable anvil to indicating instrument
The broad centering bridge ensures automatic centering in the bore
Insensitive to temperature due to both the shank and the transfer rod being made from heat resistant Invar steel
Highly resistant to wear and tear due to the carbide-tipped moving anvil
Constant measuring force due to built in spring eliminating user influence
Within this extensive modular system includes the following; measuring head, holder, extensions. Right angle attachments and depth stops
Accuracy of transmission: ≤ 2 µm
Repeatability: ≤ 0,5 µm
