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.
Features
-
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
Accuracy of transmission: ≤ 2 µm
Repeatability: ≤ 0,5 µm
