The latest addition to our precision engineering capabilities is a Sunnen MBB-1660 small hole hone. With a diameter range of 0.0600 to 6.5000in (1.50 to 165mm) the hone can be used to refurbish hydraulic directional control spool valves, or even brake and clutch cylinders from all types of vehicles.
The addition of this small bore honing capacity complements our larger horizontal hone, increasing our honing capability from under 2mm up to 500mm in diameter with the ability to upgrade to 1000mm diameter if required.
