What is Facing and Centering Machine?
FCVN Series Facing & Centering Machines Precihole manufactures a special purpose, highly versatile machine for facing and chamfering barrel blanks. Accuracy in these operations is critical for the barrel blank to be located and aligned properly in the cone clamping system on gun drilling and pull reaming machines. If the barrel is improperly faced or chamfered, the barrel does not seat properly in the cone leading to inaccuracies in the gun drilling operation. This machine engages the component simultaneously at both ends. The combined facing and chamfering operation use a special tool that ensures high productivity. Two hydraulically operated self-centering work holding vices hold the barrel blank accurately. Total cycle time is generally less than 30s. Automation for loading and unloading barrels can be added as an option on the machine.
