PREFACE
Each PCNC 440 ships with a Cercate of Inspecon. This report details each of the quality assurance
measurements performed at the factory by a Tormach quality assurance team member prior to
approving shipment of each machine.
A sample cercate of inspecon and more informaon on quality assurance measurements is
available at: hp://www.tormach.com/quality_overview.html
In pracce, accuracy and repeatability are heavily inuenced by the techniques used by the
machinist. A skilled machinist can oen deliver accuracy that exceeds the accuracy specied by
the machine builder, while an inexperienced machinist may have diculty delivering the expected
accuracy. With this understanding, we cannot tell you what accuracy you will be able to achieve in
your own work. Nevertheless, the accuracy specied by a machine builder remains an important
reference point.
