When the machine is brand spanking new. That way you have something to compare it to down the road, so you have a map of the machine. Also, if it does find a problem you can go to the dealer immediately and ask them to take care of your problem under warranty. Ballbar 5 Plot analysis and ballbar

End milling - An end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a complex surface contour.The depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes.

For machine shop operators considering milling machines, one of the most basic questions they have to answer relates to configuration: vertical or horizontal mill?The answer depends on the nature of the business—in particular the type and volume of work being done in the shop—but also cost, capabilities of the workforce, and the facility itself.

TYPES OF MILLING MACHINES KNEE-TYPE MILLING MACHINE Knee-type milling machines are characterized by a vertically adjustable worktable resting on a saddle which is supported by a knee. The knee is a massive casting that rides vertically on the milling machine column and can be clamped rigidly to the column in a position where the milling head ...
