TOOL PRESETTING DEVICE

摘要

A tool presetting device for longitudinally presetting an end cutting tool in a tool holder for use in a single or multiple spindle automatic bar machine characterized in that the device has a tool holder support which non-rotatably holds the tool holder in a predetermined axial position for axial adjustment of the tool to engage a preset micrometer which is clamped in one end of a micrometer holder. The other end of the micrometer holder is frictionally swingably retained in a selected groove of a grooved bar which is parallel to the tool holder and tool for swinging movement of the micrometer in a plane perpendicular to the tool holder and tool axis from a position laterally clearing the tool holder and tool for axial insertion and removal of the tool holder and tool from the tool holder support to a position whereat the end of the tool may be axially advanced with respect to the tool holder for engagement with the micrometer. The grooves in the bar provide for adjustment of the micrometer holder in 1" increments while the micrometer provides for precise adjustment from .000 to 1.000".
