A portable helical milling unit has a tool, an eccentric spindle, an outer sleeve, a sleeve housing, and a plurality of transmission mechanisms used to provide power. The eccentric spindle is detachably provided in an output section of the outer sleeve. Each of the eccentric spindle and the outer sleeve has a pre-set eccentricity. The tool is in connection with an eccentricity adjustment mechanism. The outer sleeve is installed in the sleeve housing. The outer sleeve is in connection with a first transmission mechanism and a third transmission mechanism. The eccentric spindle is in connection with a second transmission mechanism. All eccentric spindles have the same shape, can be installed in the outer sleeve and can be quickly replaced, so as to achieve precise and large-range adjustment of the eccentricity, thereby expanding the aperture range of processed holes, and improving processing quality and efficiency.

A method of manufacturing a shim for a die coater is disclosed herein. In some embodiments, a method of manufacturing a shim for a die coater, where the shim is applied to an electrode slurry die of the die coater and used for discharging an electrode slurry from the die coater, comprising milling a surface of a metal plate to prepare the shim. Using the method herein, it is possible to manufacture a shim for a die coater having a low thickness deviation by processing the shim for a die coater through a milling process.

The desktop milling machine with an ovate-shaped bridge is a desktop milling machine of the computer numerical control (CNC) type having a portion of the bridge or frame structure configured to alleviate bridge deflections and deformations that are caused during the high-speed milling processes. Preferably, the bridge has an ovate arch, or has a rear face having an ovate contour.

Apparatus that is particularly suited for machining hard dense ceramic materials comprises a vertical milling machine within an enclosure. The machine has a plurality of slides for moving a spindle holding an end mill in the x, y, and z directions. The x and y slides are located above the elevation of the work table and any workpiece held thereon. Air flows downwardly from the region of the x and y slides and through gaps associated with two fabric shields which have horizontal portions that translate respectively in the x axis and y axis directions. The shields inhibit coolant that contains work piece particulates from traveling upwardly toward the x and y slides. A tool changer system comprises a tool holding tray (30) mounted adjacent the work table within a housing having a movable cover. The housing enables the tool tray to be removed from the enclosure through an access door while the machine tool is operating and coolant is flowing.

A debris control apparatus comprising a debris control enclosure, the enclosure further comprising a vacuum opening in the enclosure. The vacuum opening being sized, shaped and positioned to receiving a vacuum conduit, connected to a vacuum source, for extracting the debris from the enclosure. The debris control apparatus further comprising a mounting assembly for mounting the enclosure to a machine, such that, during operation, the enclosure moves along the work material as the cutting tool moves along the work material, the enclosure being mounted independent of movement of the cutting tool in and out of the work material. The mounting assembly comprises a depth adjuster for adjusting the operating depth of the enclosure. The depth of the enclosure can be adjusted such that the debris will be contained in the enclosure during operation.
