A drum sander having a fin for deflecting airflow around the drum and directing dust and debris to a dust collecting outlet. The fin includes a first section at a first angle and a second section at a second angle that directs air movement generated by the operating drum toward the dust collecting outlet. The free edge of the fin is shaped to wrap partially around the drum in two helical inclined planes. A tool free adjustment of parallelism may be provided. The workpieces are pulled through the sander rather than being pushed through. Lightweight materials reduce stress on the assembly. Heat is dissipated by the configuration and material of the drum.

The protective cooling cover comprises a hollow shell defining a generally semi-cylindrical cavity (15) that covers a portion of a cutting disc (2) at the top thereof and that is delimited by two lateral walls (11, 12) and a curved perimeter wall (13), a cooling device including a tube connected to a cooling liquid supply and to a cooling liquid projecting nozzle (31), and a fastening device for fixing the cooling liquid projecting nozzle (31) at different positions within the cavity (15) of the shell for projecting cooling liquid to different areas of the cutting disc, the fastening device including a plurality of first fasteners (17) connected to the periphery of the cavity, and a second fastener (32) connected to the cooling liquid projecting nozzle (31), the first and second fasteners (17, 32) providing a snap fit releasable connection.

A processing machine includes a chuck table, a chuck table cover having an opening through which a holding surface of the chuck table can protrude, a processing unit having a spindle, a spindle housing, and a mount portion arranged on a lower end portion of the spindle, the processing unit being configured to process a workpiece by a processing tool mounted on a lower part of the mount portion, a processing chamber construction cover that covers the chuck table and the mount portion. The processing machine further includes a processing tool cover that is secured to a lower end portion of the spindle housing and that has an upper wall and a side wall that extends downwardly from the upper wall. The processing tool cover is disposed inside the processing chamber construction cover and covers the processing tool from above and sides by the upper and side walls.

An angle grinder dust collection shroud includes mounting brackets which are attached to a shroud body via slots which allow the mounting brackets to move to different circumferential locations around the output shaft of the angle grinder as well and inwardly towards and outwardly away from the output shaft of the angle grinder. The mounting brackets are adjustable in their position around the angle grinder output shaft to allow them to engage the angle grinder while avoiding any mounting features for the angle grinder's stock blade guard.

A burnishing tool and a method of additively manufacturing components of the burnishing tool are provided. The burnishing tool includes a burnishing element for burnishing a workpiece. The burnishing element is positioned between an upper nozzle and a lower nozzle which are additively manufactured to define a plurality of internal fluid passageways for receiving, distributing, and discharging a burnishing fluid to facilitate cooling and/or lubrication of the burnishing element and/or the workpiece.

A chip suction cover is used for a machine tool including: a spindle configured to rotate a tool; and a suction mechanism unit configured to suck chips of a workpiece that are produced in accordance with rotation of the tool. The chip suction cover includes: a hollow body that is provided with an opening through which a rotation central axis of the spindle extends and that is arranged so as to surround the tool; and a cover body that is provided in the hollow body so as to partially close the opening and that is configured to cover a part of a tip end portion of the tool while exposing a remaining part of the tip end portion of the tool. A chip suction cover having such a configuration that improves the efficiency of sucking chips produced due to workpiece machining is provided.
