摘要： 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.

摘要： This invention relates to cutting tools used to machine materials to produce new surfaces and chips of removed material. Embodiments of this invention allow round rotating cutting inserts to be used in a more economical way, with improved accuracy, with improved sealing, and with greater ease of use. The rotary support device and cutting inserts may be used in either radial or tangential mounting types of cutters. It also provides a built-in, fully sealed means of fine adjustment of the cutting insert that is useful in some applications.

摘要： The invention relates to a stop for a rotating drilling, milling or countersinking tool which comprises a stop sleeve which is freely rotatably coupled, by means of a sliding or rolling bearing, around the tool. A first bearing bush of the bearing supports the stop sleeve. A second bearing bush of the bearing sits in a rotationally fixed manner on a shaft sleeve. The shaft sleeve can be pushed and fastened on a shaft of the tool. In a secondary aspect, the invention relates to a drilling, milling or countersinking tool having such a stop.

摘要： A device and method for holding a bit for a tool. The holding device, which is secured to a support surface, includes a housing having a base, a first leg and a second leg. A slot is defined between the first and second legs and the shank of the bit is received through one of a plurality of differently dimensioned apertures defined along the slot between the first and second legs. An adjustment assembly is engaged with the first and second legs and is movable to a first position to clamp the shank in the selected aperture; and is movable to a second position to release the shank. When the adjustment assembly is moved from the second position to the first position, a free end of the second leg bends toward the first leg, thereby reducing the diameter of the aperture within which the shank is received.
