The output at least partially supports therein the power tool bit. The chuck also includes an outer body having a cavity and rotatable relative to the output, and a lever coupled to the outer body and movable between a first position, in which the lever is at least partially retracted into the cavity, and a second position, in which the lever is extended from the cavity.

Abstract: A substrate holding apparatus comprises a substrate holding mechanism configured to hold a substrate; a heating mechanism; and a heat-conductive member which is interposed between the substrate holding mechanism and the heating mechanism to be in contact therewith and conducts heat generated by the heating mechanism to the substrate holding mechanism, wherein the heat-conductive member has a recessed section that opens to the substrate.

Abstract: A quick change tool chuck has a housing with an LED light source incorporated therein, the housing being coaxially located about a quick change driver bit chuck. The housing can have two LED lamps which are focused at the end of an associated bit.

Abstract: A locking tool or device that permits rapid installation and removal of a removable component from a component that is fixed to a housing or equipment. The interchangeable, and hence removable, components may be held in place by individual holders that provide secure axial locking means and quick radial removal means requiring no axial space for the removal of such components from the main base tool.

Abstract: In an automatic chuck jaw change system, a combined machining lathe capable of positioning with high precision and a robot with lower positioning precision than the combined machining lathe cooperate to automatically change a chuck jaw. The system includes a robot disposed in front of the combined machining lathe, and the robot can be selectively mounted on a front end of an arm thereof with a work hand for operating a work, a chuck jaw, and a nut runner hand for operating a drive mechanism of the chuck. The robot cooperates with a tool for jaw mounted on a tool spindle of the combined machining lathe to automatically change a chuck jaw of a main spindle.

Abstract: The present invention relates to a low-vibration tool holder (1) with a tool holder base body (2, 3, 4, 6) and a tensioning arrangement (5) which provides axial tensioning of the tool holder base body (2, 3, 4, 6) and which is simultaneously tensioned in a radially flexible way with respect to the tool holder base body (2, 3, 4, 6). This tool holder (1) is less susceptible to vibration than previously known tool holders, which ensures better true running even during operation and in particular when heat-induced expansion of materials occurs, since the clamping arrangement (5) which is integrated in the tool holder (1) is continuously centered with respect to the tool holder base body (2, 3, 4, 6). Furthermore, such a tool holder (1), in particular within a modular design, can be adapted very flexibly to different types of tools and workpiece machining processes.

Abstract: In a chuck for medical applications, including a housing having a passage extending axially therethrough with clamping elements movable supported in the housing together with a drive structure for moving the clamping element into and out of a clamping position for the engagement and release of a rotating tool, a space is provided around the drive structure for moving the clamping elements and flushing passages are provided for flushing out the space around the drive structure and, in the process, cleaning all the components of the chuck.

Abstract: A chuck for a processing machine (60) includes a connecting portion (101) extending into the processing machine (60), a head (11) and a flange (12) sandwiched between the head (11) and the connecting portion (101). A shoulder (122) is formed on a top face of the flange portion (12) to support thereon an annular pad (20) which is mounted around the connecting portion (101). A gap between the flange portion (12) and a bottom face of the processing machine (60) is compensated by an existence of the annular pad (20).

Abstract: A preferred embodiment of the invention comprises a tool chuck for a power hand tool of the type which has a generally cylindrical elongated housing with a motor contained within the housing or case and the motor having an output shaft that extends from the nose end of the hand tool, and which has one or more light producing devices located at its nose end for illuminating the work area during operation. The preferred embodiment of the tool chuck has an annular cylindrical light transmitting portion on the outside of the chuck body portion for transmitting light toward a tool bit held by the tool chuck. The preferred embodiment may have an inwardly oriented front end surface to direct the transmitted light toward the axis of the tool bit and may have an outer layer of resilient material to facilitate easy gripping of the tool chuck to tighten or loosen a tool bit.

Abstract: Anti-deflection tooling is provided for a pull back chuck. Equally spaced gussets are disposed between the riser body and the face plate of the chuck, to minimize or eliminate deflection of the face plate when a workpiece is clamped into the chuck. Adjustment devices are also provided so that existing chucks can be retrofitted with the anti-deflection tooling and an operator can true up the face plate prior to running a part.

Abstract: A method for providing the names of the city and state of a calling party to a called party when the calling party's name is unavailable. The method utilizes the calling party's telephone number to determine the names of the city and state from which the calling party is calling. The method incorporates a database that contains combinations of telephone numbers and the names of the cities and states that correspond to the various combinations of numbers. In response to an indication that the name of the calling party is unavailable, the method accesses the databases and searches for the matching telephone number and corresponding city and state names. If the names are found, they are delivered to the calling party.

Abstract: A spindle liner and spindle liner assembly are for use in a lathe. A quick-change feature allows the spindle liner to be readily installed and readily replaced with a new spindle liner. The spindle liner has a tubular sleeve with a set of annular bearing rings and an annular mounting flange. An adapter specially configured for mounting on a particular lathe is designed for use with the spindle liner. The adapter has an annular body with a center hole to allow the tubular sleeve of the spindle liner to be slid through it. A recessed shoulder around the hole has a diameter to accommodate the annular mounting flange of the spindle liner. The adapter also has at least one and preferably opposed retainer lugs extending inwardly from a peripheral edge of the annular body and overlying the recessed shoulder. An equal number of notches in the mounting flange of the spindle liner are positioned to align with the retainer lugs when the spindle liner is positioned in the lathe.

Abstract: A keyless tool chuck sleeve is provided for rotary tools which features an elastomeric cover integrally molded to the chuck sleeve to improve the operator's grip during opening and closing of the chuck. The chuck sleeve of the present invention further provides for an abrasion resistant nose, and bit centering and dust guard capabilities.

Abstract: A method of determining the minimum number of segments of a metal collet for a cutting tool holder having a truncated conical portion having a small-diameter end and a cylindrical portion connected to the small-diameter end. The collet is formed with slits extending axially inwards from the opening thereof for inserting a cutting tool and arranged at equal angular intervals. The slits extend to the cylindrical portion. The minimum number of segments is determined to be within the range where the geometrical moment of inertia of the section with respect to a line which passes through the centroid of the section and is perpendicular to a radical direction of the collet, as plotted against the number of segments, becomes substantially constant. With this arrangement, each segment has a suitable deflectability so that the collet can grip a cutting tool with sufficient force and accuracy and over a wide chucking range.
