A positive-feed drill motor assembly includes a positive-feed motor, a gearbox, and a drill-bit. The positive-feed motor includes the spindle which rotates around a spindle axis and simultaneously translates in a direction parallel to the spindle axis. The gearbox includes a plurality of gears rotated by the spindle. The plurality of gears is configured to engage and rotate a drill-bit around a drill-bit axis which is offset from the spindle axis. The gearbox and a drill-bit attached thereto are configured to simultaneously translate with the spindle in the direction parallel to the spindle axis as the spindle rotates around the spindle axis.

The present disclosure provides exemplary collapsible drills and associated methods of use. Thus, in one aspect, the disclosure provides a collapsible drill including or comprising a chuck, a piston and a motor section. The chuck can be configured and dimensioned to receive a drill bit. The piston can include a pair of interlocking splines. The motor section drives rotation of the piston and the chuck. Depression of the piston can stop rotation of the chuck relative to the piston. In another aspect, the disclosure provides methods of drilling into a material that include providing a collapsible drill, driving rotation of the piston and the chuck with the motor section, and depressing the piston to stop rotation of the chuck relative to the piston.

A method of forming a batch of uniformly shaped glass sheet objects is disclosed. A stack of glass sheets is placed in a frame and submerged in a coolant. A hole is drilled through the stack. The cores of the hole and any debris from the drilling process are swept away in the coolant and pumped through a filter. A pin is inserted into the hole and attached to the base. A head on the pin, or a washer, fixes the stack of glass to the base at the hole. An outer profile is then cut in the glass stack around the hole while the formed objects are held to a base of the frame by the pin. Again, any debris is swept away in the coolant. The uniformly shaped objects are removed from the frame and separated. The glass sheet objects are preferably usable as a substrate for a magnetic or magneto-optical (MO) data/information storage retrieval medium.

A tool for removing burrs detects whether the depths of holes (81, 82, 83) made on a work (W) are prescribed depths or not. The tool (30) for removing burrs includes a tool case (31) and a piston (3) stored to move to and fro in the tool case. The piston has a spindle (12) arranged at its leading end. A judging section (61) judges whether the depth of the hole is normal or not, based on the results of the detection of whether the piston is retracted relatively to the tool case by a piston position detecting mechanism (56) and those of the detection of existence of the tool case by the tool case position detecting means (32).

Spindle assemblies with inline direct drive feed are disclosed. In one embodiment, a manufacturing system includes a support structure configured to be positioned proximate a workpiece, a carriage moveably coupled to the support structure, and a head assembly coupled to the carriage. The head assembly includes a spindle assembly, comprising a feed unit and a spindle unit. The feed unit includes a feed motor coupled to a drive mechanism, the feed motor and the drive mechanism being disposed along a longitudinal axis of the spindle assembly. The spindle unit has an aft end operatively coupled to the drive mechanism of the feed unit, the spindle unit including a fluid-driven motor coupled to a tool collet chuck, the spindle unit being configured to translate along the longitudinal axis by actuation of the feed motor.

A tool is provided for use in at least one of drilling, tapping, back spot facing and counter-boring at least one hole. The tool includes a servo motor cutting device and a gearbox. The servo motor cutting device and gearbox rotate a cutting tool to create the hole. A drill unit skid is adapted to engage a hook fit slot in the case of the dynamoelectric machine and supports the servo motor drill and gearbox.

The present invention is a coring unit adapted to be engaged to an articulated arm, to reduce the labor necessary for on-site coring of sewage and water pipes. The coring unit includes a frame containing the components of the unit, which include a coring bit, a coring bit motor, a traverse mechanism, and a stabilizer for allowing ready orientation of the coring unit with respect to an object being cored. The unit may also be provided with a traverse motor for driving the coring bit into an object being cored, and for withdrawing the coring bit once a core has been formed. The coring unit may additionally be adapted to allow for remote operation of the coring unit.

A pelletizing machine for forming pellets from extruded material includes an extruder having at least one exit port and a body defining a cutting chamber through which high-temperature liquid flows, flooding the cutting chamber. The exit port of the extruder opens into the cutting chamber, which includes a cutting section defining a flow path for liquid through the cutting section. A cutter in the cutting section of the cutting chamber is mounted for rotation about an axis generally perpendicular to the first direction and disposed for cutting the extruded material exiting the exit port into the pellets. The axis of rotation of the cutter is parallel to or coincident with the flow path of the cutting section. A method for forming pellets of thermoplastic material with a foaming agent is also disclosed.

Methods and systems for concentric clamping for manufacturing assemblies are disclosed. In one embodiment, a drilling assembly includes a spindle assembly configured to perform a drilling operation at a drilling location on a workpiece, and a clamping assembly having an actuator concentrically disposed about the spindle assembly. A nosepiece is coupled to the actuator and is configured to apply a clamping force concentrically about the drilling location on the workpiece. The actuator may include an inner housing having an outwardly extending flange, and an outer housing disposed about the flange of the inner housing. Pressurization of a first chamber moves the inner housing forwardly and applies the clamping force of the nosepiece against the workpiece, and pressurization of a second chamber moves the inner housing aftwardly and retracts the nosepiece away from the workpiece.
