A manufacturing machine (100) for manufacturing a dental object (101), having a suspension damper (103) for slowing down the falling dental object (101).

A machining tool assembly is provided for machining a blank to form a firearm lower receiver. The assembly includes a pair of side plates positionable on opposed sides of the blank to capture the blank therebetween. A template plate having a template aperture is adapted to be removeably attachable to the side plates. The template aperture is aligned with a top surface of the blank and is adapted for machining a cavity within the blank having a peripheral contour complimentary to a peripheral contour of the template aperture. A centering mechanism is adapted to be removeably attachable to the template plate, with the centering mechanism including an opening aligned with a corresponding void formed on the blank to align the blank with the template plate.

An attachment for converting a CNC milling machine to a CNC wire saw machine. The attachment may include a gantry that may be coupled with a respective gantry of the CNC milling machine, a carriage that may be attached to and moveable with a respective carriage of the CNC milling machine. A drive pulley of the system may be coupled with and driven by a spindle of the CNC milling machine. The drive pully may drive a wire saw through an assembly of idler pulleys. A wire tension mechanism may keep the wire fully stretched. The wire tension mechanism may include a curved guide rail mounted on the gantry and a vertical guide rail mounted on the carriage. A slider that slides vertically on the vertical guide rail and follows the curved guide rail may house a tension wheel that may keep the wire at a fully stretched state.

A supporting device and method for a large thin-walled part is disclosed. The supporting device comprises a processing device and a supporting device. A workpiece is positioned between the processing device and the supporting device and is clamped at a periphery in a flexible clamping mode. A cutter in the processing device is connected with an iron core. A coil is wound on the iron core. When the coil is energized, a magnetic field is generated around the coil. A blade part of the cutter is in contact with a processing side of the workpiece. The supporting method combines the magnetorheological fluid technology with the jet supporting technology, and uses a jet impact force to offset part of a milling force. The current magnitude and winding mode of the coil are changed to control magnetic field intensity. The magnetorheological fluid is cured instantly to support the workpiece.

A position measuring device includes a scale carrier with a measuring scale. A scanner is configured to generate position signals by scanning the measuring scale. A processor is configured to process the position signals into a digital position value. An interface is configured to communicate with downstream electronics. At least one collision sensor is assigned to the position measuring device, and is configured to generate analog or digital measured values from a time characteristic of which collision events are determinable. The measured values are fed to an evaluator configured to determine the collision events by evaluating the time characteristic of the measured values in a controller.
