A muntin bar fabrication system can be used to efficiency produce a wide variety of different types of muntin bars, allowing the fabrication of both standard and custom muntin bar assemblies for doors, windows, and other fenestration products. In some examples, the fabrication system includes a muntin bar stock storage assembly that holds multiple different types of muntin bar stock. The system also includes a muntin bar stock extraction device that extracts one of the different types of muntin bar stock from the storage assembly and conveys the extracted muntin bar stock to a feed device. The feed device feeds the extracted piece of muntin bar stock into a cutting system that includes a multi-axis cutter. The cutting system that performs one or more cutting operations on the extracted muntin bar stock so as to fabricate one or more individual muntin bars from the extracted muntin bar stock.

The machining method uses a tool to machine a workpiece set in a jig, the workpiece has a plate-like web part arc-shaped in plan view and a flange part bent and arranged vertically from an edge along the arc shape, the tool has an end cutting edge and a peripheral cutting edge, and the jig has a surface where the web part is placed and a contacting surface where the flange part comes into surface contact. The machining method includes: pressing the flange part against the contacting surface; cutting the flange part by the peripheral cutting edge by feeding the tool in an arc direction of the arc shape; and cutting the web part by the end cutting edge by feeding the tool in the arc direction.

A hand-held power-tool device is described as including at least one intermediate shaft, which is formed as a planet wheel carrier and includes a plurality of planet wheel receptacles and planet wheel bearing points situated in the circumferential direction. It is provided that the intermediate shaft includes at least one material recess at least in the area of at least one planet wheel bearing point on its outer circumference.

An automatic milling machine mills a gasket. The automatic milling machine controls the position of a cutter head relative a table. The automatic milling machine rotates the gasket with a motor. Parameters of the motor are monitored to determine the amount of rotation of the gasket.

Provided is a machining center, in particular a 5-axis milling machine, for machining an elongate workpiece, in particular a turbine blade, including an elongate machine bed extending in a longitudinal direction, a machining device movably retained on the machine bed, two clamping devices, which are retained on the machine bed in such a way that the clamping devices lie opposite each other in the longitudinal direction and which are designed to clamp the free ends of the workpiece and to rotate the clamped workpiece about a workpiece axis of rotation, wherein at least one clamping device can be moved in the longitudinal direction of the machine bed and at least one clamping device has a drive device designed to rotate the clamped workpiece, in particular a stepper motor, and a steady rest, which is retained on the machine bed and positioned between the clamping devices.

This processing device is provided with: a tool for machining a workpiece W along the thickness direction thereof, the width-direction external shape of the workpiece W being substantially finished; and a flexible vice 7 that clamps the workpiece W in the width direction without clamping the workpiece W in the thickness direction. The flexible vice 7 is provided with a position adjustment mechanism that prevents the position of the workpiece W from changing in a plane along the width direction before and after the workpiece W is clamped. The present invention is provided with a rough processing tool for performing processing at a rough-processing position, a finishing processing tool for performing processing at a finishing-processing position, and a control unit that causes the position adjustment mechanism to move between the processing performed by the rough processing tool and the processing performed by the finishing processing tool.

A machining apparatus capable of performing chamfering with high precision is provided. A machining unit 13 is provided at a distal end portion 12a of an arm 12 of an articulated robot 11, and the machining unit 13 includes a profiling roller 57, which serves as a roller that abuts against a part to be profiled Wd of a workpiece W, and a rotatable tool 41 having an axis line 41a having a distance between the rotatable tool 41 and the profiling roller 57 in conformity with a width of the workpiece W (width of a band-like portion Wc) and extending in parallel with an axis line 57a corresponding to a support axis of the profiling roller 57, and the rotatable tool 41 includes cutting blades 41b or blade portions 73 and 73 as chamfering blades.

A pipe coating material removal apparatus, comprising a support frame, a subframe, and one or more coating material removal members. The subframe is supported by the support frame and is configured to rotate relative to the support frame at least partially around a subframe rotation axis. The subframe rotation axis is configured to be substantially coaxial with a longitudinal axis of a pipe to which the apparatus may be applied in use. The, or each, coating material removal member is rotatably mounted to the subframe to remove part of an exterior coating of a pipe. The apparatus is configured such that the one or more coating material removal members enable the removal of pipe coating material at orientations substantially parallel to, and inclined with respect to, the longitudinal axis of the pipe.

A method for machining ribs or grooves on a shaft (7) with an axial bearing (24) forming part of the shaft. The ribs or grooves (32, 24a) are obtained on a workpiece portion of the shaft and of the axial bearing, by moving the shaft or at least one tool holder fitted with a machining tool in a longitudinal direction of machining, by the tool performing reciprocating motions with a position in contact and with a position not in contact with the shaft or the axial bearing from the beginning to the end of the workpiece portion or face. The reciprocating motions are synchronised with the sinusoidal programming carried out in the machining unit, along with the desired and programmed arrangement of the ribs or grooves to be produced.
