摘要: 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.

摘要: 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.

摘要: A coated cutting tool for chip forming machining of metals includes a substrate having a surface coated with a chemical vapour deposition (CVD) coating. The substrate is coated with a coating having a layer of α-Al2O3, wherein the α-Al2O3 layer exhibits a texture coefficient TC(0 0 12)≥7.2 and wherein the ratio of I(0 0 12)/I(0 1 14)≥0.8. The coating further includes a MTCVD TiCN layer located between the substrate and the α-Al2O3 layer. The MTCVD TiCN layer exhibits a pole figure, as measured by EBSD, in a portion of the MTCVD TiCN layer parallel to the outer surface of the coating and less than 1 μm from the outer surface of the MTCVD TiCN, wherein a pole plot based on the data of the pole figure, with a bin size of 0.25° over a tilt angle range of 0°≤β≤45° from the normal of the outer surface of the coating shows a ratio of intensity within β≤15° tilt angle to the intensity within 0°≤β≤45° of ≥45%.

摘要: The invention relates to a method for introducing a balancing mark into the compressor wheel of a turbocharger. According to the method, a milling tool is firstly moved in a first direction in order to introduce a recess into the compressor wheel, and the milling tool located in the recess then runs out in a second direction in order to convert the recess into a pear segment-shaped balancing mark. The invention furthermore relates to a turbocharger which comprises a compressor wheel that has one or more pear segment-shaped balancing marks.

摘要: A support arrangement for supporting a workpiece at a processing device during processing of the workpiece. The support arrangement comprises: a fixating means adapted to arrange an abutment surface of the support arrangement in contact with one side of the workpiece when another opposite side of the workpiece abuts one or more fences of the processing device, a locking means adapted to lock the fixating means in a contact position where abutment surface of the support arrangement abuts the one side of the workpiece when another opposite side of the workpiece abuts the one or more fences of the processing device, and a connecting means adapted to connect the support arrangement with the processing device. The support arrangement may be applied e.g. at saw devices for fixating a log to be sawn, in order to achieve a satisfactory result for a sawing process, e.g. planks with a high dimensional accuracy it is important that the workpiece is reliably fixated during the sawing process.

摘要: A fully scalable turbomachine in which one or more of its components, in particular its bladed components, such as a blisk, is manufactured by controlled-fracture machining. The practical effects of the invention are (1) to improve the quality of current turbomachine components at greater rates of production and lower costs, (2) to increase the performance and the range of uses of current turbomachine functions, and (3) to enable new uses of turbomachines that are currently restricted by the lack of scalability and practicality in manufacturing. The most preferred embodiment of the invention is the gas turbine functioning as a jet engine or a turboshaft engine either for propulsion or for power generation.
