摘要:
A sealing device for sealing a leakage flow on a machine element, which is circular in cross section, of a working machine includes a housing, which has an upstream end and a downstream end and through which the machine element extends, an upstream pressure chamber which is arranged at the upstream end of the housing, a downstream pressure chamber which is arranged at the downstream end of the housing, and a sealing element which is arranged between the upstream pressure chamber and the downstream pressure chamber. The sealing element is mounted within the housing and rests sealingly against the machine element. A bypass line runs around the sealing element and fluidly connects the upstream pressure chamber to the downstream pressure chamber. A throttle element designed to reduce the pressure of a flowing leakage fluid by a predetermined pressure difference is arranged in the bypass line.

Disclosed is an artificial tooth machining apparatus which protects a workpiece and first and second tools from heat and frictional contact that may occur when the workpiece is machined and enhancing machining precision by supplying water or air to the tools by a supply unit, a first nozzle portion, and a second nozzle portion, which has a lifespan lengthened by preventing chips of the workpiece or water or air from being introduced to a mechanism operation part of a base part by a discharge unit and a blocking unit, and which prevents a collision between the first tool and the second tool during machining of the workpiece by a tool collision preventing controller.

The wear status of a micro-endmill tool may be inferred by monitoring the chip production rate of the tool in operation. Chips may be extracted from a work area, captured on an adhesive surface, imaged, and counted to determine the chip production rate. When the rate of chip production falls, the feed rate of the micro-endmill may be modified to a level suitable for the current state of tool wear. In this manner, costly and inconvenient work stoppages to evaluate the wear status of a tool are eliminated.

A method of manufacturing a transmission case housing is provided wherein a minimum quantity of lubrication as a compressed air/oil mist is supplied as the housing is rough bored and face milled. The transmission case defines a plurality of transmission fluid drainage holes for draining transmission fluid from the transmission when installed in a vehicle. The housing is positioned with the fluid drainage holes below a central axis of the housing and a plurality of internal bores and faces are bored and face milled on the housing. The compressed air/oil mist is sprayed from the cutting head to cool and lubricate the boring and face milling tools. Machining chips are blown off the rough bored housing through the fluid drainage holes.

The present disclosure shows a centrifugal station for removing a machining fluid from workpieces, comprising a workpiece mount which is set into rotation by a drive to liberate a workpiece which is received in the workpiece mount from adhering machining fluid. In this respect, the centrifugal station has a compressed air cleaning arrangement which removes machining fluid adhering to a region of the workpiece by blowing with compressed air. The present disclosure furthermore comprises a corresponding compressed air cleaning arrangement for the removal of a machining fluid from geared workpieces, wherein the compressed air cleaning arrangement removes machining fluid adhering in a region of the workpiece by blowing with compressed air.

There is provided a workpiece separation apparatus permitting input of a mixture of workpieces and chips stably within a flow current and separating them accurately and efficiently. The workpiece separation apparatus includes an input cylinder inserted within a separating container, and a fluid supplying means arranged so as to supply fluid to the separating container from a part lower than a lower end of the input cylinder, and configured such that the fluid overflows and flows out of the upper end of the separating container due to a flow current generated within the separating container, and such that the level of the fluid rises up in the input cylinder and the fluid does not flow out of the upper end of the input cylinder, but is maintained substantially in a resting state and at a level above the level of the upper end of the separating container.
摘要:
A residue remaining on an object to be cleaned after cleaning is easily detected and observed on the object. Adhesive materials 2A and 2B for use in residue confirmation, which are applied in advance to an object 1 to be cleaned for confirmation of a residue remaining on the object 1 after cleaning, are formed by coloring chips produced during cutting work. The adhesive materials 2A and 2B are preferably formed by coating and coloring the chips with paint, the paint emitting visible light in an excited state.
