Disclosed is a method for machining a component, comprising: installing the component on a fixture, causing a medium of the fixture to solidify to encase a first portion of the component, applying a toolset to a second portion of the component that is outside of the solidified medium, and subsequent to applying the toolset, extracting the component from the fixture when the medium is in one of a liquid state or a semi-liquid state, where the medium has a melting-point temperature that is less than 500 degrees Fahrenheit. Disclosed is a fixture for machining a component, comprising: a medium configured to encase a first portion of the component when the medium is in a solidified state, and a toolset configured to be applied to a second portion of the component that is outside of the solidified medium, the medium having a melting-point temperature that is less than 500 degrees Fahrenheit.

According to various embodiments, a workpiece planarization arrangement may include: a chuck including at least one portion configured to support one or more workpieces; and a planarization tool configured to planarize the at least one portion of the chuck and to planarize one or more workpieces on the at least one portion of the chuck; wherein the at least one portion of the chuck includes at least one of particles, pores and/or a polymer.

According to various embodiments, a workpiece planarization arrangement may include: a chuck including a support carrier; and a workpiece-support replaceably mounted on the support carrier; and a planarization tool configured to planarize the at least one portion of the workpiece-support and to planarize one or more workpieces on the at least one portion of the workpiece-support.

A clamping apparatus includes: locking members (80) insertable into a hole (11) of a workpiece (10); and a clamp rod (70) configured to make a wedge engagement with the locking members (80) from above. Each locking member (80) includes a base portion (85) configured to be inserted into the hole (11); and a protruding portion (87) located above the base portion (85). A relative movement restriction mechanism (M) configured to restrict downward movement of the clamp rod (70) relative to the locking members (80) within a predetermined travel distance allows descent of outer peripheral surfaces (85a) of the base portions (85) relative to an inner peripheral surface of the hole (11) when the locking members (80) are in a diameter-expanded position.

A blocking tool and a method of using the blocking tool to sand a surface of a vehicle are disclosed. The blocking tool includes a first member having a length and having an outer periphery with a plurality of cuts formed therein. The plurality of cuts extend over at least about 70% of the length and each of the cuts penetrates the first member through an arc of at least about 70% of the outer periphery. The blocking tool also has a base member with a first surface, an oppositely aligned second surface, and a length. A portion of the outer periphery of the first member is secured to the first surface of the base member to form an integral blocking tool.

The invention discloses a multi-set clamping fixture for diamond machining, which is used for machining diamonds. The clamping fixture includes a base shell, a lip ring, and a sealing ring. The upper end of the base shell is opened, the lip ring is arranged at the inner ring position of the base shell, an embedding groove is arranged at the inner ring position of the lip ring, the sealing ring is arranged in the embedding groove, a vacuum cavity is formed in the base shell, and the base shell is externally connected with a vacuum pumping pipeline. After the pavilion portion of a diamond to be machined is inserted into the lip ring and supported by the sealing ring, a vacuum cavity is formed in the base shell, the vacuum cavity is vacuumized by the external pipeline, and then the diamond is limited at the position of the lip ring to complete the clamping process. The lip ring is connected with the base shell in a detachable structure. An annular air pressure cavity is arranged on the outer edge of the upper portion of the base shell, one ends of a plurality of auxiliary clamping rods are located in the air pressure cavity, and one ends of the auxiliary clamping rods radially pass through the inner annular surface of the air pressure cavity and the lip ring to be in contact with the diamond. Shaft seals are arranged at the positions where the auxiliary clamping rods pass through the inner annular surface of the air pressure cavity, and the clamping fixture further includes a cavity cover that is mounted on the upper portion of the base shell and covers and wraps the air pressure cavity. The air pressure cavity is internally connected with an external pressure air source pipeline.

A method for fabricating vacuum tooling is disclosed using porous granular media. A sheet of steel webbing is affixed to a frame. A plurality of layers of fiberglass is affixed to the webbing. A vacuum port is installed through the webbing and plurality of layers of fiberglass. A granular media is mixed with epoxy to form a granular mixture. The granular mixture is layered over the plurality of layers of fiberglass to form a flat surface and machined for uniformity before sealing.

A device (1) for the movement of sheet-like pieces (P) in a machine tool (M), including a frame (10) moving towards or away from the machining surface (P1) of the machine, a gripping device (20) including a sheet-like element (21) with a gripping surface (21a) having openings (24) and mounted on the frame (10) rotatingly around at least one axis (x) substantially orthogonal to the direction of movement (D) of the frame (10) and element for the creation of a vacuum (25) communicating with the openings (24) and adapted to generate a vacuum pressure at the openings (24), which, when the gripping surface (21a) is substantially next to the machining surface (P1), makes it possible to detach the pieces (P) from the machining surface and keep them on the gripping surface.

The present disclosure relates to a fixing device arranged to be fastened to a machining head such as a drill head. A machine tool for machining workpieces such as metal sheets at a machining point is also disclosed. The workpieces may be machined from a machining side. A fastening device is included and adapted for fastening the fixing device to the machining head. A fixing head is included and adapted for releasably, locally fixing the workpiece on its machining side and adjacent to the machining point.
