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.

A holder for holding a plurality of parallel-arranged tubular members includes a first block and a second block, configured to hold the plurality of tubular members between the first and second blocks. The first block includes a plurality of first grooves formed in a surface thereof that faces the second block, the first grooves each extending in a direction in which the tubular members extend, and each of the first grooves has a semicircular shape when the first block is viewed from the direction in which the tubular members extend.

Provided is a liquid circulation device for a machine tool including a tank which has an introduction portion and a lead-out portion of a liquid, and in which a liquid circulated between the liquid circulation device and the machine tool is stored; and a heat exchanger disposed in the tank, in which the tank has a throttle portion in which a cross-sectional area of a liquid passage between the introduction portion and the lead-out portion is reduced and a first storage portion on the introduction portion side from the throttle portion, and at least a portion of the heat exchanger is disposed between a center of the first storage portion and the throttle portion.

Machining apparatus for machining a chilled workpiece include a support surface that supports the chilled workpiece during machining by a machining tool of the machining apparatus, and further include a cooling system operatively coupled to the support surface. The cooling system prevents a machining temperature of an adhesive coupled to the chilled workpiece from rising beyond a predetermined threshold temperature during machining of the chilled workpiece, such that the cooling system prevents curing of the adhesive during machining of the chilled workpiece. The cooling system includes a cooling fluid that radiantly cools the chilled workpiece via the support surface while the chilled workpiece is supported by the support surface, such that the cooling system maintains the machining temperature of the adhesive (and of the chilled workpiece) below an ambient temperature. Related methods include machining the chilled workpiece using such machining apparatus.

A motor controller comprises: a motor driver arranged at a housing attached to a machine support; fan motors and arranged in or outside the housing; and a control unit. The motor driver drives motors. The fan motors blow cooling air for cooling the interior of the housing. The CPU includes a machining mode selection unit allowing selection of at least either a first machining mode of machining a machining target finely or a second machining mode of machining the machining target more roughly than in the first machining mode. If the first machining mode is selected, the machining mode selection unit exerts control to change the rotation numbers of the fan motors and so as to reduce vibration to be transmitted from the housing to the support column.

A rotary table for a machine tool comprising a stator unit, a rotor unit rotatable at least about a rotational axis, wherein the rotor unit comprises at least one receiving unit for the reception of a workpiece, a first bearing unit for the mounting of the rotor unit in the stator unit, and an electromagnetic motor drive for the motorized driving of the rotor unit. The rotor unit, at least in the region of the motor drive and/or of the first bearing unit, has at least one rotor-cooling apparatus, comprising a cooling medium and at least one cooling surface, for the cooling and/or absorption of waste heat from the motor drive and/or from the first bearing unit.

A machining process includes providing a cutting tool having a rake face and a flank face; bringing the cutting tool into contact with a metal alloy work piece to form a chip by penetrating the cutting tool into the workpiece; and introducing a nanofluid into a vicinity of the penetration to remove heat and, in some instances, customize the finished surface. The nanofluid includes a mixture of a cryo-liquid and nanoparticles having a maximum size of approximately 0.1 nanometers to approximately 100 nanometers.
