Multi-axis machining head

TL;DR: A milling head for a milling machine arranged for machining large-size workpieces comprises a fork 18, which is rotatably arranged around a first axis (C) and demonstrates a pair of fork arms (21, 22 ), which are separated from one another, a spindle device (23), arranged between the fork arms and rotatable around a second axis A, a first torque motor (42), which is coupled to the fork 18 for directly driving and controlling of the rotation of the fork around the first axis C, and a second torque motor( 57 )

TL;DR: In this article, a direct drive spindle assembly including a main fork formed by a base and a parallel pair of spaced fork arms and rotated about a first rotational axis is described.

TL;DR: In this article, a milling machine includes a bi-directional, variable speed, rotary workpiece holding table, a table drive sized to achieve relatively high acceleration and deceleration rates, a cutting tool mounted to a single or dual axis head, and a control system adapted to achieve a high degree of tool position and table rotational position accuracy cooperating to permit high-speed machining operations, including substantially dome-shaped parts characterized by circumferential surface portions interrupted by radial wall portions.

TL;DR: In this article, a spindle unit has a tilt shaft for rotating and tilting a spindles head so that a posture of the spindle can change with the tilt shaft, and the output shafts of the drive source devices are arranged to face the side walls and connected to the power transmission mechanisms.

TL;DR: A milling and drilling head for a machine tool has an input shaft housed in a stationary case also incorporating a control means drivingly connected to a ring gear which is fast with a moving case portion accommodating at least one tool holding spindle driven off the master spindle of the machine tool and being set at an angle to the X-axis thereof as mentioned in this paper.

TL;DR: In this paper, the rotary movement of the spindle head is derived from the drive shaft for a spindle sleeve, which can be arrested in the horizontal and vertical working positions by means of a support housing.

TL;DR: In this article, a machine system adaptable to a wide range of milling conditions and functions by the provision of a master milling head capable of providing spindle-driving power and up to 5-axis movement to a range of individual spindle heads each designed for a specific machining function, and each selectively, interchangeably, and automatically matable to the master head.

TL;DR: In this article, a machine tool includes a machine table for receiving a workpiece, a headstock disposed above the table, a turntable mounted on an underside of the headstock and being rotatable relative to the table about a vertical first axis.
