A control system of a machine tool includes a hydraulic pressure adjuster. The hydraulic pressure adjuster includes a sequence program controller that includes components for adding a function of adjusting a hydrostatic pressure of a static pressure oil supplied to a hydrostatic pressure guide mechanism, which are a pressure setting unit, a constant acceleration motion controller, a workpiece-weight calculator and a supply state adjuster.

A mounting system having a dual plunger arrangement wherein the side of each plunger has a pull down cam to provide a desired pull down action in relation to at least two studs, the cams moving relative to one another and axially aligning relative to one another relative to the two axially spaced pull down studs to allow the plungers to provide a maximum hold down force for the two pull down studs, balance the hold down forces thereby maximizing performance and reducing unlocking forces.

Positionable block assemblies are described. Example block assemblies include a block body with a tooth surface and a plate member with a tooth surface. The tooth surfaces of the plate member and the block body are engageable to interlock the plate member with the block body. Further, the block body is engageable with the plate member at multiple different positions to enable precise positioning of a positionable block assembly to achieve a variety of different working scenarios.

A workholding apparatus for components having complex geometries or surfaces, which components are difficult constrain for the purpose of inspection, addresses the problem of adequately constraining such components in a convenient and cost-effective manner so that they do not move during inspection, while also making all or most critical features accessible to the inspection instruments being used. A method teaches how to eliminate setup changes between different components through the use of inexpensive modular attachments. These attachments are in the form of a single piece thermoplastic part which is affixed to each component having also reference features that can be interlocked into a common base fixture for more efficient inspection operations.

Disclosed is a tool length adjustment system which allows the tool length to be adjusted without removing the tool from the tool holder. The tool length can be adjusted through the combination of an external circumferential adjustment ring which can be rotated while the tool is in the tool holder, thereby driving an adjustment key built into the tool holder via the use of drive balls which ultimately cause the rotation of the adjustment key.

The adaption device is fastened to a workstation, and fixtures may be conveniently and reliably joined or detached from the adaption device. The adaption device mainly includes a main member having a number of sockets on a front side for mounting a fixture. Inside the main member, there are specifically-shaped blocks in an indentation of the main member, a shaft with dual sets of threads of opposite directions driving the blocks to move away from or towards each other, and rods in radially directional ducts driven by the blocks to move along the ducts into the sockets to lock the fixture 30 and automatically restored by elastic elements. A fixture as such may be conveniently, reliably, and precisely installed on a workstation through the adaption device, and the adaption device allows the manufacturing of products of large varieties to be conducted economically and efficiently.

A circular saw cutting machine (1) includes a machine main body (10), an articulated robot (60), and a cutter stocker (70). A circular saw (5) is secured and interposed by a cutter clamp cylinder (CYL21) between a front end face (32) of the main spindle (21) and a cutter presser piece (50) with pins (33, 51) inserted in pin insertion holes (5b). When removing the circular saw (5), a hydraulic is switched over to cause the cutter clamp cylinder (CYL21) to perform unclamping so that the cutter presser piece (50) can be pulled out of the main spindle (21). When the articulated robot (60) performs cutter change, a main spindle motor (M10) and a brake (25) are controlled based on the rotation angle detected by a spindle stop position sensor (SE10) to stop the main spindle (21) in a predetermined home angle condition.

A vise jaw combination used with a milling machine vise to hold a work-piece having either parallel edges or non-parallel edges. Wherein, the milling machine vise in this application disposes at least one movable member having threaded holes cooperating with fasteners to join the movable member and the vise jaw combination comprising a vertical axis tool post, a horizontal axis tool post, and a rotatable vise jaw. Wherein, the vertical axis tool post comprises a detachable wall disposing correlative thru holes for cooperating with the threaded holes and fasteners disposed at the movable member, whereby the vertical axis tool post is joined to the movable member disposed at the milling machine vise. Wherein, the horizontal axis tool post comprises a rectangular base disposing a thru hole for receiving a vertical shaft disposed at the vertical axis tool post, whereby the horizontal axis tool post is joined to the vertical axis tool post. Wherein, the rotatable vise jaw consists of a one-piece structure disposing a thru hole for receiving a horizontal shaft disposed at the horizontal axis tool post, whereby the rotatable vise jaw is joined to the horizontal axis tool post.
