A workholding system includes an adjustable vise, a fixed vise, and a fixture plate. The adjustable vise and the fixed vise are secured to the fixture plate using a T-slot and a fastener. The system includes multiple precision locating surfaces, including interchangeable precision locating surfaces, to secure a working part. In one embodiment, a T-slot fastener facilitates the creation of an entire workholding system that facilitates the rapid installation of studs into receiving members. The fastener includes a quarter turn fastener used in workholding applications to quickly hold and release components of the system, such as tooling, parts, and plates. The compact design of the system makes possible the ability to insert the quarter turn fastener into a device that can fit into a T-slot and still have considerable holding power. The system is lower in cost than other solutions.

A saw slide device allows a user to easily and accurately move a saw for proper alignment with a cutting material or workpiece. The saw slide device generally includes a sliding plate configured to support an associated saw, an adjustment or alignment mechanism configured to move the sliding plate, and a base frame which supports the sliding plate and adjustment mechanism.

A hydraulic control circuit operable to selectively hydraulically link first and second hydraulic actuators and to bypass that hydraulic link.

The present application relates to a machining assembly comprising an effector intended to be mounted on a robot with multiple degrees of freedom, in which invention the mounting of the motor spindle relative to the intermediate supports and frame of the effector allows a numerically controlled movement along three axes X, Y, Z of a trihedron, the effector bearing on the piece to be machined or on the surrounding tools by means of a ball joint at the foot end of the effector. Since the effector bears on the piece to be machined or on the surrounding tools it is possible to create local stiffness and to obtain the precision required to guarantee the quality of the machining process.

A clamper mechanism for a motion guide device includes a clamper block having tapered faces, clamper rolling elements arranged between the tapered faces and both left and right side faces of a track member, and a clamper rolling element holder attached to the clamper block with an interposition of an elastic member. When an elastic force exerted by the elastic member acts in a direction in which the clamper block and the clamper rolling element holder are separated from each other, the clamper rolling elements bite the tapered faces to bring the clamper block into a state restrained to the track member. When an external force against the elastic force exerted by the elastic member acts, the clamper rolling elements are brought into a free state within the tapered faces to bring the clamper block into a state not restrained to the track member to exert a stable clamping force.
