The disclosure relates to a holder system for supporting sports equipment. The holder comprises a vise assembly comprising: a vise base; two moveable vise jaws provided with respective vise screw bores and guide bores, the two moveable vise jaws engageable with a first section on the sports equipment; a vise screw extending substantially horizontally through the vise base and oppositely disposing the movable vise jaws through the vise screw bores, and having two sections of threads allowing for movement of the movable vise jaws, the two sections being separated by a thread-free section; and one or more guide bars fixed in a substantially horizontal orientation in the vise base and extending through the respective guide bores.

A clamping device for holding a workpiece, in particular a cutting tool, during machining in a grinding machine, wherein peripheral grinding of the workpiece is performed by means of a particularly approximately cup-shaped grinding wheel, wherein the clamping device comprises a support unit provided to be mounted on the grinding machine, a clamping unit comprising a clamping anvil supported in a clamping anvil holding element and translationally drivable to apply a clamping force parallel to a clamping axis, and a drive unit comprising a drive anvil supported in a drive axis and rotationally drivable for rotary orientating the workpiece by means of the drive axis. The clamping unit and the drive unit are provided as individual components, which are releasably or slidably attached to the support unit to form a workpiece spindle headstock of the grinding machine.

Disclosed are vise embodiments designed to lower manufacturing cost and work well in an automated CNC milling production environment. The disclosed embodiments include rigid vises having high clamp force and low internal friction. The embodiments include features for resisting the ingress of metal chips into sensitive moving parts through the use of commonly available seals and the flow of CNC coolant to flush metal chips away from the vise.

A power vise including a body and a jaw connected to and extending from the vise body. The vise can also include an actuator extending at least partially through the jaw body, where the actuator can include a first end and a second end opposite the first end. The vise can include a moving jaw connected to the first end of the actuator. The vise can include a motor connected to the second end of the actuator, where the motor can be operable to move the actuator to move the moving jaw with respect to the fixed jaw, including a hammering or impacting function, and that such hammering or impacting can be performed after a predetermined delay. The vise can include a sensor configured to produce a signal based on a condition of the vise and to control the vise at least in part on using that signal.
