Description

Technical Field

[0001] The utility model relates to the technical field of instrument production, in particular to a universal end face clamping device for a three-axis machining center. Background Art

[0002] When processing the surface of instruments and meters by a three-axis machining center, the workpiece needs to be fixed.

[0003] However, the proposals in the prior art use traditional vise clamps to clamp and fix the instrument and meter housings. First, the clamping force is difficult to control, so that the clamping force on the workpiece is different each time.
