Step ring piece forming clamp
Technical Field
The utility model relates to the technical field of step ring clamps, in particular to a step ring forming clamp.
Background
In the step ring machining process, the step ring needs to be clamped and fixed, and the clamping can ensure the stable position of the step ring in the machining process, prevent the step ring from moving or deforming due to external force or machine tool vibration, and further ensure the machining precision. The stepped ring forming clamp is an auxiliary tool for fixing a material to be cut, particularly a stepped ring, and performing machining on a machine tool.
