Description

Clamp for aligning and setting points in electric spark machining

Technical Field

The utility model relates to the technical field of machining clamps, in particular to a clamp for aligning and setting points in electric spark machining.

Background

Spark machining is a non-conventional machining method used in metal machining that uses the manner of spark discharge to cut or machine a metal workpiece into a desired shape. In the electric spark machining process, aligning the set point is one of the very important steps.

Alignment of the set point in the electric discharge machining refers to determining a specific position on the surface of the workpiece as a reference point before machining starts, so as to accurately control the electrode position during machining.

1. Accurate positioning: the alignment set point ensures that the electrode is accurately positioned at a particular location on the workpiece for discharge in accordance with the desired machining path. This can avoid errors and offsets, ensuring accuracy and precision of machining.

2. Workpiece consistency: there may be minor dimensional differences in a batch of workpieces. By aligning the set points, the electrode position can be adjusted according to the actual characteristics of each workpiece, thereby ensuring that each workpiece obtains consistent processing results.

3. Avoiding damage: if the setpoint is not properly aligned, the electrode may discharge at the wrong location, resulting in the workpiece being improperly machined or damaged.

4. Efficiency is improved: the alignment setting point can reduce the times of adjustment and correction in the processing process, thereby improving the production efficiency and saving the time.

In summary, the alignment of the set point is a key step for ensuring accurate machining in the electric spark machining process, and ensures the machining accuracy, consistency and efficiency.
