Master Cut EDM, which offers superior CNC small hole EDM services, recently put its leading-edge technology to work to manufacture toothbrush molds. On this project, Master Cut turned to its precision electrical discharge machining to hole-pop the undersized, starter holes, and then used its Fanuc wire EDMs to finish each hole to the final dimensions specified by the client.

Shock-resistant S-7 tool steel, which was created for high-impact resistance at relatively high hardness, was chosen for this project. Master Cut EDM ensured the product met the tightest tolerances of +/-.0001″ and performed the necessary in-process testing and inspections using Go and No-Go gauges. There were 3 different styles of toothbrush and we produced 1,280 holes per each 32 cavity mold. 24 inserts, which were 45 lbs. each, were machined over a two-week period for in-state delivery to our client.

We present additional information on this project below and look forward to discussing your firm’s requirements.
