Electric graver handpiece

A graver handpiece for engraving, the graver handpiece comprising:

• a solenoid configured to generate a magnetic field when energized;
• a plunger positioned adjacent to the solenoid;
• and
• a spring configured to impart a spring force on the plunger,
• wherein the plunger is configured to accelerate away from an intermediate impact device under a force imparted on the plunger by the magnetic field of the solenoid, and
• wherein the plunger is configured to strike the intermediate impact device with a forward end of the plunger transferring at least a portion of the force to the intermediate impact device.

A method of operating a graver handpiece, the method comprising:

• receiving a drive pulse by a solenoid;
• generating a magnetic field by the solenoid based on the drive pulse;
• imparting a force onto a plunger by the magnetic field;
• estimating an impact time of the plunger;
• eliminating the magnetic field at or near the impact time based on an input from a hand control or a pedal;
• and
• forcing the plunger away from an intermediate impact device by a spring force from a spring coupled to the plunger.
