Wire & Sinker EDM Machinist

Join Our Team at Bullen Ultrasonics - Where Precision Meets Innovation

Are you ready to put your EDM expertise to work in a role where precision, problem-solving, and process improvement come together? At Bullen Ultrasonics, you will do more than run equipment. You will help shape dependable machining processes, solve challenging production issues, and share your knowledge with the people who bring those processes to life every day.

As our Wire and Sinker EDM Machinist, you will set up, program, and operate both sinker and wire EDM equipment to create high-quality parts and tooling to exact specifications. This role places special emphasis on sinker EDM process development while continuing to support wire EDM work as an important part of the position. When trained and needed, you may also support related machining processes, including Ultrasonic Machining.

Join a team grounded in excellence, humility, integrity, and teamwork. At Bullen, your experience, ideas, and contributions are valued.

Put your skills to work in a specialized machining environment where precision, process development, creative problem-solving, and continuous improvement matter.

Help turn challenging machining requirements into reliable, repeatable processes while supporting production employees and delivering high-quality results for our customers.

Work in an environment where safe practices, clean work areas, responsible machine care, and a commitment to quality are essential parts of how we operate.

• Plan the Work:
  Review drawings, work instructions, customer specifications, and inspection requirements, then plan complete sinker and wire EDM setups.
• Program with Precision:
  Program wire and sinker EDM operations using machine controls, standard programming methods, and approved CAM software, including Mastercam.
• Dial In the Process:
  Select and adjust machining parameters, offsets, cutting strategies, and finish passes to achieve required dimensions, tolerances, surface finishes, quality, and productivity.
• Own Wire EDM Setups:
  Manage wire loading or threading, start-hole preparation, flushing, alignment, and recovery from wire breaks.
• Develop Sinker EDM Setups:
  Handle electrode installation, centering, orbiting or offset strategy, dielectric flow, and electrode wear compensation.
• Build Better Processes:
  Develop, optimize, troubleshoot, and document sinker EDM processes on Makino equipment.
• Create the Right Tools:
  Prepare, inspect, identify, and maintain electrodes, tooling, fixtures, work holding, and setup components. Create or modify tooling and fixture designs from part drawings and coordinate needed materials.
• Verify the Results:
  Inspect completed work using calipers, micrometers, indicators, and other required measurement devices.
• Solve Problems Together:
  Partner with operators, engineering, quality, management, and vendors to resolve process, tooling, electrode, equipment, or quality issues.
• Share Your Expertise:
  Train production personnel on approved sinker EDM processes, setup practices, and operating requirements.
• Keep Work on Track:
  Complete production, inspection, setup, maintenance, and quality documentation accurately and on time.
• Care for the Equipment:
  Perform routine machine care and preventive maintenance, protect materials and tooling, and maintain clean and safe work areas.
• Support Related Operations:
  Operate surface grinders, belt sanders, hole-making equipment, and multi-axis drilling equipment when trained and authorized. Apply applicable Bullen Quality Management System procedures and support Ultrasonic Impact Grinding or other machining processes as needed when trained.
