Employment Type:

Full-Time

About the Role

We are seeking a highly skilled Senior CNC Tool & Cutter Grinder to join our precision manufacturing team. This is a top-tier, hands-on technical role responsible for producing, sharpening, and maintaining complex cutting tools with extreme accuracy and consistency. The ideal candidate is a true craftsperson with deep experience in multi-axis CNC grinding, tooling geometry, and tight-tolerance work.

You will operate as a subject matter expert, working independently on advanced grinding projects while also supporting process improvement, training, and high-complexity tooling challenges.

Key Responsibilities

+ Grind, recondition, and manufacture precision cutting tools including:

+ End mills, drills, reamers, form tools, and custom geometries

+ Interpret complex engineering drawings, CAD models, and tool specifications

+ Develop and optimize grinding programs for efficiency, accuracy, and tool life

+ Perform in-process and final inspections using:

+ Micrometers, optical comparators, tool pre-setters, and CMMs

+ Maintain extremely tight tolerances (often within ±0.0001" to ±0.0002")

+ Troubleshoot tooling issues and refine processes to improve performance

+ Collaborate with engineering and production teams on tooling design and application

+ Ensure adherence to quality standards, including ISO and customer-specific requirements

+ Mentor junior grinders and support skills development within the team

+ Maintain equipment, tooling, and work environment in top operating condition

+ Strong problem-solving skills and attention to detail

+ Ability to work independently with minimal supervision

Preferred Qualifications

+ Experience with ANCA, Walter, Studer, Rollomatic, or similar CNC grinding platforms

+ Programming experience (G-code, conversational, or proprietary CNC systems)

+ Background in aerospace, medical, automotive, or high-precision tooling industries

+ Knowledge of CAD/CAM software for tool design (e.g., Mastercam, NX, or similar)

+ Lean manufacturing or continuous improvement experience

What We Offer

+ Competitive compensation based on experience and skill level

+ Overtime opportunities

+ Comprehensive benefits package (medical, dental, vision, 401(k))

+ Stable, long-term employment with growth potential

+ Opportunity to work on challenging, high-value tooling projects
