The Senior Walter CNC Tool & Cutter Grinder is responsible for operating and maintaining Walter Helitronic CNC tool grinding equipment to manufacture high-precision cutting tools. This role involves machine setup, program adjustment, inspection, and continuous quality control to ensure tools meet exact print and performance requirements.

Location: Little Rock, AR

Employment Type: Full-Time

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.

• Set up, program, and operate advanced CNC tool & cutter grinders (Primarily Walter Power machines with Tool Studio Software)
• 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

• 7+ years of CNC tool and cutter grinding experience (high precision environment)
• Strong expertise in multi-axis CNC grinding (5-axis preferred)
• Advanced understanding of:
  • Tool geometry, cutting theory, and material science
  • Grinding wheel selection, dressing, and coolant optimization
• Proven ability to work with tight tolerances in a production or job shop setting
• Experience reading and interpreting complex technical drawings
• Proficiency with measurement and inspection tools
• Strong problem-solving skills and attention to detail
• Ability to work independently with minimal supervision

• 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

• Competitive compensation based on experience and skill level
• Overtime opportunities
• Stable, long-term employment with growth potential
• Opportunity to work on challenging, high-value tooling projects

This is not an entry-level or routine production position. We are looking for someone who:

• Takes pride in precision craftsmanship
• Can solve complex tooling problems without hand-holding
• Understands the impact of tooling on overall manufacturing performance
• Wants to be recognized as a technical expert
