Precision Grinder

Description

A Precision Grinder with advanced experience in precision grinding operations and process development. This role is responsible for grinding high-precision ball screw components while developing and maintaining processes capable of achieving extremely tight dimensional and surface finish requirements. The ideal candidate will understand the impact of outside processing and material conditions on final grind geometry and performance. 

• Set up, program (where applicable), and operate precision grinding equipment including cylindrical, centerless, thread, and surface grinders
• Develop grinding processes for precision ball screw components and related assemblies
• Analyze engineering drawings and process requirements to determine grinding strategy and stock allowances
• Compensate for dimensional variation resulting from heat treatment, coating, plating, and prior machining operations
• Establish wheel selection, dressing parameters, and grinding sequences for optimal part quality
• Perform detailed dimensional and surface finish inspections
• Troubleshoot grinding issues including taper, chatter, burn, geometry variation, and surface finish defects
• Collaborate with engineering and quality personnel on process capability and continuous improvement initiatives
• Maintain process documentation, setup sheets, and inspection records
• Mentor less experienced machinists and operators
• Ensure compliance with all quality and safety requirements 

Requirements

Minimum Qualifications:

• Strong understanding of cylindrical, centerless, and thread grinding processes
• Experience grinding hardened precision components to micron-level tolerances preferred
• Ability to develop and optimize grinding processes
• Strong blueprint reading and GD&T interpretation skills
• Knowledge of heat treat distortion, stock allowance planning, and material behavior 

Minimum Competencies:

• 5+ years of precision grinding experience in a high-tolerance manufacturing environment
• Experience with advanced inspection methods and precision gauging
• Strong troubleshooting and process improvement skills
•  Ball screw, aerospace, bearing, or motion-control manufacturing experience preferred
