Machinist I

SCOPE: The Machine Operator – SNK Horizontal (3-Axis) is responsible for operating CNC equipment in accordance with ISO 9001 quality standards to produce precision components and welded assemblies used in fire apparatus manufacturing. This role ensures product conformity through proper setup, fixturing, inspection, documentation, and adherence to controlled processes. The operator plays a key role in maintaining quality, traceability, and continuous improvement within the manufacturing process.

ESSENTIAL FUNCTIONS:

Machine Operation & Setup (ISO 9001: Operational Control)

• Operate an SNK horizontal 3-axis CNC machine in accordance with approved work instructions, setup sheets, and CNC programs.
• Perform machine setups for welded assemblies and fabricated components, identifying and establishing key reference points (datums) to ensure the assembly remains square, parallel, and accurately sized.
• Verify correct tooling, fixturing, offsets, and programs prior to machining.
• Ensure all production activities are performed under controlled conditions as required by ISO 9001.

Fixturing & Tooling (Process Consistency & Control)

• Select, install, and verify fixturing and tooling to ensure part stability and repeatability.
• Develop, modify, or assist in creating tooling or fixtures as required to meet part and quality requirements.
• Ensure tooling and fixtures are maintained, identified, and used as intended to prevent nonconforming output.

Engineering Interpretation & Product Requirements

• Read and interpret engineering drawings, blueprints, specifications, and work instructions.
• Distinguish between plate-welded assemblies and straight pull-off machining requirements.
• Identify key characteristics, datum references, and critical tolerances impacting product conformity.

Measurement, Inspection & Quality Assurance (ISO 9001: Monitoring & Measurement)

• Perform first article inspections to validate setup accuracy prior to production release.
• Measure parts using calibrated inspection equipment such as calipers, micrometers, height gauges, and bore gauges.
• Verify product conformance to drawing specifications and key tolerances.
• Accurately complete required inspection and quality documentation to support traceability and audit requirements.

Production Monitoring & Nonconformance Control

• Monitor machining operations to ensure ongoing compliance with quality requirements.
• Make approved offset or parameter adjustments to maintain dimensional accuracy.
• Identify, segregate, and report nonconforming product in accordance with the Nonconformance Control Procedure.
• Participate in corrective and preventive action activities when required.

Programming Support (Preferred Skill)

• Edit existing CNC programs and offsets following approved change control procedures.
• Preferred: Ability to create or program new CNC code to support new parts, tooling, process improvements, and design changes in compliance with ISO controls.

Safety, Documentation & Continuous Improvement

• Follow all safety policies, PPE requirements, and lockout/tagout procedures.
• Maintain accurate records related to production, inspection, and quality activities.
• Support continuous improvement initiatives by identifying process inefficiencies, quality risks, and improvement opportunities.
• Maintain a clean and organized work area consistent with 5S and ISO expectations.

REQUIRED SKILLS & QUALIFICATIONS

Education

• High school diploma or equivalent required.
• Technical or vocational training in machining or manufacturing preferred.

Experience / Technical Skills

• CNC machine operation experience required; large horizontal machine experience preferred.
• Experience machining welded assemblies in a fire apparatus or heavy manufacturing environment preferred.
• SNK machine experience strongly preferred.
• Strong understanding of fixturing, tooling, and process control.

• Ability to properly align and zero welded assemblies.
• Proficiency in first article inspection and tolerance verification.
• Understanding of ISO 9001 requirements related to production, inspection, and documentation.

Aptitude

• Strong mechanical aptitude and attention to detail.
• Ability to fabricate or modify tooling while maintaining process control.
• Commitment to quality, consistency, and compliance.

Physical Requirements

• Ability to stand for extended periods.
• Ability to lift up to 40 lbs with or without assistance.
• Ability to work safely in a manufacturing environment with moving equipment and fabricated metal components.
