Core Responsibilities

Primary Functions

Set up, operate, and monitor single or multi-spindle tapping machines to perform a series of machining operations such as drilling, boring, and tapping internal threads in metal or plastic workpieces.
Interpret and work from complex engineering blueprints, technical drawings, and work orders to determine machining requirements, tooling, and operational sequences.
Conduct rigorous first-piece, in-process, and final inspections of all machined parts using precision measuring instruments like micrometers, calipers, thread gauges, and optical comparators to ensure conformity to specifications.
Select, install, and align appropriate cutting tools, attachments, accessories, and materials onto the tapping machine according to setup sheets and production requirements.
Adjust machine controls, speeds, and feeds to optimize performance and ensure parts are machined within specified tolerances.
Consistently meet or exceed established production targets and efficiency goals while maintaining the highest standards of quality and workmanship.
Troubleshoot machine malfunctions and operational issues, making necessary adjustments to resolve problems and maintain production flow.
Perform secondary operations such as deburring, cleaning, and finishing of tapped parts to prepare them for the next stage of production or assembly.
Monitor tool life and replace worn or broken taps, drills, and other cutting tools in a timely manner to prevent damage to parts and equipment.
Read and understand Geometric Dimensioning and Tolerancing (GD&T) symbols on blueprints to ensure parts meet critical dimensional requirements.
Perform routine and preventative maintenance on tapping machinery, including cleaning, lubricating, and making minor adjustments to ensure optimal performance and minimize downtime.
Continuously observe machine operation to detect defects or out-of-tolerance machining and adjust controls as required.
Manage workflow by prioritizing tasks based on production schedules, work orders, and instructions from supervisors.
Diligently adhere to all company safety policies, OSHA guidelines, and best practices to maintain a safe and hazard-free working environment for yourself and your colleagues.
Verify the conformance of finished workpieces to specifications, using various measuring instruments to check for accuracy of thread depth, pitch, and diameter.
Maintain a clean, organized, and efficient work area by adhering to 5S principles and good housekeeping practices.

Secondary Functions

Maintain accurate and timely production records, including logs for part counts, scrap, and machine downtime.
Actively participate in continuous improvement initiatives, such as Kaizen events, to enhance productivity and reduce waste.
Collaborate effectively with team leaders, quality assurance personnel, and engineers to resolve production issues and improve processes.
Assist in the training and mentoring of new or less experienced machine operators, sharing knowledge and best practices.
Carefully handle raw materials and finished components, ensuring proper storage and transport to prevent damage or contamination.
Provide support and guidance to junior operators, sharing knowledge and best practices for machine setup and operation.
