Machinist

Job Title: Machinist

Job Description

This role requires an experienced machinist who can independently set up and operate a variety of machine tools, interpret complex blueprints, and perform precise calculations to produce high-quality components. You will act as your own process engineer and programmer at the machine, using your knowledge of G-code, feeds and speeds, and geometric dimensioning and tolerancing (GD&T) to ensure parts meet specifications and quality standards.

Responsibilities

• Perform shop math including addition, subtraction, multiplication, division, and geometric, algebraic, and trigonometric calculations to support machining operations.

• Carry out metric conversions accurately to interpret drawings and specifications in different measurement systems.

• Read and interpret blueprints, specifications, and GD&T symbols to determine part requirements, tolerances, and machining sequences.

• Set up and operate vertical lathes, horizontal lathes, boring bars, and mills, including vertical mills, to produce precision components.

• Calculate appropriate feeds and speeds for various materials and tooling to optimize efficiency and tool life while maintaining part quality.

• Apply a strong understanding of geometric tolerancing to ensure parts conform to dimensional and positional requirements.

• Use calipers and other precision measuring tools to verify dimensions and ensure parts meet specifications throughout the machining process.

• Edit G-code directly at the machine to refine programs, adjust toolpaths, and correct issues, functioning as your own programmer and process engineer.

• Utilize conversational controls when available to create or adjust programs at the machine (experience with conversational controls is considered a plus).

• Handle large parts, often 20 inches or more, safely and efficiently, including assisting with rigging and overhead crane operations when needed.

• Monitor machine performance, identify issues, and make adjustments to maintain quality and productivity.

• Maintain a clean, organized, and safe work area in accordance with shop standards and safety procedures.

• Collaborate with team members and leadership to meet production schedules, support continuous improvement, and ensure on-time delivery of customer orders.

Essential Skills

• Ability to perform shop math including addition, subtraction, multiplication, division, and geometric, algebraic, and trigonometric calculations.

• Ability to perform accurate metric conversions for machining and inspection tasks.

• Minimum of 5+ years of setup machining experience, with flexibility to consider candidates with less experience who demonstrate a strong attitude and aptitude.

• At least 3+ years of experience reading blueprints and applying GD&T in a production environment.

• Proficiency in reading and interpreting blueprints, specifications, and geometric tolerancing requirements.

• Strong understanding of geometric dimensioning and tolerancing (GD&T).

• Experience with G-code and M-code, including editing programs at the machine.

• Hands-on machining experience with vertical lathes and horizontal lathes.

• Experience operating vertical mills and horizontal lathes, including Haas cells or similar equipment.

• Skill in using calipers and other precision measuring tools for inspection and verification.

• Ability to calculate feeds and speeds for various materials and tooling.

• Capability to act as your own process engineer/programmer at the machine, without relying on an in-house programmer.

Additional Skills & Qualifications

• Experience with conversational controls is a plus.

• VTL (vertical turning lathe) experience is highly desirable.

• Experience with boring bars is preferred.

• Rigging experience with an overhead crane is a plus, especially for handling parts 20 inches or larger.

• Familiarity with horizontal machining operations and large contract machining environments.

• Comfort working with Haas cells consisting of vertical mills and horizontal lathes.

• Strong problem-solving skills and a proactive, positive attitude toward learning and continuous improvement.
