Key Responsibilities and Required Skills for a Machine Builder

🎯 Role Definition

A Machine Builder is a highly skilled technical professional responsible for the complete assembly, integration, and testing of custom automated machinery and complex electromechanical systems. This role serves as the crucial link between engineering design and a fully functional, commissioned machine. Working from detailed blueprints and schematics, the Machine Builder meticulously assembles mechanical components, installs pneumatic and hydraulic systems, and wires electrical panels and devices. They are expert problem-solvers, tasked with debugging and resolving issues that arise during the build and power-up phases, ensuring the final product meets exacting quality standards and design specifications before it is delivered to a client.

Core Responsibilities

Primary Functions

Execute the complete mechanical assembly of custom, automated machinery from the ground up, strictly adhering to complex engineering blueprints, 3D models, and assembly drawings.
Perform high-precision fitting, alignment, and calibration of critical components such as linear motion guides, ball screws, servo motors, and robotic end-of-arm tooling.
Install, plumb, and test pneumatic and hydraulic systems, including routing tubing and hoses, mounting valves and cylinders, and ensuring leak-free, functional operation.
Build and wire machine control panels, operator consoles, and junction boxes from detailed electrical schematics, ensuring all wiring is neat, labeled, and adheres to safety standards.
Mount and wire all machine-level electrical devices, including sensors, motors, safety switches, light curtains, and vision systems.
Conduct initial machine power-up procedures and perform comprehensive I/O checks to verify that all electrical components are correctly wired and communicating with the PLC.
Systematically debug and troubleshoot mechanical, pneumatic, hydraulic, and electrical issues encountered during the build and testing phases, documenting and resolving each problem.
Collaborate directly with Mechanical and Controls Engineers to provide critical feedback on designs, identify potential assembly issues, and suggest improvements for manufacturability and serviceability.
Utilize a wide array of hand tools, power tools, and precision measurement instruments, such as calipers, micrometers, dial indicators, and torque wrenches, to ensure assembly accuracy.
Perform basic machining and fabrication tasks using manual lathes, milling machines, grinders, and drill presses to modify or create brackets, spacers, and other components as needed for the build.
Manage the build timeline for assigned projects, ensuring key milestones are met and quality standards are maintained throughout the entire assembly and testing process.
Interpret and apply Geometric Dimensioning and Tolerancing (GD&T) specifications from drawings to guarantee precise fit and function of assembled parts.
Participate in Factory Acceptance Testing (FAT) by running the machine through its operational sequences to validate performance against design criteria, often in the presence of the customer.
Prepare completed machinery for shipment, which may involve partial disassembly, securing components, building custom crates, and completing shipping documentation.

Secondary Functions

Travel to customer facilities for on-site installation, final commissioning, and Site Acceptance Testing (SAT) of the equipment.
Maintain a clean, organized, and safe work environment by following all company safety protocols and embracing principles like 5S.
Diligently document the build process, including "red-lining" prints and schematics with any modifications or corrections made during assembly for as-built records.
Assist in managing project-specific inventory, conducting parts counts, and communicating with the purchasing department to ensure all necessary components are available.
Actively participate in design review meetings, offering practical, hands-on insights to improve the robustness, reliability, and ease of assembly for future machine designs.
Mentor and train junior builders or apprentices, sharing technical knowledge, best practices, and troubleshooting techniques.
Support the Field Service department by providing technical expertise and troubleshooting assistance for issues on machines already deployed at customer sites.
Contribute to the company's continuous improvement goals by identifying and recommending enhancements to build processes, tooling, and fixtures.
