Field Service Technician — CNC Machine Tools

Position Summary

We are seeking an experienced Field Service Technician with a strong background in the service, maintenance, troubleshooting, installation, and repair of CNC machine tools.

The ideal candidate will have multiple years of hands-on experience servicing CNC mills, lathes, and machining centers. Experience with manufacturers such as Okuma, Haas, DMG MORI, Mazak, Fanuc, or similar equipment is highly desirable.

We are looking for a technician who can walk into a customer’s facility, diagnose a machine problem, determine the root cause, and make the necessary repairs with minimal supervision.

Candidates with extensive experience servicing CNC mills and/or lathes will be considered even if they have not worked on every machine brand listed above.

Key Responsibilities

• Travel to customer facilities to perform CNC machine service, troubleshooting, maintenance, installation, and repair.
• Diagnose and repair mechanical, electrical, hydraulic, pneumatic, and control-related issues on CNC machine tools.
• Perform preventative maintenance, inspections, machine alignments, and machine condition assessments.
• Troubleshoot CNC controls, drives, motors, encoders, servos, sensors, limit switches, and related components.
• Diagnose spindle, axis, lubrication, coolant, hydraulic, pneumatic, and tool-change problems.
• Perform machine installations, startups, commissioning, and decommissioning as required.
• Troubleshoot machine alarms and determine whether issues are mechanical, electrical, controls, programming, or operator-related.
• Read and interpret electrical schematics, mechanical drawings, hydraulic/pneumatic diagrams, and machine documentation.
• Use electrical and mechanical diagnostic tools to identify equipment failures.
• Communicate directly with customers to understand problems, explain repairs, and provide recommendations.
• Document service calls, repairs, parts used, machine conditions, and recommended follow-up work.
• Provide technical support and guidance to customers and internal personnel.
• Work with engineering and technical teams to resolve complex or recurring machine problems.
• Maintain a professional and safety-focused presence at customer facilities.
• Travel extensively as required for customer service calls, installations, and emergency repairs.

Required Qualifications

• Multiple years of hands-on experience maintaining and servicing CNC machine tools.
• Strong experience working with CNC mills, lathes, machining centers, or similar machine tools.
• Proven ability to troubleshoot and repair CNC equipment in a field-service or industrial environment.
• Strong mechanical and electrical troubleshooting skills.
• Ability to read and understand electrical schematics and mechanical drawings.
• Experience diagnosing machine faults involving motors, drives, servos, encoders, sensors, switches, hydraulics, pneumatics, lubrication, and coolant systems.
• Ability to work independently and manage service calls with limited supervision.
• Strong customer-service and communication skills.
• Valid driver's license and ability to travel extensively.

Preferred CNC Experience

Experience with one or more of the following is strongly preferred:

• Okuma
• Haas
• DMG MORI
• Mazak
• Fanuc
• Doosan/DN Solutions
• Makino
• Mitsubishi controls
• Siemens controls
• Fanuc controls
• Other major CNC machine tool manufacturers

Experience with both CNC mills and CNC lathes is a significant advantage.

Ideal Candidate

We are looking for an experienced CNC service professional, not simply a general maintenance technician.

The ideal candidate has spent several years working directly on machine tools and is comfortable troubleshooting a machine when the problem isn't immediately obvious. You should be able to systematically determine whether a problem originates with the mechanical system, electrical system, drive/servo system, CNC control, hydraulics, pneumatics, or another machine subsystem.

Candidates who have primarily worked on CNC mills and lathes but have limited experience with specific brands are encouraged to apply. Strong fundamentals and troubleshooting ability are more important than knowing one particular machine manufacturer's product line.

Core Skills

• CNC machine troubleshooting
• Mechanical repair
• Electrical troubleshooting
• Servo and drive systems
• CNC controls
• Spindle systems
• Axis systems
• Machine alignment
• Ball screws and linear guides
• Tool changers
• Hydraulic systems
• Pneumatic systems
• Lubrication systems
• Coolant systems
• Electrical schematics
• Preventative maintenance
• Machine installation and commissioning
• Customer service and technical communication

Travel & Work Environment

This is a field-based position requiring regular travel to customer manufacturing facilities.

The technician must be comfortable working in machine shops and industrial environments and may be required to work around operating CNC equipment, machining fluids, metal chips, electrical equipment, and other industrial hazards.

Overnight travel, extended workdays, and occasional emergency or after-hours service may be required depending on customer needs.

What We Offer

This is an excellent opportunity for an experienced CNC technician who wants to move into a professional field service role working on a variety of CNC machine tools and customer applications.

We value technicians who take ownership of problems, communicate well with customers, and have the technical ability to get machines back into production.

If you have several years of experience servicing CNC mills, lathes, or machining centers and enjoy troubleshooting equipment in the field, we want to talk with you.

You should be proficient in:

• Mechanical Troubleshooting Skills
• Electrical Troubleshooting
• Electrical Repair
• Maintenance and Repair Skills
• Equipment Installation & Wiring

Machines & technologies you'll use:

• Variable Frequency Drives (VFD)
• Programmable Logic Controller (PLC) (Fanuc, Siemens)
• Servo Motors
