CNC Machine Preventive Maintenance
Southern California Manufacturing Facilities
A crashed spindle, a lost program, or a seized axis on a $300,000 CNC machining center can shut down production for days and cost far more than a full year of preventive maintenance. Direct Source provides scheduled PM programs for CNC machining centers, lathes, and manufacturing equipment throughout Southern California — covering electrical systems, servo and spindle drives, controls and program backup, and mechanical systems. We also wire CNC machines and production equipment for OEE monitoring programs.

OEE Machine Wiring
Electrical wiring, sensor installation, and controls integration to connect your CNC machines to OEE monitoring platforms — cycle counting, uptime, fault data, and production reporting. We wire the machines, you get the data.
PM Reports & Records
Every PM visit produces a written report — work performed, findings, measurements, and recommendations. Your machine records stay current and your maintenance team has documented history for every machine in the shop.
Priority Emergency Response
PM contract clients get priority scheduling for emergency calls. When a machine goes down outside of a PM visit, you move to the front of the line — because we already know your equipment.
Machine Brands We Service
We provide PM and electrical/controls services for CNC machines from all major manufacturers — at the electrical, drive, and controls level.
Don't see your brand? Call us — we service all makes and models.
OEE Machine Wiring
Connecting Your Machines to OEE Monitoring
OEE (Overall Equipment Effectiveness) monitoring gives manufacturers real-time visibility into machine uptime, cycle times, and production losses — but it requires every machine to be correctly wired and connected to your monitoring platform.
Direct Source handles the complete electrical scope for OEE projects — sensor installation, panel wiring, conduit runs, controls integration, and commissioning — for any number of machines across your facility.
What Clients Say
Trusted by City of Industry & Los Angeles County Manufacturers
“We were experiencing electrical and PLC problems at our manufacturing plant and needed help ASAP. Direct Source came in the same day, gave us a very fair estimate, found the problem, and fixed it. We got back up and running with little downtime. These guys know what they're doing.”
“We had an unexpected production issue at our facility in City of Industry and Direct Source responded quickly. Their industrial electrician team diagnosed the problem fast and got us back up and running the same day. Professional and dependable.”
“They were professional and prompt, diagnosed the issue quickly, and fixed it at no charge since it was an easy fix. That type of customer service goes a long way in showing how they operate. They will be our FIRST call for the next electrical need.”
Why Direct Source
Why Southern California Shops Choose Direct Source for CNC PM
One Contractor — Electrical, Controls, and MechanicalMost CNC PM providers cover mechanical only. Direct Source covers all three disciplines — electrical, controls (including program backup), and mechanical — under one PM contract. One call, one schedule, one report.
Program Backup on Every VisitWe back up your CNC programs and parameters on every PM visit — not just when something breaks. If a controller fails, you're not starting from scratch.
OEE Wiring CapabilityIf you're implementing an OEE monitoring program, we wire the machines — sensor installation, panel wiring, controls integration, and commissioning. PM and OEE wiring from the same contractor.
Priority Emergency ResponsePM contract clients move to the front of the emergency queue. We already know your machines — response is faster and diagnosis is quicker because we have your maintenance history.
The Real Cost of Skipping PM
What Unplanned Downtime Actually Costs
One avoided failure typically covers multiple years of PM program cost. PM is not a cost — it's downtime insurance.

CNC Machine PM — Common Questions
What does a CNC machine preventive maintenance program include?
A Direct Source CNC PM program covers electrical (panel inspection, servo drive and spindle drive checks, power quality), controls (parameter backup, alarm history review, axis calibration checks), and mechanical (lubrication, way and guideway inspection, coolant system service, tool changer mechanical) — on a schedule matched to your machine utilization and manufacturer recommendations.
How often should CNC machines receive preventive maintenance?
Most CNC machine manufacturers recommend PM every 250–500 operating hours, which translates to monthly or quarterly visits for single-shift operations and monthly visits for multi-shift shops. Direct Source builds your PM schedule around your actual machine utilization and manufacturer specifications.
Can you wire CNC machines for OEE monitoring?
Yes. Direct Source provides electrical wiring, sensor installation, and controls integration for OEE monitoring systems on CNC machines — cycle counting, uptime tracking, fault data capture, and production reporting. We handle the complete electrical scope from sensor to platform connection for any number of machines.
What CNC machine brands do you service?
Direct Source provides PM and electrical/controls services for CNC machines from all major manufacturers — Fanuc, Siemens, Haas, Mazak, Okuma, Mitsubishi, Makino, DMG Mori, Doosan, and others. We work at the electrical, drive, and controls level across all major platforms.
Do you provide CNC PM throughout Southern California?
Yes. Direct Source provides CNC machine preventive maintenance for manufacturing facilities throughout Southern California — Los Angeles, Orange, Riverside, San Bernardino, Ventura, Kern, and San Diego counties. Call (562) 396-9924.
