Technical Evaluation of the Leblond-Makino FNC 125 LA-24
CNC Vertical Machining Center (3-Axis)
1. Technical Evaluation Overview
The Leblond-Makino FNC 125 LA-24 is a 3-axis CNC vertical machining center configured for general-purpose milling operations. The machine is equipped with a Fanuc OMC CNC control, indicating an early-generation CNC platform with basic contouring and feed control capabilities.
The work envelope includes a table size of 94.5″ × 27.5″, with linear travels of X 80″, Y 27.5″, and Z 27.5″. A minimum spindle nose-to-table distance of 9-3/4″ is specified, which defines lower tool clearance limits.
Spindle specifications list a CAT 50 taper, a speed range of 0–3,500 rpm, and a 15 HP motor rated at 30 minutes, reflecting a torque-oriented configuration suitable for moderate material removal rather than high-speed machining.
Feed capabilities include rapid traverses of 300 IPM and cutting feedrates from 0 to 150 IPM. No information is provided regarding tool changer configuration, axis drive type, machine weight, or accuracy specifications.
2. What to Check Before Buying
Given the limited specification detail and the age implied by the Fanuc OMC control, inspection should focus on core mechanical and control integrity.
Mechanically, the linear ways and ballscrews should be checked for wear, backlash, and smoothness of travel, particularly along the long X-axis. The CAT 50 spindle should be evaluated for bearing noise, runout, and thermal behavior across the full speed range.
From a control standpoint, the Fanuc OMC system should be powered and tested for memory retention, alarm history, and axis response. Availability of parameter backups, manuals, and replacement components should be confirmed, as support options may be limited compared to newer controls.
Electrical cabinets, servo drives, and safety circuits should be inspected for aging components, modifications, or undocumented repairs.
3. Typical Industrial Applications
Based strictly on the stated travels, spindle configuration, and feed capabilities, this machine is suited for general vertical milling, drilling, and basic contouring of medium-sized prismatic parts. Typical applications include fixtures, base plates, housings, and general industrial components that do not require high spindle speeds or advanced multi-axis interpolation.
4. Common Risks in Used Machines
Common risks with used machines of this category include way and ballscrew wear, reduced positioning accuracy, and obsolescence of CNC control components. Electrical issues related to aging power supplies, encoders, or servo amplifiers are also typical concerns. Limited documentation or missing parameters can significantly affect explainability and future troubleshooting.
5. Maintenance and Service Considerations
Maintenance requirements depend on actual usage and service history, which are not provided. Regular attention should be given to way lubrication, spindle condition, and electrical cabinet cooling. Long-term service planning should consider the availability of Fanuc OMC parts, documentation, and qualified service support.
Given the stated floor space requirement of approximately 18′ × 20′, adequate access should be ensured for maintenance and potential component replacement.
Final Note:
While the machine’s travels, spindle, and feed capabilities are clearly stated, critical details—such as tool changer configuration, axis accuracy, machine weight, and maintenance history—are important. These elements should be verified through inspection, testing, and documentation review before forming final technical conclusions.
