Measure the Machine Before You Guess
Machine tool calibration compares commanded motion with measured machine performance. Founders CNC uses ballbar, laser, test bars, indicators, and machine-specific alignment equipment to identify geometry, positioning, servo, feedback, and mechanical problems.
Because we also repair machine tools, the report does not have to become a handoff to another contractor. We can define and complete approved corrective work, then retest the machine. We may evaluate some control and drive problems through remote support when safe access is available.
Calibration and Verification Capabilities
- Renishaw ballbar testing and performance trending
- Laser measurement and axis-positioning evaluation
- Machine geometry checks using test bars and indicators
- Spindle, axis, and automatic tool-changer alignment
- Five-axis and rotary-axis troubleshooting
- Mill-turn alignment and performance checks
- HEIDENHAIN encoder and scale diagnosis
- Mechanical, electrical, drive, and control correction based on findings
How the Work Proceeds
Define the production requirement
We start with the machine, tolerances, symptoms, recent events, and the reason for measurement—such as a crash, preventive maintenance, process qualification, acceptance, or recurring part error.
Select the appropriate measurements
A ballbar test, laser measurement, spindle check, and five-axis kinematic evaluation answer different questions. We select the methods that fit the machine and objective.
Measure and document
Our technician runs the agreed tests and documents the machine’s condition. The results establish a baseline and point toward likely causes.
Correct and retest
If the work is approved, we adjust or repair the systems responsible for the error and repeat the relevant measurements to verify the result.
What a Ballbar Test Shows
A Renishaw ballbar measures small changes in radius as a CNC machine follows a programmed circular path. Analysis can reveal positioning and servo-performance characteristics and report circularity or circular deviation. Renishaw supports reporting to standards including ISO 230-4 and ANSI/ASME B5.54.
When to Measure a Machine
- After a crash or significant repair
- Before a demanding or turnkey production run
- When parts drift out of tolerance
- During machine acceptance or relocation
- At scheduled preventive-maintenance intervals
- When building a performance history for critical equipment
Frequently Asked Questions
Do you calibrate at our facility?
Yes. Machine measurement is normally performed onsite so the machine is evaluated on its operating foundation and in its production environment.
Does calibration automatically include adjustment or repair?
The approved scope defines the work. Measurement may be performed as a stand-alone service, or we can propose corrective work based on the findings and retest after approval.
Can you work on five-axis and mill-turn machines?
Yes. We troubleshoot and measure multi-axis and mill-turn equipment. The exact method and acceptance criteria are selected for the machine configuration and customer requirement.
Will I receive a report?
After calibration, Founders CNC provides documentation tailored to the machine and work performed. When applicable and available, the package may include Renishaw or HEIDENHAIN reports.
What warranty applies to corrective work?
Founders CNC provides a 30-day labor warranty. New and refurbished parts carry the applicable manufacturer or supplier warranty.
