Calibration, done on your floor

Renishaw laser and ballbar systems, traceable data, and machines back to making parts to print — fast.

Ballbar Analysis

Under 30 minutes per test

A fast, quantitative machine health check with Renishaw QC20 — detailed error maps that pinpoint the exact error source, logged for trend monitoring over time.

Laser Calibration

Direct measurement of geometric errors — linear, angular, straightness, and squareness — with Renishaw XL-80 / CARTO. Traceable data and compensation adjustment to bring the machine back to spec.

Rotary Axis Calibration

±1 arc second

4th and 5th axis calibration with Renishaw XR20 — the most common accuracy problem on multi-axis machines, found and fixed.

Five-Axis Machine Calibration

Full-machine accuracy verification. A five-axis machine is only as accurate as its least accurate axis — we find it and hold it true.

New Machine Baseline Reports

Third-party accuracy verification before production. Protects the buyer, backs up the seller, and documents day one.

Post-Crash Machine Health Checks

After an "unscheduled event," confirm machine health in minutes — before risking another production part.

On-Site Renishaw Training New

Hands-on laser and ballbar training for your maintenance staff, so your team can diagnose and verify in-house.

Certification

Calibration reports and the certification sticker to prove it — data your QA and customers can trust.

Fixtures stay in place. MAP's calibration setup can often run without removing fixtures. On a recent 13-machine job that saved countless hours of teardown, re-setup, and prove-out — getting machines back into production fast.

Why calibrate

Machines drift. Parts tell you too late.

CNC machines lose accuracy quietly — wear, thermal drift, a bumped fixture, an "unscheduled event" nobody mentioned. By the time scrap parts show up, you're already paying for it: wasted material, blown deliveries, QA pointing at the machine while the floor points at programming.

Calibration ends the finger-pointing with data.

A Renishaw QC20 ballbar check takes under 30 minutes and produces a detailed error map that shows exactly what the machine is doing — and why. Compare that to the old circle-diamond-square test that tied up the machine and QC for hours.

The downtime math.

When times are good, "we don't have time in the schedule." When times are slow, "we don't have the money." But when the machine is down — no time, no money, and you need that machine now. Scheduled calibration turns surprise downtime into planned maintenance, on your calendar instead of your customer's deadline.

Five-axis reality.

Your machine is only as accurate as its least accurate axis — and in the field, the least accurate axis is most often a rotary. Rotary errors on 4th and 5th axes quietly explain a lot of "why won't this part come in to print." The Renishaw XR20 measures rotary positioning to ±1 arc second and finds them.

New machine? Baseline it before the first chip.

A third-party baseline accuracy report proves your investment meets the specs you paid for — and gives the OEM confidence they delivered a quality machine. Don't wait for quality issues to wonder whether the problem was there from day one.

About

About Mark

Mark Prendergast next to the MAP Machine Calibration service trailer

Mark Prendergast was 14 years old when his father showed him how to crank the handles on a Bridgeport, making keys for Boeing as a sub-subcontractor — enough money to keep a mini bike fueled. Decades later, that path ran through tracer mills, production floors, and the startup of programs like the F-22 Raptor, into the modern era of five-axis machining.

Mark founded MAP Machine Calibration in January 2025 to do the work he's most passionate about: making machine tools as accurate as they can be. Armed with Renishaw laser and ballbar systems, he provides baseline accuracy reports, diagnostics, compensation, and calibration for shops across the country — "attention to detail calibration," from the Puget Sound to wherever the work is.

The business has grown the best way a service business can: word of mouth. When shops refer MAP, it's because their machines came back to production making parts to print, fast.

It's not that I have to go to work — I get to go to work.
The Tools

Precision You Can Verify

MAP Machine Calibration runs Renishaw metrology systems — the industry standard for machine tool calibration — with every measurement traceable to national and international standards.

Laser Interferometer

Renishaw XL-80

±0.5ppm accuracy
1 nmresolution
80 maxis length

The core of MAP's calibration system — direct measurement of a machine's geometric errors: linear positioning, angle, straightness, and squareness.

  • XC-80 environmental compensator corrects for air temperature, pressure, and humidity in real time
  • Captured and analyzed in Renishaw CARTO software to international standards
  • Machine compensation tables updated on the spot
Rotary Axis Calibrator

Renishaw XR20

±1″arc second
4th & 5thaxis rotary

Rotary axes are the most common accuracy problem on 4- and 5-axis machines — and the XR20 finds it, measuring rotary positioning to ±1 arc second in any orientation.

  • Works with the XL-80 laser system
  • Wireless operation for fast setup
  • CARTO off-axis mode handles 5-axis and trunnion machines even when the calibrator can't sit on the center of rotation
Ballbar

Renishaw QC20

10–20minute test
100–600mm test radii

The fast machine health check. A wireless ballbar test produces a detailed error map showing exactly what the machine is doing and why — separating geometric, dynamic, and play-related errors so the fix targets the real problem.

  • Reportable to ISO 230-4 and ANSI B5.54
  • Every test logged so machine performance can be trended over time
  • Mark runs one on every post-calibration project
Traceable to national and international standards. Every job ends with documented data reportable to ISO 230-4ANSI B5.54

Every job ends with documented, traceable data — a calibration report your QA department and your customers can trust.

FAQ

Questions, answered

Do you travel? How far?
Yes — that's the business. MAP is based in the Puget Sound area of Washington and serves shops nationwide. Recent work has run from Seattle to California to Florida and back. If your machine needs calibration, distance isn't the problem.
What equipment do you use?
Renishaw systems: the QC20 ballbar for machine health checks and diagnostics, the XL-80 laser interferometer with CARTO software for geometric calibration, and the XR20 rotary axis calibrator for 4th and 5th axes. All measurements are traceable and documented.
How long does a calibration take?
It depends on the machine and scope. A ballbar health check takes under 30 minutes per test. Full laser calibration of a machine takes longer — request an estimate with your machine details and you'll get a realistic time and cost picture. MAP's setup can often run without removing your fixtures, which saves hours of teardown and prove-out.
Will this disrupt production?
The goal is the opposite. Calibration is scheduled around your production, and the priority is always getting the machine back to making parts within tolerance as quickly as possible. Time is money.
My parts are out of tolerance. Is it the machine or the program?
That's exactly the question calibration answers. QA blames the machine, the floor blames the program — ballbar and laser data settle it with an error map instead of an argument, so you fix the true source of the issue.
We just bought a new machine. Why calibrate it?
A third-party baseline accuracy report confirms the machine meets the accuracy and geometry specs you paid for — before you ever make a chip. It protects you, gives the OEM confidence in what they delivered, and documents day-one condition so you never have to wonder whether a problem was there from the start.
We crashed a machine. Now what?
Don't risk a production part hoping it's fine. A quick ballbar health check — under 30 minutes — tells you whether the crash affected machine accuracy, and laser calibration can correct it if it did.
Can you train our people?
Yes. MAP offers hands-on, in-house Renishaw laser and ballbar training so your maintenance staff can diagnose issues and verify machine health themselves.
What do we get when you're done?
A calibration report documenting your machine's measured accuracy, the certification sticker on the machine, and data your QA and customers can trust.
How do I get started?
Send an estimate request with your machine's make, model, and what it's doing (or not doing). You'll get a response with a realistic scope and price, then pick a time on the schedule.
