Let’s set the stage. You are standing on the production floor at Mitsubishi Power Americas. The environment is loud, active, and dominated by a steam turbine rotor roughly the size of a small house. It is massive, high-value, and imposing.
For this colossal machine to operate without failing, the surface finish on critical components like rotor journals, blade roots, and valve stems must be impeccably smooth. We are talking about mirror-like perfection.
If there is a patch of roughness even the size of a dust speck (high Ra or Rz numbers), you get friction. You get heat build-up. You get a multimillion-dollar asset compromising its own efficiency.
The Struggle: Why Moving Heavy Metal is Inefficient
Here is the logistical hurdle that typically frustrates production managers. Historically, if you wanted to verify that surface to laboratory standards, you faced two inefficient options.
Option one: Transport this multi-ton steel giant to a dedicated metrology room. That involves cranes, specialized rigging crews, and a schedule delay that hurts the bottom line.
Option two: Cut a sample from the part. Destroying the component you just manufactured to verify its quality is, in our view, an absurd approach.
Mitsubishi Power adheres to strict international protocols (ISO 4287, DIN), so visual estimation is not an option. They were caught between rigid compliance requirements and the physical reality of their heavy machinery.
The Solution: Lab-Grade Data in a Handheld Format
We stepped in with a better alternative. We assessed the situation and supplied the QualiSurf™ I Portable Surface Roughness Tester.
We will be direct. This compact device outperforms many stationary lab machines in this specific context. It fits in the palm of a hand yet delivers the rigorous precision auditors demand. We knew Mitsubishi required equipment that could survive the manufacturing floor while providing valid data.
The Workflow Shift
Visualize the change on the floor. Instead of halting the line to transport a shaft, a technician retrieves the QualiSurf™ I from a pocket. They step onto a platform, extend the device into the deep, awkward curve of a turbine groove, a geometry that often baffles standard testers, and position the diamond-tipped sensor against the metal.
There is no commotion. No cables tangled across the floor. The sensor detects every microscopic peak and valley, those granular imperfections that ruin aerodynamics, and immediately displays the result.
The crisp OLED screen presents the data instantly. It handles outer cylinders, cones, and angled grooves efficiently. The technician notes the numbers, approves the part, and production continues.
The Outcome: Precision Without the Overhead
The result? Absolute operational efficiency. By discarding the "transport to the lab" methodology, Mitsubishi Power Americas recovered significant capital and time.
- Eliminated Transport Risks: No more cranes. No more waiting. The metrology lab effectively moves to the component.
- Immediate Decisions: We value tools that provide data instantly. Operators identify deviations while the component is still on the machine, preventing expensive rework later.
- Cost-Efficient Scaling: Because the QualiSurf™ I offers high specifications at a reasonable price point, they could equip multiple engineers with individual units.
We firmly believe you do not require a room-sized machine to measure a room-sized part. You simply need a tool capable of doing the work. This solution delivers exactly that.
