Renishaw RMP400S: A New Era of On-Machine Inspection Begins

Manufacturing is entering a new phase where precision, automation, and digital quality control are no longer optional—they are essential. As CNC machining becomes more advanced, manufacturers are looking for faster ways to inspect parts without removing them from the machine.

Renishaw is addressing this challenge with the introduction of the RMP400S, an innovative all-in-one machine tool probe designed to combine touch-trigger probing, continuous scanning, and surface finish verification in a single solution.

Scheduled for global launch in Autumn 2026, the RMP400S represents one of Renishaw’s most significant metrology innovations in recent years. The company will showcase the new probe at major international manufacturing exhibitions, including IMTS 2026 in Chicago, AMB 2026 in Stuttgart, and JIMTOF 2026 in Tokyo.

For manufacturers pursuing Industry 4.0 and smart factory initiatives, the RMP400S has the potential to simplify inspection workflows while improving productivity and part quality.

What is the Renishaw RMP400S?

The Renishaw RMP400S is a next-generation machine tool probe developed for modern CNC machining centres. Unlike conventional probes that primarily perform touch-trigger measurements, the RMP400S combines multiple inspection capabilities into a single spindle-mounted device.

The probe enables manufacturers to move seamlessly between:

• Touch-trigger measurement
• Continuous scanning
• Surface finish verification

Instead of relying on multiple inspection tools or transferring parts to external measuring equipment, manufacturers can perform critical quality checks directly on the machine.

This integrated approach supports faster decision-making, reduces manual intervention, and helps maintain consistent manufacturing quality throughout production.

Why Modern Manufacturing Needs More Than Traditional Probing

Traditional touch-trigger probing has become a standard feature in CNC machining for setting work offsets and measuring finished parts. However, today’s manufacturing environment presents new challenges.

Modern components often feature:

• Complex freeform geometries
• Tight dimensional tolerances
• Multi-axis machining operations
• High-value materials
• Increased automation requirements

Manufacturers also need greater visibility into the quality of every component before it leaves the machine.

As quality expectations continue to rise across industries such as aerospace, automotive, medical, precision engineering, and semiconductor manufacturing, inspection systems must provide more information than simple dimensional measurements.

The Renishaw RMP400S has been developed to address these evolving production requirements.

Key Features of the Renishaw RMP400S

1. Three Measurement Technologies in One Probe

One of the biggest advantages of the RMP400S is its ability to perform multiple inspection tasks using a single probe.

The system combines:

• Touch-trigger probing
• Continuous scanning
• Surface finish verification

This reduces the need for multiple measuring devices and simplifies inspection processes within the CNC machine.

---

2. Built for Smart Manufacturing

Smart manufacturing relies on accurate production data collected directly from the machining process.

The RMP400S supports this approach by enabling on-machine inspection throughout the production cycle.

Instead of waiting until machining is complete, manufacturers can verify part quality during production, helping identify potential issues earlier and reducing costly rework.

---

3. Increased Productivity

Using one probe for multiple inspection functions can significantly reduce:

• Machine idle time
• Probe changes
• Manual inspection
• Secondary quality control operations

By minimizing interruptions, manufacturers can improve machine utilization and overall production efficiency.

---

4. Continuous Scanning Capability

Continuous scanning provides more detailed information than traditional point measurements.

Rather than measuring only selected locations, scanning captures a larger amount of surface data, allowing manufacturers to evaluate component geometry more comprehensively.

This capability is particularly valuable for complex 3D surfaces and precision-engineered components.

---

5. Surface Finish Verification

Surface quality plays a critical role in many high-performance applications.

The RMP400S introduces surface finish verification directly on the machine, helping manufacturers evaluate surface conditions without transferring parts to separate inspection equipment.

This additional capability supports improved process control and faster production decisions.

---

6. Easy Programming

Renishaw has designed the RMP400S to work with its established probing software ecosystem.

Manufacturers do not require advanced G-code programming expertise to configure inspection routines.

The intuitive software simplifies setup while helping operators implement inspection cycles more quickly.
