CNC-Integrated Robotic Deburring & Machine Tending with Comau Racer-7

Automating Machining Processes for Higher Productivity

Comau’s Racer-7-1.4 robot operates in perfect synergy with a SINUMERIK 840D sl CNC system to automate both machine tending and deburring tasks.

The solution boosts productivity, ensures precise part handling, and reduces overall cycle time — thanks to a streamlined, hybrid configuration that eliminates the need for a separate robot controller.

CNC integration via SINUMERIK Run MyRobot / Direct Control
Single control unit—no external robot controller required
G-code programming for both machining and robotic motion

Hybrid Robot-CNC System in Action

Watch how Comau’s Racer-7-1.4 robot enhances efficiency at FENIX by loading/unloading parts and performing precision deburring between grinding cycles.

Controlled entirely through the SINUMERIK CNC system, the robot improves workflow, reduces idle time, and maximizes machine utilization in the metal grinding process

Case Study: Comau Racer + Siemens CNC for FENIX Tangential Grinders

FENIX, a specialist in tangential surface grinders, integrated Comau’s Racer-7-1.4 robot directly into its grinding process using Siemens SINUMERIK 840D sl. The robot handles both part loading and intermediate deburring without requiring operator intervention or dedicated robot controls.

What makes this system stand out?

The robot is equipped with a dual end-effector: one gripper and one spindle, to seamlessly switch between part handling and surface finishing.
It is programmed directly within the CNC interface, using standard G-code.
By managing both tasks from a single platform, the system enables fast changeovers, improved repeatability, and superior cycle time performance.

This hybrid automation approach reflects Comau’s commitment to flexible, efficient, and intelligent robotics for advanced manufacturing.

How the CNC-Robot Integration Works

The Comau robot is programmed and operated via the SINUMERIK 840D sl, leveraging Siemens’ Run MyRobot / Direct Control functionality. This eliminates the need for a separate robot controller, reducing hardware costs and complexity.

Robot and machine tool programs are managed on the same control system, ensuring real-time coordination and simplified synchronization—ideal for tasks like intermediate deburring between grinding passes.

Thanks to Comau’s Racer-7-1.4, known for its speed and agility, the robot performs reliable handling and deburring even in constrained spaces. Its 6-axis flexibility makes it adaptable to changing part geometries and production demands.
