REWARD: Immediate Production Restoration and Shop-Floor Control.
We are issuing an all-points bulletin for a very specific business in the USA. Right now, there is a shop out there caught in a Production Hemorrhage. They just signed a massive contract with an impossible start date, or their legacy grinder finally gave up on them.
They know they need elite precision, but the industry is telling them to wait in line for a 12-month lead-time. Out of sheer desperation, they are scouring eBay and used machinery auctions for a $50k dinosaur that comes with no warranty, no history, and no support.
If this sounds like you, stop searching. We found you. And more importantly, we have exactly what you are looking for.
Sitting on our showroom floor in Atlanta, Georgia, is a brand-new, premium European Robbi IGR 250 Internal Grinder.
It is prepped, tested, and ready to ship.
We are looking to bypass the global supply chain crisis and put this heavy iron exactly where it belongs: on your floor, making chips by next week.
The Interrogation Room: Answering Your High-Stakes ID Grinding Questions
Before you back a truck up to our loading dock, we know you have to justify the investment.
Whether you are fighting with the C-Suite to release a PO or you are the Head Maintenance Tech tired of operator abuse, here is the technical logic you need to move things along.
What is an ID (Internal Diameter) Grinding Machine and How Does it Work?
Internal Diameter (ID) grinding—also known as bore or inside grinding—is a highly specialized machining process designed to finish the inner surfaces of cylindrical or tapered holes to absolute strict tolerances. Unlike external grinding, an ID grinder utilizes a high-RPM wheelhead spindle engineered to rigid standards to reach inside precise cavities while completely avoiding wheel deflection.
What is the difference between a manual ID grinder and a CNC/PLC machine?
If you are evaluating a traditional manual ID grinder versus a full CNC machine, the Robbi Omicron series eliminates the compromise. Full CNC internal grinders are unmatched for high-volume, continuous production, but programming them for a single custom piece or a small batch can create a massive bottleneck in a job shop.
Our semi-automatic (PLC) solutions bridge this gap by marrying manual simplicity with CNC precision. With intuitive controls, operators can set up and finish a custom bore in a fraction of the time it takes to code a conventional CNC cycle.
What are the benefits of PLC-controlled grinding machines?
The Robbi IGR 250 is equipped with a Siemens TP 700 touchscreen control panel. This conversational interface is the ultimate cheat code for your operators.
- It supports both plunge and pass modes across up to 12 different diameters in a single cycle.
- It allows an operator to program complex working cycles through guided, icon-based menus without needing any prior ISO programming knowledge.
- It supports automatic grinding wheel dressing with dimensional compensation, reducing operator error and ensuring accurate geometric results.
What applications require precision internal bore grinding?
Robbi internal grinders are uniquely qualified for industries requiring absolute concentricity, straightness, and micro-inch surface finishes.
- Aerospace & Defense: Ideal for processing landing gear components, specialized actuator sleeves, and aerospace valve housings.
- Tool & Die Shops: Perfect for custom bushings, draw dies, master gages, and jig components.
- Automotive & Motorsports: Extensively used for reconditioning or manufacturing custom gears, collets, and heavy-duty transmission components.
- Repair & Maintenance: The universal spindle nose readily accommodates a traditional four-jaw chuck or faceplate, making it the premier choice for fast changeovers on one-off repair jobs.

Global Iron, Local Backbone
Upgrading an obsolete machine like the classic Heald 273A with a used auction-block special is a gamble. When you buy used, you buy someone else's problem.
At Ecotech Machine Tool, we are seasoned industry veterans with machinist blood. We aren't guys in suits; we know exactly what it takes to keep a floor running.
We hunted down the best Italian engineering from the Robbi Group, but we support it right here at home. When you take delivery of this IGR 250, you are getting comprehensive support, operator training, rapid parts delivery, and technical repairs from our Atlanta team.
