ID/OD Grinding Machines

we understand how important accuracy and reliability are when working with complex metal parts. That’s why our CNC Grinders and ID/OD Grinders are designed to handle the toughest jobs with ease from shaping crankshafts and camshafts to working on valves, bearings, and transmission shafts.  

Why Choose Our Grinders? 

Built for All Kinds of Jobs 
Whether you’re working with hardened steel or even ceramics, our grinders can handle it. They’re a goto solution for industries like automotive, aerospace, medical, and more. You can rely on them for everything from part repair to finishing surfaces with different textures. 

Extreme Accuracy, Every Time 
Some parts need to be just right down to the tiniest measurement. Our ID/OD grinders can consistently hit tight tolerances that are hard to achieve with other machines. If you’re in a field where precision is non-negotiable, these machines have your back. 

Handles Complex Shapes  
Have a tricky part with grooves, tapers, or hollow areas? No problem. Our grinders are built to handle complex internal and external shapes with ease, thanks to specially designed grinding wheels that shape parts exactly the way you need.

 
Faster, Smarter, More Efficient 
Compared to traditional machining, our grinders remove material quickly without wasting time or resources. That means faster production, lower costs, and a smoother process from start to finish.

Our Machines 
We offer two powerful models that suit different needs: 

TIG-150 – CNC Internal Grinding Machine 
TOG-2550 – Precision CNC Cylindrical Grinder 

What They Offer: 

• Consistent Accuracy & Stability – Built to deliver repeatable results you can count on. 
• Built-In Cooling System – Includes oil mist and magnetic filters to keep the machine running at its best. 
• Fully Enclosed Design – Keeps operations clean, safe, and professional. 
• Automated Grinding Cycle – The machine takes care of grinding and wheel dressing automatically. 
• Precision Ball Screws – Pre-tensioned ball screws on both X and Z axes help with pinpoint positioning. 
• High-Frequency Spindles – Both machines use a constant torque electric spindle, perfect for precision work. 
• Smart Grinding Speed – With constant linear velocity (Vc), grinding stays consistent and efficient. 
• Hand-Scraped Guide Ways – On the TOG-2550, the traditional “V” and flat guide ways are hand-finished for better control. 
• Easy Handling – Electronic hand wheels for smooth, manual positioning powered by AC servo motors. 
• Special Bearings – TOG-2550 also features hydrostatic bearings, ideal for absorbing shocks during high-speed work. 
• Strong Foundation – Both machines are built on a solid Meehanite cast iron base, heat-treated for long-term durability. 
• Simple Programming – Featuring Mars conversational programming, you don’t need to be a coding expert to run them. 

Where These Grinders Fit Best
Our machines are already making a difference in: 

• Aerospace workshops 
•  Automotive manufacturing 
• Medical device production 
• Mold & die making 
• Shipbuilding yards 
• Bike and appliance factories 
• And anywhere micromachining is needed

If you're looking for grinders that are powerful, precise, and easy to use — without all the complicated setup — our CNC ID/OD grinders are exactly what your shop needs. Built with care, designed for real-life use, and backed by TOP-ONE's engineering.
