Frequently Asked Questions
Absolutely! Minnuo has an experienced pre-sales technical team. As long as you provide the part drawings, whether it's for internal hole machining with an internal cylindrical grinding machine or a customized model with combined functions, we can recommend a single machine within 10 minutes. For solutions involving multiple machines, a complete proposal will be provided within 5 working days.
Yes. I can customize a CNC internal cylindrical grinding machine based on workpiece size, accuracy requirements, automation level, and more—including spindle type, grinding wheel configuration, automatic loading/unloading system, and cooling system—so it fully matches my on-site production needs.
We are equipped with multiple high-end international machining centers, ensuring that all key components of the internal cylindrical grinding machine have high precision and consistency. Each machine is fully tested before delivery and comes with a detailed quality inspection report.
For standard models, we have inventory available for fast delivery. For customized internal cylindrical grinding machines, the delivery time is generally 30–45 working days. We will confirm the exact timeline based on the complexity of the order.
Yes. Whether it’s the control system, machine bed design, grinding range, or sheet metal guarding, I can fully customize the internal cylindrical grinding machine based on my specific needs. You also offer combined solutions like internal and external cylindrical grinding machines in a single setup.
An internal bore grinding machine is mainly used for machining internal holes of parts such as sleeves, gear bores, bearing inner rings, and hydraulic components. You can use it to achieve high-precision grinding of inner bores, stepped holes, tapered holes, and more. It is widely applied in industries like automotive, hydraulics, and mold manufacturing.
Our high precision internal grinding machine can consistently achieve machining accuracy within 2μm, and some high-end models can reach below 1μm in a temperature-controlled workshop. If I have high requirements for roundness or coaxiality, I can also choose optional in-process measuring systems and active dressing units.
Not at all. You only need to regularly check the lubrication oil, grinding wheel wear, spindle operation status, and whether the cooling system is functioning properly. Our internal cylindrical grinding machine is designed with a compact structure and easy maintenance in mind. We also provide maintenance manuals and training services to help you complete daily upkeep with ease.
