With the continuous increase in tungsten carbide raw material prices, the cost of CNC milling cutters has remained consistently high. As a result, more and more machining companies are investing in automatic tool grinding machines to extend tool life and reduce overall tooling costs.Under these market conditions, the Meiwha Automatic Grinding Machine has gained strong recognition from customers.
This article introduces the Meiwha Automatic Grinding Machine and its key advantages in modern CNC workshops.
Applicable Tools and Flute Configurations
The Meiwha Automatic Grinding Machine is designed for tools with diameters ranging from 3 mm to 20 mm, covering the majority of commonly used cutting tools in CNC machining(The machine is suitable for regrinding: Flat end mills, Ball nose end mills, Corner radius cutters, Chamfer tools, Drill bits). It supports 2-, 3-, 4-, 5- and 6-flute tools, making it highly versatile.
Thanks to its wide compatibility, this grinding machine eliminates the need to purchase multiple machines for different cutter types, making it a practical and cost-effective solution for machining workshops.
Stable Grinding Quality and High Efficiency
One of the most frequently asked questions from customers concerns grinding efficiency. Depending on tool diameter, the typical grinding time is 1–2 minutes per tool, allowing efficient daily operation.
The machine is equipped with a high-speed grinding wheel capable of reaching up to 5,000 rpm, ensuring stable material removal and consistent cutting-edge quality. With a rated total power of 4 kW, the system maintains reliable performance even during continuous operation.
The standard grinding wheel size is 125 mm × 10 mm × 32 mm, and users can select either CBN or SDC grinding wheels according to tool material and application requirements. For example, when regrinding a 6 mm diameter end mill, a single grinding wheel can typically be used for 2,000–2,500 cycles, offering excellent cost efficiency.
Self-Developed Control System with Simple Operation
The grinding machine is equipped with a self-developed control system, designed and maintained by Meiwha’s own engineering team. Continuous updates and optimisation ensure the system remains adaptable to real machining requirements.
Combined with high-precision servo motors and a touchscreen interface, the machine also features automatic tool setting and automatic calibration functions. These functions significantly reduce manual measurement and adjustment time, making operation simpler and more consistent.Even operators with limited experience can become proficient quickly.
Four-Axis Grinding with Automatic Oil Spraying
The machine adopts four-axis simultaneous control, enabling complex grinding paths that improve cutting-edge accuracy and surface finish. An integrated automatic oil spraying system reduces heat and friction during grinding, helping to extend tool life and improve cutting stability after regrinding.
No Tool Length Limitation and Improved Working Environment
Unlike conventional grinding machines, this model has no limitation on tool length, allowing tools of any length to be reground without compromising stability or accuracy.
In addition, the machine is equipped with a built-in dust extraction system, improving workplace cleanliness and protecting maintenance personnel. This makes it particularly suitable for production environments with high environmental and safety requirements.
A high-performance CNC automatic grinding machine is not only a tool reconditioning device, but also an important production asset for improving machining consistency and cost control. With wide tool compatibility, advanced automation, and user-friendly operation, the Meiwha Automatic Grinding Machine provides a reliable and efficient solution for modern CNC tool regrinding.
If you are looking to extend tool life, reduce operating costs, and achieve stable, efficient tool regrinding in your CNC workshop, please contact us to discuss whether this automatic grinding machine is suitable for your specific application.
