For CNC machining enterprises, as the price of tungsten carbide—the raw material for cutting tools—continues to rise, the cost of cutting tools has increased accordingly. In order to better help customers extend tool life, our company has developed a new CNC Grinding Machine.
This CNC Grinding Machine enables fast and efficient tool regrinding, helping to extend tool service life while reducing the frequency of new tool purchases, thereby supporting more controlled production cost management.
Application Range and Basic Parameters of Our CNC Grinding Machine
This CNC grinding machine is primarily designed to meet the regrinding requirements of commonly used milling and drilling tools. It supports a tool diameter range of 4 mm–20 mm and is suitable for 2-flute, 3-flute, and 4-flute tools, covering the most widely used tool specifications in machining workshops.
The machine has a rated total power of 2.5 kW and a grinding wheel speed of 2500–3000 rpm, ensuring stable grinding performance while maintaining equipment durability and operational safety. Typical grinding time per tool is 1–2 minutes, which meets the efficiency requirements of daily workshop operations.
The grinding wheel specification is 124 mm × 10 mm × 32 mm, providing a good balance between precision and durability. Taking an 8 mm diameter end mill as an example, a single grinding wheel can typically complete 800–1000 regrinding cycles, offering strong cost efficiency over long-term use. The overall machine dimensions are 685 mm × 600 mm × 685 mm, with a compact structure suitable for flexible installation in most machining workshops.
Operating Modes of the CNC Grinding Machine
The control system of this CNC grinding machine provides two operating modes: Manual Mode and Automatic Mode, to meet different regrinding requirements.
Manual Mode is mainly used to address special tool regrinding needs. In this mode, operators can perform coarse tool setting, grinding wheel adjustment, and workpiece positioning. The available functions include grinding wheel jogging, motor start and stop, tool-setting position definition, and zero return for the grinding wheel and all axes. This mode is more suitable for experienced operators who require customised adjustments.
Automatic Mode is the core highlight of this CNC grinding machine. In this mode, the entire grinding process is completed without manual intervention. During operation, the system performs linear compensation along the X and Y axes to automatically offset grinding wheel wear. In addition, tool parameters can be adjusted based on actual grinding results, ensuring consistency in tool geometry and regrinding quality. This automatic compensation mechanism significantly reduces reliance on operator experience and makes the grinding process more stable and repeatable.
Important Notes for Using the CNC Grinding Machine
After power-on, the machine automatically performs a homing sequence. If the emergency stop button is pressed during this process, the machine will not be able to complete automatic homing and must be reinitialised using the one-key reset function.
For tool clamping, different tool types have specific clamping length requirements. The clamping length for flat end mills and corner radius cutters should be ≤ 25 mm; for drills and ball nose cutters, the clamping length should be ≤ 40 mm (it is recommended to clamp above the flute); for chamfer tools, the clamping length should be ≤ 55 mm, and the use of an extension holder is recommended to ensure stable clamping.
In addition, due to differences in helix angle, core structure, and thickness among tool manufacturers, tool-setting compensation should be adjusted based on a 0° reference. For flat end mills, a +2° compensation angle results in a sharper cutting edge, while −2° improves wear resistance. For corner radius cutters with R1 and no clearance on the side cutting edge, using 0° as a reference and applying a slightly more negative angle helps achieve a smooth transition between the radius and the side cutting edge. Ball nose cutters typically use a −2° compensation angle to improve side edge continuity. Drills are recommended to use a −5° compensation angle to align the cutting faces and keep the cutting edges parallel. The exact compensation angle should be fine-tuned according to the actual helix angle; if the requirements are already met at 0°, no adjustment is necessary.
For CNC machining enterprises that prioritise stable machining quality and effective cost control, a CNC Grinding Machine is not only a tool regrinding device, but also a long-term tool management solution. Through appropriate parameter configuration, automated grinding modes, and stable compensation mechanisms, this equipment helps workshops effectively extend tool life, reduce operating costs, and maintain consistent machining quality over time.
