Centerless Grinding Wheels

CNC grinding wheels are mainly used for precision grinding of round cutting tools, such as end mills, drills, reamers, routers, taps, and etc. These cutting tools are mainly made of tungsten carbide and high speed steel, which are used on specialized tool grinding machines for fluting, gashing and clear edge, OD grinding relief angle grinding, obtaining CNC round cutting tools with high speed and high efficiency.

CNC grinding wheels are mainly diamond wheels and CBN wheels. The bonding agent mainly include metal bond, resin bond, and resin-metal hybrid bond.

CNC Grinding Wheels Process Round Drill

Cut-off Rod

The raw materials for CNC tools are all round rods structure, and the initial process requires cutting the round rods into the required length.

Superabrasive cut off wheel is the main tool. The resin bond superabrasive cut off wheel is mainly used. Diamond cut off wheel can be used for cutting tungsten carbide bars, while CBN cut off wheel can be used for high speed steel. This kind of cutting requires high requirements for superabrasive cut off wheel, not only for long life, but also for high sharpness.

Flute Grinding Wheels

The flute grinding process is the most important part of CNC round cutting tools, with a focus on having the high stock removal rate and long life.

Therefore, it requires high for superabrasive grinding wheels which whether it is diamond grinding wheel for tungsten carbide or CBN grinding wheel for high speed steel. In the early days, it was mainly metal or resin bond grinding wheel, and now the resin-metal hybrid bond grinding wheel is the mainstream. Hybrid bond grinding wheel has the high sharpness of resin bond superabrasive grinding wheel, while also has the long life of metal superabrasive grinding wheel. So it can not only be suitable for high speed and high strength working conditions, but also has good stock removal rate and long life.

Gash Grinding

CNC round cutting tools such as the end of milling cutters, require the end of gashing to ensure that they are working and debris can be discharged normally. The stock removal rate is still big, so the superabrasive grinding wheel should have high cutting speed and high stock removal at the second relief. The tools to be ground out have the features of excellent surface finish and the best profile consistency.

OD grinding

Perform OD grinding for CNC round cutting tools to ensure good cylindricity. And share the same grinding wheel with flute grinding.

Clearance grinding

Clearance grinding is a key process in the manufacturing process of round drill tools. It ensures the free cutting ability of the cutter and reduces the feed force of drilling and milling.The superabrasive grinding wheels(diamond and CBN wheel) used for clearance grinding must maintain their shapes, while maintaining the best surface finish and accurately removing materials to achieve appropriate tool geometry for efficient and effective relief angle grinding.

Precautions for Operation of CNC Grinding Machine

Power on inspection: Before operating the CNC tool grinder, first perform the power on inspection. Check if all parts are ok, such as the electrical control system, hydraulic system, and grinding wheel dressing system.

Tool installation: Install the tool to be ground on the shaft, pay attention to the correct direction and position of the tool.
Adjusting the CNC grinding wheels: Adjust the geometric shape and size of the grinding wheel based on the shape and size of the cutting tool. It is very important. If the geometric shape and size of the grinding wheel are incorrect, it may cause to inaccurate tool grinding and even damage to the tool.

Set grinding parameters: Based on the material of the tool and grinding requirements, set grinding parameters such as grinding speed, feed rate, grinding wheel speed, etc.
Start grinding: Press the start button to start grinding. During the grinding process, it is important to observe the grinding condition of the cutting tools. If there are any abnormalities, stop the grinding immediately and check the causes.
Overgrinding: After grinding is completed, turn off the power, remove the tool, and clean the machine tool.
