Development Trend of CNC Tool Grinding Processing
As the network application of CNC machine tools becomes more and more widespread, the high reliability of CNC technology has become the goal pursued by manufacturers. In order to meet the needs of long-term unmanned operation, CNC systems and CNC devices must have high reliability. As we all know, the grinding of high-precision tools is increasingly becoming a widespread demand in the market, which also puts forward new requirements for the high-speed performance of grinders and the stable grinding performance of diamond and CBN grinding tools.
How to ensure tool quality while improving the stable and efficient grinding of carbide tools? This places higher and higher requirements on the rigidity and grinding performance of the grinding wheel. Moresuperhard has always been committed to the development and manufacture of efficient and stable grinding wheels. Provide customers with comprehensive grinding solutions.
1.Applications of resin cnc grinding wheel
Resin bonded diamond/CBN grinding wheels are used for grooving, relief grinding, peripheral and end tooth processing and grinding of CNC tools such as solid carbide and high-speed steel drill bits, milling cutters and reamers.
2.Characteristic of Resin bond cnc grinding wheel
*Suitable for high-efficiency grinding processing with rapid feed
*Good wear resistance and shape retention
*It has good self-sharpening properties, generates less grinding heat, reduces burns on the workpiece, and meets the high-precision requirements of the tool.
*No clogging, easy to trim, extend the trimming cycle and reduce processing costs.
*The grinding workpiece has consistent edge quality and high smoothness, which ensures stable quality when processing downstream products.
1.Dressing wheel for CNC grinding wheel
Dressing wheel for resin cnc grinding wheel:Green silicon carbide dressing wheel or aluminum oxide dressing wheel
Dressing Grain size: 80-120 mesh, also depends on the grinding wheel size
Dressing wheel Hardness:E, G, H, J/K
Grinding wheel linear speed: 2-6m/s
Dressing wheel linear speed: 8-25m/s
Swing speed: 200-1000mm/min
Rough dressing: 0.02-0.08mm/time
Fine dressing: 0.005-0.02mm/time
Use coolant whenever possible When dressing fine-grained grinding wheels, the feed rate should be reduced (In addition, increasing the grinding wheel speed or reducing the feed speed can improve the surface finish)
2.Dressing sticks for CNC grinding wheel
Use soft and fine-grained oilstone for sharpening, and grind tightly against the grinding wheel until the diamond on the surface of the grinding wheel is exposed.
Abrasives of oilstone:Alumina
Recommended particle size: 240-320
Recommended hardness G or H
Precautions for using dressing olistone:Coolant soaked oil stone strips; During sharpening, the rotation direction of the diamond grinding wheel should be consistent with the grinding rotation direction;Dressing should be done after dressing or any time the wheel becomes clogged and creates more load.
Moresuperhard always focuses on R&D and innovation. Moresuperhard is committed to providing better quality products to customers in the CNC tool industry, helping customers improve grinding efficiency and reduce overall costs by using Moresuperhard's CNC grinding wheels.
In modern manufacturing, tungsten steel (hard alloy) is widely used due to its high hardness and wear resistance. However, the requirements for tools when processing tungsten steel are extremely high, especially the selection of suitable grinding wheels is crucial in the grinding process. This article will share the case of us providing customers with high-quality grinding wheels and successfully solving their processing problems.
SG grinding wheels are suitable for grinding carburized steel. Their high hardness and self-sharpening properties enable them to effectively grind the high hardness surface of carburized steel, while low heat generation and good heat dissipation reduce thermal damage during the grinding process. In addition, the wear resistance of SG grinding wheels also helps to extend the service life of the grinding wheels and reduce grinding costs.
