As you can see, the Rockwell Hardness Chart is a very useful tool for gauging the hardness of your tools. It's also an important factor when selecting the right abrasive material for your CNC drill bit
The chart below shows various grades of carbide in relation to Rockwell Hardness.
cnc drill bit materialCNC drilling is a machining process in which a computer numerical control (CNC) machine is used to drill holes into a material. This process is commonly used in creating precise and uniform holes in a variety of materials, including metals, plastics.
The CNC drilling process typically use a rotating spindle and a drill bit. The spindle is driven by a motor and controlled by the CNC machine, position the locations of holes and drill it.
CNC Drilling machine instruct the spindle movement and specifies the size and location of the holes to be drilled.
During the CNC drilling process, the material is held securely in place on the machine table, and the drill bit is carefully guided by the CNC machine to create the desired holes. The speed, depth, and angle of the drill bit can be precisely controlled by the CNC machine, allowing for high levels of accuracy and repeatability.
CNC drilling can be used to create a wide range of hole sizes and shapes, including round holes, square holes, and other complex geometries. This versatility makes CNC drilling a valuable tool in many manufacturing applications, including the production of tooling parts, assembly parts, and fabrication parts.
Asianstar offers CNC drilling services to our clients on turning parts or milling parts, programming the cutters to drill the holes, deburr the holes and prepare for thread turning, etc. Drilling process are usually used to supporting sheet metal fabrication.
Our CNC drilling service is ideal for industries such as aerospace, automotive, medical, and electronics, where precision and quality are of utmost importance. We can handle large volumes of orders and can work on a variety of materials, such as metals, plastics.
We offer our CNC drilling services at competitive prices and can provide quick lead time to meet our clients' deadlines. Our team can provide technical support and advice on the best drilling techniques and tools for your specific project.
