Microdrilling is a machining process that uses a small drill bit to create precise holes in a variety of materials. More commonly, It is often used in the production of medical equipment manufacturing, automotive parts, mold and die making, and electronics. In these areas, small hole drilling with a diameter of 0.1 to 3 mm is often required. Examples include drilled small holes for cooling, lubrication, venting, or nozzle bores.
It is a highly precise process that can produce holes with a high degree of accuracy, that involves using a high-speed spindle to rotate the drill bit at high speeds (the speed range of DOBEMY is 1500rpm-60000rpm), while a coolant is used to keep the bit from overheating. The drill bit is then guided through the material, creating a hole with a diameter of 0.1 mm or less. Drilling experts generally make the term « micro drilling » to describe the drilling of holes smaller than 3 mm in diameter, Our diameter range of the drilling machine is 0.1 mm -3 mm.
Advantages of micro drilling
As one of the drilling processes, Microdrilling uses a small drill bit to create very small holes in a variety of materials. This process has several advantages over traditional drilling methods, such as:
- Time savings – Microdrilling is much faster than traditional drilling methods, as the drill bit is much smaller and can create holes in a fraction of the time. Especially the open structure of our machine is convenient for loading and unloading, can be set up for multi-station processing, and can be processed in a cycle of changing materials without stopping.
- High precision -Microdrilling is more accurate than traditional drilling methods, as the drill bit is much smaller and can create very precise holes with a diameter of 0.1 mm or less, Full servo motor drive with good repeat positioning accuracy of our auto CNC microdrilling machine can reach ≤0.01 mm.
- Cost-effectiveness – Microdrilling is much more cost-effective than traditional drilling methods, as the drill bit is much smaller and requires less energy to create the holes, due to its higher precision and lower material waste
- Flexibility – Microdrilling can be used for a variety of materials, including metals, stainless steel, mild steel, brass, copper, iron, ceramics, etc. This makes it a great option for a variety of applications.
- Reduced risk of damage – Microdrilling is less likely to cause damage to the material being drilled, as it is a much more precise process.
- Environmentally and friendly – Microdrilling is much safer and more environmentally than traditional drilling methods, and produces less waste to create small holes, making it a more environmentally friendly option.
Type of micro drilling machine
There are several types of microdrilling machines, including:
CNC Microdrilling Machines: These machines use computer numerical control (CNC) technology to precisely drill small holes in materials such as metal, plastic, and wood. They are typically used for precision drilling applications, such as creating small holes for electronic components.
Ultrasonic Microdrilling Machines: These machines use ultrasonic vibrations to drill small holes in materials. They are typically used for drilling small holes in hard materials such as metals and ceramics.
Laser Microdrilling Machines: These machines use a laser beam to drill small holes in materials. They are typically used for drilling small holes in materials such as plastics, metals, and ceramics.
Each type of machine has its advantages and disadvantages, and the best choice for a particular application will depend on the material being drilled and the desired accuracy of the holes. Our machines with multi-function including integrating milling, drilling, and chamfering, also provide OEM and ODM services.
