A Excellent Tool for Precision Manufacturing - PCD Micro Drill
In the field of machining, drilling is a crucial process. However, when faced with materials with high hardness and wear resistance such as quartz, monocrystalline silicon, polycrystalline silicon, ceramics, and titanium alloys, especially when machining small holes with diameters ranging from 0.1mm to 3 mm, traditional methods often face a series of challenges such as chip removal difficulties, poor cooling effect, short drill life, and poor hole wall smoothness, and may even result in defects such as hole edge collapse, cracks, and burrs. These processing difficulties pose extremely high requirements for drill bit materials and drill tip design.
PCD micro drilling tools fully utilize the high hardness, wear resistance, and excellent thermal conductivity of diamond, effectively solving problems such as chip removal, cooling, and drill bit lifespan. At the same time, through precise drilling design, the smoothness of the hole wall and the integrity of the hole mouth are ensured, greatly reducing the occurrence of defects such as edge collapse, cracks, and burrs. The PCD micro drill series is widely used in fields such as semiconductors, aerospace, 3C industry, chips, and medical devices.
Significant advantages of PCDmicro drilling tools:
1. Long service life: The drill tip made of integral diamond technology has much higher hardness and wear resistance than hard alloy drill bits, especially when processing difficult to machine materials such as monocrystalline silicon, polycrystalline silicon, ceramics, quartz, etc. PCD micro drills can significantly extend the tool's service life.
2. Good drilling accuracy: The specially designed drill tip and production accuracy of up to 5 μ m ensure that the diameter tolerance, roundness, and straightness of the hole can meet the high-precision requirements.
3. Excellent hole quality: The PCD drill tip has the characteristics of low friction coefficient and low affinity with non-ferrous and non-metallic materials, effectively reducing chip deposits and maintaining the smoothness of the hole wall. When processing hard and brittle materials, it is not easy to produce hole edge collapse and cracks; When processing adhesive materials, defects such as burrs at the hole opening can also be avoided.
4. High depth to diameter ratio: The self centering design of the drill tip, optimized chip removal groove, cutting edge, and special helix angle enable different series of PCD micro drills to meet different depth to diameter ratio requirements.
PCD micro drilling tools not only meet the demand for high-precision small holes in special fields, but also bring efficient solutions to the machining industry. Through continuous optimization, they ensure excellent performance and stability of the tools, improve machining efficiency and quality.
