How can the efficiency of CNC Planar Drilling Machine be improved?

CNC Planar Drilling Machine printed board drilling bit is generally used carbide, because the epoxy glass cloth copper foil plate wear the tool particularly fast.

The so-called cemented carbide is made of tungsten carbide powder as matrix and cobalt powder as binder by pressure and sintering. Usually containing tungsten carbide 94%, 

cobalt 6%. Because of its high hardness, very wear-resistant, has a certain strength, suitable for high-speed cutting. Poor toughness, very brittle, in order to improve the performance of 

cemented carbide, some use chemical vapor deposition on the carbide matrix of a layer of 5 to 7 microns of titanium carbide (TIC) or titanium nitride (TIN), so that it has a higher hardness. 

Some use ion implantation technology to inject titanium, nitrogen, and carbon into the matrix to a certain depth, which not only improves the hardness and strength, but also migrates these 

injected components when the bit is reground. There is also a physical method to generate a diamond film on the top of the bit, which greatly improves the hardness and wear resistance of 

the bit. The hardness and strength of cemented carbide are not only related to the ratio of tungsten carbide and cobalt, but also related to the particles of the powder. When the substrate 

layer is not high, the use of drill sleeve can avoid drilling deviation.

At present, most manufacturers use CNC Planar Drilling Machine, CNC Planar Drilling Machine uses cemented carbide fixed shank drill, which is characterized by automatic bit replacement. 

High positioning accuracy, no need to use drill sleeve. Large spiral Angle, fast chip removal speed, suitable for high-speed cutting. In the full length range of the chute, the drill bit diameter 

is an inverted cone, the friction with the hole wall is small, and the drilling quality is high. Common shank diameters are 3.00mm and 3.175mm.

CNC Planar Drilling Machine using computer control, drilling machining is the key is the positioning accuracy of the hole. The machining mode of this CNC Planar Drilling Machine is widely 

used in all walks of life, and its obvious advantages are favored by everyone.

CNC Planar Drilling Machine reduces the manual, the traditional hole processing positioning method, relying on technical workers to draw lines according to the drawings, and then use the 

electric hand drill or magnetic drill to drill the positioning hole, so the operation of low efficiency, the error is relatively large. Now the use of CNC Planar Drilling Machine only needs to input 

specific parameters through the computer, according to the correct CAD design drawing, with a professional device to find three points on the workpiece, you can realize the automatic 

continuous large aperture machining of the drilling power head, the convenience of operation has been improved, to ensure the high accuracy and high stability of the product. Nc surface 

drilling has high efficiency

The CNC Planar Drilling Machine is also much higher than the traditional manual hole machining in terms of efficiency. When CNC surface drilling machining, save two labor costs. This 

process takes only 0.5 hours to complete. The work efficiency and the economic benefit of the enterprise can be improved.

The traditional manual hole processing, marking, drilling, proofing and positioning, drilling and tapping all need a person. In this way, the overall estimate is that the processing time of a 

tube plate reaches 3.0 hours. The average size of tungsten carbide phase grains is less than 1 micron. This kind of drill has not only high hardness but also improved compressive and 

bending strength. In order to save costs, many drill bits now use welded shank structure, the original drill bit as a whole is cemented carbide, and now the rear drill shank is made of 

stainless steel, and the cost is greatly reduced
