PCB Mechanical drilling

The technical parameters of a PCB drilling machine are important indicators to measure its performance and processing capabilities. Here are some common technical parameters:
Stroke: It refers to the moving range of each axis of the drilling machine, usually expressed by the strokes of the X, Y, and Z axes. For example, the stroke of the Guangdong Kejie KJ - 2 PCB drilling machine is X×Y×Z = 290/500/50mm. The X - axis stroke of the Ende Technology PK - 2228/S6 is 550mm, the Y - axis stroke is 700mm, and the Z - axis stroke is 35mm.
Spindle speed: The rotational speed of the spindle, with the unit of rpm (revolutions per minute). A high - speed spindle can improve drilling efficiency and quality. For instance, the maximum spindle speed of the Guangdong Kejie KJ - 2 PCB drilling machine can reach 160000rpm. The spindle speeds of Ende Technology PK - 2630/S1 and other models can reach 160K/180K/200K rpm.
Spindle power: The power of the spindle motor. The larger the power, the stronger the cutting ability of the spindle. The spindle powers of different models of PCB drilling machines vary. For example, the power of the Ende Technology PK series drilling machines at 60000rpm is 402/400/441 (specific values vary by model).
Moving speed: It includes the maximum moving speed and the maximum processing speed. The maximum moving speed refers to the fast - moving speed of the axis in a non - processing state. For example, the maximum moving speeds of the X/Y/Z axes of the Guangdong Kejie KJ - 2 PCB drilling machine are 35/35/30m/min. The maximum processing speed refers to the actual moving speed of the axis during processing. The maximum processing speeds of the X/Y/Z axes of the KJ - 2 PCB drilling machine are 1.2/1.2/3m/min.
Positioning accuracy: It is the accuracy of the drilling machine in drilling at a specified position, usually expressed as ±mm. Generally, the positioning accuracy of a PCB drilling machine is around ±0.005mm. For example, both the Guangdong Kejie KJ - 2 PCB drilling machine and the Ende Technology PK series drilling machines have a positioning accuracy of ±0.005mm.
Repeat positioning accuracy: It is the accuracy consistency of the drilling machine when drilling at the same position multiple times, usually expressed as ±mm. The common repeat positioning accuracy of PCB drilling machines is ±0.0025mm. For example, both the Guangdong Kejie KJ - 2 PCB drilling machine and the Ende Technology PK series drilling machines have this repeat positioning accuracy.
Drilling accuracy: It refers to the deviation degree between the actual size of the hole after drilling and the designed size, usually expressed as ±mm. For example, the drilling accuracy of the Dongtai Precision Machinery TR - 522 (523) ultra - high - speed PCB drilling machine is ±0.05mm.
Tool magazine capacity: The number of drill bits that the tool magazine of the drilling machine can hold. For example, the tool magazine capacity of the Guangdong Kejie KJ - 2 PCB drilling machine is 250 bits, and that of the Ende Technology PK - 2630/S1 and other models is 450 bits.
Drill bit size: The range of drill bit diameters that the drilling machine can use, generally 0.1 - 6.35mm. For example, the drill bit size range of the Ende Technology PK series drilling machines is this value. The drill bit diameter of the Dongtai Precision Machinery TR - 522 (523) is 0.75 - 3.175mm.
