Description
PCB Drilling Machine DLCNC
We have developed four series drilling machine. They are D1/D2/D3/D4
D1: one Z axis with one or multiple spindles(max is 4 spindles), XYZ ball screw drive
D2: Independent Z axis, XYZ ball screw drive
D3: Independent Z axis, XYZ linear Motor
D4: Independent Z axis, XY linear Motor, Z axis ball screw drive

Drilling Accuracy
A good hole location accuracy is always convenient for following process and customer use, somehow, even makes up the downsides of following process management and control. But the picky on accuracy may cause lower work efficiency, hurt company and staff members’ interests.
Here we quote a concept “CPK“(Complex Process Capability Index). It’s the indicator to evaluate modern enterprise manufacturing capability. Normally require CPK≥1.33, this means production capability is steady and match the requirement. If CPK≥1.66, this means production capability is over requirement, need to adjust input and output.
We list some elements that may affect hole location accuracy.
First is equipment. Regular check and maintenance is necessary, detecting and wiping out the problems as early as possible is vital for keeping working accuracy.
The second is technics parameters, including pile hight, rotation speed, feed in and withdraw, working life, backup board material and hardness, cover board material and hardness, workpiece material and hardness.
The third is specific tool status, including tool grinding and control, pressure foot status, pin situation and vacuum pressure
The last is operators skill level. This is also very important part in the whole process.
Drilling precision is a very sophisticated and highly technological process. We rely on scientific, reasonable, precisely, correct thoughts to guide us, never just behave by feelings.
