VMC850B machining center with GSK218MC-H CNC system to process thin plates with overall dimensions of length X width X thickness (mm): 496X296X3, requiring a large area of 426X205X1 sinks on the board as positioning and some automatic tinning through slots When milling the 1mm positioning sink, the part clamping must not have arching, so as to prevent tin leakage when it is affected.

solution 

The heat of synthetic stone processing is large, and cooling must be in place;

Positioning method: using bolts, three-point positioning;

Clamping method: base plate + pressure block;

Machine tool requirements: machine tool horizontal deviation ≤0.02mm, Z axis vertical error ≤0.02mm;

Tool requirements: PCB corn milling cutter is used for roughing;

During the rough machining of the PCB corn milling cutter, the cutting method is used to mill from the inside to the outside to reduce the problem of insufficient rigidity.

Application effect

Strong interchangeability of tooling, suitable for processing of various wave soldering fixtures;

Special props have good cutting ability, less processing deformation, and reduce the problem of solder leakage.

Equipment processing is stable to improve the durability of the product.
