Grinding machine with vacuum table

for removing excess plugging paste


The grinding machine SV-200 WV serves to remove the excess plugging paste from printed circuit boards and inner layers following the Via Hole Plugging process. That allows getting a flat uniform surface of the copper surface.
The grinding disk is driven by a servo motor, the x-y movement is manual by hand. SV 200 W

Plant description basic frame

The basic frame is made up of a stable welded stainless steel rack. The outer jacket is made up of canted stainless sheet metal sheets. All the sheets allow be opening with ease by entering catch locks and removing for allowing access.
The grinding head is covered with a hood with aluminium glass profiles. The plant is built up and designed such that all components are clearly arranged.

Belt filter system for circulated water (option)

Cooling water is transported via pump to the grinding head. On the bottom of the machine you can find the belt filter equipment, where the cooling water is filtered. 

Functional mode

The inner- or outer-layer of the printed circuit board is fixed on the aluminium working plate by vacuum.
The working area is protected by safety glass. The specific linear guides and the adjustable grinding pressure result in an excellent grinding performance and prevent the copper foil from possibly being ground through. The grinding head can be lowered to the printed circuit board with an exactness of 0,22 µm (0,0056 mil).
One turn (100 digits) equals 22µm (0,56 mil).

The result

Uniform surface with fine structure – the excellent grinding result is realized by the pressure-controlled rotation and the motion of the grinding head.

Further application fields of the grinding machine SV 200 WV:

  • Burring and grinding of holes (rigid printed circuit boards)
  • Grinding after panel plating
  • Grinding after pattern plating 
  • Cleaning and grinding of press plates

Control unit

The control unit is incorporated in a switch cupboard fastened to the basic frame.
The control element is made up of two different sections and elements, on the one hand the power pack and on the other hand the control unit itself.
The power pack contains the main contactors, fuses, semiconductor relays, protective motor switches and main power supply.
The control unit contains the plc-control, make Siemens.
