Working With Vacuum Tables and Spoil Boards (Cont’d.) -
Functions of the Spoil Board-
1)To protect the vacuum table from damage. The cutter extends only a few thousandths of an inch past the material
thickness. Without the spoil board, the cutters could damage the surface of the vacuum table.
2)To transfer the vacuum from the table to the job. This means that the spoil board has to be porous to allow air
flow to the panel material. Low cost MDF (Medium-Density Fiberboard) has proven to be a very good material for
this purpose.
3) To provide a “Zero Setup” environment for processing panel products.
Spoil Board Preparation-
When MDF is sourced for the spoil board, it should be (>) greater than ¾” of an inch.
Contrary to what might seem logical, the thicker the MDF the better the suction that is created.
“Flow - Through” fixturing maintains a careful balance between air flow through the MDF and the infiltration that
occurs as the kerfs (Grooves or Notches made by a cutting tool
)
are machined.
***It is not recommended that the spoil board material be is thicker than 1 inch***.
The MDF manufacturing process causes the top and bottom surfaces of the material to be compressed. It is
necessary, therefore, to remove the compacted top and bottom surfaces.
This process is termed “fly - cutting” and requires the removal of approximately 0.060" from each surface. This
process also ensures that the machining plane and spoil board surface are parallel.
