FADAL MACHINING CENTERS
28 PRE-INSTALLATION PROCEDURES MAN-0126_R1
2.1 FOUNDATION WARNING!
The VMC MUST be placed on a surface that will support the combined weight of
the VMC, options, fixtures, and tooling, etc. (refer to the VMC Specifications section
at the beginning of this manual for VMC weights).
1. It is recommended that most models be placed on a isolated concrete pad 8-12”
thick. For VMC 6030 and larger the foundation pad should be 12-15”. (Figure 2-1:,
Dimension C). For A and B dimensions, see Table 2-1:Isolation Pad Dimensions.
Figure 2-1: Typical Pad Construction
2. The VMC should be positioned on a single slab. Placing the VMC over an
expansion joint may cause the VMC to shift when each individual slab moves.
3. The surface below the leveling pads should be free from cracks. Placing the VMC
over a crack may cause the VMC to shift during use. Inadequate flooring could
result in mechanical degradation.
4. Bolt the VMC directly to the pad through the .953” diameter holes that are provided
in the base casting. The dimensions for the base mounting holes of all machines
are in the VMC Specifications section (See Specifications, Section 1.0, MAN-0126
R1). Anchors are to be installed as shown below (Figure 2-2: Anchor Stud
