Tailstock Column Installation

Type I Installation
Before proceeding to install the tailstock, make sure the Type I headstock is
already anchored to the floor. If it is not, refer to Section 4.2.
To install the tailstock onto a cell base or floor, proceed as follows:
1. Ensure the proper position of the headstock assembly per system layout. The
headstock must be permanently anchored to the floor/base.
2. Using a carpenter’s chalk string, strike a chalk line on the floor from the edge
of the headstock base toward the location of the tailstock (see Figure 4-12).
Figure 4-12 Strike Chalk Line
3. Set the tailstock in its approximate position on the floor using the chalk line.
The headstock and tailstock are now facing each other.
4. Measure the distance (D) between the headstock and tailstock base. To find
the distance (D) between the headstock base and tailstock base (see Figure 4-
13), use the following tailstock mounting formula:
D = PD + X (PD = Tooling pin-to-pin distance; X = MotoMount Offset)
NOTE:
The placement position derived from this formula will position the tailstock in the nominal
center position.
5. To find the X value in the tailstock mounting formula for your drive
assembly, locate the drive assembly model name in Table 4-3.
