Grizzly G9249 Centers, Using the Faceplate, Installing a Sleeve and Center into the Spindle

Page 28

Always use a low spindle speed when machining non-cylindrical or off-center workpieces to avoid ejecting the workpiece from the holding device at a high rate of speed. Failure to heed this warning could lead to serious personal injury or property damage.

Using the Faceplate

The faceplate can be used to turn non-cylindrical parts or for off-center turning by clamping the workpiece to it.

To mount a workpiece on the faceplate:

1.DISCONNECT LATHE FROM POWER!

2.Use a piece of wood to protect the bedways.

3.Secure the workpiece on the faceplate with a minimum of three independent clamping devices (see Figure 30 for an example).

Note: Take into account the rotation and cutting forces that will be applied to the workpiece when clamping it to the faceplate.

Centers

The Model G9249 includes one MT#3 live center and two MT#3 dead centers (see Figure 31). The supplied MT#5–MT#3 spindle sleeve fits into the spindle taper to hold an MT#3 center or tool.

The live center tip will rotate independently of the spindle or quill. The dead centers will spin with the spindle and remain stationary when used in the quill. Use these devices as required by your operation.

The steps to install and remove a center into the tailstock quill are detailed in the previous Tailstock subsection on Page 27.

Installing a Sleeve and Center into the Spindle

1.Clean away any grime or oily substance from the tapered mating surfaces of the sleeve and center.

2.Install the center into the spindle sleeve, then seat the assembly into the spindle.
