Mounting the DGp-2

t
9 . MOUNTING THE DGP-2
The DGP-2 stand alone grinder (without vacuum system and cabinet) should be mounted to a solid horizontal
surface (mounting hardware is not provided).
If mounted to a metal cabinet or pedestal, align the mounting holes with the corresponding holes in the cabinet
or pedestal. Insert a ¼"-20-1 ¼''hex head bolt with flat washer beneath the head of the grinder. From the bottom
of the cabinet or pedestal, place a ¼'' flat washer and ¼"-20 hex nut onto the bolt extension. Tighten only until
the space between the grinder base and the cabinet or pedestal is 1/8''. Using a second nut on each bolt, jam
tightens against the first to prevent loosening by vibration.
If mounted to a wooden bench top, use ¼'' wood screws that are 1 ¼'' long with flat washer beneath the heads.
Tighten screws until the space between the grinder base and the bench is 1/8''.
Electrode Grinding Assembly

1 0. ELECTRODE GRINDING ASSEMBLY

the Basics

The Electrode Grinding Assembly is attached to the right wheel housing (refer to Figure 1 for the general
arrangement of the assembly). It provides the means to support an electrode in a fixed position relative to the
diamond-grinding surface through an electrode guide collet that matches the electrode diameter. The electrode
is brought into gentle contact with the diamond-grinding surface and at the same time is rotated slowly in one
direction between the operator's thumb and forefinger. As an alternative, pin vises are also provided to hold the
tungsten during rotation. Note: all positioning and adjustment should be made before turning on the grinder.
Operation Instructions
Please refer to Figure 1 on the next page for the optimum location of the electrode point contact area with
respect to the grinding surface. In the position shown, the motion of the diamond grinding wheel surface is
parallel to the centerline of the electrode to accomplish longitudinal grinding of the electrode point. When
grinding very steep angles, such as 10°, be careful that the electrode guide collet does not make contact with
the diamond grinding wheel. This can contaminate the wheel and reduce the life of the wheel significantly. For
these types of angles, you may need to consult the factory to obtain optional short collets that available for
these applications.
Refer to Figure 2 on the next page for use with the following operation instructions:
1. If the tungsten you are using is already flat at the end, like new tungsten straight out of the box, proceed to
Step 4.
2. Locate the Point Flat Dresser Block (DGP-F180) attached at the 12 o'clock position of the right side wheel
cover. Find the hole that matches the diameter of your tungsten and turn on the grinder.
3. Select the electrode guide collet with the hole diameter closest to the tungsten electrode diameter and
position it in the electrode guide collet tube. Notice that the collet has been beveled on a 15° angle at the
front or exit end of the collet. With this surface parallel to the grinding wheel surface, tighten the set screw
to hold it in place. The back, or entrance, end of this collet has been milled down to its center line to make it
easy to insert the electrode for grinding.
4. Adjust the angular position of the electrode grinder assembly to the desired included angle of grind for the
electrode point using the angle adjustment handle (Handle A).
