SECTION 4: OPERATIONS Operation Overview The purpose of this overview is to provide the novice machine operator with a basic understanding of how the machine is used during operation, so the machine controls/components discussed later in this manual are easier to understand. Due to the generic nature of this overview, it is not intended to be an instructional guide.
Digital Readout Unit The digital readout unit gives a precise reading of the vertical positioning of the quill. It can be zeroed at any position and manually increased or decreased independent of quill position when the operation requires it (Figure 22). OFF Button ON/0 Button IN/MM Button To use the digital readout: 1. 2. Press the IN/MM button to select whether units will be displayed in inches or millimeters. Each press of the button switches from one unit to the other. 3.
Calculating Spindle Speed Closely follow the proper spindle speed and proper feed rate to produce good results, reduce undue strain on all moving parts and increase operator safety. Prior to milling, determine the spindle speed needed to cut your workpiece, then set the speed on the machine. To determine the needed spindle speed: 1. Use the table in Figure 23 to determine the cutting speed required for the material of your workpiece. 2. Measure the diameter of your cutting tool in inches. 3.
Spindle Speed and Direction Note: It may be necessary to rotate the spindle by hand to get the gears to mesh properly. 3. Setting the speed on the Model G0704 is a two part process. The gearbox in the headstock has two gear ranges and the motor is a variable speed unit. Together, these two systems provide an overall speed range of 50–2250 RPM. To set the spindle speed: 1. Make sure the work area is clear and that all safety precautions are taken. 4.
Spindle Height Controls The spindle height is controlled by the quill feed lever and the fine feed knob. Fine Feed Knob Changing Spindle Position Using Fine Feed Knob 1. Unlock the quill lock lever and tighten the fine feed lock knob. 2. Rotate the fine feed knob to lower or raise the spindle in small increments. Observe the scale on the knob or the digital readout to monitor movement in thousandths of an inch (Figure 27).
Drill Chuck To install the drill chuck and arbor: 1. DISCONNECT MILL/DRILL FROM POWER! 2. Remove the drawbar cap. 3. Insert the chuck arbor into the spindle, making sure to line up the slot in the arbor with the pin in the spindle. 4. Thread the drawbar into the arbor until the arbor is seated up into the spindle taper. 5. Use a 17mm wrench to prevent the spindle from turning while you use an 8mm wrench to snug the drawbar, as shown in Figure 28. Figure 28. Snugging the drawbar.
Loading Tooling Your Model G0704 features an R-8 spindle taper, which gives the freedom to use standard R-8 cutting tools and collets. These optional collets come in many sizes, typically ranging from 1⁄ 16" to 7 ⁄ 8" and 3mm to 20mm, and should be matched to your cutting tool shank size. To install the tooling: 1. DISCONNECT MILL/DRILL FROM POWER! To remove the collet: 1. DISCONNECT MILL/DRILL FROM POWER! 2. Remove the drawbar cap. 3. Lock the quill in place with the quill lock lever. 4.

Gibs Gibs are wedge-shaped pieces of metal that fill the gap between the sliding surfaces of the machine. By adjusting the position of the gib in its gap, you can remove any play that might exist between the adjacent components. The gibs are pre-adjusted at the factory but due to storage, break-in, and usage, may require adjustment. If movement seems too tight at first, make sure that all the rust preventative that was shipped on the machine is removed from the ways.
Leadscrew Backlash When you turn the handwheels to adjust the position of the table, you will notice slight play (backlash) in the handwheel before the table begins to move. If this play is greater than 0.008" (measured with the dial at the base of each handwheel), then you will need to adjust the leadscrew nuts. To reach the adjustment screws on the leadscrew nut, you may have to fabricate extensions for your hex wrenches. When adjusting, make adjustments in small increments.
Motor Service 3. Unscrew one of the brush caps to expose the brush assembly (Figure 59). The bearings inside the motor are shielded and lubricated for the life of the bearing and require no routine maintenance. This motor is equipped with long life carbon brushes. Brush life expectancy is affected by motor loading. Heavy motor loading will result in reduced brush life. If you notice a loss in power or if the motor becomes excessively noisy, inspect the brushes.
