SECTION 3: SETUP Needed for Setup This machine presents serious injury hazards to untrained users. Read through this entire manual to become familiar with the controls and operations before starting the machine! Wear safety glasses during the entire setup process! The Model G0705 is a heavy machine. Serious personal injury may occur if safe moving methods are not used. To be safe, get assistance and use power equipment to move the shipping crate and remove the machine from the crate.
Inventory The following is a description of the main components shipped with your machine. A B Crate Contents (Figures 11 & 12) Qty A. Cabinet Base............................................... 1 B. Machine....................................................... 1 C. Toolbox........................................................ 1 D. Drill Chuck B16 1–13mm............................. 1 E. Drill Chuck Arbor R8–B16........................... 1 F. Lug Wrench................................................
Cleanup Gasoline and petroleum products have low flash points and can explode or cause fire if used to clean machinery. Avo i d u sing t h e s e p r o d u c t s to c l e a n m a c hin e r y. The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative has been your machine's close ally and guardian since it left the factory.
Site Considerations Weight Load Physical Environment Refer to the Machine Data Sheet for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.
Mounting Options Before you place your machine on the cabinet, we recommend you consider the following options for leveling and mounting it. Deciding on a method for mounting and leveling before placing the machine on the cabinet will make the process much safer and easier. Using the Included Leveling Bolt 1. Thread one M12-1.75 x 40 hex bolt with one M12-1.75 hex nut into the bolt mounting hole on each corner of the base, as shown in Figure 15. x4 Option 1: Use the included leveling bolts.
Using Machine Mounts Mounting to Shop Floor Using machine mounts, shown in Figure 16, gives the advantage of fast leveling and vibration reduction. The large size of the foot pads distributes the weight of the machine to reduce strain on the floor. Although not required, we recommend that you mount the cabinet to the floor. Because this is an optional step and floor materials may vary, mounting hardware is not included.
Mounting to a Workbench If you are placing the machine on an existing workbench, it must be securely attached to the workbench. The strongest mounting option is a "Through Mount" where holes are drilled all the way through the workbench, and hex bolts, washers, and hex nuts are used to secure machine to the workbench. Assembly Assembly of the Model G0705 consists of attaching the three handwheel handles to the machine. To assemble your machine: 1.
Moving & Placing Machine To move your machine into position: 1. 4. Unbolt the machine from the pallet, then with an assistant steadying the machine to prevent it from swinging, lift it slightly off of the pallet. Use the cross handwheel to move the table forward or backward as necessary to balance the machine so it hangs as close to level as possible. Move the shipping crate next to the workbench or cabinet. 5. Lift the machine and carefully place it onto the cabinet or workbench. 2.
Test Run Once the assembly is complete, test run your machine to make sure it runs properly and is ready for regular operation. The test run consists of verifying the following: 1) The motor powers up and runs correctly and 2) the stop button safety feature works correctly. If, during the test run, you cannot easily locate the source of an unusual noise or vibration, stop using the machine immediately, then review Troubleshooting on Page 41.
6. 7. Repeat Step 5 with the REVERSE button. The spindle should rotate in the opposite direction. 8. Press the EMERGENCY STOP button to stop the machine. Allow the spindle to stop rotating before proceeding. 9. Break-In Press the STOP button to stop the machine. Allow the spindle to stop rotating before proceeding. WITHOUT resetting the switch, press the FORWARD button. The machine should not start. —If the machine does not start, the EMERGENCY STOP button safety feature is working correctly.
SECTION 4: OPERATIONS Operation Overview To reduce the risk of serious injury when using this machine, read and understand this entire manual before beginning any operations. Damage to your eyes and lungs could result from using this machine without proper protective gear. Always wear safety glasses and a respirator when operating this machine. The purpose of this overview is to give the operator a basic understanding of how this machine operates—the big picture view of normal operations on this machine.
8. For milling operations, loosens the quill lock lever and uses the quill feed lever or the fine feed knob to set the cutting tool height according to the workpiece. Then, presses the FORWARD or REVERSE button to start the spindle and uses the table handwheels to move the table so the cutter removes material evenly from the workpiece.
Longitudinal Travel Handwheels: Control longitudinal (X-Axis) travel of the table. Head Crank: Changes the elevation of the entire headstock. Cross Travel Handwheel: Controls cross (Y-Axis) travel of the table. Table Locks: Lock the table in position along their respective axes. Travel Stops: Limit longitudinal table travel. Longitudinal Travel Handwheels Travel Stops Head Crank Figure 27. Head crank. Table Locks Cross Travel Handwheel Figure 25. Table travel controls.
Calculating Spindle Speed for Milling Before calculating the spindle speed for a milling operation, you must first understand the concept of "Cutting Speed" and how it differs from "Spindle Speed." Cutting speed is defined as the rate at which a cutting tool's edge passes across the surface of a workpiece. It is generally measured in "surface feet per minute" (sfm), which represents the theoretical distance the cutting edge would travel across the material in a straight line in one minute.
Speed Changes 3. Open the belt cover, then loosen the two idler cap screws (Figure 31) that hold the idler pulley in place so it can move freely. The Model G0705 is capable of twelve different speed settings. Different types of cuts and materials require varying speeds. Refer to the chart in Figure 29 for appropriate cutting speeds. Idler Cap Screws Tools Needed Qty Hex Wrench 6mm............................................... 1 To change spindle speeds: 1. DISCONNECT MACHINE FROM POWER! 2.
Calculating Spindle Speed for Drilling Using the Drill Bit Speed Chart Lubrication Suggestions The chart shown in Figure 33 is intended as a guide only. Always follow the manufacturer's speed recommendations if provided with your drill bits, cutters, or hole saws. Exceeding the recommended speeds may be dangerous to the operator. Wood............................................................None Plastics.............................................Soapy Water Brass................................
Spindle Height The Model G0705 has coarse downfeed levers and a micro-adjustment handwheel. To operate the downfeed levers, simply pull forward and down on the lever nearest you. The spindle will go down until you stop pulling or until it hits the depth stop. To operate the micro-adjustment handwheel: 1. Tighten the locking knob located on the center of the hub for the downfeed levers (Figure 34). This transfers control from the downfeed levers to the micro-adjustment handwheel.
Loading Tooling The Model G0705 features an R-8 spindle that accepts R-8 collets and arbors. 6. If you're using a collet, insert the cutter in the hole at the bottom of the collet. Be sure to protect your hands from the cutter with leather gloves or a shop rag. 7. To install tooling: 1. DISCONNECT MACHINE FROM POWER! —If the drawbar bottoms out in the tooling and will tighten no farther before the tooling is tight in the spindle, tighten the drawbar lock nut to secure the tooling in the spindle. 2.
Drill Chuck Arbor Collet Adapters Your machine includes an R-8 drill chuck arbor and MT#3 drill chuck. Before use, the drill chuck must be installed onto the arbor. This drill chuck installation is intended to be semi-permanent. The Model G0705 includes two adapters that will allow the use of MT#3 and MT#2 tooling. A drift key is also included to aid in the separation of the adapters and any installed tooling.
Headstock Position Depth Stop The headstock height and rotation on the Model G0705 can be adjusted for various applications. For increased quill rigidity and reduced vibrations, which will produce the best results, keep the quill fully retracted and set the headstock as low as possible. The depth stop is used to limit the range of downward movement by the drill bit or cutter. Maximum depth is 4 11⁄16". To calibrate the depth stop: 1.
Table Travel The mill/drill table moves in the longitudinal (X-axis) and cross (Y-axis) directions. Longitudinal Feed The handwheels shown in Figure 42 at each end of the table move the table longitudinally (X-axis). These handwheels will move the table in both directions. One complete revolution of either handwheel moves the longitudinal feed 0.100". A scale on the front of the table is used when a high tolerance is not required.
