SETUP UNPACKING Before setting up your machine you must read and understand the instructions given in this manual. To ensure safe transportation this machine is properly packaged and shipped completely in crates. When unpacking, carefully inspect the crates and ensure that nothing has been damaged during transit. Open the crates and check that the machine and the parts are in good condition.
PROPER GROUNDING Grounding provides a path of least resistance for electric current to reduce the risk of electric shock. CX704 is for use on a normal 110 volt circuit. Make sure that the machine is connected to an outlet having the same configuration as the plug. If an adaptor plug is used, it must be attached to the metal screw of the receptacle. To prevent electrical hazards, have a qualified electrician ensure that the line is properly wired.
HAND WHEEL HANDLES Thread the handles into the longitudinal and tailstock handwheels and tighten using a screw driver and an open wrench. See figure-2 & 3. Figure-4 Installing the cross feed hand wheel handle BASIC CONTROLS Figure-2 Installing the tailstock hand wheel handle Figure-3 Installing longitudinal hand wheel handle The cross slide feed handle comes installed with the opposite direction for shipping purposes. Remove the cap srew using a hex wrench and turn the handle around.
C. FORWARD/REVERSE SWITCH: Changes the direction of rotation of spindle from clockwise to neutral and counterclockwise. D. EMERGENCY STOP BUTTON: Shuts down the power to the motor when pushed in. TEST RUN Once you have assembled your machine completely, it is then time for a test run to make sure that the machine works properly and is ready for operation.
off the machine and investigate to find out the problem. If the lathe is running smoothly, let it run for a few minutes and gradually increase the RPM using the variable speed control knob until it reaches the maximum RPM of 2500. Allow the lathe to run for a few minutes and stop it by pressing the Emergency Stop Button. WARNING! DO NOT change the direction of rotation of leadscrew while the lathe is running. Failure to do so could result damage to the lathe.
Tap the chuck / faceplate with a rubber mallet (if needed) and pull it out. TAILSTOCK POSITIONING TO ADJUST THE LONGITUDINALLY: TO INSTALL THE CHUCK / FACEPLATE: Remove the studs from the old faceplate / chuck you just removed and thread them into the faceplate / chuck you want to install. Make sure the cord is disconnected from the power source. Loosen the tailstock lock nut securing the tailstock on the lathe bed with a proper size wrench. See figure-9.
Repeat the above steps often to change the tailstock offset. DEAD CENTER TO USE THE TOOL POST: Attach the cutting tool you want to use to the tool post and secure it by tightening cap screws. See figure-10. When the work-piece is 3 times longer than its diameter should be supported by a dead or live center. TO INSTALL THE DEAD CENTER: Make sure the cord is disconnected from the power source. Turn the tailstock hand wheel so that the quill is about 1" out.
Position the steady rest on the lathe bed where desired and secure it in place by tightening the nut. CROSS SLIDE The cross slide allows the cutting tool to travel perpendicular to the bed and features a scale and a hand wheel having graduations of 0.001". TO ADJUST THE CROSS SLIDE: Move the cross slide back and forth a few turns using the hand wheel and then move it to your starting point. This will clear any free movements in the leadscrew increasing accuracy on cross slide scale.
COMPOUND SLIDE MANUAL MOVEMENT The compound slide rotates at a set angle and features a graduation scale of 0.001". The manual movement of the carriage can be controlled using the hand wheel shown in figure-14. TO ADJUST THE COMPOUND SLIDE: Loosen the bolts located on the compound slide shown in figure-13.
TO CHANGE THE GEARS: Make sure the cord is disconnected from the power source. Remove the gear cover to access the gears. Loosen the adjusted to disengage the gears from each other. Remove the gears and install the new gears according to the chart. See figure-17 & 18. Figure-15 Automatic feed lever Reinstall the adjuster and close the close the cover. WARNING! DO NOT change the direction of rotation of leadscrew while the lathe is running. Failure to do so could result damage to the lathe.
THREADS CUTTING Several different threads can be cut using the proper combination of gears and settings. MAINTENANCE During the life of your machine, you will need to practice some regular maintenance to keep your lathe in peak performance condition. Set the compound slide to the proper angle required for the cut and align the tip of the cutting tool with the center of the workpiece.
Every day, after the operation, eliminate all the chips and clean different parts of the machine tool and apply machine tool oil to prevent from rusting. Good housekeeping practice should be followed on a daily basis keeping your lathe clean and well lubricated. GIBS ADJUSTMENT The cross slide and the compound slide gibs will need to be adjusted after sometimes. TO ADJUST THE CROSS-SLIDE AND COMPOUND SLIDE GIBS: Disconnect the cord from the power source.
MOTOR BRUSHES REPLACEMENT TO REPLACE THE MOTOR BRUSHES: TO CHECK THE CENTERS ALIGNMENT: Center drill a 6" piece of bar stock on one end and position it between the headstock and tailstock as shown in figure-22. Make sure the cord is disconnected from the power source. Remove the front and rear caps shown in figure-21. Figure-22 checking headstock and tailstock alignment Turn approximately 0.010" off diameter. Figure-21 Front motor brush cap Measure the stock with a micrometer.
Figure-24 Stock thinner at the tailstock end TO MOVE THE TAILSTOCK: Make sure the switch is in the OFF position and the cord is disconnected from the power outlet. Adjust the tailstock offset half the amount by turning the offset screw. Turn another 0.010" off the stock and check for taper. Repeat this procedure until the tailstock is aligned with the headstock.
