6.0 General description and nomenclature Figure 2 – General Description (GH-2680ZH shown) Feed Gearbox The ZH series lathe operates on a centralized gear system. The motor power is transferred through four v-belts to a shaft, which in turn transmits the energy through a multi-disc friction clutch and various gear pairs, to the spindle. The clutch also controls the spindle’s direction of rotation.
Steady Rest Compound Rest. The compound rest (I), which is T-slotted and mounted on the cross slide, can be rotated 360°, allowing tapers to be turned. The compound rest travels on dovetailed ways, with adjustable gibs. The ZH series lathes are provided with small and large steady rests (T). A steady rest serves as a support for shafts on the free tailstock end. The steady rest is mounted on the bedway and secured from below with a bolt, nut and locking plate. Quick Change Tool Post.
1 7.0 Unpacking Open shipping container and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Latheis set up and running properly. Compare the contents of your container with the following parts list to make sure all parts are intact. Missing parts, if any, should be reported to your distributor. Read the instruction manual thoroughly for set up, maintenance and safety instructions. 7.
8.0 Installation 1. Finish removing all crate material from around lathe. 2. Unbolt lathe from shipping pallet. 3. Choose a location for the lathe that is dry and has sufficient illumination. 4. Allow enough room to service the lathe on all four sides, and to load and off-load work pieces. In addition, if bar work is to be performed, allow enough space for stock to extend out the headstock end. If used in production operations, leave enough space for stacking unfinished and finished parts. 5.
8.3 Chuck Preparation 5. Read and understand all directions for chuck preparation. Failure to comply may cause serious injury and/or damage to the lathe. Lift the chuck up to the spindle nose and press onto the spindle. Tighten in place by turning the camlocks 1/4 turn clockwise. The index mark (A, Figure 7) on the camlock should be between the two indicator arrows (B) when tight, as shown in Figure 7. The three-jaw scroll chuck is shipped pre-installed on the lathe.
9.0 Maintenance/Lubrication Lathe must be serviced at all lubrication points and all reservoirs filled to operating level before the lathe is put into service. Failure to comply may cause serious damage to the lathe. The ZH series lathe is shipped with oil in the reservoirs. Coolant is not included. Use clean lubricants and check levels often, including before each working shift. To ensure proper lubrication, oil levels should not be less than the center of the oil sight glass.
through various oil lines to lubricate the ways below the saddle. Perform this several times daily. 8. Threading Dial – Frequently lubricate via one ball oiler (P, Figure 11) on top of the dial with SAE 20W oil. 9. Cross Slide – Daily lubricate one ball oiler on the handwheel housing (L, Figure 11)and three ball oilers on the platform (K, Figure 12), with SAE 20W oil. Figure 10 – Oil filter access 4.
GH-26120ZH: Pour coolant (approx. four gallons) into one of the chip trays (Figure 16). Or, slide out one of the chip trays and pour directly into the side trough on the center stand. 2. After machine has been connected to power, turn on coolant pump and check to see that coolant is cycling properly. Flow is controlled by the tap at the base of the nozzle. 3. Reinstall access cover or chip tray. Figure 14 – Lubrication points 14.

GH-26120ZH: 1) Remove top panel inside the bed (Figure 19). 2) Remove rear panel on center stand then remove the two socket head screws (Figure 20) that secure the plate on which the coolant pump is mounted. Figure 17 – Power input 10.1 Conversion to 460 Volt Operation Disconnect machine from power source. Failure to do so may cause serious or fatal injury.
NOTE: Lathe will still have power. Twist button clockwise to reset. • ON Button (C, Figure 22 and 23). Activates motor. • Coolant On-Off Switch (D, Figure 22). Activates coolant pump. 2. Speed Selection Levers (E, Figure 22): Located on front of headstock. Move levers left or right to desired spindle speed, according to accompanying chart on the dial. 3. Feed Direction Lever (F, Figure 22): Located on front of headstock. Moving the lever changes direction of feed. Center position is neutral.
I/II/III/IV = The leadscrew is used to cut thread forms. A/B/C/D = The feed rodis used to control the feed/revolution. The ratios between them are: I: II: III: IV: = A:B:C:D = 1:2:4:8 Figure 25 9. Spindle Direction Control Lever (M, Figure 24). Move lever to the right so that its tab clears the notch, then down for forward spindle rotation, or up for reverse spindle rotation. Allow spindle to come to a stop before changing directions.
21. Travel Setting Rod (Y, Figure 27): Up to six pre-set configurations are possible for repetitive operations, without having to reposition the stops each time. Use the knurled knob at the right end of the rod to set the rod at one of six positions shown on the dial. Then move the desired number of eccentric stops into position for that particular operation and tighten them securely to the rod with the screws beneath them. When the apron trip lever contacts a stop, the clutch will disengage. 12.
the point of the tailstock center as a gauge and shims under the tool to obtain the correct center height. Use a minimum of two clamping screws to secure each tool. 12.2 Spindle Speed Twelve speeds are available by placing the first speed lever (E1, Figure 31) in one of four positions, and placing second lever (E2) in a position that matches the color for the range you desire. These selections are identified on the lever hub, as well as in Table 6, section 16.3.
12.4 Thread Cutting 13.0 Adjustments Threading is performed in multiple passes, with an initial cutting depth of about 0.2 mm, and decreasing depth in succeeding cuts. It is recommended that test cuts be made on scrap material and the results checked before proceeding with regular material. 1. Adjustments to the lathe, especially those involving alignments of bearings, spindle, leadscrew, clutch, etc.
3. Alternately loosen and tighten front and rear screws (C). (only front screw shown.) The scale (D) on the end of the tailstock indicates amount of offset, and helps when re-centering. Figure 35– Saddle sliding plate adjustment Figure 38 – Tailstock adjustments If the clamping force needs to be adjusted, use the hex nut (E, Figure 39). When the clamping lever is released, the tailstock “floats” upward approximately 0.05 to 0.
Figure 40 – Gap section Figure 41 – Belt and brake strap adjustment To reinstall the gap section: 4. 13.6 Brake Strap Clean the bottom and the ends of the gap section thoroughly. 5. Set gap section in place and align the ends. 6. Insert the tapered pins into their holes through the gap and into the lathe bed. 7. Reinstall the six bolts (B/C), and tighten alternately until all are snug. Make sure gap remains aligned with the ways while tightening the screws.
Figure 43 – Spindle Clutch Adjustment 1. Figure 44 – Tailstock/Headstock alignment 13.9 Spindle Bearings Make sure the lathe is OFF at the master switch. 2. Remove the top cover of the headstock. 3.

Rotate the adjusting nut to the next index position, which will be indicated by a “click.
Figure 46 – Speed control chain adjustment 13.11 Lead Screw To ensure the pitch accuracy in cutting threads, any axial run-out of the lead screw must be eliminated. See Figure 47. This is achieved by adjusting the thrust bearings (2 and 3) using the nut (1). Figure 48 – Feed clutch adjustment 13.13 Tool Post Tool holder (2) is positioned to the tool post body (1) through a dovetail groove and its center height can be adjusted by sliding the dovetail along the groove and turning screw (5).
Figure 50 – Cross slide nut adjustment 13.15 Shear Pin Replacement The lead screw and feed shaft are equipped with shear pins, which are designed to break in order to protect the drive system against overload. A broken shear pin must be replaced. Knock out the broken pin; line up the holes and insert new pin. 13.16 Steady Rest Adjustment Always grease the fingers before using the steady rest. The point at which the fingers contact the workpiece require continuous lubrication to prevent premature wear.
13.17 Follow Rest Adjustment The follow rest mounts to the saddle with two socket head cap bolts. The follow rest should be mounted so that the locking knobs point away from the chuck. The sliding fingers are set similar to those on the steady rest – free of play, but not binding. Always lubricate the fingers sufficiently with grease before operating.
14.0 Troubleshooting the ZH Series Lathes Table 2 Trouble Lathe will not start. Spindle lacks turning power; or starts up slowly. Excessive machine vibration. Lathe overheating. Tool tip burns. Lathe turns a taper. No automatic power feed. Carriage, cross slide or compound rest move with difficulty. Probable Cause Remedy No electrical power, or wiring incorrect. Verify incoming power, main leads, main switch is on. Emergency stop switch is pressed. Rotate switch clockwise to release.
15.0 Lubrication Schedule and General Maintenance Regularly scheduled maintenance is crucial to ensure a long service life for your machine. The schedule below shows general cleaning, lubrication points and coolant replacement information for the ZH Series Lathes. Push stop button and power off before lubricating.
