Read and understand all assembly instructions before attempting assembly. Failure to comply may cause serious injury. 6.0 Setup and assembly 6.1 Shipping contents See Figure 6-1.
7. With proper lifting equipment, slowly raise lathe off shipping pallet. (See Figure 6-2). Do not lift lathe by the spindle. Do not place slings around bed – this can bend leadscrew and feed shaft. Figure 6-3 6.4 Completing installation Figure 6-2 8. The lathe may be installed free-standing or bolted to the foundation: Exposed metal surfaces have been treated with an anti-corrosion coating. Remove this using a soft rag and mild commercial solvent or kerosene.
To remove chuck or faceplate: 6.6 Break-in period 1. Do not run lathe above 560 RPM for first six hours of operation, to allow gears and bearings to adapt and run smoothly. Support the chuck while turning three camlocks 1/4-turn counterclockwise using the chuck wrench from toolbox. See Figure 6-5. Line up the two marks for removal. 7.0 Lubrication Lathe must be serviced at all lubrication points and all reservoirs filled to operating level before lathe is placed into service.
apron. Drain oil completely and refill after first three months of operation. Then, change oil in the apron annually. Figure 7-2 3. External Gears – Coat all gears (Figure 7-3) with a heavy, non-slinging grease. Figure 7-4 (cutting tool not provided) 6. Saddle – Daily lubricate four ball oilers (O, Figure 7-4 and 7-5). The anti-dust wipers on both ends of saddle (K, Figure 7-4) should be cleaned weekly with kerosene. If a wiper becomes damaged, replace it. 7.
11. Leadscrew – Lubricate ball oiler (R, Figure 76) once daily. 8.0 Electrical connections Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded while in use to help protect the operator from electrical shock and possible fatal injury. The lathe is rated for 230 volt, 3-phase incoming power. Confirm that power available at the lathe’s location is the same rating as the lathe.
Power Indicator Light (A, Figure 9-1). Illuminates whenever lathe is receiving electrical current. Coolant On-Off Switch (B, Figure 9-1). Activates coolant pump. Jog/Toggle Button (C, Figure 9-1). Quickly press and release to briefly rotate spindle. Emergency Stop Button (D, Figure 9-1). Shuts down all machine functions. NOTE: Lathe will still have power. Twist button clockwise to reset. Variable Speed Dial (E, Figure 9-1). Adjust speed based upon range selected.
. Top Slide Handwheel (U, Figure 9-2): Rotate to position rest. The accompanying scale on collar is graduated in 0.001 inch increments. 10.0 Operation The operator should consult shop manuals such as “Machinery’s Handbook” for cutting speeds and feeds appropriate to specific workpieces. Correct feed depends upon material to be cut, cutting operation, tool type, chucking rigidity, depth of cut, and desired surface quality. 17.
Figure 10-2 Avoid short clamping contact (A, Figure 10-3) or clamping on a minor part diameter (B, Figure 10-3). Face-locate the workpiece for added support. Figure 10-4 Figure 10-3 10.1 Feed and Thread Selection To obtain various feed settings and thread pitches, the knob and two levers (J, Figure 10-4) are used conjunctively. Position the levers according to the Feed and Thread Chart on front of end cover. An identical chart is shown in sect. 13.0.
4. Select desired thread using thread pitch levers (J2, Figure 10-4), referring to charts on end cover. 5. Set feed direction lever (P, Figure 10-5) to correct position (neutral). 6. Engage half nut (N, Figure 10-5). The half nut lever (N) and threading dial (R) are used to thread in the conventional manner, based upon the leadscrew, which is in Imperial units (8 TPI). The thread dial chart (Figure 10-6) specifies at which points a thread can be entered using the threading dial.
1. To adjust drag, loosen rear gib screw one turn, and tighten front gib screw a quarter turn. Rotate handwheel to check play. If still loose, tighten front gib screw a bit more. 2. Repeat as needed until slide moves freely without play. 3. When cross slide is properly adjusted, snug rear gib screw. Do not overtighten; this will cause premature wear on gib and mating parts. Figure 11-4 11.4 Gap section To remove gap section (Figure 11-5): 1. Remove four socket head bolts (J) with hex wrench. 2.
11.5 Aligning tailstock to headstock 6. Firmly tighten hex nut (L). 1. 7. Set fingers snug to workpiece. Fingers should be snug but not overly tight. 8. Loosen three hex nuts (P1), and tighten set screws (P2) to secure finger setting. Headstock and tailstock have been aligned by the manufacturer and should not require attention. If future adjustment should ever be needed, proceed as follows. (Make sure that twist in the lathe bed is not contributing to the problem, refer to sect. 6.3.) 2.
11.10 Gear change Note: The 120/127, 26, and 52 tooth gears are installed by the manufacturer in the end gear compartment. This combination will cover most inch feeds and threads under normal circumstances. The additional gears found in the toolbox are used for some metric threads and feeds. To replace gears: 1. Turn off power at main switch. 2. Remove end cover. 3. Loosen hex nut (S, Figure 11-8) and move quadrant out of the way. 4. Loosen socket head cap screw (T) and remove gear(s).
12.0 Lubrication schedule Regularly scheduled maintenance is crucial to ensure a long service life for your machine. The schedule below shows lubrication points and coolant replacement information for the EVS-1440B Lathe. Push stop button and power off before lubricating. Follow local regulations for disposal of used coolant/lubricants. Minimize direct skin contact with lubricants and coolants, and wear eye protection when pouring coolant in case of splash.
