Page 19: Tailstock Positioning
Tailstock Positioning Cross Slide The cross slide moves perpendicular to the longitudinal axis and features a scale on the Longitudinal Positioning handwheel that displays graduations of one To adjust the tailstock longitudinally, do thousandths of an inch (0.002") or 0.05mm. these steps: 1. -
Page 20: Compound Slide
control is necessary when setting up the Compound Slide machine for turning or when manual movement is desired during turning operations. Similar to the cross slide, the compound slide features a scale that displays graduations of one thousandths of an inch (0.002") or 0.05mm. Unlike the cross slide, the compound slide can be rotated to a set angle and then it can be moved... -
Page 21: Carriage/Cross Feed Lever
Understanding Gear Charts The Lathe can be geared for a variety of different feed rates, so charts are placed on the drive cover of the lathe that explain how to set up the gear combinations for each type of carriage feed application. Three applications are broken into two categories of charts-turning and threading. -
Page 22: Threads And Change Gears
Here is a real-world example of a gear setup as shown on the chart: When the lathe is shipped from the factory, it is geared for a carriage feed rate of 0.1mm per spindle revolution, or the gear combination shaded in Figure 24. -
Page 23: Clutch Overload
Reverse threading The lathe can be setup to turn left-handed threads. See Figure 26/ Figure 27/ Figure 28 Figure 28 Fixed screw hole When Forward gear mesh D gear is right- handed threads, see Figure 26 When Reverse gear mesh D gear is left-handed threads, see Figure 27 Figure 26 Forward threading... -
Page 24: Section 6: Maintenance
SECTION 5: MAINTENANCE Lubrication Your lathe has numerous moving metal-to- metal contacts that require proper lubrication to help ensure efficient and long-lasting operation. Other than the lubrication points covered in this section, all other bearings are internally lubricated and sealed at the factory. Simply leave them alone unless they need to be replaced. -
Page 25: Gibs
Gibs There are three gib adjustments for the Model C8—the cross-slide gib, the compound slide gib, and the saddle gib. Cross-slide Gib—The gib on the cross-slide is adjusted by tightening or loosening the five gib screws located on the right-hand side of the slide (shown in Figure 33). -
Page 26: Bearing Preload
Bearing Preload This lathe is shipped from the factory with the spindle bearing preload properly adjusted. If the spindle ever develops excessive end-play and the workpiece finish suffers, you can adjust the bearing preload to remove the unnecessary end-play and improve the workpiece finish. To adjust the spindle bearing preload: 1. - Page 27 the bearing preload adjustment procedure. When repeating the procedure, rotate the inner spanner nut a little less during Step 7 in the preceding instructions. NOTICE Do not over tighten the outer spanner nut because additional pressure can force the bearings even tighter against the races in the headstock and cause the headstock to compress, crack, or...
