Adjusting Cross-slide Backlash
- Loosen the two outer screws using a 3mm hex wrench.
- Loosen the middle screw using a 2.5mm hex wrench.
- Tighten the middle screw until it is just snug.
- Tighten the two outer screws until just snug.
What is backlash on a lathe?
Backlash occurs when one or more moving parts within a mechanism is not engaged with a sufficiently tight fit to the next part of the machine, allowing for some degree of free-movement within the mechanism, which results in lost motion.
How can backlash be overcome?
The simplest and most common way to reduce backlash in a pair of gears is to shorten the distance between their centers. This moves the gears into a tighter mesh with low or even zero clearance between teeth. It eliminates the effect of variations in center distance, tooth dimensions, and bearing eccentricities.
Is backlash good for gears?
Gears and Gearboxes It is the distance between the involutes of the mating gear teeth, as illustrated in Figure 39.17. Backlash is necessary to provide the running clearance needed to prevent binding of the mating gears, which can result in heat generation, noise, abnormal wear, overload, and/or failure of the drive.
What is backlash error?
Backlash error is the error that occurs while we are changing the direction of gears. It can be avoided by turning the gear slowly in the same direction. Backlash error can also be defined as the clearance or lost motion in a mechanism caused by gaps between the parts of the gear.
What is cross feed on lathe?
The cross feed handwheel is used to manually position and/or hand feed the compound rest in the X axis. Carriage Handwheel. The carriage handwheel is used to manually position and/or hand feed the carriage in the longitudinal or Z axis. Carriage. The carriage houses the saddle, the cross slide, and the apron.
