Spindle Backlash on Bridgeport J-Head

Jul 06, 2011The spindle on my J-head has backlash of a few degrees. When milling an edge, it leaves chatter that looks like a edge of a coin or a washboard. My question is Where is it most likely for this to occur? If I hold the drive belt and reach down and rotate or oscillate the spindle in each direction

How to Analyze Gear Failures machinerylubrication

Gear tooth surface wear involves removal or displacement of material due to mechanical, chemical or electrical action. The three major types of wear are adhesion, abrasion and polishing. Adhesion is the transfer of material from the surface of one tooth to that of another due to welding and tearing (Figure 5). It is confined to oxide layers on

Surface grinder vertical backlash a problem?

Mar 15, 2017When I have worked with it before in the past, I'm pretty sure that the grinder's vertical axis had zero backlash. I assumed that this was because the weight of the spindle and motor assembly kept the lead screw nut sitting on the top of the lead screw thread, just like with the Z-axis of a mill.

Study on coupling effect between the time-varying gear

The vibration excitation of the rolling mill mainly comes from the gearbox in the process of rolling strip, and the meshing excitation is the main excitation factor of the gearbox. And the gear backlash plays an important role in the meshing excitation. However, the backlash is inevitable in the process of designing the gear system. Therefore, it is important to select the appropriate gear
