CNC Lathe Slant Bed Alignment
Materials And Preparation
25mm x 25mm x 1M square steel bar for alignment. Bought from machine shop
800 Bhat ~ $22
Mounted steel bar into 4-jaw scroll chuck & spent much of the day aligning the bed,…several bolt holes needed to be enlarged with Dermal & carbide rotary file.
Bed Alignment Procedure
Bed Alignment Procedure
1. Place into chuck a known straight square or round rod whose length extends to tailstock.
2. Use 2 dial gauges: one gauge reads X axis travel, one gauge reads perpendicular to X axis.
3. Loosen all 10 bolts which fasten bed to frame.
4. Run the Z carriage end to end, taking time to adjust tilt & yaw of the bed to best tolerance.
5. Tighten all 10 bolts starting closest to chuck end, taking care not to move the bed out of alignment during this phase.
6. Loosen all cap screws holding Z rails in place.
7. Using only X axis dial gauge, move rails up or down to achieve +/- 0.001” tolerance of Z motion end to end.
8. Starting at chuck end, Tighten all cap screws while not moving X axis out of tolerance.
Tailstock Assembly
Mounted on a separate set of Linear Rails & bearing blocks.
- Tailstock Rails: 2 DFH15, 1000 MM long and 4 linear bearings, DFH15B.
- One Handle turn = 1mm linear movement.
