Test 1 - Y Axis Ball Screw Axial Test

Anchor
Test-1---Y-Axis-Ball-Screw-Axial-Test Test-1---Y-Axis-Ball-Screw-Axial-Test

...

Move Indicator Side of Carriage. Follow Gib adjustment procedure to get to the .0007 – .001” range. (Accumulative/Stacked Tolerance is factored in here - assuming .0005” per previous two steps.)

...

Test 4 - X Axial Ball Screw Measurement

Anchor
Test-4---X-Axial-Ball-Screw-Measurement Test-4---X-Axial-Ball-Screw-Measurement

Dial Travel Indicator with Mag Base on Lower Machine Base/Chip Tray, and indicator on front side of ball screw. Shake table/ball screw from front to back.

Push and Pull. If test exceeds .001” - you could have an excessive amount of play that could be coming from the ball nut or carriage. (Depending on how worn your ball screw is or how close you are to .001 - you could comp this if it is consistent.)

...

Test 5 - X Axial Table Measurement

Anchor
Test-5---X-Axial-Table-Measurement Test-5---X-Axial-Table-Measurement

Dial Travel indicator to right edge of table. No Motion or Motion Exceeding .0003” – ACB Adjustment Needed (See Angular Contact Bearing Adjustment Procedure then proceed to Test 6.)

...

Test 6 - Radial X Axis Table Measurement

Anchor
Test-6---Radial-X-Axis-Table-Measurement Test-6---Radial-X-Axis-Table-Measurement

Move Indicator with Mag Base on Rail and indicator on the front of the table, one inch in from casting edge. Follow Gib adjustment procedure to get to the .0007 – .001” range. (Accumulative/Stacked Tolerance is factored in here - assuming .0005” per previous two steps.)

...

Test 7 - Z Axis Ball Screw Axial Test

Anchor
Test-7---Z-Axis-Ball-Screw-Axial-Test Test-7---Z-Axis-Ball-Screw-Axial-Test

Dial Travel Indicator on end of ball screw. Shake spindle head rail up and down.

...

If motion is at .0003, proceed to Test 8.

...

Test 8 - Z Axis Casting Axial Test

Anchor
Test-8---Z-Axis-Casting-Axial-Test Test-8---Z-Axis-Casting-Axial-Test

Move Dial Travel Indicator to bottom of Z axis saddle casting. Push and Pull up and down. If test exceeds .001” - you could have an excessive amount of play that could be coming from the ball nut or carriage. (Depending on how worn your ball screw is or how close you are to .001 - you could comp this if it is consistent.)

...

Test 9 - Radial Play in Z Axis Saddle

Anchor
Test-9---Radial-Play-in-Z-Axis-Saddle Test-9---Radial-Play-in-Z-Axis-Saddle

Move Indicator to spindle head and rock. Follow Gib adjustment procedure to get to the .0007 – .001” range. (Accumulative/Stacked Tolerance is factored in here - assuming .0005” per previous two steps.)
