Maintenance Tips
-
Keep the lathe bed, carriage, and collet closer clean after each use to prevent chip buildup.
-
Lubricate spindle bearings, leadscrews, and sliding ways routinely to extend service life.
-
Check ACU-RITE 203 DRO accuracy and recalibrate to ensure precise measurements.
-
Inspect collet closer alignment and clamping pressure for reliable workholding.
-
Monitor belts, gears, and electrical systems for wear and proper tension.
-
Tighten gibs and adjust backlash to maintain cutting precision and rigidity.
-
Schedule alignment checks and servicing for consistent long-term performance.
