Regular maintenance keeps a CNC lathe accurate and extends its service life. Daily checks should cover lubricating oil level, hydraulic pressure, coolant concentration and air pressure, as well as cleaning chips from the ways and tool area. Weekly, inspect the way covers, wipers and spindle taper for wear or damage, and confirm that axis movement is smooth without abnormal noise. Every three to six months, the ball screws, guide rails and tool changer should be measured for backlash, and geometric alignment verified with a level or laser instrument. Electrical cabinets require periodic cleaning and tightening of terminals to prevent heat build-up. Always follow the manufacturer's recommended lubrication schedule and use qualified oil and filters. Keeping a simple maintenance log makes trends visible and helps schedule parts replacement before failures occur.
