Essential Pre-Commissioning Steps for Slant Bed CNC Lathes
Manufacturers widely use slant-bed CNC lathes to machine high-precision, high-surface-quality parts, including counter-rotating components. Proper pre-commissioning steps ensure these machines operate at full potential. The guide below details the essential processes you need to complete before putting the machine into full operation.
I. Installation and Leveling
Proper installation and leveling are fundamental for the accurate operation of slant bed CNC lathes. Begin by leveling the machine on its foundation. This should be done while the machine is in a free state, followed by evenly tightening the anchor bolts. For conventional machine tools, the spirit level reading should not exceed 0.04/1000 mm. However, for high-precision CNC machines, this must not exceed 0.02/1000 mm. Measurements should be taken at stable temperatures, and instruments should be acclimated for accurate readings. Avoid installation methods that could cause forced deformation, as this can impact the machine’s accuracy.
II. Cleaning and Lubrication
1. Post-Inspection Cleaning: Once the machine has passed the geometric accuracy inspection, thoroughly clean all parts of the machine. Use a cotton or silk cloth soaked in cleaning agents—avoid using cotton yarn or gauze. Remove rust-preventive oils and paint applied to the guideways and machined surfaces. Clean any dust from the machine surface and apply the specified lubricant to all sliding and working surfaces.
2. Lubrication System Check: Check all required lubrication points on the CNC lathe to ensure proper oiling. Confirm that the coolant reservoir has the correct level of coolant. Also, verify that the oil level in the hydraulic station and the drive lubrication system are within the recommended levels.
III. Electrical System Inspection
Ensure that all switches and components within the electrical control cabinet are working correctly. Technicians double-check that all plug-in integrated circuit boards are installed correctly to prevent electrical malfunctions, ensuring smooth operation when the machine powers up.
IV. Centralized Lubrication System Activation
Activate the centralized lubrication system to fill all lubrication points and oil passages with the specified lubricating oil. Completing this step ensures that all parts receive proper lubrication before any machine components are operated.
