Why should small chips be cleaned off the spindle nose of a lathe?

• A. To prevent rust formation
• B. To avoid run out on work holding devices
• C. To ensure proper lubrication
• D. To maintain a clean working area

Answer: (B)

Cleaning small chips off the spindle nose of a lathe is essential to avoid run out on work holding devices. When chips accumulate on the spindle nose, they can create an uneven surface, leading to improper clamping of workpieces. This can result in vibrations and inaccuracies during machining, severely affecting the precision of the work being performed. Ensuring that the spindle nose is clean allows for proper seating of the work holding devices, which helps maintain alignment and stability during operations, ultimately contributing to better quality workmanship. While preventing rust formation, ensuring proper lubrication, and maintaining a clean working area are all relevant considerations in a machining environment, they do not directly address the specific issue of work holding accuracy, which is the primary concern when it comes to the condition of the spindle nose.
