Question 1 of 27070

If you are machining work held between lathe centers, and the lathe centers begin to squeal, you should first __________.

🔍 Key Concepts

• How work is supported between centers on a lathe • The purpose of lathe centers and what causes them to squeal • Basic safety vs. maintenance priorities when a problem suddenly develops

💭 Think About

• What does a squealing sound at the centers usually indicate about friction or lubrication? • Among the options, which action most directly addresses the likely cause of the squeal, rather than just changing operating conditions? • Which choice would you reasonably do first while the work is held safely and correctly between centers?

✅ Before You Answer

• Identify whether squealing is more likely caused by speed, tool wear, or lack of lubrication/too much friction at the centers • Consider what routine practice machinists use to keep centers from overheating or galling • Ask: which option would a skilled machinist treat as the normal first response to centers starting to squeal, before making any other adjustments?
