2. Applications
Thread turning Thread milling
Thread turning
• Normally the most productive threading method
• Covers the largest number of thread profi les
• An easy and well known threading process
• Provides a better surface fi nish
• Can be used in deep holes with dampened bars
• Has dedicated thread programs in CNC machines
Thread milling
• Threading of non-rotating components
• Interrupted cuts offer good chip control in long-chipping materials
• Lower cutting forces make it possible to thread in long overhangs and thin-walled
components
• Threads close to a shoulder or bottom, no need for a relief groove
• Enables machining of large workpieces which cannot be easily mounted on a lathe
Thread milling vs. thread turning
This application guide focuses on thread turning and thread milling
products and application techniques. Each technique has its own
advantages in certain situations.
