V shape threading on lathe • • • V-shape threading on a lathe involves cutting threads with a V-shaped profile, typically for screws or bolts. This process requires setting up the lathe properly and using specific tools and techniques to achieve accurate and clean threads. Here's a general guide on how to perform V-shape threading on a lathe: • Steps for V-Shape Threading: • 1. Select the Threading Tool: Use a 60° V-thread tool for standard metric or imperial threads. Ensure that the tool is sharp and properly ground. • • 2. Set the Lathe Speed: For threading, a lower spindle speed is typically used to maintain control, often around 100-200 RPM depending on the material and thread size. • • 3. Mount the Workpiece: Secure the workpiece in the chuck and ensure it is centered. The workpiece should be long enough to allow clearance for threading. • • 4. Set the Tool Post: The threading tool should be mounted in the tool holder and positioned perpendicular to the workpiece. Use a thread gauge to check the angle and alignment of the tool with the workpiece. • • 5. Engage the Threading Dial: Set up the lathe's thread cutting mechanism by engaging the leadscrew and selecting the correct pitch for the desired threads. • • 6. Depth of Cut: Start with a light cut (typically 0.05-0.1 mm or less). Gradually increase the depth with each pass, but avoid taking too heavy cuts to prevent tool damage or poor thread quality. • • 7. Cut the Thread: Use the lathe's carriage feed to move the tool along the workpiece. Make successive passes, incrementally deepening the cut, until the desired thread depth is achieved. • • 8. Check the Thread: After a few passes, use a thread gauge or mating part to check the fit of the thread. Make fine adjustments if necessary. • • 9. Final Pass: Make a final finishing pass with minimal material removal to ensure smooth and accurate threads. • • 10. Deburr and Clean: After threading is complete, use a file or deburring tool to clean up any sharp edges or burrs on the workpiece. • • This process can be adapted based on the specific threading specifications and materials being used. • • • • #india #karnataka #davanagere #automobile #latheturning #machine #amazing #tools #lathe #threadcutting #lathemachine #workshop #instagram #instagramreelsoftiktokstars #youtube #youtubeshorts #reels #shorts • • • :RS Engineering Works: • • Channel Description: • Welcome to RS Engineering Works!
