Mastering the Art of Machining: A Step-by-Step Guide

Machining with a vice and swivel base requires precision and attention to detail. This article provides a comprehensive guide on how to use a vice with a swivel base for accurate and efficient machining.

Setting Up the Workpiece

⚙️The machining will be done in two setups.

⚙️Use the back face of the casting as a reference surface to position the workpiece.

⚙️Ensure all jaws are touching and snug up the workpiece using copper pads.

⚙️Tighten the lows and loosen the highs to ensure the jaws are snug.

⚙️Using an indicator to ensure center alignment.

Machining Techniques and Tips

🔧Roughing inserts like the Walter WPP 30G are suitable for taking roughing passes on cast iron.

🔧The surface finish looks good and the speaker decides to take another 10,000 to clean up minor spots.

🔧The final bore size achieved is 1.343 inches.

FAQ

What is the importance of using a swivel base for machining?

A swivel base allows the vice to rotate in any position, providing flexibility and ease of access to different angles for machining.

How can I ensure proper alignment of the workpiece in the vice?

Tighten and loosen jaws to ensure proper alignment, and use an indicator to ensure center alignment.

What type of inserts are suitable for roughing passes on cast iron?

Roughing inserts like the Walter WPP 30G are suitable for taking roughing passes on cast iron.

What is the recommended technique for achieving a clean surface finish?

The speaker decides to take another 10,000 to clean up minor spots and achieves a good surface finish.

What is the final bore size achieved after machining the swivel bolt?

The final bore size achieved is 1.343 inches.
