SNS 322 Machining Rucker Straight Edge
Abom79・2 minutes read
The machining process involves using various mills to achieve specific measurements, including a three-inch Tungaloy face mill. The final step includes using a shaper to cut a 45-degree angle to match the bottom edge for a scraped surface finish.
Insights
- The machining process involves a detailed sequence of steps on the K&T mill, starting with the sides, moving to the back side, and finishing with the bottom, utilizing specific tools like end mills and face mills to achieve precise measurements and finishes.
- Additional modifications, such as adjusting the thickness using a Tungaloy face mill, addressing casting issues by adding material, and utilizing a shaper to cut angles for a scraped surface finish, demonstrate the complexity and attention to detail required in achieving the desired results in machining projects.

Recent questions
How is the machining process on the K&T mill described?
The process involves machining two pieces on the K&T mill, starting with the sides, then the back side with an end mill, and finishing by cutting the bottom with a face mill. Measurements are taken before machining, aiming to leave the piece at 9 and 1/8 inches, with approximately 45 thousandths to be removed.
What tools are used in the machining process?
The machining process involves using a three-inch Tungaloy face mill to achieve a thickness of three-quarters of an inch, taking around a hundred thousandths off. A shaper is also used to cut the angle at 45 degrees to match the bottom edge, ensuring a scraped surface finish.
What is the finishing pass speed during machining?
The finish pass is done at 22 inches per minute and 438 rpm during the machining process on the K&T mill.
How is the angle on the front side of the piece machined?
The next step after completing the first piece involves machining the angle on the front side by taking a quarter inch off the bottom to meet the angular side, with additional material added to address previous casting issues.
What is the final step in the machining process?
The final step involves using a shaper to cut the angle at 45 degrees to match the bottom edge, ensuring a scraped surface finish on the machined pieces.

Machining process for precise angle cuts
- The process involves machining two pieces on the K&T mill, starting with the sides, then the back side with an end mill, and finishing by cutting the bottom with a face mill.
- Measurements are taken before machining, aiming to leave the piece at 9 and 1/8 inches, with approximately 45 thousandths to be removed.
- The machining process involves using a three-inch Tungaloy face mill to achieve a thickness of three-quarters of an inch, taking around a hundred thousandths off.
- The first piece is completed with a good finish, and the next step involves machining the angle on the front side.
- A quarter inch is usually taken off the bottom of the piece to meet the angular side, with additional material added to address previous casting issues.
- The second piece is machined similarly, with a finish pass done at 22 inches per minute and 438 rpm.
- The final step involves using a shaper to cut the angle, set at 45 degrees, to match the bottom edge, ensuring a scraped surface finish.
