Frequently Asked Questions (FAQs)
1. How effective are parting tools?
Parting tools are highly effective in cleaning up the ends of spindles on the lathe. They help achieve square ends, balance the spindle, and ensure smooth cuts. Using a parting tool also helps prevent sharp or unexpected edges that could pose a risk to fingers during turning.
2. Should parting tool be above or below center?
When performing a parting cut, the top of the parting tool should be exactly on the center line of the lathe or no more than 0.005 inches above the center line. Being slightly above or below center can cause issues, such as the tool climbing or digging into the workpiece.
3. What material is used for parting off tools?
There are two common materials used for parting off tools: high-speed steel (HSS) and tungsten carbide. HSS is cheaper, tougher, and can be reground by hand if damaged. Tungsten carbide can withstand higher heat but requires replacement of the insert if damaged.
4. What angle do you sharpen a parting tool?
A parting tool should be sharpened to have a total bevel angle of 45-80 degrees at the tip. This angle ensures the tool performs effectively during the parting operation.
