The metal lathe parting tool is one of the most important tools in the lathe. It is used to separate pieces of metal from each other. The parting tool must be sharpened regularly to ensure that it can do its job properly.
There are a few different ways to sharpen a metal lathe parting tool. One way is to use a bench grinder. Another way is to use a file.
A third way is to use a sharpening stone. All of these methods will work, but the best method will depend on the type of tool and the condition of the tool.

How to Make a Metal Lathe Parting Tool
A metal lathe is a powerful tool that can be used to create parts for a wide variety of applications. In order to make full use of its capabilities, it is important to understand how to properly use all of the different types of tools available for it. One such tool is the parting tool, which can be used to create clean cuts in metal stock.
When using a parting tool, it is important to keep a few things in mind in order to get the best results. First, the cutting edge of the parting tool should be perpendicular to the workpiece at all times. This will ensure that the cut is clean and accurate.
Second, the feed rate should be slow and steady in order to avoid chatter marks on the finished part. Finally, it is often helpful to use a coolant when cutting with a parting tool as this will help prevent heat build-up and improve cutting quality.
With these tips in mind, let’s take a look at how to properly use a parting tool:
1) Start by mounting the workpiece on the lathe spindle and securing it in place with chucks or clamps.
2) Adjust the carriage so that the cutting edge of the parting tool is positioned where you want the cut to start.
3) Engage the lathe spindle and slowly bring up its speed until it reaches its recommended revolutions per minute (RPM).
For most materials, around 600 RPM will suffice. Higher speeds may be necessary for harder metals though. 4) Begin feeding the carriage towardsthe headstock while keeping an eye on boththe depth of cutandthe angleof attack(how closeto perpendicularthe cuttingedgeis tobethe workpiece surface).

How Do You Sharpen a Parting Tool for a Lathe?
As with most tools, there is some debate on the best way to sharpen a parting tool. The general consensus seems to be that the best way to sharpen a parting tool is by using a diamond sharpener.
There are three main ways to use a diamond sharpener: by hand, with a power drill, or with a bench grinder.
Each method has its own set of pros and cons.
By hand: This method is the most basic, and probably the most difficult. It requires you to hold the tool at just the right angle against the diamond sharpener in order to get a good edge.
However, it is possible to get a very sharp edge this way if you are careful and have patience.
With a power drill: This method is faster than sharpening by hand, but it can be more difficult to control the angle of the tool against the diamond sharpener. It is important to practice first before trying this method on an actual project.
With a bench grinder: This method is fastest of all, but it can be easy to overheat and damage the cutting edge of your parting tool if you’re not careful.
What Angle Do You Grind a Parting Tool?
There are a few schools of thought when it comes to the angle you should grind your parting tool. Some people recommend grinding at a bevel angle between 30 and 45 degrees, while others recommend using a shallower angle between 10 and 30 degrees.
Personally, I think the best angle to grind your parting tool depends on what material you’re working with.
If you’re working with softer materials like wood or plastics, then a shallower angle will work just fine. However, if you’re working with harder materials like metals, then you’ll want to use a steeper angle so that your tool can bite into the material better.
Ultimately, it’s up to you to experiment and see what works best for you.
Different angles will produce different results, so it’s important to find what works best for the material you’re working with and the results you want to achieve.
How Do You Sharpen a Robert Sorby Parting Tool?
If you’re looking to sharpen your Robert Sorby parting tool, you’ll want to follow these steps:
1. First, you’ll need to secure the tool in a vice. Make sure that the cutting edge is facing up and that the point of the tool is level with the top of the vice.
2. Next, take a sharpening stone and hold it at approximately a 25 degree angle to the side of the blade. Begin running the stone along the length of the blade, applying light pressure as you go.
3. Continue until you’ve sharpened the entire length of the blade.
Then, turn over your sharpening stone and repeat on the other side of the blade.
4. Once both sides are complete, remove your parting tool from the vice and test it out on some scrap wood to make sure that it’s sufficiently sharpened.
How Do You Use a Parting Tool on a Metal Lathe?
When using a parting tool on a metal lathe, it is important to first mark the depth of cut that is desired. The cutting depth should be no more than 1/3 of the total diameter of the workpiece. Once the desired depth is marked, the parting tool can be set to that height and locked in place.
The next step is to adjust the speed of the lathe. For most metals, a slower speed will produce a cleaner cut. The feed rate should also be slow, as too much pressure can cause the tool to chatter and produce an uneven surface.
Once everything is in place, the lathe can be started and brought up to speed. The cutting edge of the parting tool should then be slowly introduced to the workpiece until it reaches the desired depth of cut. After that, it’s simply a matter of letting the machine do its work until the cut is complete.
Conclusion
If you’re looking to sharpen a metal lathe parting tool, there are a few things you’ll need to do. First, you’ll need to get yourself a sharpening stone. You can find these at most hardware stores.
Second, you’ll need to clamp the tool in a vise so that it’s secure while you’re sharpening it. Third, using your sharpening stone, start by honing the cutting edge of the tool. Once that’s done, move on to polishing the blade with some fine grit sandpaper.
Finally, put the finishing touches on your newly sharpened tool by buffing it with a piece of leather.
