That''s a nice tool to have. Before you go off making others, check the cutting results of this grind on all metal types, you may not need the spread of angles you think, those were optimized for larger machines in a production environment, a mini lathe in the home shop has a much wider range of flexability.
Use a bench grinder to sharpen your tool bits. Even an inexpensive bench grinder can do a good job grinding lathe tool bits. In some cases, you might want to purchase a higher quality fine grit wheel.
Begin by dressing the grinding wheel. Next, look up the typical angles for the workpiece material, and then follow the steps in Figure A2. Dip the tool in coolant frequently to keep it from overheating and annealing. Any discoloration on the bit indicates it may no longer be hardened. If this happens, consider starting over again from the beginning.
#0183;#32;I have never sharpen metal lathe tool bits on Tormek. In my understanding Tormek is not suitable for it. Some edges could be touched from the Tormek Tool Rest, but you will get hollow grinding. To grind a flat surface, you would have to use the outside of
The essence of lathe tool grinding, as I think of it, is to undercut the tip of the tool to provide ''relief'' so that the metal just below the cutting tip does not contact the work. This concentrates enough cutting force on the tip to cut into the metal of the workpiece.
A lathe is a machine that rotates the workpiece about an axis of rotation to perform various operations such as turning, undercutting, knurling, drilling, facing, boring, and cutting, with lathe cutting tools that are applied to the workpiece to create an object with symmetry about that axis.
For normal lathe tools it is easy to set up the rest to have the correct angle and then using the scribed lines as a guide to grind the facets on the tool tip. However, this method is not very satisfactory for grinding threading tools where the angle of the tip must be accurate.
#0183;#32;Lathe tools are some of the most misunderstood and underappreciated tools in the shop. The tip geometry on a HSS tool is hard to visualize, let alone understand, and grinding them accurately is even more confusing. As you grind, the tool will heat up; just dip it in cold water and move on.
Grinding the end face of the tool. The grinding rest was tipped to give the required end relief angle and the fence adjusted to give the front cutting edge angle. Again the front cutting edge angle
To sharpen your metal lathe tools in a safe and effective manner, use the following guidelines that have been presented in an easytounderstand manner.. Step 1Getting Started with Basic Preparations. Get started by wearing proper eye protection. Small fragments of metal are dispersed in the air when using the lathe.

How to Grind Tool Bits Use a bench grinder to sharpen your tool bits. Even an inexpensive bench grinder can do a good job grinding lathe tool bits. In some cases, you might want to purchase a higher quality fine grit wheel. Keep a small cup of water near your grinder. Grinding generates heat, which can cause two problems.

#0183;#32;The idea of sharpening metal lathe cutting tools has been floating around the forum for years, however, your plan is the first working model I have seen. I have long thought that the SVD110 platform can be much more versatile (as can Herman''s HK50).
