Bench grinders can easily handle just about any tool sharpening job you have How to use a bench grinder to sharpen tools: One of the key steps you need to take is to keep safety first.

Match the wheel to the metal being sharpened - it is the right tool for the job rule that always applies. For old tools, you may want to go with a 60 grit aluminum oxide wheel and medium hardness.

Put the tools in your oven - not too hot just set your oven to degrees and let the tools sit inside for 2 hours. This treatment will help prevent cracking when being sharpened. Use the edge of the grinding wheel to make short work of the mushroom look, then start on the tip. Take your time and do several passes. You need to be careful of any red hot pieces of metal that will come off as you grind away.

Make sure you keep dipping it in cool water, oil or some other cool lubricant. Overheating the tool only works against you. Finally, use a wire brush - this will remove any rust that is on your old tools. V tool rests. This is due to the purpose of each tool. The following instructions are for the diamond parting tool. I mentioned pocket knives earlier and nothing puts a better edge on a knife blade than the original Lansky Sharpening System.

They use a guide, clamped to the blade, that prevents accidently stoning the edge, even briefly, at the wrong angle. Each stone has a long rod extending from the back that rides in the guide. The same principle can be applied to almost any edge you want to touch up, including end mills and dovetail cutters.

You can make up your own stones by glueing them to a bar, or using lapping film this is where the PSA is useful , but I just use the Lansky stones right from the standard set. Here's the basic idea for touching up an end mill, though one would want things tied down a bit better than sitting on the studio seamless. Yes, I know this is about lathe tools; use some imagination and apply the technique to whatever edge you need to deal with. The methods above will suffice for almost all typical turning needs using HSS and cast alloy tool blanks.

The angles can be held to sufficient accuracy by eye and experience. This is not the case for threading. As a bare minimum you should use a "fishtail" gage to check the included angle and squareness of the tool, but that still leaves you a long ways from what can be achieved with very little additional effort. Once you've roughed out the tool on the grinder, you need a fixture to perfect the angles.

I made the fixture shown here from a scrap cutoff of Delrin. I had made a rectangular one some time back but it grew legs, so they must be desirable. The exact shape and dimensions aren't important, though you should try to keep the two feet and the tool tip near the points of an equalateral triangle. The fixture is a kinematic design; it has three contact points making it completely stable in use. The angles can be changed slightly, but you'd need a different fixture for Acme or other threads with significantly different angles.

You can make a nice angle template out of aluminum roofing flashing. Just scribe it and cut it on a paper cutter not a rotary cutter. If you want to work from a different side of the tool, or the fixture itself, the template can certainly be cut to reflect that preference. Next we go to the back of the tool to set the relief angle. It will be necessary to go back and forth a couple times because the adjustments interact.

If you look closely you can see the perfect facet at the tip created by the ultra-fine black Arkansas stone. The nearby edge of the tool catches the light, but it's still rough ground and didn't hit the stone. You can also use the fixture on glass or a surface plate with lapping film. This is pressure sensitive aluminum oxide film, and the adhesive backing rounds the facet slightly, resulting in a slightly less sharp and less free cutting tip.

Try to get plain lapping film. Now, flip the tool over in the fixture, readjust, and tune up the other side. You may want to remove excess material that doesn't need to be lapped as described shortly, so the lapping operation goes swiftly. With a properly ground tool, lapping shouldn't be any more than a ten minute job. OK, tell me again why we need this level of control over the edges?

For a thread to function properly, the flanks of the screw need to contact the flanks of the nut. If the angles are off, the contact area will be a narrow high pressure line near the ID or OD of the thread. The lubricant won't be able to support the pressure and you'll get metal to metal contact, possibly galling and certainly higher friction than would otherwise be the case.

If you're making an adjustment screw for a laser mirror mount, it certainly does matter. For conventional HSS lathe tools the hollow grinding technique described above works well.

For threading tools that get lapped using a fixture you can save a huge amount of work by removing unnecessary material at the grinding wheel. You should be lapping the minimum amount of material necessary to the function of the tool. If it only takes. If the maximum thread depth you ever cut is. This is even more of a time saver with carbide. Carbide is a wonderful thing for many jobs.

Very little HSS is used commercially anymore. You'll hear that carbide isn't as suitable for the home shop as HSS, but I don't fully subscribe to that view. The problem is that commercial carbide inserts are designed for production use on completely different machines than most HSMs own.

They're typically not very sharp, may have negative rake and may have coatings that only function at high cutting rates that produce high temperatures. There exist sharp uncoated inserts for aluminum, and these should be fine even on a small light machine as is usually found in the home shop.

In general I find inserts are an expensive and unnecessary complication for the HSM. Brazed carbide tooling ranges from poorly made imports, to the very fine Micro tooling. Other than those high end tools, few brazed tools perform their best right out of the box, and you can't fix this using only a green carbide wheel.

More likely you'll make things worse. If you want carbide to perform like HSS, you have to create sharp edges like HSS, and that requires diamond abrasives. For threading tools, follow the procedures above, but use a green wheel followed by diamond lapping films. Easy, problem solved. For other lathe tools the best solution is a slow speed diamond wheel grinder like the Accu-Finish, or a diy version of the same thing. Lacking that, the diamond lapping films will get you where you want to go, slowly, but once you've used a purpose-built carbide grinder with a proper adjustable sliding table and diamond wheels, you'll be too spoiled to consider anything else.

I might add that, lest you think I'm over the deep end, the Accu-Finish people provide a smooth ceramic grinding disk, plus a bottle of fine diamond fluid to charge it. The unit comes with a sharpening piece, angle guide, and the polishing paste.
