A much nicer solution grinding lathe tools youtube 02 an adjustable-height tool holder. This is an attempt to try and explain in simple terms the tool design, terminology and the grinding process needed to create it. The completed tool. Mine sits in its box for years at a time. That is truing the hard jaws on a universal chuck while it is installed on its own lathe. If you look at the cutting action of the typical lathe tool, you'll see that the actual cutting takes place along a line, and usually a very short one at that.

The gouges were way too hard for the white stones and were wearing the stones and forming grooves in the stones. These pink stones 60 grit Grinding Lathe Tools Youtube 04 and grit are doing MUCH better and I am not having the problems that were occurring with the white stones.

While this takes time it is well worth it when you hit the "sweet spot" and the vibration is gone! The plastic arbor inserts are a joke. If you need to use an insert, you have wasted your money since the inserts make the wheel wobble and not turn true.

It's like trying to ride a bike with a bent wheel or sharpen a lathe tool with an off-set or eccentric chuck. It just isn't going to happen smoothly. Quite disappointed. Find a Store. My Account.

The tip of the tool blank should be a little below the center line of the wheel.

Remember to use a wheel-dressing tool from time to time to freshen up the surface of the grinder wheels. Doing so will make the job of tool grinding go more quickly and with a better result.

Grinding causes the tool blank to get quite hot so you will need to dip the end of the tool into a water bath every 15 seconds or so during the grinding operation. When you see the tip of the tool start to discolor from the heat its a good time to make a cooling dip. Fortunately, HSS does not conduct the heat to your fingers very fast, but you can get burned if you go too long between cooling dips. My water cup was cut from the end of a plastic bottle. Now we'll grind the left side of the tool.

The procedure is essentially the same except that we hold the tool with the side at about a 10 degree angle to the grinding wheel. Now we grind the top surface to form the rake.

Be careful during this operation not to grind down the cutting edge or you will end up with a tool whose tip is below the center line of the lathe. If this happens, the tool will Grinding Lathe Tools Youtube On Mac leave a little nub at the center of the workpiece when you make a facing cut. The usual remedy is to use a thin piece of shim stock or feeler gages under the tool to bring it back up to the center line.

A much nicer solution is an adjustable-height tool holder. After this operation we have a working tool with a very sharp tip. This tool is useful as-is for operations that need a sharp tip to turn down to an interior edge such as a shoulder.

We will round the tip to form a tool that is useful for facing and turning. Hold the tool so the tip touches the wheel and with the tool tilted downward. Here's the finished tool in action making a finishing cut on a facing operation:. As a final step, you may wish to smooth the cutting tip on a fine diamond hone or oilstone. I've found that the tip tends to get smoothed pretty quickly after a few cuts, so I usually skip this step, but it does make a difference if you need a fine finish.

So now you know how to grind the most basic of cutting tools. There are many other types of tools that you can grind including shaping tools, cutoff tools and boring tools. Here's some additional info posted by Brian Pitt:. A greater rake angle reduces cutting forces and gives a better tool life, but too much rake can make the tool fragile.

The diagram below shows the terminology used to describe cutting tools click for a larger image. Different materials are best cut using slightly different angles and the table below gives some suggested angles for the critical faces; but in summary harder materials have a smaller rake Grinding Lathe Tools Youtube Videos angles and softer ones greater rake angles. The exception is Brass and bronze which are usually cut with zero or negative rake to prevent 'digging in' of the tool.

A Tool Grinding Rest. Accurate Grinding Lathe Tools Youtube Android grinding of the required faces can more easily be achieved with an adjustable grinding rest. The photo on the right shows a simple grinding rest which is only angle adjustable not height and it has a sliding fence which can be used to hold the cutter at a set angle as it travels across the edge of the grinding wheel.

Some notes on the construction of the grinding rest can be found here. Throughout this sequence the tool temperature was kept reasonable by frequent dipping in a pot of water. Also - always ensure that the safety guards are in place on the grinding wheel, and always wait for it to stop before adjusting the rest. The first face to be cut was the side face. In this example we are making a normal right handed tool for the lathe.

Grinding the side face of the tool. The grinding rest was tipped to give the required side clearance relief and the fence adjusted to give the side cutting edge angle. The work was fed across the edge of the grinding wheel with a light inward pressure to make the cut. The angle set by the table is the important angle here as is sets the side relief. The angle of the fence is non-critical and is simply used so that the side relief doesn't have to be ground all the way along the tool.
