I fiddled with this for a while, and on the last run through, I failed to get the card latched all the way in the slot. I hit the eject button to order the faceplate to swing back up - and it did, but when I tried to get the card back out, the card kept the faceplate from opening all the way. It was stuck partially open. We stock a large inventory of high quality studs and t-slot clamp kits for bench top machinists. 5035 Clamping Kit for C8 Faceplate: $ Clamping Kit for.

Lathe – workholding – faceplate

If turning between centers is the oldest form of turning then turning using a faceplate must be the second oldest.Often, in old pictures of big lathes, the lathe has just a faceplate.

Though the faceplate is a very simple idea, it can, sometimes with some difficulty, be made to do a very wide range of jobs.

Key features of the faceplate

Assuming the face plate is fitted securely to the spindle there are three key features that it needs. Firstly it is round and, secondly, it has a flat surface. It should be obvious that both of this can be produced simply by turning the faceplate when fitted to the spindle. Thirdly it needs some method of fixing a workpiece or workholding device onto it.

On old faceplates the faceplate was cast roughly to the required shape but with holes or slots in it. The workpiece could then be bolted onto the face plate. Modern faceplates are often fitted with T-slots in them.

Holding a workpiece onto a faceplate

In all of the following methods of holding a workpiece on a faceplate there is one common factor. It is often easier to fit the workpiece when the faceplate is lying, horizontal, on the bench rather than is vertical on the lathe.

It is often not possible to fit the workpiece completely but it is usually possible to fit the workpiece sufficiently so that when the faceplate is fitted to the lathe there is no risk of the workpiece falling onto the bed of the lathe.

Often workpieces fitted to a faceplate might not be balanced. In some cases it might not be possible to balance it. Change gears for the lathe can sometimes be used as counterweights. However most workpieces can be turned safely if the speed of rotation is slow enough.

Holding the workpiece using clamps

The workpiece can be held onto the faceplate by using the same sort of clamps as might be used on a milling machine. However the T-slots on the faceplate are often distinctly smaller than those on a milling machine of a similar size to the lathe being used. A further limitation is that whereas a workpiece on a milling table can hang over the edge, on a faceplate the workpiece is limited by the bed of the lathe.

The real problem is that the T-slots are often at right angles to each other. When using these it is seldom possible to place the clamping bolts where they are best used.

One solution to this is to fit an auxiliary plate to the faceplate. This plate is fitted with a rectangular array of threaded holes which can take the clamping bolts.

(Yes – this is the same plate as is used elsewhere on a rotary table – and for exactly the same reason.)

Holding the workpiece using an angle plate

Many angle plates have slots going one way on one side and going the other way on the other side. If, for example the T-slot on the face plate is horizontal then the slot on the angle plate touchinf the faceplate should be vertical. This means the angle plate can be easily moved horizontally or vertically.

The space on the faceplate is maximised by using an angle plate where the inside is also machined flat. The workpiece is fitted “inside” the angle plate.
