Here is a picture of what I am trying to do. http://imgur.com/NfLfYYY Fluid is going along the two channels in the middle. The bottom part is moving back and forth. I'm using a Polyurethane ring so I'm not too worried about shearing when it crosses that small hole I just need to make sure it seals properly when the two channels are aligned. Also pressure differential the o-ring is sealing against is close to zero (mainly being used to direct flow).

Don’t tighten the top nut with an extender bar or pipe on a wrench. Always use a torque wrench to ensure that you tighten the nut to the correct setting. Different tool holders, collets and nuts have different torque settings, so check your catalogs and manuals to ensure you get this right. If you over tighten the top nut you can break the collet, the nut or even the tool holder.

It’s very important to ensure that the tool is securely and evenly seated in the collet before tightening it and locking it in. The collet must securely clamp the tool before the wrench is used to lock it. If the tool is locked when the collet is not evenly clamped to the tool the collet will deform and be damaged when you lock the tool.

Don’t try to fit a cutting tool with a flatted shank into a collet chuck. Flatted shank tools are designed to fit into side lock end mill holders. Collet chucks are designed to apply even pressure to a round tool shank. This ensures perfect center alignment of the tool for high precision. If you fit a flatted shank tool it will not center correctly leading to poor precision, rough cutting or breakages.

They are used to hold a tool in a central position as it rotates. Collets are tapered to apply a very even and strong clamping force on the tool when they are tightened. This centers the tool very accurately, which is ideal for precision cutting.

Collets can only expand a small amount, so you need different sized collets if you have multiple tool shank sizes. This adds to the cost of tools, so they are usually used for precision work and not in hand drills or other small machines where accuracy is less important.

Collet chucks are lighter than CNC lathe chucks, which means they have lower rotational inertia. This means they can be started and stopped more rapidly than heavier chucks and require less power to spin at high speeds, making them ideal for high speed cutting and machining uses.

The Chain Headway BR Milling Inserts are the ideal choice for addressing surface polishing and contouring needs in the production of large ship anchor hooks.”

Don’t insert cutting edges of tools into the collet. It is very important not to put the tool so far inside the collet that the collet clamps on the cutting edge. This causes problems with alignment accuracy and damage to the collet for two reasons:

Collet chucks can be damaged by incorrect setting and tightening. When you are mounting a tool in your collet chuck there are three common mistakes that cause damage or inaccurate cutting when using a collet chuck. Here are three simple rules that will keep you from making these mistakes.

Any help would be greatly appreciated otherwise I will have to try guessing and checking until I get something that works.

Collets are the best choice for clamping tools for precision machining. They have four specific features that make them different from standard chucks.

Hi guys does anyone have experience designing dovetail grooves for small o-rings? The guides I have found online don't seem to give recommendations bellow -004. I am using a -001 ring.

A collet is a cylindrical sleeve used to make a collar around a cutting tool that can be squeezed onto the tool to hold it in position. Collets are usually manufactured from spring steel. When you insert a tool into the collet, the collet expands uniformly to hold the tool very securely in place.
