Custom Tool Solutions for Your Manufacturing Requirements

Customers looking at our custom solutions area ask why there are no descriptions to the pictures.

We do special versions of our products on a continuous basis. Usually they are variations of a concept of our standard offerings or a special mounting of a standard tool.

We cannot show all we have done nor do we show our products being used. Different industries or different areas of the world use our products in unique ways. I have seen many of them but by no means all of them.

We are trying to show concepts and ideas to stimulate your mind and use us to accomplish your unique requirements.

Please ask us about custom solutions.

Many applications can be addressed by taking a standard product and altering it by size, orientation or material. This keeps cost down from a true full custom solution and provides you with a tool that has most of the engineering decisions already proven.

I invite you to call me so we can discuss your specific applications.

How to Maintain Your BTD Style Chuck

Maintaining your 3 or 6 Jaw Precision Stainless Steel Chuck.

BTDSQ12In the past year we have been getting more and more BTDs in that need significant cleaning prior to us figuring out what is wrong with them. The conclusion is:

You have to maintain the chuck better.

The chucks look newly cleaned on the outside when we get them. Do not waste your time doing this. Spend your time maintaining the interior of the chuck. Remember you or your company spend significant money obtaining this tool.

Precision Chuck maintenance tips

BTDRWhen you are done with your job, prior to all the material swarf has dried, you need to do the following.

  • Flush the chuck out with water in closed, middle and open positions.
  • If you have an ultrasonic cleaner use it.
  • Spray WD-40 or equivalent on interior of chuck.
  • Flush chuck again if you do not want WD-40 in your machine environment.
  • If you use any cleaner that you use in your machine on the chuck you need to flush the chuck out excessively.

If a chuck does not have swarf in it many times we see that the cleaner has dried on the chuck internally.

We have chucks in the field since 2003 that are used daily and have never needed rebuilding. Yours could be one of those also with just a little careful maintenance.

Grindit – NBG  NBG

A very all-purpose tool for spinning and indexing.

The unit has 15° internal indexing stops and adjustable stops for off angle locking and arc limiting. Adjustable stops are set by mounting on a sine plate and indicating the angle. Zero-null feature allows for adjustment of zero +- 8° off of index origin. Manufacture from tool steel the spindle can be used in a wet environment with pressurization. This unit is sold motorized with v-block and 5C collet capabilities. Other face tooling options are available.

Grindit Spin Indexer product info.

Patented interlocking Vernier plates allow you to set the adjustable stops to 1 arc second accuracy quickly. The indexer can be left setup in the machine environment and adjustable stops can be moved in location. This model should be purchased if you are using non 15° stops on a weekly basis or less.

Stainless Steel Rotary Index Fixture – RIF-S  RIFS

This is the next generation in small spin and index fixtures.

Manufactured from stainless steel, containing ceramic bearings in a fully submersible package allows the unit to be used in most manufacturing environments, Wire EDM – Sinker EDM – Grinding.

An internal rotary encoder allows you to set up to 45 adjustable stops within 15 arc seconds accuracy. This eliminates the need for setting up using a sine plate and re-verifies your index position every time. Output is switchable between degrees decimal and degrees, minutes, seconds.

This unit is sold as a plain spindle. Motor drive options are the external motor usually used for dry grinding or the internal motor. The internal motor is integral to the RIF-S body allowing for fully submerged operations. The direct drive motor allows for full control 5-1800 RPM and reversing. Indexing accuracy improves to 6 arc seconds.

Options available are:

  • EDM grounding system for ensuring continuity in the EDM environment.
  • Leveling head to add or remove taper from a workpiece.
  • Adapter to rotate spindle to vertical orientation.
  • All face tooling options
