OMAP: Self-centering chucks, autofretting face drivers and flanges

OMAP self-centring chucks

The Ultimate Tooling is now located in Belluno, in the heart of the Italian Alps, where OMAP, a leading manufacturer of accessories for shaft grinding such as self-centering chucks for lathes and grinders and crankshafts, face drivers, lathe platforms and flanges.

The history of OMAP

Omap, whose acronym stands for Officine Meccaniche Alta Precisione, was established in 1963 by its founder Luigi De Pra, who was succeeded over the years, first by his son Roberto De Pra and then by his grandson Luigi De Pra, the company’s current general manager.

Omap is an all-Italian company covering an area of more than 3600 square meters, employing about 15 people, and producing about 1,500 units annually.

And it is precisely Luigi, the representative of the third generation, to guide us inside the structure and to let us know the products and manufacturing techniques that have been applied during the realization of the self-centering chucks.

OMAP: self-centering chucks for lathes, mills and crankshafts grindings machines

Going into specifics, Luigi De Pra explains that OMAP’s business is mainly focused on the manufacture of self-centering chucks for crankshaft grinding, milling machines, and lathes.

In addition, autofretting face drivers, lathe platforms and bracket flanges are realized.

But what remains the strong part of OMAP production is definitely the manual self-centering chucks for lathe, in the following variants:

  • Self-centring chuck 3 double-guided jaws
  • Self-centring chuck 4 double-guided jaws
  • Couple of self-centering chucks for crankshafts grindings machines

Production of self-centering chuck

Luigi De Pra points out that the entire chucks manufacturing process takes place internally at OMAP plants and illustrates the various steps of implementation.

Before knowing the whole process, however, it is necessary to point out that the production department is equipped with extremely state-of-the-art machinery and can rely on:

  • 4 fadal machining centers
  • 2 pink tangential corrections
  • 1 robbi outdoor grinding
  • 4 cmt brand numerical control lathes
  • Fanuc wire EDM
  • Moldmaster die-sinking EDM

Production process of OMAP self-centering chucks

It starts with the raw castings or special steel bars which will be worked with turning and milling operations.

To give the characteristics of hardness and resistance to the self-centering chucks, the material is subjected to heat treatment in the furnace department and then the first grinding step is carried out.

After that, we move to the delicate step of manual adjustment of the self-centering chucks, made exclusively by experienced professionals; this is the passage that determines the accuracy and finishing of the workpiece.

After taht, the self-centering chucks is ready for further grinding cycle, with regard to the body and the jaws.

Now it’s time for cleaning part through a special washing machines and the use of special cleaning products that keep the technical and mechanical characteristics of the self-centering chucks unchanged.

At the end, every single OMAP self-centering chucks is subject to strict testing and final quality control.

Sales and distribution network

Once the test phase has been successfully completed, the self-centering chucks, as well as autofretting face drivers, lathe platforms and flanges, are ready to be delivered to final customers in every part of the world.

In fact, through an efficient distribution network, OMAP products are widely recognized and appreciated everywhere, both at home and abroad.

Luigi lets us know that sales are cyclical, but in recent times, it is especially the markets of the U.S. and Russia that have seen the greatest demand for OMAP products.

Future projects

As OMAP is a company that is always focused on growth and perfecting its production, Luigi informs us that the purchase of a new ISO 50 2-blade CNC machining center and a pink external grinding machine has already been finalized.

In addition, the growing interest of omap products, in the Middle East region, requires the search and formation of new business partnerships with local distributors.

Conclusions

We have come to the end of this in-depth visit to the OMAP high-precision machine shops.

We would like to thank the general manager Luigi De Pra for the time he gave us and for the explanations he gave regarding the production of the OMAP self-centering chucks.
