OMG BAH Series: Big Angle Head Series for Big Industry

The BAH Series of Angle Heads from OMG srl, Italy are designed and built to satisfy the tooling requirements of very large machines used in a variety of industries: Heavy goods vehicles, Aeronautics, Shipping, Military, Railroad, Energy, Moulds and Automotive.

To build these types of products, one needs design expertise, thorough knowledge of the product itself and related problems, investment strength, specific machine tools and equipment as well as highly qualified personnel. The applied technology, the materials, the parts and assembly all ensure top levels; the certified static and dynamic
tests guarantee the best possible performance over time.

They are usually special products, tailor-made for the specific requirements of the manufacturer of machine tools or for retrofitting machines already at work in the specific industries. The main features of these products may be summarised as follows:

  • Body made of cast iron or obtained from the full piece to ensure maximum precision and stability
  • Motion transmitted by means of Gleason ground involute gears. The transmission ratio is normally 1:1, but it may be in both multiplication and in reduction based on torque transmission requirements
  • Standard tool-holder couplings: DIN69871 – DIN 2080 – BT – HSK – Coromant Capto or others on request
  • Tool holder can be locked on the spindle in two ways: manually or automatically. If automatic, it is locked mechanically and released hydraulically
  • Coolant may be supplied in the centre of the tool holder. The pressure currently reached is 70 Bar and the tool holder is cleaned with air. Whatever the case, there are always some turning nozzles around the spindle

Furthermore, the spindle is always pressurised to avoid intrusions

  • Spindle oblique contact precision bearings lubricated with long life grease
  • Gears normally lubricated with grease separated from the grease of the bearings. For high speeds, the lubrication system is oil circulation
  • The axes of the heads with automatic rotation are locked by means of Hirth crowns, with standard division of 2.5° and 1° on request
  • All the electrical control devices on the axes and the spindles are inside the head and are easily accessed.

These products are tested statically on 3D measuring machines and dynamically, at the agreed rates, on our BP05 test bench that fully simulates the conditions of use in compliance with the product standards.

New MAPAL Tool Holders Programme

At a Glance
  • New design concept for chucks with added value
  • Brilliant surface finish and clear handling information
  • Expansion to the entire chuck programme planned
  • Corrosion-resistant chucks
  • Self-explanatory, straightforward handling – foolproof
  • Greatest possible stability with optimal usage of resources

Carefully considered Design taps Potential

Not only the appearance of the chucks was revised, above all added value for the customer was to be generated by means of carefully considered industrial design. Why? An ingenious design is not only a visual highlight, it also taps economic and ecological potential. Starting from this point, the product designers prepared, together with those responsible for the products at MAPAL, a new concept that is also based on function and FEM analyses.

The chucks designed according to this concept shine proverbially with a new brilliance. One of the elements in the new concept is the brilliant surface finish. This surface finish, produced by a specially developed polishing method, ensures that the chucks are more resistant to corrosion than in the past.

Easy, Self-explanatory “foolproof” Handling

A further requirement on the new design was so-called “foolproof handling”; that is the easy, self-explanatory handling of the chucks. Controls were to be identifiable as such more quickly with directly understandable handling information. These requirements were addressed, on the one hand, by the blue colour for the controls, such as the actuating screw on a hydraulic chuck and, on the other hand, by internally developed symbols that contain corresponding information, independent of the related language.

Last but not least the shape of the chucks, their weight and use of material were studied and optimised. The new shape addresses the requirements for the greatest possible stability with optimal usage of resources. Even the smallest weight savings on chucks have major effects that become apparent in use over the long term. Among other aspects, the lighter the chuck, the less energy is required during the acceleration and braking of the spindle.

Corporate design creates Recognition

Due to the new corporate design, the complete clamping technology range can be immediately identified as a MAPAL product – with a promise of quality and function.

 

OMG: TSI-TSX Series Adjustable Twin MultiSpindle Heads

 

 

 

 

 

 

The OMG adjustable Multi Spindle Heads TSI and TSX Series come with two parallel or convergent spindles that are especially suitable to mill and to chamfer gear teeth. Special care has been taken with the spindles bearing layout to withstand difficult machining conditions. The result is a solid, compact and reliable unit.

The adjustable multispindle heads TSI and TSX series have many different features: Aluminium body, Cast Iron spindle support, simple and easy to adjust by the operator.

The spindles may turn in the same direction or in apposite direction and the adjustment of both spindles is achieved thanks to a single act. The tool connection may be cylindrical shank or with spring collets. The lubrication is by long life grease. The production of the twin adjustable multispindle head is made possible by the experience acquired in the construction of multispindle heads, production process knowledge and know how to cater for individual requirements with qualified products.

HORN: New Supermini HP Geometry + Holder Systems

New Supermini HP and Holder Systems

The new HP geometry for SuperMini is suitable for drilling, boring, face turning and skimming. The new cutting geometry enables shorter machining times due to higher cutting depths. As well as the new geometries, Horn has developed a new holder system for the Supermini type 105. In addition to high repeatability when changing inserts, this results in a higher holding force of the insert and therefore a high rigidity of the overall system.
