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.

EMO 2019 : Knoll Showcases Global Competence

KNOLL Maschinenbau at EMO 2019
Hall 7, Booth C34.

At EMO 2019, the world’s premier trade show for metal processing, KNOLL Maschinenbau will present itself as a global player, whose products –  Conveyors and Filtration Systems, Pumps, and Transport Systems – are widely used in plants all over the world.  KNOLL supplies not just innovative machine tool components, but also large turnkey central systems for coolant, lubricants and chip management.

  • Knoll Central Systems

KNOLL’s core business – systems for cooling lubricant and chip management – has taken on new dimensions. In addition to outstanding standard components for machine tools, there are also numerous large Central Systems, which KNOLL has delivered to metal processing production operations all over. These systems can supply 30 or more machines with up to 12,000 l/min of extremely clean cooling lubricant. Modular system technology enables them to achieve still greater total output. At EMO visitors can get an impression of this expertise.

In Hall 7, Booth C34, KNOLL will present cooling lubricant in the form of a stand-alone solution for two-stage cooling lubricant filtration.  After the show, this machine will be used by a customer in an HSS grinding shop. It contains a 240/AK5 MicroPur®filter, which is supplemented by a KNOLL KF 400-E compact filter with an endless filter belt. It handles the task of chip pre-separation, making superfine filtration easier.

Innovative Standard Components

The basis of every large system is innovative standard components that are also used in many individual machines. These include the modular superfine MicroPur® filter, which is designed to remove residues from grinding processes, whether carbide metal, HSS or Cast particles. At EMO, KNOLL will present the MicroPur® in the 120-F version, which contains two back flushable filter elements for approx 120 liters of filter capacity. It is particularly cost-effective when working with the integrated KNOLL AK5 automatic concentrator, which reduces the carryover of oil and can ensure a residual moisture content in the settled material of less than or equal to 10%.

For over a year, KNOLL Maschinenbau has offered the LubiCool® mobile high-pressure station for use on short and long automatic lathes. It supplies cooling lubricant at up to 150 bar, which ensures short processing times and longer tool service life for short-breaking chips. Machines are made suitable for even the most challenging of machining processes, such as machining high-alloy steels or titanium. The built-in belt filter with a filter fineness of up to 20 µm guarantees the cooling lubricant purity that is required for high-pressure applications.

At EMO, the “big brother” LubiCool® L will celebrate its premiere. It is designed for larger lathes and small and medium-sized processing centers that require higher flow volumes and flushing processes. Here, high-pressure pump KTS 25-50 can be used with a TG 30 centrifugal pump for flushing. Optionally available for integration is a BS 40 lifting pump, which guarantees independent high-pressure and supply systems.

Both LubiCool® variants use the new SmartConnect operating concept, with which a small industrial PC is connected to the PLC system. Using a 7″ touch display, the user can access the system, visualize states, check parameters, and thus change to manual mode.

Refreshingly Different – the Modular Machine

Based on the structural principles of a processing center and an ideal presentation platform for KNOLL OEM products: the Modular Machine.  KNOLL will display its Plate Conveyor design, as an example, whose distinguishing feature will be plates that are joined hinge-free so that it is suitable both for chip removal for wet and dry processing, as well as conveying small sheet metal parts.

For applications that create very fine, lightweight chips, KNOLL has developed another complementary solution: an attached, self-priming BS 40 dirty water pump which conveys cooling lubricant that contains chips into the chip separator, using the cyclone principle to separate the chips from the cooling lubricant and store them in the ascending area of the conveyor belt. The pre-cleaned coolant flows directly to the filter system.

This is present on the Modular Machine in the form of a KF 150/650 Compact Filter. The universally applicable tower model belt filter saves space since the filter elements sits on the tank.

As a conveyor alternative, the Modular Machine includes an RKR return pumping station with chip reducer, which will demonstrate how cooling lubricant and chips can be transported away from the machine reliably, cleanly, and in space-saving fashion to a central separator/filter.

At EMO 2019, the Modular Machine will, for the first time, contain a fluid cabinet, which includes a pressure boosting system with KTS screw pump, valve technology, and control filter.

MMS instead of Cooling Lubricant

For many chipping applications, Minimum Quantity Lubrication (MMS) is an alternative to using cooling lubricant. For this, KNOLL offers the modular ControLube MMS system, which works with injector technology and microprocessor control. The system developed by KNOLL already delivers a particularly fine aerosol within 0.1 seconds, which provides for improved process conditions, shorter processing times and lower costs. A core property of this MMS system is the oil quantity that can be regulated regardless of the air pressure; it is also available in the simplest ControLube model. Depending on requirements, the system can also be retrofitted process-specifically with additional modules and, for example, with a controllable air pressure of up to 20 bar.
