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.

JBO: Custom Precision Thread Gauges

Special Thread Gauges and Inspection Machine Mountings

We are pleased to offer special custom precision gauges and inspection machine mountings from Johs Boss GmbH & Co KG, Germany.  Thread gauges are used to measure various types of threads.  Plug gauges are used to measure internal threads and Ring gauges are used to measure external threads.

Examples of special gauges are shown below.

 

 

GO/NO GO thread plug gauge and GO thread ring gauge for customer-specific 3-starts special thread.

 

Multiple GO thread plug gauge and GO thread ring gauge M 12.5 x 6 P 0.75 – 6g (8-starts). Maximum quality with ground thread.

 

GO/NO GO thread plug gauge and GO thread ring gauge for customer-specific asymmetric special thread.

 

The coordinate gauge rod determines the position of an internal thread via a 3D measuring machine.

 

 

GO/NO GO thread plug gauge with increased stem diameter for checking small, deep seated threads.

 

GO thread ring gauge with DLC coating provides outstanding wear.

 

Gauge for checking the minimum bore diameter and concentricity of the bore with an internal thread.

JBO Calibration Services for Thread Gauges

If you require thread gauges with a documented calibration certificate, JBO issues a calibration certificate generated in their metrology laboratory. The inspection is carried out in accordance to determined directives, for e.g. acc. DAkkS-DKD-R 4-3 page 4.8/4.9 and is adapted to the intended standards and factory standards of each test item (DIN, ISO, ANSI, etc.).

The scope of testing (see index “Order-Code”), the exact specification, the uncertainty of measurement and the type of inspection are always completely described on the calibration certificate. The traceability to national and international standards is guaranteed. Therefor our standards are recalibrated regularly by an accredited calibration laboratory. On request we supply DAkkS-certifcates or certificates established by an accredited partner-laboratory.

Please contact us for any special gauge requirement.  Our team will be happy to help you with more information.

 

Horn Milling System 406 with Wiper Geometry

Milling System 406 with Wiper Geometry                     

Paul Horn GmbH has extended the 406 tangential milling cutter system to include an insert with wiper geometry for finishing. The new insert has been developed in response to demand from Horn’s customers, reflecting the fact that surface quality requirements are constantly increasing. The new geometry produces very high surface qualities, even at high feed rates, resulting in shorter machining times. Moreover, the geometry makes it possible to reduce the need for subsequent grinding processes.

The single-edged finishing insert is used in the 406 system’s 90-degree shoulder mills. Only one insert with wiper geometry is required in the tool body. The remainder may be standard 406 system indexable inserts. The wide finishing insert is available in grade AS4B for the workpiece material groups P and M, and in grade AS46 for workpiece material group K.

KNOLL AerosolMaster® System with ATS Technology

KNOLL Maschinenbau, Bad Saulgau, has replaced its Minimum Quantity Lubrication system ControLube with the AerosolMaster®system, which is based on ATS technology (aerosol dry lubrication). The system can be supplemented by cryogenic cooling technology. This has come about by the KNOLL acquisition of Rother Technologie GmbH & Co. KG, Bad Urach, including all of its patents, retroactive to July 1, 2019.

For five years, KNOLL Maschinenbau, one of the leading suppliers of conveyor and filtration systems for chips and cooling lubricants in metal processing, has been offering an alternative to wet-cooling lubrication. Managing Director Matthias Knoll is certain that “There are production areas where the future clearly belongs to minimum quantity or dry lubrication.”

Matthias Knoll is sticking to his opinion, even though the company is now discontinuing its previous MQL product – the high pressure ControLube system: “Because of its lubricating results, ControLube is a very good system that produces a particularly fine aerosol. Its disadvantage: It requires a lance through the spindle, which many machine tool manufacturers can not implement. With AerosolMaster®, we have now found an alternative lubrication system that achieves a comparably fine aerosol but is much easier to implement in the machine.”

Rother Technologie. Managing Director Reiner Rother explains: “We were looking for a partner or successor to whom it would make sense to hand over our MQL know-how, which has been acquired over nearly 25 years, and who will continue our products in the long term. KNOLL Maschinenbau, with its experience in the MQL business and its worldwide sales and service structures, was a desirable candidate for us. ”

At EMO, Reiner Rother further described the features of the AerosolMaster® : “Even without a lance in the spindle, we can perfectly lubricate the tool cutting edge and prevent heat from machining.” The technology behind it: The fine aerosol (droplet size 0.1 μm to 0.4 μm) is produced in a pressure vessel via a special venturi nozzle and patented control and regulation technology. Like the usual cooling lubricants, the aerosol is guided along a single channel, for example, through the internal cooling channels of the tool to the cutting edge.

In addition to the high aerosol quality, which has been repeatedly verified at Knoll, Matthias Knoll was particularly impressed by the simple installation: “Not only conventional MQL systems can be converted to the AerosolMaster®. Without much difficulty, it is even possible to convert many wet-cooled machines.”

With the acquisition of Rother, KNOLL has yet another trump card up its sleeve: The AerosolMaster® can be combined with the cryolub® cryogenic cooling technology – also patented by Rother – for example, into the AerosolMaster® 4000 cryolub®. By using liquid CO2, the cutting contact zone can then be cooled down to -78 °C. This is particularly advantageous in the case of heavy-duty machining of titanium and other materials that have a low thermal conductivity. Reiner Rother summarizes this in figures: “With the ‘normal’ AerosolMaster®, we can achieve a productivity increase of 30 to 70 percent; with the cryo system, the increase is even greater, between 70 and 200 percent.”
