“Our Feed Rates are Higher than we Expected”

by Markus Isgro 17. December 2018

The Swiss company Humbel has been involved in gear production since 1928—specializing in particularly sophisticated types of gears and transmission components, eventually evolving into a full-service supplier. At their facility in Kradorf, approx. 20 kilometers (12 miles) from St. Gallen, they produce both individual parts as well as complete assemblies. The company recently expanded their machine inventory to include a VL 4 vertical turning center by EMAG. — We spoke with Alex Humbel, Managing Director of Humbel Zahnräder AG in Kradolf, on the challenges facing gear producers, the importance of E-mobility, as well as their company strategy.

Hobbing Machines from EMAG Richardon: Built-In Flexibility

by Markus Isgro 6. December 2018

In many ways, the production of large components presents a particular challenge in manufacturing. Used in commercial vehicles, large transmission, or wind power, these parts are large – making them difficult to handle and slowing down production speeds. Adding to the production challenge is the additional technological requirements being placed on the parts, as well as the demand for improved reliability and precision, with decreased costs per piece. All of which needs to be achieved while improving process speeds.

Cylindrical grinder HG 208: the precision-fit shaft grinding solution

by Markus Isgro 21. February 2018

Cylindrical grinding on driveshafts and transmission shafts has always been particularly demanding, as the parts feature a wide range of geometric details that are machined with high precision in the grinding machine. With the rapid pace of technological development in the automotive industry, which keeps increasing the functional density of many components, there are more demands than ever on the design of grinding machines today. Users require highly customized machines that can perform multiple grinding operations, including combined internal and external grinding.

HLC 150 H by EMAG: Complete Gear Cutting Solutions

by abakun 13. September 2017

Maximum flexibility is required for gear production. EPS steering is a good example: Production planners for this application are looking for machines that can efficiently and completely cut an EPS steering gear including steering pinion, worm gears, and screws. The HLC 150 H horizontal gear cutting machine from EMAG KOEPFER is the perfect solution for this.

EMAG Pick-Up Lathe vs. Sub-Spindle Lathe

by abakun 18. August 2017

The EMAG Inverted Spindle Pick-Up Lathe process provides for a significant improvement in accuracy versus that of a sub-spindle lathe.

Lathes with sub-spindles pass a part from one rigid work holding system to another. This does not allow for any misalignment of the two spindles. The first spindle cannot release a part until the second spindle has a secure grip on it. Allowing for mismatches on a split turned dimension such as a bore. The accuracy and quality of the workpieces that are produced from this system are compromised because of this process.

VL and VSC machines: Efficient Machining of brake discs

by abakun 19. April 2017

Increasing cost pressure, high demands on part quality and frequent change of batches – the manufacturing of car brake discs is a difficult field. Particularly in the spare parts market, where users must request individual machining solutions that can be retooled for new workpieces without long downtimes.

VLC 200 GT: Machining of Automotive Gears

by Markus Isgro 27. February 2017

The VLC 200 GT is loaded at by the integrated pick-up spindle. The process starts with hard pre-turning of the shoulder and the bore hole in quick succession. Only a few micrometers of material are then left to be removed from the automotive gear by the subsequent grinding process, using either aluminum oxide or CBN grinding wheels.

VLC 200 GT: High-precision, efficient hard machining of passenger-car gearwheels

by Markus Isgro 20. February 2017

Transmission manufacturing is among the most innovative areas of passenger vehicle production: This central component has to ensure a high level of driving dynamics, while keeping fuel consumption low at the same time. Transmissions are therefore becoming smaller and lighter, and provide a higher number of speeds. The individual gearwheels are a main focus of the developers. Their production in extremely high volumes requires a high level of efficiency—at high precision, high speed, and highly controlled.
