New chucks use ER-driven tools for versatile turning

“The best of both worlds” is how German tooling manufacturer GEWEFA describes its M96 and M96+ hydraulic chucks, which fit into any ER-driven tool quickly and effectively for conversion into a high-precision hydraulic holder. Availability in the UK and Ireland is through subsidiary company GEWEFA UK, which offers the products from stock in Germany.

Avoiding the limited clamping force, runout issues and lengthy tool change times associated with mechanical ER holders, the versatile M96/M96+ products give the machinist all the benefits of hydraulic clamping. These include higher and more consistent all-round gripping force, effective vibration damping, extended tool life, higher accuracy and improved surface finish on machined components. GEWEFA says all this is available at a much reduced cost compared with standard hydraulic chucks.

In addition, because the chucks simply mount in the output shaft of the ER driven tool and twist to seal, users can enjoy quicker and easier tool changes, saving time and increasing productivity.

The M96 is suitable for driven tools with an internal thread, while the M96+ is for driven tools with an external thread and is secured to the live tool with a locknut. GEWEFA’s new hydraulic chucks are available for sizes ER16, 20, 25, 32 or 40 (currently only the M96), accommodating tool diameters from 5 to 25 mm.

CUTTING TOOL MANUFACTURER MAPAL CELEBRATES 75 YEARS

In a history now spanning 75 years, family-owned and operated MAPAL has gone from
humble beginnings to an international group with a global reputation. From the beginning,
the Germany-headquartered tool manufacturer’s company history has been characterised
by continuity and an innovative spirit that was nourished by Swabian ingenuity and
creativity, as well as by the entrepreneurial courage of the Kress family. Close contact with
customers and a reliable sense for what will matter in future continue to shape the
company’s culture to this day.
The foundation of the company in 1950 was quite unusual. Dr Georg Kress held a doctorate
in economics and was working as a tax advisor when the opportunity came up to take over
one of his clients’ companies, which had got into difficulty. Although he knew nothing about
threading tools and dies, he bought OBA Präzisionswerkzeugbau from Otto Betzler. He sold
his successful tax advisory firm in Aalen and became an entrepreneur.
The new name for the business, MAPAL, stood for ‘Maschinen- und
Präzisionswerkzeugfabrik Aalen’, and is testament to the fact that woodworking machines
were also manufactured in the company’s early days. As cost-effective and efficient
production of the profile milling machines was not possible in the long haul in the cramped,
simple premises on Obere Bahnstraße in Aalen, MAPAL quickly moved away from this area
of business. The focus switched to tap drills, thread dies and thread rollers, which marked
the beginning of the product range for which the company is known today.
The purchase of a patent for an innovative reamer in 1952 proved to be a visionary move for
the company’s long-term success. Unlike previous designs, it does not have four or six
cutting edges, but rather only one, which is clamped into a slot and can be adjusted. The
Italian inventor promised this would achieve lower manufacturing costs and more flexibility
in reaming. When Dr Georg Kress acquired the patent for the single-bladed reamer, he was
going against the advice of technicians from his own company, who felt the tool was
unsuitable. And they were correct, in principle.
However, Dr Kress drew on R&D to overcome these initial problems. In a painstaking and
meticulous process, the reamer was improved. This included inserting two guide pads
asymmetrically around the circumference of the reamer body. In 1954, the first single-
bladed reamer developed by MAPAL with guide pads made of carbide was patented.
Another patent for a reamer with indexable inserts made of carbide followed in 1962. Both
innovations laid the foundation for developing the reamers into an appealing, high-

performance tool in the coming years. The fine machining of bores became MAPAL’s calling
card.
When Dr Dieter Kress joined the family business in 1969, the son of the company’s founder
was well prepared for his future duties. Unlike his father, he was at home with all things
technical. On his very first day working at MAPAL, he designed a new clamping method for
indexable inserts. It was patented and in principle still forms the technology for clamping
the indexable inserts in MAPAL reamers today.
When he became president in 1974, Dr Dieter Kress quickly set about redesigning the
product portfolio. The tap drill and thread roller area of the business was given up to focus
completely on reamer production. This came at a time when two-thirds of MAPAL’s
turnover came from threading tools. But entrepreneurial foresight lay behind this plan. The
long-established products offered almost no potential to differentiate the company from
mostly bigger competitors who could also manufacture at a lower price. The single-bladed
reamer, by contrast, was something very special, with no direct competition. However, the
market had to be developed first.
The reamers were gradually developed until they were suitable for industrial large-scale
series production. Coating of the indexable inserts played a role, as did the use of PCD for
the guide pads. The tools helped MAPAL gain a foothold in the automotive industry first and
foremost, where manufacturing technology was moving from rigid transfer lines to flexible
machining centres.
Alongside technical improvements, MAPAL rebuilt its sales concept and focused on
maximum customer proximity. Independent sales representatives were replaced with in-
house technical consultants whose role was to advise customers on the ideal, customised
design for their tools and to support them with their use. In the automotive industry the
collaboration became so close that the consultants even became involved in developing
new engines by introducing potential precision machining options into the design process at
an early stage. They did not just sell tools – they sold solutions.
MAPAL opened its first subsidiary in the US back in 1977. But the global expansion truly took
flight in the 1990s. MAPAL established numerous overseas subsidiaries in quick succession.
MAPAL’s internationalisation strategy was based on following its big customers. As they
were setting up production facilities virtually all over the world, the comparatively small
company from Aalen had the opportunity to join and leverage market potential. MAPAL is
now represented in 25 countries with its own subsidiaries.
To expand its product and service portfolio, which also followed customer requirements,
MAPAL acquired specialist companies in Germany. WWS in Pforzheim expanded MAPAL’s
offer to include PCD tools with brazed blades for high-speed machining, particularly of
aluminium, thus covering a segment that was becoming more and more important to
customers. Solid-carbide drills and milling tools were added to the range courtesy of Miller

in Altenstadt. As drilling from solid is the production step prior to reaming, this made a
suitable addition to MAPAL’s portfolio. Weisskopf from Meiningen strengthened the solid-
carbide segment further.
The purchase of the long-standing Winterlingen-based company August Beck secured
MAPAL’s position as a leading manufacturer of reamers, while Robert Strom and ISOTOOL
added ISO and actuating tools to the portfolio. In 2015, the two companies were rebranded
MAPAL ITS, which focuses on complex special tools with actuating mechanisms in Eppingen.
Clamping tools from WTE in Ehrenfriedersdorf completed the product range. MAPAL made
further strategic investments overseas.
The third generation joined the family company’s executive management in 2008 with Dr
Jochen Kress, who had already been working at MAPAL as a development engineer since

  1. When he took the helm of MAPAL Group as president in 2018, the market’s
    transformation was in full swing. MAPAL is proactively engaging with the automotive
    industry’s transition to electromobility and developed efficient manufacturing solutions in
    this area early on.
    There was also a strategic expansion of customer segments beyond the automotive
    industry, which had been a guarantee of growth over decades. MAPAL now also focuses on
    the aerospace, fluid power technology, and die and mould segments.
    Digital solutions are provided by c-Com since its founding in 2017. The start-up has been
    merged into the MAPAL Group and primarily assists with tool management services. The
    company takes all aspects of sustainable management into account with an environmental
    management system – with many individual measures in production and administration at
    all sites making their contribution.
    Dr Jochen Kress initiated the transformation of MAPAL into a process-driven, global
    organisation. Structures and processes are being adapted to the size the company has
    reached; decision-making processes are being streamlined and accelerated. The
    reorganisation on management level at headquarters in Aalen is based on core processes
    and areas of focus. The structural, organisational and cultural changes that Dr Jochen
    Kress initiated will shape the company in the long term and endure long beyond the
    anniversary year 2025.

EMO 2025: Highlights in turning machines from Index

Among the machine highlights on the stand of Index at the EMO 2025 exhibition last week was the Traub TNK40 production turning machine, a pure short-turning machine developed on the basis of the Traub TNL32 compact Swiss-type turning machine. Instead of the sliding-head for Swiss-type turning, the TNK40 has a fixed headstock with a spindle diameter of 40 mm. Thanks to the low-vibration and simple bar feed, the machine achieves higher overall rigidity than the Swiss-type turning version, which is reflected in increased dynamics and component quality.

Another new addition to the portfolio on show at EMO was the Traub TNL12 lean Swiss-type turning machine. This cost-effective entry-level model is configured with only one turret and one rear unit. The driven guide bush is adjustable but not programmable. Optional extensions are of course still possible.

Complete machining and automation are of course setting a trend across all industries. Index demonstrated what a practical solution can look like at EMO 2025 using the example of the Index G200.2 and G320 turn-mill centres with the iXcenter robot cell.

Among the technological innovation on show was High Dynamic Turning (HDT), which Index has further developed into HDT 2.0. In this process, the setting angle of a turning tool is continuously adjusted using the C axis of a motorised milling spindle. Index has developed a new input mask for HDT 2.0 that allows this process to be programmed easily and efficiently directly at the machine. This capability eliminates the need for numerous tool changes, as even very complex turning contours can be machined with just one tool.


Index also presented a solution that enables HDT on a turret and even on a multi-spindle automatic lathe.

DMG Mori presents world premiere at EMO show

DMG Mori provided the second generation of its NLX 2500 |1250 universal turning centre with its world premiere at the EMO 2025 exhibition in Hanover last week. According to the company, the machine represents a new era of universal turning, in which flexibility and intelligent technology go hand in hand – in all key industries, from mobility and medical to aviation and space. It meets high demands for precision, productivity and efficiency with stability, integrated processes and individual automation options.

As the new universal turning machine in the portfolio, the versatile NLX 2500|1250 2nd Generation proves its importance in the context of the so-called era of machining transformation (MX). The MX connects all areas of ‘DMG Mori World’ and redefines industrial value creation. Four strategic pillars form the backbone: process integration, automation, DX and green transformation (GX). Each of these pillars addresses key challenges facing the manufacturing industry: productivity, flexibility and sustainability.

For example, to demonstrate process integration, DMG Mori offers multitasking machines such as the DMC 125 FDS duoBLOCK μPrecision, which was demonstrated at EMO performing milling, turning and grinding in a single clamping. Such a solution releases capacity on other machines, reduces the need for manpower and relieves the burden on employees. At the same time, models of this type increase machine utilisation to up to 7000 hours per year.

DX connects the entire production process. In this context, CELOS X from DMG Mori serves as an intuitive, app-based control and operating system that supports users from order planning and programming to process optimisation. All machines with CELOS X use the GREENMODE, which reduces the energy and resource consumption of the machines by up to 30%.
