New Walter brand for lightweight materials

Walter Tools is raising its profile for the machining of lightweight components with the
arrival of its new FMT competence brand. The machining solutions provider is bringing
together its global presence and the technical expertise of lightweight machining specialist
FMT (Frezite Metal Tooling).
In the overall share of processed materials in the manufacturing industry, the proportion of
lightweight materials such as aluminium alloys continues to grow significantly. Machining
specialist Walter has therefore been consistently expanding this area of its portfolio for a
number of years.
The new Walter FMT competence brand showcases the importance of lightweight
machining for Walter to its global customer base and wider industry. It stands for the added
value that Walter says it offers customers through various services from consulting and
planning to implementation and maintenance, and for a trusting partnership that goes far
beyond tools.
As vice president of Walter Lightweight Business Unit, Pedro Pacheco will be responsible for
the new competence brand. He served as the first managing director of FMT from 2006 to
2017 and took over the role again in 2019.
“My focus will be on bringing together the expertise and working methods of FMT and
Walter’s PCD division in the optimal way,” says Pacheco. “We want to increase our reach in
the market significantly and contribute to Walter’s strategic growth targets. I want to create
the right structures and processes to provide current and potential customers with an
attractive offering that enables them to achieve their own economic goals.”

Introducing a smarter way to rough bore

Hole-making specialist Big Kaiser is expanding its modular CK family with new head types for rough boring. Available in the UK from Industrial Tooling Corporation (ITC), the new SW head for the CK1, CK2 and CKB3 boring tools includes Big Kaiser’s Smart Damper technology. This innovation minimises vibration and eliminates chatter, which is of critical importance when conducting rough boring operations.

Big Kaiser says the modular CK system is the world’s most versatile tooling system and, with support from industry experts at ITC, will exceed the performance and results of any other hole-making system. The new additions to the CK modular precision tool system are also available for the full Big Kaiser SW rough boring family.

“The Smart Damper SW heads offer six times higher boring efficiency with twice the cutting depth and three times the cutting conditions of other rough boring heads,” states Giampaolo Roccatello, chief sales and marketing officer for Big Kaiser Europe.

Based on a cylindrical connection with a radial locking screw, the CK system has been continuously improved over the years to meet changing needs and increases in machine tool performance. Compatibility with existing tools remains a stringent requirement for newly designed products. As well as interchangeability within the Big Kaiser family, the CK system is also fully compatible with all machine tool interfaces and enables customers to create tool assemblies specific to each machining application.

The integration of the Smart Damper shortens the distance from the damping mechanism to the cutting edge. This minimises vibration and enables the CK system to achieve better surface finishes and improved metal removal rates, while also prolonging tool life and enhancing surface finish.

New parting-off tool for small components

Kyocera Corporation has developed a new parting-off solution, denoted KGZ, for small component machining. KGZ uses a new clamp structure with three proprietary mechanisms to lock the insert in place, suppress chatter and achieve stable machining. In addition, the constraint surface of the holder has a shape that distributes stress, improves durability and realises high-efficiency machining.

Within the insert grade’s line-up, a newly developed PVD-coated grade known as the PR 20 is also available for the KGZ. The new coating, MegaCoat 1 Nano EX, which is resistant to oxidation and abrasion, achieves high precision, long tool life and stable machining when parting-off steel, stainless steel and cast-iron workpieces.

Notably, the new KGZ design improves the holding force of the insert and the durability of the tool holder through three proprietary mechanisms: gap section, top clamp and stopper.

With the gap section, users can simply press down on the insert from directly above to firmly secure it in place. Generally, it is structurally difficult to fix the insert directly above with a parting-off tool. KGZ has a tapered slit with a slanted cut, so when tightening the fastening screw it applies a restraining force from directly above the insert, securing it in place.

The top clamp serves to pull the insert inward and increase the binding force. Designing the shape so that force is applied inward when clamping the insert suppresses the displacement of the insert in the front and rear directions.

Kyocera’s stopper disperses stress over a large area and improves the durability of the holder. According to the company, this design reduces the amount of stopper wear to about one-third of that of competitor products.

Hexalobe is a star for the medical industry

With star-shaped hexalobular bone screws (TORX) proving the design of choice in the medical industry, Floyd Automatic Tooling is introducing the UK market to CrazyDrill Hexalobe drills and CrazyMill Hexalobe end mills from Mikron Tool.

Medical screws for orthopaedic procedures are predominantly manufactured from titanium, stainless steel and cobalt-chrome. Machining these precision screws to impeccable surface finishes is a challenging task – that was until the arrival of the Mikron Hexalobe series. According to Floyd Automatic, machining hexalobe screws 50% faster with precision burr-free results is what makes this next-generation series the first choice for manufacturers in the medical sector.

These high-performance drills for generating pre-holes in TORX sockets are available in two variants: the pre-hole CrazyDrill Hexalobe TORX drill with a tip angle of 140°, and the CrazyDrill Hexalobe Flat drill with a tip angle of 180°. Both are available from 0.9 to 3.8 mm in diameter for producing T4 to T30 TORX sockets. Upon request, Floyd Automatic can provide the drills as a customised combination drill for streamlining operations. The CrazyDrill Hexalobe series combines two operations into one, as it simultaneously machines a flat pre-hole and a 120° chamfer.

The Mikron CrazyDrill Hexalobe from Floyd Automatic generates chamfer surface quality to a finish of Ra<0.3 µm while guaranteeing high profile accuracy and perpendicularity.

Completing the process is the CrazyMill Hexalobe micro end mill. Available from 0.2 to 1 mm diameter for T4 to T30 socket variants, the CrazyMill Hexalobe presents three- or four-flute variants with milling depths of 3.5xD and 5xD. The CrazyMill Hexalobe milling cutter demonstrates sufficient stiffness for machining with high feeds and stepover rates, while guaranteeing the necessary hex lobular profile accuracy.

Mapal gains foothold at Kramer+Grebe

To stay competitive in mould and die making for the automotive industry, efficient production with a high degree of process reliability is vital for Krämer+Grebe of Biedenkopf-Wallau. Manufacturers such as Krämer+Grebe also judge cutting tool suppliers by their applications engineering. Mapal is earning trust in this respect with its reamers and high-feed milling cutters.

Machinery at Krämer+Grebe is all state of the art. The 16 machining centres are predominantly from DMG and Hermle. There is also a deep-hole drilling machine, two turning centre, three EDM machines and 3D printers. The company has 11,000 m²

of production space at its disposal, where the transition to electric mobility is well underway. Powertrain parts here include stator housings for the electric motor.

Co-operation between Mapal and Krämer+Grebe is reaching its five-year anniversary, a partnership which began with multi-bladed reamers. Mapal was the only manufacturer Krämer+Grebe could find that was able to produce these tools with the necessary quality and short lead times. Bores with H7 quality are needed to insert heating cartridges in low-pressure moulds.

Mapal’s application engineers left a lasting impression. They provided user training on site and helped commission the process on the machine. As part of process optimisation, Krämer+Grebe parted company with some of its former tool suppliers, of which there were many.

After such a good experience with the reamers, Krämer+Grebe began adopting Mapal’s high-feed milling cutters. The tools demonstrate long tool life and generate large chip volumes during roughing, thus reducing production times. The milling cutters are also extremely reliable to allow for multi-machine operation.
