Walter grows range for grooving applications

With the new WSM13G, WSM23G, WSM33G and WSM43G grades, Walter is expanding its Tiger·tec Gold range for grooving applications and also making it suitable for universal use. The diversity of the new grades ensures their suitability for everything from grooving and parting off to groove-turning, in virtually every material.

Walter developed the multi-layer Tiger·tec Gold PVD insert coating especially for the main types of wear that occur when grooving. The company says that the special performance of the inserts is credit to the combined TiAlN and TiSiN multi-layer coating. This makes the layers of the grades hard and resistant against both flank face wear and plastic deformation.

Complementing the multi-layer coasting is a special post-treatment process that ensures smooth rake faces, less friction and more toughness. Walter is offering the grades in four versions with different levels of hardness or toughness.

The WSM33G universal grade is suitable for 80% of grooving applications in steel, stainless and heat-resistant alloys. If the level of wear is too high, users can choose from two harder grades for ISO M, S and P materials. The WSM13G is suitable for finishing and medium machining with uninterrupted cutting, while the new WSM23G is for stable conditions, high-speed cutting and where machine shops are using oil as the cooling lubricant.

For particularly heat-resistant materials such as Inconel 718, Walter says that the WSM13G grade achieves maximum tool life in combination with 150 bar precision cooling. If a tougher grade is necessary, the WSM43G is suitable for interrupted cutting, machining at low cutting speeds or unstable conditions.

Walter is offering the new grades for all its grooving systems.

Boring inserts feature sintered chip breakers

Over the past 35 years, the Supermini universal boring system from Horn has undergone numerous development stages to solve problems in a variety of turning applications. The latest enhancement for the Supermini type 105 is a lower cost version of the solid-carbide inserts with chip-breaking geometry included at the sintering stage, rather than laser cutting or grinding them afterwards. Indeed, the price of the new Supermini is similar to that of the standard insert without geometry.

As with these previous machined chip breakers, the new sintered geometry avoids the drawback of long, stringy swarf coiling around the tool or workpiece and potentially causing damage to both. It assists with the internal machining of small diameter holes, whether boring, profile turning, internal grooving, threading, chamfering, face grooving or slot broaching.

Horn developed teardrop shaped carbide blanks for the tool, enabling large, precise contact surfaces in the tool holder and resulting in greater rigidity of the overall system. The teardrop profile also prevents the insert from twisting, which leads to consistent, precise positioning of the centre height of the tool. When using long tool overhangs, it reduces deflection and minimises vibration during turning.

Horn offers the inserts as standard in three lengths (15.0, 20.0 and 25.0 mm) and in carbide grades TH35 and IG35. The tool is suitable for use from a bore diameter of 6 mm, while the edge geometry extends far into the 0.2 mm corner radius of the insert, ensuring good chip control even with small infeed settings. It is possible to process different material groups and the geometry is suitable for internal, face, copy and back turning.More information www.phorn.co.uk

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.”

Ceratizit makes bespoke step drill for Volz

Rochdale-based Volz Engineering is a subcontract machining company that services the
automotive, aerospace and agricultural industries. With six CNC machines running 18 hours
a day, Volz sends out more than 500 parts a week.
Constantly looking for process improvements, a standout example of a tooling
recommendation which had tremendous impact was for a bespoke step drill. Required for a
job needing the drilling of one hole at different diameters at depths, Volz previously used

multiple inserts. However, swapping tools throughout the process reduced the overall
reliability and accuracy of the finished product, making it difficult to achieve the critical
tolerance of 0.02 mm. The machine process, with the necessary changes to tooling, took a
total of 26 minutes. This is where Ceratizit identified an opportunity to optimise the process.
Purposefully created to fulfil Volz’s exact specifications, Ceratizit designed and
manufactured a unique step drill. After installation, the total machine process time reduced
by more than 50% to just over 10 minutes. Moreover, using step drill requires just one
machine process to achieve the different diameters.
“The step drill was a game changer,” states James Alletson, operations manager at Volz
Engineering. “Not only did the time taken to machine each part dramatically decrease, but
with no machine interruptions we could achieve a greater level of precision. Since using the
step drill we haven’t had to replace it yet, despite the 500 parts a week it’s drilling.”
Impressed by the initial results of Ceratizit tooling, Volz began to switch out more tooling.
Indeed, a Ceratizit vending machine arrived on the shop floor around 18 months ago.

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.
