Reliable thread turning in tight spaces

Published

on

Walter AG is completing its range of MX grooving inserts with the A60 and AG60 geometries for small to medium pitches. Just like the existing MX geometries (CF5 and GD8 for all grooving and parting off tasks, RF5 for grooving and copy turning), the A60/AG60 inserts are also designed with four cutting edges.

The geometries are made for creating 60° partial-profile external threads in a wide range of pitches (0.5–3.0 mm) and are particularly suited to thread turning in tight spaces, like near a shoulder or counter spindle. In addition, the system offers general advantages like excellent cost-effectiveness or the ability to use all inserts universally with one toolholder on the left and right.

The MX system is suitable for all materials and enables insert widths between 0.8 and 3.25 mm and cutting depths of up to 6 mm. One special feature is the design of the insert seat: Due to the self-aligning tangential clamping, the insert is pressed against the contact points when the screw is tightened. A special dowel pin helps with accuracy of fit and simultaneously makes it impossible to mount the insert incorrectly. That results in a high degree of dimensional stability and repeat accuracy. The fact that the insert contact surface is not ground when creating the cutting edge width, and the entire insert thickness is therefore maintained, also contributes to the high stability of the MX system. Special profiles outside the standard range are offered by Walter from ten pieces and are available via the Walter Xpress service within four weeks.

Sandvik Coromant showcasing new paths to success in Stuttgart

Published

on

At this year’s AMB exhibition (Stuttgart, 18-22 September), Sandvik Coromant intends to show how customers and partners can achieve significantly higher productivity levels, more flexible machining processes and more sustainable production under the strapline ‘Shaping the future together’. For instance, the global specialist in cutting tools and tooling systems will be revealing how it is revolutionizing the world of turning, improving the entire manufacturing process with digital connectivity solutions and offering fascinating possibilities for the automotive and aerospace industries.

On Stand E50 in Hall 1, Sandvik Coromant will present digital solutions designed for smarter machining and greater manufacturing efficiency. These innovations will include CoroPlus® ToolGuide, which provides fast and precise tool recommendations for the specific operation and material type, as well as CoroPlus® ToolLibrary, which enables users to integrate tool assemblies directly into their digital machining environment. Along with software that helps improve design and production planning, the company will showcase networked tool and process-control solutions.

Trade visitors can also discover the latest technologies in the fields of turning, milling and drilling at the 375 m2 stand. Included will be turning solutions such as CoroCut® QD for cutting with the Y axis. CoroCut® QD uses the potential of modern turning centres and multi-tasking machines to guide the tool in the Y direction, positioning the upper side of the indexable insert parallel to the end of the blade. This capability enables faster feed speeds and the machining of longer overhangs without loss of stability.

Also being promoted at the show will be the PrimeTurning™ process for turning in all directions. Manufacturers in the automotive and aerospace industries, in particular, can benefit since PrimeTurning™ is extremely versatile. Indeed, the process is suitable for turning short, compact components, for longitudinal turning, and for machining contours and front-end geometries.

“We are looking forward to another great AMB because this trade show always offers an excellent opportunity to meet customers and partners personally in order to optimize future co-operation,” says Josse Coudré, General Manager Sales Area Central Europe at Sandvik Coromant. “We are proud to present our high-end solutions in Stuttgart, all of which are designed to help manufacturers become more efficient, productive and profitable.”

Thanks to numerous co-operations with machine manufacturers, including being a co-exhibitor on the DMG Mori stand, solutions from Sandvik Coromant will be on display in many places around the exhibition. Sandvik Coromant is also one of the sponsors and speakers at the special two-day AMB show ‘Digital Way 2018 – Digital Paths in Production’.

The Sandvik Coromant service team will again support and advise customers before and during AMB. A five-man technical crew will be available one week before the start of the trade fair in Hall 5, Room 5.3.
