Cutting-tool and tooling-system specialist Sandvik Coromant has introduced its CoroBore BC (boring combination) range of solutions, which comprises tailor-made tools for high-volume applications.
Using CoroBore BC, it is possible to perform different operations, such as semi-finishing and chamfering, with a single tool. Manufacturers set to benefit include those serving the automotive, general engineering and construction equipment sectors.
Sandvik says CoroBore BC offers a quick and easy alternative when standard tools do not match up to specific requirements, but the cost and delivery time of a specially engineered solution are prohibitive.
The company says the process is fast, as its personnel use an online program that automatically creates the tool and provides price and delivery information.
Jenny Nilsson, Sandvik Coromant’s global product manager, said: “The productivity advantages offered by CoroBore BC tools are based on eliminating unnecessary tool changes and reducing cycle times. Among the many strengths of the new solution is the ability to offer these benefits at much shorter notice, thanks to an automated design and quoting process.”
With various CoroBore BC options offered, a wide range of multi-step boring applications can be performed. Customers can choose from up to four machining operations in a single tool (a maximum of two cutting edges per operation).
Cutting diameters range from 20 to 200mm, while the tool length can be up to 400mm, depending on the coupling size and type (options include Coromant Capto, HSK Form A and ISO 9766, as well as ISO/Mas-BT/Cat-V tapers).
CoroBore BC insert-carrier solutions use CoroBore cartridges.
Compared with fixed insert pockets, this configuration allows easy and efficient cartridge changes; and being standard stocked items, both the insert and the insert carrier can be easily replaced at short notice.
The cartridges come in three configurations: radially and axially adjustable; axially adjustable only; and non-adjustable.
All cartridge options are equipped with high-precision coolant nozzles capable of using coolant pressures up to 80 bar.
In addition to standard ISO inserts, CoroBore BC boring tools can be fitted with proprietary CoroBore 111 inserts, which come with optimised grade options for medium and rough boring.
