Sandvik Coromant introducing CoroBore BC boring tools
Cutting tool and tooling system specialist Sandvik Coromant is introducing its CoroBore BC 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.
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 is prohibitive. The process is fast as Sandvik Coromant personnel utilise an online program that automatically creates the tool and provides price and delivery information.
“The productivity advantages offered by CoroBore BC tools are based on eliminating unnecessary tool changes and reducing cycle times,” said Jenny Nilsson, Global Product Manager, Sandvik Coromant.
“Among the many strengths of the new solution is the capability to offer these benefits at much shorter notice, thanks to an automated design and quoting process. The Sandvik Coromant representative simply goes through the required operations and parameters with the customer and enters the parameters via a web-based design interface. Once this is complete, the system instantly produces the tool design and quote.”
Thanks to the various CoroBore BC options offered, a wide range of multi-step boring applications can be performed. Indeed, customers can choose from up to four machining operations in a single tool, with a maximum of two cutting edges per operation. Cutting diameters range from 20 to 200mm, while tool length can be up to 400 mm depending on the coupling size. Coupling options include Coromant Capto, HSK Form A and ISO 9766, as well as ISO/Mas-BT/Cat-V tapers. The wide range of supported coupling models and sizes usually enables direct integration with the machine interface, thus eliminating the need to use a separate basic holder.
CoroBore BC insert-carrier solutions use CoroBore cartridges. Compared with fixed insert pockets, this configuration enables easy and efficient cartridge changes. As standard stocked items, both the insert and insert carrier are easily replaceable 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, a unique benefit in tailored multi-step boring tools.
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. All in all, the Sandvik Coromant insert programme offers productive geometries and grades for all types of materials and boring operations.
Ultimately, the unique benefits of CoroBore BC present machine shops with an option to receive a tool in a reduced lead-time in comparison with an engineered tool – and at a more attractive price point.
