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 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,” says Jenny Nilsson, global product manager at 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 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 range of multi-step boring applications can be performed. Indeed, 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 200 mm, while tool length can be up to 400 mm, depending on 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.
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.
