Sandvik Coromant's CoroBore BC Performs Semi-Finishing and Chamfering
Sandvik Coromant’s CoroBore Boring Combination (BC) is designed for high-volume applications.
Sandvik Coromant’s CoroBore Boring Combination (BC) is designed for high-volume applications, performing semi-finishing and chamfering in automotive, general engineering and construction equipment applications.
Cutting diameters range from 20 to 200 mm (0.787" to 7.874"), while tool length ranges to 400 mm (15.75"), 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 range of supported coupling models and sizes enables direct integration with the machine’s spindle interface, thus eliminating the need to use a separate basic holder.
CoroBore BC insert-carrier solutions use CoroBore cartridges. Compared to fixed-insert pockets, this configuration is said to enable easy and efficient cartridge changes. The cartridges come in three configurations: radially and axially adjustable, axially adjustable only, and non-adjustable. All cartridge options are equipped with coolant nozzles capable of accommodating coolant pressure ranging to 80 bar (1,160 psi).
In addition to standard ISO inserts, CoroBore BC boring tools can be fitted with CoroBore 111 inserts, which come with optimized grade options for medium and rough boring. The Sandvik Coromant insert program offers productive geometries and grades for all types of materials and boring operations.
Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
