Since its formation in 1991 subcontract component broaching has been at the core of NBS's business.
NBS has, over the years, built up a vast stock of broaching tools and can now boast to having in access of 1400 broaching tools, one of the largest stocks within the United Kingdom.
With our vast range of broaching tools/fixtures, together with eight broaching machines, we can undertake any broaching operation (internal or surface). An example is where we broach keyways from as little as a 2mm (0.080 in.) key in a 8mm (.315 in.) bore up to an involuted spine broach in excess of 12.7 cm (5 in.) diameter.
Also, using our 150 ton press we can produce taper splines, an example being steering arms for the automotive industry.
We also have the facility to produce spiral/ helical internal forms.
NBS is also one of a small number of companies who broach materials other then steel. for example, we carry out broaching on Tufnil, Plastic, and industrial nylon.
