HONING & GRINDING
At F & J Bushings we have in place the facilities to finish the internal and/or external diameters to a tolerance specified by the customer.
*Our Sunnen honing machines are purpose built machines which can internally hone a finish to the customers specifications.
*Honing sizes range from 1.5mm diameter right through to 75mm.
*We use a variety of different honing stones to suit the type of material being honed and the required finish.
*Honing produces greater accuracy and a finer surface finish than internal grinding,and provides a stress-free base metal surface in the bore.
*We can achieve tolerances as low as +/-0.002mm
