8 High Performance Live Centres BRUCKNER WORKS STANDARD Test report for concentricity accuracy Every single BRUCKNER high performance live centre is tested for its runout under axial load. The test result is stamped into the high performance centre and is guaranteed by the test report. BRUCKNER WORKS STANDARD Our high performance live centres – standard as well as special designs – are produced and tested according to our works standard. Materials, production and testing are subject to strict quality guidelines guaranteeing function and performance of our tools. Tolerance of taper shank The Morse taper is ground according to DIN 228 AT4 (gauge accuracy). This fine tolerance guarantees a close fit of the high performance centre in the tailstock and therefore the full utilisation of the concentricity accuracy. Precision bearings The bearing seats in the housing and on the centrepoint are precision-ground. The bearings and their seats are selected to fit. Result: high stability, concentricity and long life. Load values The load values given in our tables are calculated with the world wide acknowledged software KISSsoft. When used in keeping with currently valid standards DIN and ISO, this software guarantees a safe and reliable load calculation. Centrepoint The centrepoint is of through-hardened alloy tool steel resistant to wear. Housing The housing is of alloy tool steel with high tensile strength. Housing head and shank are case-hardened for protection from damage. Maintenance The bearings are maintenance-free due to permanent lubrication. Repair service Our repair service is at your disposal for any repairs. We judge the tool’s condition and inform you about the extent of necessary repairs.
