BRUCKNER MECHANICAL FACE DRIVER CENTERS
SMM TYPE

Type SMM Mechanical Face Driver

Common Technical Features:

The Design - BRUCKNER aimed for minimum overhang and constrictions in the working area. Available with Morse taper or for flange-mounting for flanges to DIN.
VDS (Vibration Damping System) - The Vibration-damping element reduces vibrations occurring during operation resulting in: Longer life of driving pins and turning tools, and Improved workpiece surfaces due to smooth running
Constant Point of Reference - The high-speed steel driving pins are supported by a hardened sphere segment within the basic body: Advantages - Exact lengthwise turning, Out-of-square workpiece faces are compensated for, High operating safety
Easy Pin Change - The driving pins and the centerpoint can be taken out from the front. The flats on the sides of the pins enable the user to easily extract them with a screwdriver
Sping-loaded Centerpoint - Compensates for varying depth of centerbores
Concentricity Runout - Max. 0.02 mm
