#CMT# #/CMT# The grinding machine (10) has a work-piece adapter (20) with a work-piece holder (22a,22b), where the work-piece adapter is designed to support or control the rotational driving of a rotatable work-piece (28). The grinding spindle sets (44,46) are displaced between a primary engagement position and a secondary engagement position. The former grinding spindle set is provided with a primary spindle (48) and a secondary spindle (52), while the latter grinding spindle set is provided with another primary spindle (50) and another secondary spindle (54). #CMT# : #/CMT# An independent claim is provided for a method for grinding of external surfaces of a work-piece on a grinding machine. #CMT#USE : #/CMT# Grinding machine for grinding of the external surfaces of a work-piece, particularly for outer circular- or non-circular grinding. #CMT#ADVANTAGE : #/CMT# The grinding spindle sets are displaced between a primary engagement position and a secondary engagement position, where the grinding spindle sets are provided with the primary spindles and the secondary spindles respectively, and thus ensures reduced idle-time of the grinding machines during the grinding and the feed movements of the work-piece in the longitudinal direction are reduced or avoided, and the design of the spindle sets allow a high flexibility during the displacement, while the reduced weight of the grinding wheel packet reduced the moment of inertia of the spindle sets to allow fast feeding movements of the work-piece, where the fiber composite body of the grinding wheel packet provides high thermal stability during grinding and a controlled collision free pivoting of the secondary spindles is allowed. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a grinding machine. 10 : Grinding machine 20 : Work-piece adapter 22a,22b : Work-piece holders 28 : Work-piece 44,46 : Spindle sets 48,50 : Primary spindles 52,54 : Secondary spindles #CMT#POLYMERS : #/CMT# The grinding wheel packet is comprised of a carrier body formed as a composite body, particularly a carbon fiber composite body. |
