<p>#CMT# #/CMT# The device (1) has support points i.e. casters mounted on stem and fixed on a rear part i.e. base of the device. The support points form a complete system when a hand grinder/polisher (4) is fixed on the device. One of the support points is a reference support point i.e. surfacing tool, fixed on a head of the grinder or polisher. A balance beam (15) pivots on an axle (20) so as to be abutted against back of the grinder or polisher. Position of the beam is fixed by using a tightening system. #CMT#USE : #/CMT# Device for supporting sandpapers made of hard ground e.g. concrete, marble, natural stone, wood and steel, to position a hand grinder/polisher or surfacing apparatus in a planar manner. #CMT#ADVANTAGE : #/CMT# The device realizes planar positioning of the hand grinder/polisher or surfacing apparatus in a quick and accurate manner without using tools. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a rear view of a support device. 1 : Support device 4 : Hand grinder or polisher 15 : Balance beam 16 : Plate 20 : Axle.</p> |
