Rotary machining tool e.g. drill, for cutting e.g. solid wood, has walls including edges for channeling and orientating flows that drive dusts and chips during cutting, to collecting unit, and turbine arranged upstream of front part of body

摘要

#CMT# #/CMT# The tool (1) has a suction turbine (2) generating centrifugal airflows (35-37) during rotation with the tool. The airflows successively pass through an inlet opening (16) of a front wall (11) and over length of blades (10), and emerge via an annular peripheral outlet opening (28). The wall and a rear wall (12) have respective peripheral edges (17, 22) provided for channeling and orientating the airflows driving dusts and chips generated during cutting to a collecting unit of a machine tool. The turbine is arranged upstream of a front cutting part (5) of an axial/elongated cylindrical body (3). #CMT#USE : #/CMT# Rotary machining tool i.e. cutting tool e.g. drill or cutter, for cutting solid wood, agglomerated wood and metal, and assembled on a rotary drive shaft of a machine tool. #CMT#ADVANTAGE : #/CMT# The turbine is arranged in the upstream of the front cutting part of the cylindrical body, thus evacuating the produced dusts and chips from a working zone of the tool, in an optimal and efficient manner, and hence ensuring rapid and efficient holding of the dusts and chips, by the collecting unit of the machine tool. The design of the tool ensures better cutting quality of solid wood, agglomerated wood and metal, reduce usury of the tool and reduce soiling of the tool and rooms. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a suction turbine or cutting tool assembly. 1 : Rotary cutting tool 2 : Suction turbine 3 : Axial/elongated cylindrical body 5 : Front cutting part 10 : Blades 11 : Front wall 12 : Rear wall 16 : Inlet opening 17, 22 : Peripheral edges 28 : Annular peripheral outlet opening 35-37 : Centrifugal airflows.
