Abstract
Abstract A scalping machine with a nonrotatable workpiece which is fed through a revolving cutter head in which the cutters are not only adjustable in radial directions relative to the workpiece but also so as to vary the angle of their cutting edges relative to a plane extending at right angles to the axis of the workpiece.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
In a scalping machine having means for clamping a substantially cylindrical workpiece in a nonrotatable position and for feeding said workpiece in its axial direction, a rotary cutter head adapted to revolve about said workpiece during the feeding movement thereof, a plurality of cutters mounted in said cutter head in a spokelike arrangement relative to said workpiece and rotatable with said cutter head, and means for adjusting said cutters in radial directions relative to said workpiece, the improvement comprising further adjusting means for varying the blade angle of all of said cutters relative to a plane extending at right angles to the axis of said workpiece.
Claim 2
Dependent Claim
106 words
In a scalping machine having means for clamping a substantially cylindrical workpiece in a nonrotatable position and for feeding said workpiece in its axial direction, a rotary cutter head adapted to revolve about said workpiece during the feeding movement thereof, a plurality of cutters mounted in said cutter head in a spokelike arrangement relative to said workpiece and rotatable with said cutter head, and means for adjusting said cutters in radial directions relative to said workpiece, the improvement comprising further adjusting means for varying the blade angle of all of said cutters relative to a plane extending at right angles to the axis of said workpiece.
Claim 3
Dependent Claim
128 words
A scalping machine as defined in claim 1, in which each of said cutters is secured to the inner end of a tool holder, means for mounting each of said tool holders in said cutter head so as to be rotatable about its own axis relative to said cutter head and said workpiece, said blade-angle adjusting means comprising pinion means rigidly secured to each of said tool holders and having teeth extending radially to the axis of said tool holder, common gear means meshing with all of said pinion means, and means for turning said common gear means so as to turn simultaneously all of said tool holders about their axes and for thereby also turning all of said cutters so as to vary the blade angle thereof.
Claim 4
Dependent Claim
31 words
A scalping machine as defined in claim 1, in which at least a part of the length of the cutting edge of each of said cutters has a substantially concave shape.
Claim 5
Dependent Claim
31 words
A scalping machine as defined in claim 3, in which said substantially concave part of said cutting edge has a curvature dependent upon the diameter of the workpiece to be scalped.
Claim 6
Dependent Claim
21 words
A scalping machine as defined in claim 1, further comprising a scalping nozzle separate from and located behind said cutter head.
Claim 7
Dependent Claim
34 words
A scalping machine as defined in claim 5, in which said scalping nozzle is mounted in a nonrotatable position and has an annular cutting edge disposed closely behind the rear sides of said cutters.
Claim 8
Dependent Claim
40 words
A scalping machine as defined in claim 5, in which a part of said scalping nozzle is at least in indirect engagement with said cutters for bracing the same in a direction substantially parallel to the axis of said workpiece.
Claim 9
Dependent Claim
21 words
A scalping machine as defined in claim 5, further comprising means for controlling and varying the temperature of said scalping nozzle.
