Abstract

A dedicated V-shaped groove forming machine comprises an X-axis slider dislosed over a plate material so as be movable in an X-axis (groove forming direction); a Z-axis slider supported by the X-axis slider so as to be movable in a Z-axis direction (vertical direction) ; and plural cutting tools mounted on the Z-axis slider; and a Y-axis carriage for moving a plate material (workpiece) in a Y-axis direction (perpendicular to the X-axis direction). Further, there are provided work table adjusting device for adjusting the cutting tool movement locus in parallel to the work table aria tool height detecting device determining an origin in the Z-axis direction, etc.

Claims12

Dependent claims

A groove forming machine for forming a V-shaped groove in a plate material, comprising:

a frame;
a guide rail mounted on the frame and extending along a first horizontal axis;
a slider mounted on the guide rail so as to be movable along the first horizontal axis;
a tool holder supported on the slider so as to be pivotal about a second horizontal axis which is perpendicular to the first horizontal axis, said tool holder being formed with a plurality of through holes, said tool holder being secured to the slider by a plurality of bolts, each bolt loosely passing through one of the through holes;
a plurality of cutting tools mounted on the tool holder so as to be arranged along the first horizontal axis;
at least one adjustment bolt having a free end, the adjustment bolt being mounted on the slider so that the free end thereof is vertically movable relative to the slider and is in contact with the tool holder;
and
means for detecting the presence or absence of the tool holder, said detecting means comprising a holder sensor mounted on the slider.
