Abstract
A sampling device for removing a surface portion from a substrate. The device includes a frame structure and a cutter head assembly. The cutter head assembly includes a pivot body having a first end supported at a pivot point on the frame structure, and a cutter supported for rotation about a rotational axis at a second end of the pivot body. The cutter has a semi-ellipsoidal shape and a drive motor is operably connected to the cutter. The pivot point is located in spaced relation to the rotational axis. The cutter is operable to cut a surface portion of a substrate during pivotal movement about the pivot point.
Claims19
A sampling device for removing a surface portion from a substrate, the device comprising:
- a frame structure;
- a cutter head assembly comprising:
- a pivot body having a first end supported at a pivot point on said frame structure;
- a cutter supported for rotation about a rotational axis at a second end of said pivot body, said cutter comprising a shape defined by a rotation of a conic having a circular cutting end;
- a drive motor operably connected to said cutter;
- and
- said pivot point located in spaced relation to said rotational axis, and said cutter being operable to cut a surface portion of a substrate during pivotal movement about said pivot point.
A sampling device for removing a surface portion from a substrate, the device comprising:
- a frame structure including a base side;
- a cutter mechanism including a cutter movable in a vertical direction to extend from said base side into engagement with said substrate;
- a plurality of height adjusting members extending from said base side to engage said substrate, said height adjusting members being movable relative to said frame structure and relative to said cutter to define an adjustable predetermined depth for said cutter to penetrate said substrate;
- and
- a plurality of clamp members comprising magnets mounted to said frame structure for engagement with said substrate to retain said frame structure at predetermined height positions relative to said substrate, as defined by said height adjusting members.
