Provided is a disclosure for a cutting device configured to control a linear speed of a cutting wheel as the cutting wheel gets smaller with use. In one example, the cutting device includes a cutting wheel; an actuator to rotate the cutting wheel; a power source configured to provide power to the actuator for rotating the cutting wheel at an adjustable rotational velocity; and control circuitry configured to adjust the rotational velocity of the cutting wheel to maintain a substantially constant surface speed.

Method and apparatus for maintaining a surface speed of a circular cutting device

A sample preparation saw has a base, a housing, a saw assembly mounted to the base, a dressing assembly, a sample clamping assembly mounted to the base, and a reservoir assembly. The saw assembly includes a blade assembly with a rotating blade. The blade assembly is movable along x-, y- and z-axes by at least two drives. The dressing assembly is operable to dress the rotating blade. The sample clamping assembly includes a rail, a sample mount removably positioned on the rail and a saddle operable to hold a sample. The reservoir assembly is operable to recirculate a rinse fluid sprayed on the rotating blade, and includes a basin having a pump and a series of weirs.

Provided is a disclosure for a cutting device configured to control a linear speed of a cutting wheel as the cutting wheel gets smaller with use.

A material removal system may control movement of a material removal machine based on whether a material removal tool is in contact with a sample. A material removal system may include a material removal machine (e.g., saw, grinder, polisher, and/or more general material preparation and/or testing machine) that is configured to move at the urging of one or more actuators. The system may further include control circuitry configured to control movement (and/or speed, acceleration, etc.) of the material removal machine (e.g., via the actuators) based on one or more power, thermal, position, and/or other parameters that indicate whether the material removal tool of the material removal machine is in contact with a sample.
