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.

Sample preparation saw

Apparatus, systems, and/or methods for filtering, recapture, and/or recirculation of coolant are disclosed. In some examples, coolant (e.g., coolant fluid) is used to cool and/or clean a machine, such as a material removal machine, for example. In some examples, a recirculation tank may be in fluid communication with an inlet and/or outlet of a cabinet (and/or housing) of the machine. The recirculation tank may include a recapture reservoir having a filtering surface configured to prevent particulates, debris, and/or swarf from being recirculated with the coolant. A vibration device (e.g., a vibration motor and/or vibrating actuator), may be in contact with and/or configured to vibrate (and/or shake, rattle, oscillate, etc.) the filtering surface, recapture reservoir, and/or recirculation tank so as to keep the filter free from obstruction and/or help settle and/or compact filtered particulates in a bottom of the recapture reservoir and/or recirculation tank.

Machine tool with recirculating coolant filtration system

Apparatus, assemblies, and/or systems related to material removal are disclosed, such as saws, grinders, polishers, and/or more general material preparation and/or testing machines, for example. A material removal system may include a material removal machine that is configured to move via a material removal assembly. The material removal machine also includes a material removal tool configured to spin on a spindle at the urging of a tool actuator. The tool actuator is integrated into the material removal machine, such that the tool actuator moves along with the material removal machine.

Compact material removal machines

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.

Apparatus, systems, and/or methods for adjusting belt tension in a material removal machine are disclosed. In some examples, the material removal machine includes a material removal tool secured on a spindle. A spindle pulley may be secured to the spindle, such that rotation of the spindle pulley causes the material removal tool to be rotated via the spindle. The material removal machine may further include a movable hub that retains the spindle, such that movement of the hub translated into movement of the spindle. Because the spindle pulley is securely attached to the spindle, movement of the hub may translate into movement of the spindle pulley. This movement of the spindle pulley may change a distance between the spindle pulley and an actuator pulley, thereby changing the tension in a belt connecting the spindle pulley and the actuator pulley.
