The invention concerns a robot cell (1) comprising a multi axis robot arm (3), which terminates in a gripper (4) arranged to handle a pallet (2), and a sawing device (10), which is arranged to separate a nailed pallet part from a pallet (2) handled by said gripper (4). The sawing device (10) comprises a saw blade immersed in a liquid bath, which is contained in a trough (11) of the sawing device (10), such that separation of said nailed pallet part is performed in a liquid environment.

A machine tool includes a machining unit for feeding cutting oil to a work surface of a workpiece and machining the work surface, an optical sensor body unit dividing light outputted from a frequency sweep light source for outputting light whose frequency varies periodically into irradiation light with which the workpiece is to be irradiated and reference light, irradiating the workpiece with the irradiation light, detecting a peak frequency of interference light between reflected light which is irradiation light reflected by the workpiece, and the reference light, and measuring the distance from the machine tool to the work surface on the basis of the peak frequency, and a shape calculation unit calculating the shape of the workpiece on the basis of the distance measured by the optical sensor body unit.

A system 10 for processing work products 12 includes a housing 14 to contain the components of the system, which include a conveyor 16 for carrying the work products through the housing and past a work tool 18 being supported and moved relative to the conveyor by an X-Y actuator apparatus 20. A scanning system 21 is positioned in the housing 14 upstream of the X-Y actuator for ascertaining selected physical parameters of the work products so as to determine the manner in which the work tool 18 operates on the work products. The housing includes a compartment 22 in which is mounted a high-pressure pump system 23 to provide high pressure working fluid for the work tool 18. Also, a compact guard system 24 is positioned at the outlet 26 of the housing to prevent individuals from reaching into the housing from the exterior.

A robot cell (1) may include a multi axis robot arm (3), which terminates in a gripper (4) arranged to handle a pallet (2), and a sawing device (10), which is arranged to separate a nailed pallet part from a pallet (2) handled by said gripper (4). The sawing device (10) may include a saw blade immersed in a liquid bath, which is contained in a trough (11) of the sawing device (10). Such that separation of said nailed pallet part is performed in a liquid environment.

A grinding machine comprising a housing having a base for supporting the grinding machine, a shaft for holding a grindstone, a motor for rotating the shaft and a trough holder for holding a trough for grinding liquid, the through holder being arranged below the shaft, wherein the trough holder is movable in vertical direction between the base of the housing and the shaft for holding a grindstone and that the grinding machine comprises a lifting/lowering arrangement for moving the trough holder in said vertical direction.
