Industrial Robots

Industrial robots are multi-axis manipulators whose axes are driven by servo motors and which repeat a programmed motion with the same precision in every cycle. They are used in part handling, palletizing, machine feeding, assembly and pick-and-place jobs to do heavy or repetitive work with a constant cycle time. This category includes a GMT branded 6-axis articulated robot with a 220 kg load capacity and 2705 mm reach, and a 4-axis SCARA robot with a 6 kg capacity and 600 mm reach. The six-axis structure orients the tool at any desired angle; the SCARA performs fast positioning in the horizontal plane and linear motion on the vertical axis. Choose the load capacity, reach, number of axes, repeatability and axis speeds according to the part to be handled, the gripper weight and the targeted cycle time. The product data lists repeatability values of ±0.02 mm and ±0.06 mm; the gripper and tool weight are included in the load capacity. A SCARA robot does not replace a six-axis articulated robot; because it rotates the tool only around the vertical axis, it cannot orient the part at oblique angles.
