The cross-cutting durability testing machine uses a needle-tipped cutting device. An automatic cross-cutting machine is capable of cutting coated surfaces in a grid pattern using the cross-cut method. Perpendicular blades are placed on the surface of the test sample and pressure is applied to cut. Test conditions are set so that all cuts reach the base material. After cutting, the sample is brushed, covered with tape, and peeled off within 5 minutes for evaluation. Model No. 551-AUTO-1 allows setting the number of cuts and distance via the touchscreen. Model No. 551-AUTO-2 adds a 90˚ automatic rotation function. Both models are more accurate than manual crosscutting machines.
