1-2-3 Blocks are precision measuring tools used in machining and manufacturing operations to accurately position and hold workpieces. They are typically made of hardened steel and are square in shape, with each side measuring 1 inch by 2 inches by 3 inches, hence the name "1-2-3 Block".
1-2-3 Blocks are commonly used in conjunction with other measuring tools, such as dial indicators or height gauges, to accurately measure and position workpieces during machining operations. They can also be used to provide support and stability to workpieces during drilling, milling, and grinding operations.
The flat and parallel surfaces of 1-2-3 Blocks are precision-ground to within a few microns, making them highly accurate and reliable for positioning and measuring purposes. They often have threaded holes or T-slots on their surfaces to allow for easy mounting and positioning.
Overall, 1-2-3 Blocks are an essential tool in precision machining and manufacturing, helping to ensure that workpieces are positioned accurately and securely during the machining process.
