The TFG Gauging Block (System 52) is a precision calibration essential engineered for the rapid alignment and coordinate setting of your zero-point workholding. Specifically designed for the System 52 grid (Ø16mm studs), this block provides a master reference point to “clock in” your machine’s spindle with absolute certainty. While many setup tools are lightweight, the TFG Gauging Block is crafted from solid, precision-ground tool steel, offering a stable and rigid surface for probing or indicator work. Its compact 75x75mm profile is uniquely optimized for high-precision 5-axis environments where space is tight but accuracy is non-negotiable. With a repeatability of ≤ 0.005mm, it is the ideal tool for ensuring your workholding offsets are dead-on, making it a must-have for medical, aerospace, and high-tolerance job shops.
