Back Gauge (Shearing)
A programmable stop system on the shear that positions the sheet for precise, repeatable cuts. The CNC controller drives the back gauge to programmed positions, enabling multiple accurate cuts from a single sheet with minimal operator intervention.
The back gauge is a critical positioning system that allows CNC shears to repeat cuts with exceptional accuracy across multiple blanks. By automatically moving to programmed positions, operators can eliminate manual measuring and repositioning, significantly reducing setup time and operator error.
For example, a shop shearing multiple 12-inch blanks followed by 8-inch blanks can program both dimensions and execute the sequence without stopping between cuts. This automation is especially valuable in CNC shearing operations where high-volume, high-precision runs demand consistent dimensions.
Proper back gauge calibration and maintenance directly impact the tolerance and squareness of finished blanks, making it a foundational component for achieving near-net-shape results.
