Product Details

The Delem DAC-41 is a compact entry-level NC controller dedicated to hydraulic guillotine shears for sheet metal fabrication. This shear NC controller delivers reliable single-axis positioning control for the backgauge with incremental encoder feedback for repeatable cutting length. As a stable guillotine shear backgauge unit, it supports servo, single-speed and two-speed drive systems and adopts a straightforward numeric membrane keypad for fast operator setup. This sheet metal cutting controller is widely sourced as replacement spare part and retrofit upgrade for older hydraulic shearing machines, offering dependable positioning accuracy and low maintenance for sheet metal workshops.

Supported Functions

This shear NC controller supports manual jog movement, single cutting cycle and sequential automatic cutting. The guillotine shear backgauge unit provides backgauge retract, position preset, batch counter and inch / metric switching. It supports absolute and incremental positioning, travel limit setting and scale factor calibration. This sheet metal cutting controller also features built-in I/O signal checking and simple alarm indication for convenient on-site commissioning and fault diagnosis.

Core Functions

Precision encoder counting ensures consistent backgauge positioning for batch cutting tasks. The shear NC controller executes preset positioning sequences accurately and preserves all saved cutting recipes after power loss. It outputs interlock and drive signals to synchronize the complete shear cycle of hydraulic cutting equipment. Integrated fault detection helps technicians quickly identify encoder, wiring and signal faults to reduce unexpected machine downtime. Its standard panel cutout design allows direct swap for the original failed controller.
