sheet metalguillotineCNC

Overview
This model of the KMT RNC series is a motorized guillotine shear designed for precision plate cutting in industrial production. It combines a rigid welded steel frame, sliding-block guided cutter bar and a low cutting angle to minimise part distortion. The kerf is manually adjustable and the rear stop is NC-controlled; an integrated Return-to-Operator function improves handling of short offcuts.

Highlights

• Welded steel frame with sliding-block guide for the cutter bar
• NC-controlled rear gauge with easy programming
• Automatic, semi-automatic and manual operating modes
• Standard cutters for stainless steel processing; reversible upper blades and multi-edge lower blades
• Manually adjustable kerf
• Return-to-Operator automatic return function for cut sections

Machine Frame

• Very rigid, fully welded steel construction with precision sliding-block guidance for clean, repeatable cuts
• Special cutters included for stainless steel; upper cutters reversible, lower cutters with four cutting edges
• Continuous rigid hold-down secures the sheet immediately ahead of the cut line
• Manual kerf adjustment to set optimum clearance for different materials

Ergonomic Design

• Automatic return-to-operator function sends short cut pieces back to the operator position to increase throughput and safety
• Rigid side angle stop simplifies perpendicular alignment of plates to the cut line
• Robust support arms secure large plates during cutting
• Material support rollers recessed into the work table to ease handling and reduce scratches
• Mobile foot switch frees both hands for workpiece handling
• Bright LED cut-line illumination creates a visible shadow for accurate marking
