Product Overview
Precision 90° Corner Notches. One Hit. Every Time.
The KAVDO Fixed Angle Notching Machine delivers clean, burr-free 90° corner notches in a single stroke. The rigid frame, precision-ground blade set and hydraulic drive system produce consistent notch quality from the first cut to the ten-thousandth — with no blade deflection, no distortion and minimal deburring required.

- 20 MPa hydraulic system with 30 strokes per minute
- Max notch length up to 250 mm (QF28Y-6*250)
- Large worktable up to 750×750 mm at 850 mm working height
- Compact footprint — smallest model only 550×550×1100 mm
Performance Highlights
Key Advantages
20 MPa hydraulic power, precision-ground blades and a rigid steel frame — delivering clean, accurate 90° corner notches on sheets up to 6 mm thick at 30 strokes per minute with minimal operator effort.
Single-Stroke Notching
One stroke removes the full corner notch cleanly. No nibbling, no secondary cuts. The hydraulic ram delivers the full notching force in a single, controlled downstroke for maximum productivity and edge quality.
Precision-Ground Blade Set
D2 tool steel blades hardened to HRC 58–62, precision-ground to tight clearance tolerances. The fixed 90° blade geometry produces clean, square notch corners with minimal burr — no deburring required on most materials.
Heavy-Duty Rigid Frame
Welded and stress-relieved steel frame with precision-machined guide surfaces ensures zero deflection under full load. The rigid construction maintains blade alignment and notch accuracy throughout the machine’s lifetime.
Adjustable Blade Clearance
Fine-adjust blade gap to match material thickness from 0.5 to 6 mm. Proper clearance ensures clean shearing with minimal burr, extending blade life and producing bend-ready notch edges on every material type.
Built-In Safety Features
Hydraulic hold-down clamp secures the workpiece before the blade engages. Two-hand operation, light curtains and emergency stop provide full operator protection. CE-compliant safety system meets international standards.
Low Operating Cost
No consumables, no gas, no laser optics. D2 blades last 20,000+ cycles between regrinding. Simple hydraulic system with minimal maintenance. One of the lowest cost-per-notch solutions on the market.
Not Sure Which Notch Size You Need?
Our application engineers will review your sheet sizes, material types and box dimensions to recommend the optimal notching machine capacity — ensuring clean corners and perfect bends every time.

Core Components
Machine Structure
Robust hydraulic notching system with precision-ground blades, adjustable clearance and integrated safety — built for years of reliable, high-throughput corner notching production.
-
1
Welded Steel Frame
Heavy-duty welded and stress-relieved steel construction with CNC-machined guide surfaces for permanent geometric accuracy and zero frame deflection.
-
2
Hydraulic Power Unit
Compact hydraulic system with high-efficiency pump, pressure relief valve and oil cooler delivers consistent notching force with low noise and smooth operation.
-
3
Precision Upper Blade
90° V-shaped upper blade in D2 tool steel (HRC 58–62) with four cutting edges. Rotate for fresh edge — quadruples blade life between regrinding.
-
4
Fixed Lower Blade Set
Precision-ground lower blade pair mounted at 90° with adjustable gap. Fine-tune clearance to material thickness for clean, burr-free notch edges.
-
5
Hydraulic Hold-Down Clamp
Automatic hold-down clamp presses the sheet firmly before the blade engages, preventing sheet movement and ensuring square, distortion-free notch corners.
-
6
Backstop & Scale System
Adjustable backstop with graduated scale allows rapid positioning for repeatable notch depth. Optional digital readout for precision depth setting.
How It Works
4-Step Notching Workflow
From sheet positioning to bend-ready notched corners — a fast, repeatable process that takes seconds per notch with minimal operator skill required.
1
Set Backstop
Adjust the backstop to the required notch depth using the graduated scale or optional digital readout. Set blade clearance for your material thickness. Lock settings for batch production.
2
Position Sheet
Slide the sheet corner into the machine throat until it contacts the backstop. Align the sheet edge against the guide fence for a square, precise notch position.
3
Notch & Cut
Activate the hydraulic stroke via foot pedal or two-hand control. The hold-down clamp secures the sheet, then the upper blade descends to remove the corner notch in a single, clean stroke.
4
Remove & Bend
Slide the notched sheet out. The clean 90° corner is ready for immediate bending on a press brake or box-and-pan brake — no deburring, no filing, no secondary operations.
