Description

Axyz Bt-562090 B2031l-90 Kf2-70 Double Edge Flat Point Cutting Knife Blades

Axyz BT-562090(or B2031L-90) is a high-quality Tungsten Carbide double-edged flat-head CNC vibratory insert.It is primarily designed for use on AXYZ CNC engraving machines (CNC routers) and CNC cutting machines equipped with vibrating tool systems. Thanks to the use of high-hardness tungsten steel/carbide material, this blade possesses exceptional wear resistance and an extremely long cutting life.

Diameter of the holder: 6 mm
Knife hight: 106 mm
Max. cutting depth: 90 mm
Knife type: Oscillating
Angle: 2 x 30°
equivalent to: MultiCam 84-00193-BT-562090, AXYZ B2031L-90

Main materials used

The blade's 90mm depth of cut makes it ideal for heavy-duty and deep cutting on vibratory cutter heads . Commonly machined materials include:

Various foam materials : EVA foam, polyethylene (PE) foam, rigid foam board, PU sponge
Packaging and Paper Products : Corrugated Board, Honeycomb Board, Thick Cardboard
Flexible materials : thick leather, rubber, felt, gasket materials

How to correctly select and use Axyz BT-56240 BT-56265 BT-56270 BT-562090 Double Edge Flat Point Carbide Knife Blades

Selecting and using Axyz BT-562xx series (B2031L family) double-edge flat-point carbide knife blades involves aligning the cut length with material thickness and managing feed rates to prevent stress on the carbide shaft. Here’s a guide to help you through the process:

Step 1: Selecting the Correct Blade
Choose a blade with the shortest cut length that covers your material's thickness plus a 1–2 mm safety margin. Excessive blade length results in higher leverage forces and blade deflection.
- BT-56240 (40 mm Cut Depth): Suitable for rubber gaskets, dense acoustic felt, corrugated plastics, and foam blocks up to 38 mm thick. Offers maximum lateral rigidity.
- BT-56265 & BT-56270 (65 mm & 70 mm Cut Depth): Ideal for medium to thick packaging foam (EPE/EVA), soundproofing mats, and layered composites.
- BT-56290 (90 mm Cut Depth): Designed for deep EPS foam block conversion, thick polyurethane foam, and bulk insulation material.

Step 2: Machine Setup & Installation
Proper seating is crucial to minimize vibration and avoid premature chipping or snapping.
1. Clean the Shank and Collet: Use isopropyl alcohol to clean the 6 mm shank and toolholder sleeve. Residual resin or metal dust can cause misalignment, leading to micro-fractures from oscillation loads.
2. Mount and Secure the Tool: Fully insert the 6 mm shank into the toolholder. Torque the clamping screw or collet nut as specified, avoiding over-tightening to protect the tungsten carbide.
3. Set Z-Axis Surface and Bottom Clearance: Calibrate the Z-axis zero at the top of the sacrificial cutting mat. Ensure the flat tip just grazes the mat surface (0.1–0.2 mm clearance) at its lowest stroke.
4. Configure Controller Parameters: Adjust your controller (e.g., Axyz A2MC) to detect the double-edge profile. Enable tangential knife control and set lifting parameters for sharp corners.

Step 3: Operational Best Practices
To optimize operations, consider the following practices:
- Maximize Oscillation Rate: Operate at high-frequency oscillation (10,000–12,000 RPM) for smooth slicing without dragging dense materials.
- Utilize Bidirectional Advantage: The double edges on sweeping curves allow high-speed continuous toolpaths without needing full 180° turns.
- Ensure Proper Cornering & Lift-and-Turn Rules: For turns under 45 degrees, continuous slicing is feasible. For sharp 90-degree corners on materials thicker than 20 mm, perform a tangential lift-and-turn to avoid shaft snapping.
- Manage Feed Rates:
- Foams (EPS / EPE): Employ a high feed rate (8–15 m/min) at full RPM.
- Dense Rubber / Gaskets: Use a lower feed rate (2–5 m/min) with high oscillation to minimize lateral drag.
