390mm Outer Diameter Cr12MoV 38° Conveyor Belt Slitting Blade

As a professional precision blade manufacturer in North China, Xinzhe Blades develops industrial circular knives specifically for demanding conveyor belt processing applications. The 390mm Outer Diameter Cr12MoV 38° Conveyor Belt Slitting Blade is designed for longitudinal slitting of rubber conveyor belts, PVC belts, PU belts, canvas belts, nylon belts, and other flexible strip materials requiring stable cutting accuracy and excellent edge retention.

This conveyor belt slitting blade combines optimized toughness with controlled hardness, allowing it to maintain cutting sharpness while resisting edge chipping under high-frequency production conditions. It is widely selected by conveyor belt manufacturers, slitting machine OEMs, and industrial processing plants looking for reliable replacement circular knives.

Product Specifications

Core Technical Advantages

1.Premium Cr12MoV Tool Steel

Cr12MoV is widely recognized for its balanced wear resistance and toughness. For conveyor belt slitting applications where continuous friction and repeated impact occur, this alloy offers:

· Superior abrasion resistance

· Stable metallographic structure

· Excellent edge retention

· Reduced deformation during long production runs

This makes the 390mm Outer Diameter Cr12MoV 38° Conveyor Belt Slitting Blade highly suitable for industrial continuous slitting lines.

2.Optimized HRC38° Hardness

Many buyers assume higher hardness always means better performance. For flexible belt slitting, excessive hardness often causes:

· Edge brittleness

· Micro-chipping

· Premature cracking

The HRC38° heat treatment of this conveyor belt slitting blade is intentionally optimized for:

· Higher impact resistance

· Better flexibility under vibration

· Longer usable life

· Lower unexpected breakage risk

3.Precision Grinding for Clean Cuts

Every blade undergoes CNC precision grinding to ensure:

· Smooth edge finish

· Excellent flatness

· Stable blade rotation

· Burr-free slitting

This directly improves cut quality for rubber conveyor belt production.

4.Excellent Regrind Capability

The blade can be resharpened multiple times without compromising structural integrity, helping reduce total procurement cost.

Frequently Asked Questions

Q1: Why choose HRC38° instead of higher hardness?

For conveyor belt slitting, toughness is often more critical than extreme hardness. HRC38° prevents edge breakage under vibration and shock loading.

Q2: Can this blade fit non-standard slitting machines?

Yes. Xinzhe Blades offers full dimensional customization for OEM replacement requirements.

Q3: How many times can the blade be reground?

Under standard operation, the blade can typically be reground multiple times depending on cutting material and operating conditions.

Q4: How is blade quality verified?

Each conveyor belt slitting blade undergoes:

· Dimensional inspection

· Hardness testing

· Runout testing

· Surface finish verification
