Outer Diameter 390 CR12MOV Two-stage Circular Cutter

The Outer Diameter 390 CR12MOV Two-stage Circular Cutter is a high-precision shoulder-type circular slitting blade specifically developed for medium-thickness metal coil processing and industrial strip cutting. Manufactured by Xinzhe Blades using forged Cr12MoV alloy tool steel, this two-stage circular cutter is optimized for high-speed slitting lines requiring precise axial positioning, superior rigidity, and long-term cutting consistency.

The reinforced two-stage locating structure enhances blade stability during continuous operation, minimizing lateral movement and ensuring highly consistent strip width. It is widely used in steel strip slitting, aluminum coil processing, copper foil cutting, laminated metal slitting, rubber sheet processing, and paper-plastic composite material conversion.

As a professional circular cutter manufacturer in China, Xinzhe Blades combines precision CNC machining, integrated heat treatment, cryogenic processing, and strict quality inspection to ensure every Outer Diameter 390 CR12MOV Two-stage Circular Cutter meets industrial-grade performance standards.

Technical Specifications

Key Features

1.Premium Forged Cr12MoV Material

The blade is produced from high-carbon high-chromium Cr12MoV alloy steel, known for:

• Excellent wear resistance

• Strong impact toughness

• High hardness retention

• Superior thermal stability

This material performs exceptionally well in continuous high-speed slitting operations where ordinary carbon steel blades fail prematurely.

2.Precision Two-stage Positioning Structure

The defining feature of this Outer Diameter 390 CR12MOV Two-stage Circular Cutter is its double-shoulder locating design.

Advantages include:

• Accurate axial positioning

• Enhanced anti-shift performance

• Even load distribution

• Reduced vibration during rotation

This structure is particularly valuable for buyers operating precision slitting lines requiring strict strip width tolerance.

3.Burr-free High-Precision Cutting

Each blade undergoes:

• CNC rough machining

• Fine surface grinding

• End-face precision finishing

• Static balancing inspection

The result is smooth cutting edges with:

• Minimal burr formation

• No edge collapse

• No indentation marks

• Consistent slit surface quality

4.Longer Service Life

Compared with conventional carbon steel circular cutters, the service life of this CR12MOV circular cutter is typically extended by 3–5 times under comparable working conditions.

This reduces:

• Blade replacement frequency

• Machine downtime

• Maintenance labor costs

Applications

Metal coil processing: Slitting of cold-rolled steel strip, stainless steel strip, aluminum strip, copper strip, and galvanized sheet

Rubber, plastics, and leather: Slitting of rubber sheets, leather, conveyor belts, and hard plastics

Packaging and paper-plastic products: Precision slitting of laminating materials, insulating paper, and composite boards

Frequently Asked Questions

Q1: What material is best for heavy-duty slitting applications?

Cr12MoV is one of the most reliable materials for medium-to-heavy industrial slitting due to its excellent hardness, wear resistance, and toughness balance.

Q2: Can Xinzhe Blades customize dimensions?

Yes. We provide OEM customization for:

• Inner diameter

• Thickness

• Shoulder height

• Edge angle

• Surface finish

Custom manufacturing is available based on machine shaft size and slitting conditions.

Q3: How long is the service life?

Under standard metal coil slitting conditions, the blade generally performs 3–5 times longer than standard carbon steel alternatives.

Actual service life depends on:

• Material hardness

• Cutting speed

• Cooling conditions

• Operator maintenance

Q4: Can the blade be re-sharpened?

Yes. The Outer Diameter 390 CR12MOV Two-stage Circular Cutter supports multiple precision regrinding cycles while maintaining dimensional stability.

Selection Recommendations

For optimal performance, buyers should provide:

• Shaft diameter

• Material type

• Material thickness

• Cutting speed

• Required slit width tolerance
