What do you need to know about the performance and durability of the CT-2300 Manual Cut-off Machine?

The CT-2300 Manual Cut-off Machine is a widely used precision cut-off machine designed for metallurgical lab machinery and material testing lab equipment. Its performance and durability make it suitable for sample preparation equipment, failure analysis lab equipment, and foundry quality control equipment.

What is the maximum cutting capacity of the CT-2300 cutting machine?

The CT-2300 Manual Cut-off Machine serves as essential sample preparation equipment across various industries, particularly in metallurgical lab machinery and material testing lab equipment. Its cutting capacity fundamentally determines its suitability for different applications, making this a critical performance parameter for potential users.

Material-Specific Cutting Performance

As a precision cut-off machine, the CT-2300 demonstrates varying capabilities depending on material properties:

• Ferrous Metals (e.g., steel, cast iron):
  The machine reliably sections samples up to 50mm in diameter when using appropriate aluminum oxide or silicon carbide wheels. The wet abrasive cut-off machine design prevents thermal distortion, preserving sample integrity for subsequent metallographic analysis.

• Non-Ferrous Metals (e.g., aluminum, copper):
  Softer materials permit slightly larger diameters (up to 65mm) due to reduced cutting resistance. However, operators must select finer-grit wheels to prevent material smearing during manual sample preparation.

• Hard Materials (e.g., ceramics, carbides):
  Diamond-embedded cutting wheels are mandatory for these applications. While maximum diameter decreases to 40mm for tungsten carbide, the hard material cutting tool maintains exceptional cut quality without micro-fracturing.

Cutting Wheel Selection Guide

Proper wheel choice directly impacts the CT-2300 cutting machine’s capacity:

Operational Considerations for Maximum Capacity

1. Coolant System Optimization
   The laboratory abrasive cutting machine’s integrated coolant system must maintain consistent flow during operation. Insufficient coolant leads to:

   • Premature wheel wear
   • Heat-affected zones in samples
   • Reduced effective cutting capacity

2. Feed Pressure Management
   Excessive manual force does not increase capacity; instead, it:

   • Accelerates wheel degradation
   • Risks sample deformation
   • May trigger safety shutdowns in advanced models

3. Machine Setup Verification
   Prior to cutting near capacity limits:

   • Confirm spindle runout is within 0.05mm
   • Ensure vise alignment parallels the cutting plane
   • Verify wheel flange tightness to prevent slippage

Real-World Application Examples

• Foundry Quality Control Equipment applications typically process 30-40mm cast iron samples for microstructure analysis.
• Failure Analysis Lab Equipment setups frequently section 25-35mm fracture specimens from hardened steel components.
• Metal Testing Laboratory Tools often handle 50mm diameter aluminum test coupons for mechanical property evaluation.

The CT-2300 manual abrasive cutter demonstrates consistent performance across these scenarios when operated within specified parameters. Its versatility as industrial material sectioning equipment stems from this balanced combination of capacity and precision.
