Abstract

Selecting the right Metallographic Cutting Machine depends on your material hardness, sample size, required edge integrity, and daily sample throughput.

Key Takeaways

· A precision cut-off machine must match your sample size, material hardness, and required edge quality.

· The counterweight sliding loading system minimizes cutting force and heat damage to sensitive materials.

· 0.01 mm positioning accuracy ensures repeatable cut positions and minimal material waste.

· Automatic coolant circulation protects both the sample and the diamond cutting wheel.

· A full range of clamps (single saddle, double saddle, teardrop, flat, irregular) handles diverse sample shapes.

 

Understanding Metallographic Precision Cutting

In metallographic sample preparation, the cutting stage is the first critical step. A poorly chosen cut-off machine can introduce heat damage, work hardening, or deformation that ruins the microstructure before polishing even begins.

Application & Materials

· Hardened steels: tools, dies, gears, bearings, welded joints

· Non-ferrous metals: aluminum, copper, brass, titanium alloys

· Brittle materials: ceramics, hard alloys, electronic circuit boards, glass

· Irregular shapes: tubes, rods, plates, castings, small components

· Cutting accuracy: 0.01 mm positioning, suitable for both rough and precision cuts

Compliant with metallographic sample preparation standards including ASTM E3 and GB/T 15824. Ideal for laboratories preparing samples for grinding, polishing, and microscopic examination.

Mechanical Structure & Cutting Advantage

· Enclosed transparent protective cover with safety interlock switch — protects operator during cutting

· Counterweight sliding loading system: smooth, controllable feed that minimizes sample damage and chatter

· Closed-loop cutting control: monitors load in real time, prevents overload from burning out motor or circuitry

· Automatic stop when cutting is complete — no need to monitor the machine continuously

· Brushless DC motor: 125 W, speed adjustable 0–1500 r/min, long service life, no brush replacement

· Automatic coolant circulation: the rotating cutting wheel drives coolant flow from the tank, flushing the cut zone continuously

· Standard 6-inch (150 × 12.7 × 0.43 mm) cutting wheel; optional 4-inch, 5-inch, and 7-inch diamond/resin wheels

· Cutting positioning accuracy: 0.01 mm for repeatable and precise cuts

Total Cost of Ownership (TCO)

·  Brushless motor eliminates brush replacement cost

·  Closed-loop control prevents motor burnout — reduces repair cost

·  Standard clamp set covers most sample shapes — minimizes extra tooling purchase

·  Low coolant consumption with automatic circulation — economical daily operation

Certification & Standards

·  CE certified; ISO 9001 quality management system

·  Compliant with ASTM E3 and GB/T 15824 metallographic sample preparation requirements

·  Suitable for third-party laboratory inspection and quality control use

Frequently Asked Questions (FAQ)

1. Why choose the CUT-15ZD precision cutting machine?

It features low-speed brushless operation, closed-loop overload protection, counterweight feeding, 0.01 mm positioning accuracy, automatic coolant circulation, and a complete set of clamps. It minimizes heat damage and sample deformation compared to high-speed saws.

 

2. What materials can it cut?

It handles hardened steels, non-ferrous metals, carbides, ceramics, glass, and electronic circuit boards. Different cutting wheels (diamond for hard/brittle materials, resin for soft metals) are available as options.

 

3. What size cutting wheel does it use?

The standard wheel is 6 inch (150 × 12.7 × 0.43 mm). Optional 4-inch, 5-inch, and 7-inch DCWA series diamond wheels are available for different sample sizes and material types.

 

4. How does the safety system work?

The machine has a transparent enclosed guard with a safety interlock — cutting stops immediately if the cover is opened. An emergency stop button provides instant shutdown in any situation.

 

5. What is the warranty?

The whole machine has a 12-month warranty. KASON provides lifetime technical support and supplies matching consumables (cutting discs, coolant, clamps) on an ongoing basis.
