Abrasive Cutting Disc Metallographic Sample Cutting Machine for Round Bars

The QG-3A Manual Metallographic Cutter is designed for precise cutting of challenging materials like rocks, ceramics, and metals (max Φ50mm). Its manual swing-arm feeding system allows full control over cutting speed, while the integrated cooling path prevents sample overheating. CE/ISO9001 certified and built with a transparent safety cover, it’s the go-to equipment for labs prioritizing safety and versatility.  

Why QG - 3A Stands Out

1. Manual Swing Arm Control: Allows for on - the - fly adjustment of cutting speed for brittle materials.
2. Anti - Overheating Cooling System: Features dual water paths and adjustable coolant flow.
3. V - Slot Clamp & Safety Cover: Secures irregular samples and protects operators.
4. Diamond Disc Ready: Can cut hard ceramics and rocks effortlessly.
5. Compact Lab Design (580×560×680mm): Fits well in tight workspaces.

 ==‌FAQ‌==

• ==‌Q: Can I use the QG-3A for zirconia ceramic samples?‌==
  A: Yes! Switch to a diamond cutting disc and reduce feeding speed.

• ==‌Q: How to clean the coolant tank?‌==
  A: Drain and rinse monthly – the stainless steel tank resists corrosion.

• ==‌Q: Is training provided?‌==
  A: Free video manual + lifetime email support included.

QG-3A Metallographic Sample Cutting Machine is suitable for the cutting of general metallographic and lithofacies sample materials. It is equipped with cooling path and switch, which can take away the heat of cutting by the prepared cooling liquid to avoid burning the sample. The machine operates easily and safely, is the ideal equipment in the metallographic laboratory. The spindle of the cutting disc is fitted on the rocker arm bearing seat, which is driven by the V-belt pulley. The feeding speed is determined by the speed of manual arm swing. Above the working table is the specimen quick clamp device. Pressure bar can move up and down, clamp and use easily. There is cooling liquid passing in the pressure bar. Under the pressure bar there is the working jaw. It has “V” slot for clamping the specimen. A diaphanous organic glass protective cover mounted on the working table is used for observing and protecting when cutting. There are in-out water path and cooling liquid switch in the machine. The consumption of the cooling liquid could be adjusted or closed according to the cutting requirement. Cooling water tank is used for storing the cooling liquid for recycling use. For cutting the specimen of the rock or ceramic materials, the diamond cutting disc should be used.
