Overview of LDQ-350 Manual Metallographic Cutting Machine:
The LDQ-350 manual metallographic cutting machine is a vertical large-scale cutting machine designed and produced by our company based on the health and safety standards of the European Community, introducing advanced cutting machine production technology from abroad. The machine consists of a cutting system, lighting system, cooling system, and cleaning system. The scientific manual cutting rod design makes cutting large workpieces very easy and effortless. This machine is particularly suitable for use in colleges and universities, the automotive manufacturing industry, steel enterprises, and material research institutions.

　　Functional purpose:
The LDQ-350 manual cutting machine is a vertical large-scale metallographic cutting machine designed and manufactured based on the principles of safety and environmental protection. It is suitable for cutting samples of various metal and non-metal materials, in order to observe the metallographic and lithological structure of the materials. This machine has stable operation, low noise, easy operation, and safe use, making it one of the essential equipment for making solid material samples in the laboratory.

　　Structure and safety:
The LDQ-350 manual cutting machine consists of a cutting system, cooling system, lighting system, cleaning system, etc. The upper part of the equipment is completely covered by an openable protective cover, and in front of the protective cover is a large observation window, which, combined with a high brightness lighting system, allows the operator to grasp the cutting process at any time. The scientifically designed manual cutting rod on the right side makes cutting large workpieces very easy and effortless. A cast iron worktable with grooves, when paired with pliers, can handle cutting various shaped workpieces. The super strong cooling system ensures that the workpiece will not be burned during cutting. The cooling water tank is placed inside the equipment base, and there is a filter in the water tank for easy collection of residue and debris. The door type safety switch and explosion-proof cover ensure the safety of operators.

　　Maintenance and upkeep of metallographic specimen cutting machine
1. After the operation is completed, rinse the surface of the workshop and workbench with tap water and dry them.
2. Regularly clean the oil stains on the drag board, guide rail, and guide rail drive screw, and add lubricating oil in a timely manner.
3. After all work is completed, move the blade forward by about 10 centimeters to reset the stroke switch rocker arm.
4. If the cutting machine is not used for a certain period of time after use, a layer of lithium based butter should be applied to the moving parts of the blades and fixtures, as well as some rust prone areas inside the machine.
