The main performance and characteristics of machine tools:
1.The bed body is a base made of high-strength cast iron (HT250), which is the load-bearing component of the machine tool. The C-shaped structure, T-shaped bed body (slow wire body structure), and casting body are all cast using resin sand casting technology (slow wire castings use this technology), with two high-temperature annealing treatments. They also have a large self weight in the same type of machine tool, ensuring constant mechanical accuracy.

2.The X and Y axes adopt high-precision linear guides and high-precision ball screws, driven directly by AC servo motors to achieve semi closed loop control, and have pitch compensation function, ensuring the high precision and stability of the machine tool for long-term use.
Adopting a adjustable Z-axis for veneer processing, it effectively prevents molybdenum wire shaking, avoids cutting surface scratches, and greatly improves the accuracy and roughness of the processed surface. And the lifting mechanism adopts a linear guide rail, greatly reducing the verticality error, making it convenient to lift the Z-axis at any time during processing to remove waste.

3.The wire transport component adopts imported linear guide rails as the moving parts, and is controlled by a frequency converter. Whether at high or low speeds, it can ensure the smooth operation of the component, accurate speed regulation, greatly reducing the vibration of molybdenum wire during operation, and ensuring the processing quality of the processing end.

4. Equipped with a bi-directional independent automatic tightening mechanism for electrode wires, ensuring smooth operation and constant tension of the electrode wires, which can effectively reduce wire consumption and improve cutting performance.

5.The new generation of impedance free high-frequency power supply is an efficient and low consumption pulse power supply controlled by the intelligent high-frequency pulse power control system software of Baoma CNC reciprocating wire EDM cutting machine (obtained national copyright). It has real-time monitoring function and is matched with the intelligent servo tracking control system of Baoma EDM cutting machine (obtained national copyright) to adaptively adjust high-frequency energy, effectively improving processing efficiency and greatly reducing equipment power consumption - significantly energy-saving. Due to the impedance free design, its own heat production is extremely low.

6.The CNC system adopts an embedded control system, which seamlessly connects with various design software such as ATUOCAD, and is compatible with various formats of graphic files such as DWG and DXF.

7.Equipped with powerful network communication functions, achieving data transmission.

8.Equipped with a Baoma Electric Spark Wire Cutting Machine Intelligent Database Control System (with national copyright), users can choose according to different workpiece cutting needs, provide a fuzzy input system, and have a system that automatically matches suitable parameters, simplifying the requirements for operators, especially suitable for beginners. At the same time, the system also supports DIY to configure processing parameters independently to adapt to special processing requirements.


9.The multi-layer filtering water tank extends the service life of the working fluid, improves the cleanliness of the working fluid, enhances the slag removal performance, and ultimately promotes the improvement of the smoothness of the processed workpiece. Combined with the use of Baoma's latest cooling liquid - water-based working fluid, it is harmless to operators and the environment, and meets environmental protection requirements,
The automatic timed centralized oil supply system facilitates lubrication of the main parts of the machine tool (X, Y guide rails, screw rods), ensuring the service life of the machine tool and reducing the workload of manual maintenance.


10.AR tilt automatic correction function. If the reference edge of the workpiece is not parallel to the X or Y axis, the system can rotate the program to a certain angle through edge collision testing, making it parallel to the workpiece reference, thereby reducing the workload of the operator
