JSEDM specializes in developing its own control systems to ensure stable performance and user-friendly operation.
From initial design and component selection to pre-production trials and continuous optimization based on customer feedback, our control systems are designed to deliver high efficiency, reliability, and low maintenance costs.

To ensure consistent machine quality and long-term performance, every JSEDM machine undergoes a series of strict testing and validation processes throughout each stage of production.
From key component inspection to full machine testing before shipment, we maintain rigorous quality control to guarantee stable machining performance and operational reliability.

Quality Control Process :

Every JSEDM machine undergoes strict quality control throughout the entire manufacturing process. From incoming inspection to final machine testing, we ensure consistent quality, stable performance, and reliable operation for every machine delivered to our customers.

1. Incoming Inspection

All key components are strictly inspected upon arrival to ensure material quality and specifications meet required standards, forming a solid foundation for machine reliability.

2. Mechanical Assembly

Precision assembly using high-quality components ensures machine rigidity, stability, and long-term operational reliability.

3. Electrical Assembly

Our engineers perform precise wiring and system integration to ensure stable signals and accurate control system performance.

4. Machine Testing

Each machine undergoes full operation and actual machining tests to verify accuracy, stability, and machining performance.

5. Final Inspection

Before shipment, every machine is subject to final quality checks and functional verification to ensure it meets our delivery standards and customer requirements.

About JSEDM

Providing Customize Solution

To adapt to the changing environment of current global market and to meet customers' demands for product integration and standardization. In 2015, JSEDM introduced Abrasive Fluid Machine to complete customer's processing and production needs. In addition to provide polishing services, JSEDM offers customer process optimization advice and solutions to overcome the challenge of the low-cost competition brought about by globalization and at the same time reduce the energy consumption of the machine.

Machine Features and Control

JSEDM has strict requirements for the production environment and the quality of finished products. The factory is equipped with air conditioners to ensure a stable environment temperature. To ensure that every customer's machine is of the highest quality, each product must pass multiple stages of testing, and with the final confirmation by JSEDM chairman before shipment.

The design of the machine not only simplifies the assembly process but also reduces the possibility of mis-assembly in the production process and enhances stability to achieve high-precision cutting. The simple configuration aims to make the operation more convenient and intuitive for the user.

Research and Development

JSEDM research and development team focuses on developing machine that is easy for users to operate while maintaining high precision and stability. Each axis of the machine is tested and verified based on different production environment and different selection of material, ensuring that the machine can meet customer product precision requirements.

The R&D team also cares about environmental impact caused by production waste. By simplifying the manufacturing process and implementing waste recycling and filtration, they aim to reduce harm to the planet and accomplish sustainable development.
