Welcome to the world of Zhengrong Precision Machining! Here, you will encounter a machinery processing factory with a glorious history spanning nearly 20 years. We are one of the oldest precision machinery processing factories in China, having witnessed the changes and development of the industry.
CNC Machining
Our company is equipped with more than 15 high-speed, high-precision CNC machining equipment with a processing accuracy of up to ±0.005 millimeters. This equipment demonstrates robust processing capabilities for a variety of materials, including metals, plastics, and composites. Leveraging their expertise and extensive experience, our senior technicians fully utilize the advantages of these machines to manufacture components with complex shapes and strict tolerance requirements. Our technical superiority is particularly evident in the field of precision instrument manufacturing.
CNC machining technology plays a pivotal role in the production of core components such as optical instrument barrels, precision mechanical parts, and sensor housings. These components have extremely high requirements for dimensional accuracy, form accuracy, and surface quality. With the skilled operation of our senior technicians, our company's CNC machining equipment not only meets these stringent standards but also ensures the quality and precision of each product due to its excellent processing capabilities and efficient production efficiency. This perfectly aligns with the processing needs of precision instrument components.
Turning
Our company is equipped with multiple high-precision CNC lathes with a rotational speed of up to 6000 revolutions per minute and a processing accuracy of ±0.002 millimeters. We can also refine the roughness to a mirror-like finish of Ra0.4 according to customer requirements. Tool steel subjected to heat treatment demonstrates even better surface finish under our lathe turning process.
Turning technology is particularly suitable for mass producing rotationally symmetric precision components such as shafts, bearings, and gears. These components play a vital role in precision instruments, such as shafts and bearings in transmission systems and rotating parts in precision measurement instruments. Our CNC lathes, with their high-speed and efficient processing capabilities, can quickly produce these critical components while strictly adhering to tolerance requirements and surface quality standards.
Our technicians, with their extensive experience and proficient skills, can fully utilize the high precision and high efficiency of the lathes to ensure that each product meets customer expectations and requirements. Whether in terms of processing accuracy, roughness, production efficiency, or quality stability, our CNC lathes and technical team demonstrate unparalleled advantages.
Surface Grinding
We are equipped with multiple advanced surface grinding machines capable of ensuring a high standard of dimensional accuracy of ±0.002 millimeters for parts, while achieving a mirror-like finish with a roughness of Ra0.4 according to customer requirements. Our technical team has accumulated rich experience in centerless grinding, surface grinding, internal and external cylindrical grinding, and excels in processing high-precision complex components including arcs, steps, and grooves.
For different material types, we flexibly select various types of grinding wheels such as brown alumina wheels, diamond wheels, and resin wheels, and precisely match the most suitable processing scheme based on the difference in grit size of the wheel bonding particles. In the field of precision instrument manufacturing, our grinding technology is widely used for processing complex-shaped components with extremely high requirements for surface roughness, form accuracy, and dimensional accuracy, such as precision mechanical components for optical instruments and high-precision parts for measurement instruments.
With our exceptional grinding process, we can ensure that the flatness, perpendicularity, parallelism, and other positional tolerances of these critical components meet extremely high standards, satisfying the stringent accuracy requirements for parts in precision instruments, and effectively supporting the manufacturing and upgrading of precision instruments.
Wire Electrical Discharge Machining (WEDM)
We are equipped with multiple high-precision Wire Electrical Discharge Machining (WEDM) devices. Our professional technicians, through precise wire cutting processes, can ensure a high standard of dimensional accuracy of ±0.01 millimeters for parts while effectively preventing deformation during the machining process. During the WEDM process, we exercise extreme precision in controlling the loss of cutting edges, profiles, internal holes, and eroded surfaces, thereby achieving high-precision maintenance of thickness dimensions.
It is particularly noteworthy that our WEDM technology demonstrates exceptional performance in processing high-strength, high-hardness materials such as hardened steel, as well as complex geometries that are difficult to tackle with traditional machining methods. In the field of precision instrument manufacturing, this technology is often used to machine components with micro-holes, precision slits, and complex curved surfaces. These components have extremely high requirements for dimensional accuracy, geometric shape accuracy, and surface quality.
We use fine molybdenum wire as the electrode. Leveraging the high precision and flexibility of WEDM technology, we can achieve precise cutting of these high-precision, high-complexity components. This technology not only meets the stringent accuracy requirements for parts in precision instrument manufacturing but also demonstrates our professional strength and technological advantages in the field of machinery manufacturing.
CNC machining, turning, milling, grinding, and WEDM each have their advantages in the processing of precision instrument components. Our company will reasonably select the appropriate machining method according to the requirements of the machining process to ensure the production of high-quality, high-precision precision instrument components for you.
