CNC machining (Computer Numerical Control) is a modern machining technology that uses computer programs to automatically control machine tools for high-precision and high-efficiency manufacturing. Its core principle is to convert design drawings into CNC codes, which drive machine tools (such as milling machines, lathes, and machining centers) to perform cutting, drilling, milling and other operations on metals, plastics and other materials according to preset paths to achieve precise transformation from blanks to finished products.

Zhonghuan is deeply aware of the importance of machining processes to the upgrading of foundry enterprises, so in the early days of its foundry business in 1995, it built a CNC machining workshop simultaneously. We do not regard processing as an isolated link, but position it as a core process to ensure the quality of aluminum castings. CNC processing is the core link of aluminum casting finishing and is also a key support for Zhonghuan to create a one-stop service.

CNC machining in Central

Relying on diversified aluminum casting production capabilities, combined with processing and other finishing services, Zhonghuan has built a one-stop supply system based on the principle of "quality first, integrity is gold" - allowing customers to obtain finished products from a single source in a shorter cycle and at a lower cost.

More than 100 sets of processing equipment and 120 sets of other professional equipment

--Comprehensive CNC machining capabilities
Zhonghuan can provide complete CNC machining services, including: CNC milling and turning Drilling, tapping and reaming Boring and grinding Precision testing and quality verification All processing fixtures are independently designed and manufactured by our in-house tooling shop to ensure repeatable positioning accuracy and processing consistency. By scientifically planning the entire production process from casting to final machining, we achieve seamless connection between each process and ensure stable and reliable product quality.
--Strict quality assurance system
We will conduct random inspections or full inspections according to customer needs to ensure full compliance with technical requirements. Our metrology laboratory is fully equipped with testing equipment, including: Vernier caliper Outside and inside diameter micrometers Go/No-Go Gauge Depth Gauge and Height Gauge Surface roughness meter High-precision coordinate measuring machine (CMM) with measurement accuracy of ±0.001 mm In order to eliminate the impact of temperature fluctuations on measurement results, the CMM equipment is placed in a constant temperature room to ensure the accuracy and repeatability of inspection data.

--Commitment to excellence

All CNC machine tools and inspection instruments undergo regular maintenance according to strict plans to maintain high precision and efficiency. Our team of programming engineers and operating technicians are well-trained, always adhering to the focus and ingenuity of precision manufacturing, and are committed to continuously improving product quality and customer satisfaction.

The whole process of processing

◉ Customize the plan according to the product drawings provided by the customer

The drawings include three-dimensional drawings, three-dimensional views and aluminum alloy material specifications of the product; if it is a two-dimensional drawing, we will have professional engineers draw three-dimensional drawings and three-dimensional views to confirm with the customer first to ensure that the subsequent processes proceed normally.

◉ Team engineers evaluate the project and develop detailed product process plans based on the drawings

Determine which casting process to use, whether a customized mold is required, and determine the processing steps and processes.

◉ Prepare raw materials

We have a stable supplier of aluminum alloy raw materials, and we will constantly update raw materials to ensure high quality; of course, we are equipped with professional testing equipment for spectral analysis and quality testing to ensure that the material composition meets standards.

◉ Produce samples for inspection to ensure the quality of subsequent mass production.

Customers can inspect the sample in person or we can send a sample test report to ensure that the product parts pass the test. The report includes the product's appearance, dimensional inspection table and actual performance.

◉ Team engineers evaluate the project and develop detailed product process plans based on the drawings

◉ Product post-processing

The parts undergo ultrasonic cleaning, air tightness testing, sand blasting, sawing, heat treatment, etc., depending on the steps required for the specific parts.

◉ Product quality inspection

Finished parts will be randomly inspected or fully inspected to ensure that aluminum castings meet standards.

◉ Packaging and transportation

We have a dedicated packaging workshop to safely package products to ensure they are not damaged during transportation.

What products can we produce?

1. Products with complex shapes
2. High-precision products: accuracy up to 0.01mm,
3. Products with higher surface requirements can reach the standard of Ra0.6
