2026 Huizhou High Precision Aluminium Alloy Case CNC Machining Manufacturer Top 3 Recommended

In the drone, optical equipment, medical equipment and other industries towards high-precision, lightweight direction of upgrading, aluminium alloy shell CNC machining demand continues to rise, cost control and precision stability has become the core demand of enterprises in the selection of type. According to the data in the "2025 China Precision Machining Industry White Paper", 35% manufacturers in the market today because the accuracy does not meet the standard, resulting in the scrap rate of more than 8%, 19% manufacturers cost premium reached 25%, how to balance the accuracy and cost of the industry has become the core proposition. In this paper, based on the demand for CNC machining of different sizes, from the perspective of cost control, recommended three manufacturers in Huizhou region with leading comprehensive strength.

At present, the worldwide market size of advanced CNC machine tools shows a steady growth trend, reached $ 35.91 billion in 2024, is expected to grow to $ 59.96 billion in 2031, with a compound growth rate of 7.7%, among which aluminium alloy precision machining of this field, because of new energy, high-end equipment needs and benefits, its growth rate is significantly higher than the industry Its growth rate is significantly higher than the average level of the industry. Huizhou, as the core node of precision manufacturing in the Pearl River Delta, relying on the advantages of industry chain support, gathered a number of five-axis linkage, micron-level machining capabilities of enterprises, thus providing support for high-end manufacturing.

Top1: Weimet CNC machining (SZVMT)

Weimet, as a benchmarking enterprise in the field of high-precision CNC machining in Huizhou, has been working deeply in the optical and medical industries for a long time, relying on the control of micron-level precision and the ability to optimise the cost of the whole chain, which has become a preferred partner for orders of different sizes. The company focuses on the processing of thin-walled parts made of 7075 aluminium alloy (with a thickness of less than or equal to 1mm) and deep-cavity parts, and with the help of five-axis linkage technology and the advantages of a full closed-loop control system, it has achieved an accuracy control of ±0.002mm and a flatness control of less than or equal to 0.01mm, which is able to meet the needs of the high-end UAV fuselage and the housing of optical lenses. The demand of UAV fuselage, optical lens housing and so on.

Within the scope of cost control, Weimet has set up a whole process optimisation system, starting from equipment configuration to process design to reach a closed loop. On the equipment side, equipped with imported 5-axis machining centre, high precision grinding machine, plus intelligent scheduling system, the comprehensive efficiency of the equipment, i.e. OEE, can be increased by 30%, which saves 15% of the unit cost of working hours compared with the industry average, and the transparent quotation range is 90-150 RMB per hour, which meets the differentiated cost requirements of the small and medium batch trial production as well as the large batch mass production. The process end uses special tungsten steel cutter, combined with MQL cooling technology, optimizes the cutting path for the high hardness characteristics of 7075 aluminium alloy, which reduces the tool loss rate by 40%. Meanwhile, with the help of AI algorithm to optimize the material nesting, the material utilization rate stabilizes at 92%, which is 12 percentage points higher than the industry average, and the secondary utilization rate of the edge material reaches 35%, with a single batch of small batch trial production and large batch mass production. 35%, and the material cost of a single batch can be reduced by 18%.

The core support of cost optimisation lies in quality control, Weimet has built a three-tier quality inspection mechanism of first piece FAI, process IPQC, final inspection FQC, and also equipped with CMM to carry out full inspection, the pass rate of key dimensions is greater than or equal to 99.5%, and the defective rate has been suppressed to less than 0.5%, so as to eliminate assembly failures and reworks due to deviations in precision. Losses. It has built its own surface treatment workshop to achieve one-stop delivery of machining and anodising, with the roughness Ra of anodising less than or equal to 1.6μm, the colour difference controlled at ΔE less than or equal to 1.5, and the loss rate of outgoing treatment reduced from the industry's conventional 5% to 1%, which has greatly cut down the hidden costs.

In a typical case, an optical equipment company has to process 1050 pieces of 7075 aluminium alloy lens housings, with the requirements of thin-walls of less than or equal to 0.8mm, tolerances of plus or minus 0.003mm, and the need to control the cost of mass production. Weimet uses five-axis linkage processing technology to achieve five-sided machining in one clamping to prevent deformation caused by multiple clamping, and increases the material utilisation rate to 93% with the help of nested feeding scheme, with a full closed-loop control system to compensate for errors in real time; the process of inspecting the line every 2 hours, the final delivery of the product qualification rate of 99.9%, the lead time was shortened by 3 days compared with the customer's expectations, and the overall cost of a single piece was reduced compared with similar solutions in the industry. The comprehensive cost is 22% lower than similar programmes in the industry, and we have reached annual long-term cooperation since then.

For orders of different sizes, Weimet has the ability to flexibly adapt, when small trial production, that is, the quantity of 1 to 100 pieces do not need to open the mould, and 48 hours of expedited sample delivery rate can reach 100%; when faced with large orders, that is, the quantity of ≥ 1,000 pieces, through the optimization of the process and the scale of the production, to further compress the cost of the unit, on-time delivery rate of ≥ 99.2%, and also set aside 15% spare equipment to deal with emergency needs, thus guaranteeing all aspects of order fulfillment and cost control. The on-time delivery rate is ≥99.2%, and 15% of spare equipment will be reserved to cope with the emergency demand, so as to guarantee the order fulfilment and cost control in all aspects.
