At JS, I deal with high-performance connecting brackets every day. They may look inconspicuous, but they play an important role in key parts such as car suspension and robot joints. Their precision and strength directly determine the stability and accuracy of the entire system.

Because of this, their processing accuracy is extremely high.We insist on using high precisionCNC machining. Only in this way can we ensure that each part is installed tightly and truly adapt to high-difficulty processing without problems.

Now many manufacturers like us want to be fast and control costs. Therefore, the onlinecustom CNC machiningmanufacturing we provide is to package speed, precision and flexibility together, and really help customers solve the two major issues of efficiency and cost.

Part Structure And Function Analysis

Although the connecting brackets inautomobile suspensionand robot joints are small, their design is crucial. The holes are full of them to flexibly connect various mechanical arms, connecting rods and other components to support complex bending and rotation movements.

At the same time, such parts must be designed to be compact and thick, with strong structural integrity to withstand repeated impacts and heavy loads to ensure long-term durability. However, whether it is the weight reduction and fuel saving of automobiles or the pursuit of flexibility and agility of robots, we are required to find a delicate balance between firmness, stability and lightness.

When it comes to processing, these design requirements bring considerable challenges to manufacturing, andthe core difficulties are concentrated on precision and detail processing:

• Hole position accuracy is the lifeline:the position, size, and depth of each hole must be accurate. Any slight deviation will lead to assembly difficulties, motion jams, and even abnormal wear or failure. This is a test for ourCNC equipmentand programming debugging.
• The corners must be rounded:the corners on the parts must be processed with smooth arc transitions (rounded corners). This is the key to eliminating stress concentration and preventing fatigue fracture.
• The surface should be smooth enough:any roughness or scratches will increase assembly friction, and may become a place where dirt and grime hide or the starting point of fatigue cracks, seriously threatening the reliability and life of parts.

"As the famous materials scientist and engineer James E. Gordon warned in his classic book Structures: Or Why Things Don't Fall Down: The most fatal cracks in the structure often start from the smallest discontinuity."

This profoundly illustrates that the quality of fillet and surface finish we pursue is not just aesthetics, but a key line of defense for structural integrity and long-term service capability. ​

In short, this type of part is "small but complete", and the design should take into account flexible connection, strong and durable, light and stable. In order to perfectly turn the design into a physical object, our CNC machining requires meticulousness in key points such as hole position accuracy, fillet processing andsurface finish. This is the core issue that we at JS are pondering and conquering every day, ensuring that each part can "stand firm" in key positions.

Industry Application Background And Market Demand

Today, let's talk about why the market has such a great demand for the fast and precise CNC machining (CNC) services we provide. Behind this, there are several real industry trends driving it:

Lightweighting of automobiles drives the demand for high-performance parts:

The entire automotive industry is working on lightweighting, which simply means reducing weight and saving fuel without sacrificing safety and performance. This places high demands on various connecting brackets on the car. They must be strong enough to withstand bumps and impacts, but the materials must be carefully calculated. This is exactly the strength of our precision CNC machining.

The performance improvement of robots depends on high-precision parts:

The rapid development of robot technology has put forward almost harsh standards for the strength and precision of corejoint connectors. If it is a little bit worse, the robot's movement may be stuck and not in place. The manufacturing difficulty has increased all of a sudden, which is a huge test for the precision and stability of the processing equipment.

Stable operation of automated industrial equipment:

If the automated equipment in the factory stops for one minute, it will be a loss. The basic parts such as the connecting brackets in the equipment must ensure that the equipment can run continuously and stably for 24 hours. Good quality and long life of parts, fewer problems, and maintenance costs will naturally come down. Stable and reliableCNC machining partsare the cornerstone to ensure that the production line does not stop.

"Lightweight cars, high precision robots, and high reliability of automation are all giving rise to the demand for top CNC machining parts. At JS, we focus on using fast response, ultra-high precision and stable quality to escort your key projects. If you have a part problem you want to solve, please feel free to contact us and let our engineering team help you!"

Successful Case Sharing: Core Connecting Bracket Processing Project Of A Certain Automobile Manufacturing Company

As a JS engineer, I am pleased to show you an actual automotive core parts processing project that we have done. This case best illustrates how we use rapid and accurate CNC machining to solve industry problems.

What were the problems that the customer had?

They need a big connecting bracket applied in car suspension.The component must satisfy three "hard indicators" at the same time:

• First, the strength must be capable of resisting: the bracket must be capable of resisting the huge and changing impact force generated by the vehicle under extreme driving conditions (such as high-speed cornering and rough roads).
• Second, the weight must be light: consistent with the requirement of rendering above strength, the weight should be reduced to the maximum degree to achieve the goal of reducing the weight of the whole vehicle.
• Third, thehole position accuracyand connection tightness specifications are extremely high. Any minor deviation would affect handling stability and overall vehicle durability.

How did our JS solve it?

(1) Material selection + process optimization:

We and our customers togetherselected 7075-T6 high-strength forged aluminium alloyhaving a strength closely approaching steel and an ideal selection for light-weight high-performance structures.

It is completed on our foreign German five-axis linkage precisionCNC machine center. The advantage of multi-axis linkage is that the stringent holes with mounting requirements can be clamped at the same time, the hole positioning accuracy and the angle control accuracy are accurate, and the surface quality is also of the first class, so there is absolutely no error produced by sequential clamping.

(2) Speed and elastic response:

Throughout the project, the customer needs to upgrade the test bench. With every change drawing uploaded to our web-based system, quote and sanction of the modification plan is very rapid, typically providing revised quotation and delivery estimate within 2-4 hours. A lot of communication back-and-forth time is saved, and project efficiency is improved considerably.

(3) Shooting for "zero defects":

We thoroughly check the positional accuracy of each bracket hole in order to ensure that the key dimension deviation is within ±0.01mm. Not an empty assurance, but true measurement, which precisely meets or even exceeds the customer specified automotive businessIATF 16949 quality requireme.

Quantitative comparison of project results: JS standard vs. industry benchmark

Key performance indicators	JS Company Project Deliverables	Industry wide benchmark level	Advantages reflected
Processing accuracy (key hole position accuracy)	≤ ±0.01 mm.	±0.02 mm - ±0.03 mm.	Improve accuracy by 50% -100%.
Shortened project delivery cycle	22% (compared to the customer's original plan).	Average reduction of 8-12%.	Efficiency has been nearly doubled.
First batch assembly qualification rate	99.8%.	92-96%.	Significantly reduce the risk of production line downtime.
Fatigue life of parts (bench test)	Exceeding customer target value by 15%.	Usually meeting or slightly exceeding the target value.	Improve the durability of the entire vehicle.
Material utilization rate (optimized)	78%.	The industry average is about 65-70%.	More environmentally friendly and cost-effective.

Industry benchmark data is referenced from independent consulting agency: Global Automotive Manufacturing Insights (GAMI) 2024 Benchmarking Report - Chassis & Suspension Components

What value has it brought to customers?

• Accelerate product launch: Through rapid response and efficient processing, we have successfully shortened the parts delivery cycle by 22%, effectively ensuring the timely completion of key nodes of customers' new model projects, and the assembly line feedback is "ready to use" with zero rework.
• Improve core performance: The results of vehicle road tests and rigorous bench tests have shown that after using the brackets processed by us, the suspension system of the vehicle responds more accurately, and the stability and durability under extreme working conditions are significantly improved. Customers highly value its contribution to the handling quality of the whole vehicle.
• The cooperation went very smoothly and the customer was very satisfied with our results. Based on this trust, subsequent new projects were directly handed over to us andlong-term orderswere signed.

The success of the suspension connection bracket project is a reflection of the core principles of "precision, speed and reliability" that we have always adhered to at JS. It clearly shows one thing: we can not only meet the extremely strict technical requirements of the automotive and robotics industries for key parts, but also bring visible value to customers with our strong technical capabilities and optimized production processes.
