From the customer complaint about the first prototype machining set last year to the signing of a new order for 5 sets of machined parts in July this year, how did we provide our customers with satisfactory precision machining solution? Please let me explain in detail.<\/p>\n

 <\/p>\n

Receiving New Machining RFQ<\/h2>\n

June 25, 2026. We received an inquiry from a Swiss customer regarding some precision parts we had made last year, including one aluminum bent tube product along with three other complex precision parts. If you have read our previous articles<\/a>, you may recall that this bent tube had previously led to a customer complaint, and we even compensated the customer for the cost of the goods.<\/p>\n

Now the customer has come back to us again, which shows a great deal of trust in us. No matter what, we must do our utmost to provide the customer with a high-quality solution.<\/p>\n

Searching for a Smarter Precision Machining Solution<\/h2>\n

<\/h3>\n

The Bent Tube<\/h3>\n

The first challenge was the bent tube.<\/p>\n

Quantity: just 1 piece. Dimensions: completely non-standard. If we wanted to open a new mold, the cost would be sky-high\u2014and worse, almost no factory would even take the job for a single piece.<\/p>\n

I called around. A lot of tube bending shops. Most of them went silent the moment I said “one piece.”<\/p>\n

But I didn’t give up. Through those conversations, I learned something useful: some shops had existing molds with specifications close to what we needed\u2014though the bending radius and tube diameter weren’t an exact match.<\/p>\n

So I sat down, drew two alternative sketches based on what I found, and sent them to the customer. I asked:\u00a0Which option works better for your assembly?<\/em>\u00a0I also suggested increasing the order to 5 pieces to make the cost workable, and gave them a full breakdown of bending, machining, and surface treatment fees.<\/p>\n

\"Aluminum<\/p>\n

The two existing sizes of the bending pipe molds<\/p>\n

 <\/p>\n

The good news? The price per piece went up only 17% compared to last year’s single-piece run (welding+machining)\u2014far cheaper than custom tooling.<\/p>\n

The customer replied the very same day. They chose to keep the tube size as per their drawing, and allowed us to use the existing mold’s bending radius.<\/p>\n

Just like that, the first hurdle was cleared.<\/p>\n

 <\/p>\n

The Three Complex Parts<\/h3>\n

Now came the other three parts. These were tricky.<\/p>\n

Last time, we machined them with horizontal CNC milling and multiple clampings. The results weren’t great\u2014one part even went out of tolerance, and we had to send a replacement. The customer accepted it, but I knew we could do better.<\/p>\n

This time, I sat down with our engineering and production teams. We reviewed every angle\u2014literally. And we made a decision:\u00a0let’s use Servizi di lavorazione di precisione CNC a 5 assi<\/strong><\/a>\u00a0for these three parts.<\/p>\n

Why?<\/p>\n
