Hydraulic Manifold Block Optimized Processing Technology - China

For the Hydraulic Manifold Blocks that more than 30 Manufacturers were not able to produce, AAK solved it in 3 steps The original manufacturer of the hydraulic manifold block made samples for 3 times, pushed the delivery for 3 times, but the samples were still not approved.

There was always 0.5~1.0mm burrs in the deep hole of the hydraulic manifold block.

After AAK took over, in terms of process, it abandoned the conventional route, optimized 3 points, and got the samples approved at one time.

Tom from Holland, their customer wanted to develop a hydraulic manifold block.

The maximum side length of the hydraulic manifold block is 800mm, including multiple 4 × M8 threaded holes and Φ 14, Φ 17 deep holes, and the accuracy is more than 10% higher than the conventional one.

Tom knew the difficulty of this hydraulic manifold block and the importance of this customer, so he selected 2 most recognized hydraulic manifold blocks manufacturers to make samples at the same time.

It took 8 weeks to sample 3 times, and there were still 0.5~1.0mm burrs in the deep holes of the hydraulic manifold blocks.

The customer was not satisfied.

If the next sample of the hydraulic manifold block still can not be approved, the order had to be cancelled.

Within 2 days, Tom contacted more than 30 hydraulic manifold block manufacturers, and those old suppliers suggested him giving up, which made Tom very anxious.

Tom found AAK website on B2B and noticed AAK has tricks on the processing and deburring of hydraulic manifold blocks.

With the attitude of trying, he contacted us.

When receiving the drawing of hydraulic manifold block sent by Tom, AAK technical team was also a little surprised.

The hydraulic manifold block is large size but with long and thin holes, and most of the holes are Φ 14, Φ 17 - The depth is more than 400mm, most of which are deep holes with a length diameter ratio greater than 28 - This is a challenge for machining, especially for deep hole machining.

The tool is long, chip removal is difficult, chip extrusion is easy, and the drill bit is easy to break, with many potential burrs.

2 days later, AAK technical team had a commencement plan.

I replied to Tom by email that AAK was willing to develop this hydraulic manifold block and is 90% confident to be successful.

After 30 days, we sent 5 hydraulic manifold blocks.

2 weeks later, Tom emailed us that the customer had approved AAK hydraulic manifold blocks, which not only met the accuracy standard, but also completely removed the burrs.

For the deep hole processing of this hydraulic manifold block, the other hydraulic manifold block manufacturers can not meet the precision and remove burrs completely, maybe they still use traditional technology.

AAK has always adhered to process innovation and technology optimization.

Aiming at the characteristics of this hydraulic manifold block, AAK has made adjustment and optimization from 3 aspects: 1 - Most hydraulic manifold block manufacturers use machine tools and gun drills to process deep holes.

The deviation of this hydraulic manifold block hole reaches 1/800 - AAK selects a machining center and adopts the two end butt joint processing technology.

First, use an alloy milling cutter to process a certain depth of the guide hole, and then use a short to long fried dough twist drill to process the deep hole, and strictly control the deviation error range of the hole.
