Kedma checked with several hydraulic manifold manufacturers but found no results. AAK solved his problem with 2 symmetrical milling cutters

China [CN]

Last week, Kedma from Israel left a message on the hydraulic manifold manufacturer AAK website:

1. We need to customize a hydraulic manifold block, for each 2 opposing faces of the 6 faces of the manifold block, its accuracy must be the same.

2. This hydraulic manifold block is intended for military equipment. If it does not meet the requirements, please do not provide a quotation.

I saw this message and did not reply directly. But instead, I asked Kedma, ‘You should have checked with many hydraulic manifold manufacturers, right? And most of these hydraulic manifold manufacturers gave no reply or said No.’ Kedma agreed with my guess and asked me how I found out. I told Kedma that most hydraulic manifold manufacturers in China are not confident, especially when it comes to military products, they are a bit scared. Moreover, Kedma has special requirements, and these hydraulic manifold manufacturers do not want to cause trouble, and some hydraulic manifold manufacturers do not have the ability to do so.

Kedma seems to be interested in AAK and asked me how much time and cost it would take to customize this hydraulic manifold block, and how can AAK ensure that the accuracy of the 2 opposing faces of the hydraulic manifold block must be consistent? I said, before providing a quotation and development, let's first watch a video of how AAK processes hydraulic manifold blocks.

From the video, it can be seen that the key points are the 3 steps:

1. The processed hydraulic manifold block should be properly positioned to ensure centering.

2. The processed hydraulic manifold block should be securely fixed to ensure no displacement

3. The 2 opposing faces of the hydraulic manifold block are processed and milled simultaneously.

The double-sided milling machine is a perfect match for Kedma's special requirements for hydraulic manifold blocks. It is driven by the spindle and simultaneously drives 2 symmetrical milling cutters. At the same speed and milling depth, the surface roughness of the 2 opposing faces of the hydraulic manifold block is also synchronously controlled. The 2 symmetrical milling cutters are capable of cutting 360 degrees without dead angles in front and back, up and down, left and right. The processed hydraulic manifold blocks do not need to be flipped, avoiding secondary positioning errors. Most hydraulic manifold manufacturers process the hydraulic manifold blocks by one face to another, which not only has low efficiency and unstable accuracy, but also cannot achieve the same accuracy of hydraulic manifold blocks on 2 opposite sides.

AAK hydraulic manifold blocks, processed on 2 opposite sides simultaneously, with no errors, you can also try it out.
