A high-precision hydraulic manifold block, has been adjusted by the original manufacturer for many times, the benchmark error of the hydraulic manifold block still cannot be eliminated. AAK took it over under the introduction of old customer, optimized the original processing technology, and added the finishing boring process before the vertical drilling sequence to re calibrate the positioning of the V-shaped block, so that the benchmark error of the hydraulic manifold block was controlled at 0. Tom sent the order of the hydraulic manifold blocks of more than 20000 dollars.
Tom is from Holland. They should be the top 3 of the hydraulic companies in Holland. Tom, introduced by his friend Mathias, sent us an inquiry for hydraulic manifold block. After communication, we knew that Tom learned from Mathias that AAK hydraulic technology has changed every year in recent years, and have supplied hydraulic manifold blocks to the world's top 500 companies, so he contacted me.
Tom told us the problems with the original hydraulic manifold block manufacturer. Turning Φ 215mm excircle and Φ 88mm inner hole, outer circle center as benchmark, turning Φ 205h8 uses a special fixture, which also uses the outer circle center as the reference for turning. There should be no datum misalignment error, but the hole position is out of tolerance. After 2 days of discussion, AAK hydraulic engineers basically determined that it was caused by the positioning error of V-shaped block in the machining center. Tom was surprised by our analysis and half believed it. I told him that AAK was willing to sample this hydraulic manifold block. If the parameters were not up to standard, the development cost would be refunded. After 30 days, AAK sent 5 hydraulic manifold block samples.
2 months later, Tom sent us the official order for hydraulic valve block of more than 20000 dollars. The reason why AAK can effectively solve the positioning benchmark error is that starting from the production process, it deliberately adds the finishing boring process before the vertical machining sequence drilling to re calibrate the positioning of the V-shaped block.
After optimization of AAK hydraulic manifold block: vertical machining center, turntable rotates to 90 ° fine boring φ 88H7 inner hole → drill φ 215mm on cylindrical end face φ 25mm hole allowance → boring φ 25mm hole → rotary table rotates to 0 ° for fine boring φ 110H7 hole → finish milling φ Upper end face of 53mm hole → drill φ On 205mm excircle end face φ 22mm hole allowance → boring φ 22mm hole → rotary table rotates to - 90 ° fine boring φ 88H7 inner hole → drill φ 215mm on cylindrical end face φ 25mm hole allowance → boring φ 25mm hole.
The optimized processing technology can reduce the influence of datum movement error to zero, and the positional and vertical accuracy can be better guaranteed.
