The quality of your hydraulic system plays a vital role in the performance and reliability of your products. A critical factor to this performance is the fit between the spool and the valve bore. Achieving optimal clearance between these two components results in improved performance, lower propensity for leaking, better hysteresis, fewer repairs and increased reliability.
Engis Single-Pass Bore Finishing and Multi-Stroke Honing technologies deliver superior-fitting bores. We have over 40 years of focused experience in the development of Single-Pass technology, specifically for hydraulic applications achieving:
Our four Process Development labs work with you to achieve your production objectives in terms of fit, finishes and overall manufacturing cost and part quality. No other company has in-depth expertise in diamond and CBN characteristics, or the capacity to engineer complete superabrasive finishing systems as Engis. Let our drive and competitive spirit help you accomplish your goals. Get additional information on:

Single-Pass Reduces the Need for Match Grinding
To avoid potential leaking of the finished assembly and maximize performance of the hydraulic component, close mating of the spool and sleeve may require clearances of 1.27µm - 0.508µm. This fit is often achieved by either "Match Grinding" the spool to the finished sleeve or by skilled craftsmen who hand lap the sleeve to suit the mating spool. Engis Single-Pass Bore Finishing ensures proper fit between the spool and valve body WITHOUT Match Grinding. Result = Save Time, Save Money.....
