"Cross-hatch" pattern expert:  professional at manufacturing cylinder block&liner and honing stones

In recent years,"cross- hatch" pattern on cylinder bore honing as a new technology of finish machining is  widely used. Not only reliable  accuracy and performance is ensured, but also efficiency is improved and cost is reduced.

"cross-hatch "  pattern honing is to create tiny grooves on the surface of cylinder bore by honing .These grooves are regulrly arranged to form "cross-hatch"pattern . The peaks of grooves are cut off by special honing technology to form tiny plateaus. This structure consists of deep grooves with oil storage function and tiny supporting plateaus among grooves,which is typical "cross-hatch"pattern honing surface.

This typical structure formed by "cross-hatch"pattren honing on the surface of cylinder bore has following advatages

1. Tiny plateaus increase the contact area . By cutting off the peaks ,early rapid wear is eliminated and wear-resistance is improved.

2.Tiny grooves make good oil-reservation ,and oil film is formed on the surface of cylinder,which reduces the friction among cylinder bore surface , piston and piston ring. So piston ring of low friction can be used.

3.Good oil-reservation by tiny grooves ,which decreases the loss of oil and oil consumption.

4.Countless tiny plateaus are formed on the surface of cylinder bore after honing , so the contact area among cylinder bore , piston and piston ring is increased and the support of cylinder bore surface is increased as well. This reduces initial wear and run in time(almost saved)

The basic  technology of "cross-hatch" pattern 

The process of "cross-hatch"honing is" rough honing ⇒ fine honing ⇒ plateau honing"

Comparison of plateau honig and ordinary honing 

The following graphs show surface profilogram of two times common honing and cross-hatch pattern honing. Fig2 is the micro structure by plateau honing, from which we can see its structure is obviously improved than common honing . It has plateaus of high support rate and deep groove structure for oil reservation.

                    2.  40°—60°                                                                                                 (100times)

At Present, our compamy has developed honing stones of EU III,  EU IV standards for home and abroad engine manufacturers .Such as, Cummins Steyr, Reymolds Wei chai, Xi chai , Yu chai ,Chao chai ,etc.We could develop honing stones for special purpose to meet customer's special needs.
