Hydraulic Honing Machine BHCN-140 - Cylinders Ø1.6-5.5IN

The cylinder honing machine is used for the final finishing of engine cylinders after machining. The honing process creates small crosshatch grooves on the cylinder wall, ensuring oil retention and perfect piston ring seating. The BHCN-140 handles cylinders from 1.57 to 5.51 inches (Ø40 to Ø140mm), covering car, motorcycle and light commercial vehicle engines, being essential for complete engine rebuilding.

The BHCN-140 hydraulic honing machine works with cylinders from 1.57 inches to 5.51 inches (Ø40mm to Ø140mm) in diameter. This range covers most automotive engines, from small motorcycles to passenger cars and some light utility vehicles. Being hydraulic, it offers uniform movement and constant pressure during honing, ensuring precise finishing. It's an imported machine with technical specifications that may change according to manufacturer evolution.

With the capacity from 1.57 to 5.51 inches (Ø40 to Ø140mm), you can hone cylinders from medium and large motorcycles, domestic and imported passenger cars, light pickups and some utility vehicles. 4, 6 and 8 cylinder engines fit this range. It doesn't work for small motorcycles (below 1.57 inches/40mm) or heavy diesel engines (above 5.51 inches/140mm). It's ideal for most jobs that arrive at neighborhood or passenger engine specialized machine shops.

The hydraulic honing machine like the BHCN-140 offers automatic movement and constant pressure controlled by the hydraulic system, resulting in more uniform finishing and less dependence on operator skill. Manual honing requires the mechanic to control movement and pressure by hand, being cheaper but with less consistent results. Hydraulic is faster, reduces operator fatigue and maintains quality standards, especially important in higher work volumes.

Honing uses abrasive stones mounted on a head that rotates and moves up-down inside the cylinder simultaneously. This movement creates the characteristic crosshatch pattern on the inner wall. The BHCN-140 automatically controls rotation speed and vertical movement via hydraulic system. The operator chooses stone grit according to desired finish. Process removes scratches from previous machining and prepares ideal surface for ring seating, ensuring proper compression and oil consumption.

As a hydraulic machine, it requires regular hydraulic oil changes and leak inspection on hoses and fittings. Honing stones need dressing or replacement according to wear. Frequent cleaning removes metal debris that could scratch future jobs. Checking head alignment periodically ensures precision. Being imported equipment, it's important to have a reliable supplier for replacement parts and specialized technical assistance when needed.
