Diamond Connecting Rod Honing Machine BB-98 Chinelatto

The connecting rod honing machine is used for internal finishing of connecting rod bores, removing small imperfections and leaving the surface smooth and to the correct size for bearings. The BB-98 Chinelatto works with connecting rods from Ø1.61 to 3.86 inches (41 to 98mm) using diamond blades that guarantee professional precision. It's essential in engine rebuilding shops to return the connecting rod to original specifications after machining.

The BB-98 Chinelatto honing machine works with connecting rods from Ø1.61 inches to Ø3.86 inches (41mm to 98mm). It has a 1HP motor to rotate the honing spindle and runs on 220V three-phase. The machine measures 3.5 x 3.1 x 3.9 ft (1.07 x 0.95 x 1.19m) and weighs 639 lb (290kg). It comes complete with 3 blade holder spindles and 36 diamond blades included. This diameter range covers most car, truck and some industrial engine applications.

With capacity from Ø1.61 to 3.86 inches (41 to 98mm), the honing machine works on compact car, sedan, SUV, pickup truck and small to medium industrial engines. It covers from 1.0L engines up to V8s and some light diesel engines. The diameter range handles practically all engines that come into a typical machine shop. It's ideal for shops working on domestic and imported vehicles, guaranteeing professional finishing on connecting rods after rebuilding.

The diamond honing machine like the BB-98 uses blades with diamond application that last much longer and provide superior finishing compared to conventional abrasive stone blades. Diamond cuts better, generates less heat on the part and maintains precision longer. Additionally, it takes less time per connecting rod and leaves better surface finish. For shops doing volume work, it pays off through increased productivity and service quality gains.

Honing removes microscopic material from the connecting rod bore through diamond blades that rotate and make reciprocating movement. The BB-98 uses its 1HP motor to spin the blade holder spindle while the operator moves the tool up and down inside the bore. This creates a crosshatch pattern that ensures uniform finish and precise measurement. The process is quick and leaves the surface ideal for the bearing.

The diamond blades on the BB-98 last much longer than conventional blades - they can hone hundreds of connecting rods before needing replacement, depending on material and condition of parts. The machine comes with 36 blades included and 3 blade holder spindles. To maintain precision, it's important to use proper cutting fluid and not over-force the tool. Chinelatto offers technical support and replacement parts to keep the machine always running.
