Connecting Rod Cap and Bearing Grinder RSP-1 Chinelatto 2HP

The connecting rod cap grinder is used to correct deformations and wear on connecting rod caps and engine bearings. When the engine works for a long time, these parts can warp or go out of specification. The RSP-1 Chinelatto removes material with 0.001 inch (0.025mm) precision, leaving the surface smooth and within original specifications. It's essential equipment in shops that do complete engine rebuilds, ensuring proper clearance between connecting rod and crankshaft.

The RSP-1 grinder has an 8 inch (203mm) grinding wheel spinning at 3,440 rpm, with 2HP motor at 220V three-phase. Feed graduation is 0.001 inch (0.025mm), ensuring cutting precision. It weighs 110 lb (50kg) net and measures 24x16x28 inches (60x40x70cm) in packaging. Comes with straight 8-inch grinding wheel included. It's a compact but robust machine, ideal for small and medium shops needing professional precision in connecting rod and bearing grinding.

The RSP-1 grinder works with connecting rod caps and bearings from various engine types - passenger cars, pickup trucks, industrial engines and even some small trucks. The 8 inch (203mm) grinding wheel allows grinding parts of varied sizes. The 0.001 inch (0.025mm) precision serves both domestic and imported engines. It's versatile for shops serving mixed fleets, from 1.0L engines to medium-sized engines, as long as the connecting rod cap fits on the machine's work table.

Manual grinders like the RSP-1 require the operator to control feed and part positioning, giving more control over the process. Automatic ones make the feed by themselves through CNC command. Manual is cheaper and allows fine adjustments during work - ideal when each connecting rod may have different wear. Automatic is faster in serial production. For small and medium shops, the RSP-1 manual offers better cost-benefit and flexibility.

The process on the RSP-1 starts by securing the connecting rod cap on the machine table, aligning with precision. The grinding wheel spins at 3,440 rpm while the operator gradually advances in 0.001 inch (0.025mm) steps, removing deformed material. The cut must be uniform, always with coolant to prevent overheating. After each pass, the part is measured until reaching the correct dimension. Final finishing leaves a smooth surface for perfect fit of the new bearing shell.

The RSP-1 Chinelatto is a robust machine that lasts years with simple maintenance. Main care: change grinding wheel when worn, keep shafts lubricated and clean grinding dust after use. Check table alignment periodically to maintain precision. The 2HP motor is reliable, but needs cleaning of electrical contacts. With proper use, it serves shops for over 10 years. Replacement parts are easily found in the market.

The RSP-1 is quoted on demand, and pricing varies with each customer's needs, including accessories, tooling and optional features.
