Cylinder Boring Machine BCP-165 - 3.15 to 6.3 inches Industrial

The cylinder boring machine is used to machine and restore automotive engine cylinders that are worn, scratched or out-of-round. The BCP-165 works with cylinders from Ø3.15 to Ø6.30 inches (Ø80 to Ø160mm), allowing recovery of car, motorcycle and industrial engine blocks. The process removes damaged material from the cylinder's internal surface, leaving it with correct dimensions and finish to receive new pistons and rings. It's essential equipment for machine shops doing complete engine rebuilds.

The BCP-165 boring machine has capacity to machine cylinders with diameter from Ø3.15 to Ø6.30 inches (Ø80 to Ø160mm). This range covers most popular car engines, large motorcycles and some industrial engines. The equipment is imported and designed for professional use in machine shops and specialized workshops. Being an industrial machine, it offers precision necessary for work requiring strict tolerances. Technical specifications may change according to product evolution.

With the Ø3.15 to Ø6.30 inches (Ø80 to Ø160mm) capacity of the BCP-165, you can work on domestic and imported car engines, medium and high displacement motorcycles, small marine engines and some industrial engines. This includes 1.0 to 2.0 liter engines in most cases, some V6 and light diesel engines. The range serves well machine shops working with diversified fleets. For very small engines (125cc motorcycles) or very large ones (heavy trucks), you would need equipment with different capacities.

The boring machine like the BCP-165 does initial roughing, removing material to correct out-of-roundness and deep scratches in cylinders. The honing machine does final finishing, creating the crosshatch pattern necessary for ring lubrication. They are complementary processes: first you bore to correct dimensions, then hone for finishing. The boring machine works with greater material removal, while honing machine removes only a few thousandths for surface texturing.

The process uses a cutting tool (special boring bit) that rotates and advances inside the cylinder, removing material from the internal wall. The block stays fixed on the BCP-165 machine table while the tool makes precise rotation and translation movements. The operator adjusts cutting depth according to original cylinder wear. The result is a cylinder with uniform diameter, without out-of-roundness, ready to receive oversized piston or to be honed as final finishing.

Basic maintenance includes regular chip cleaning, bearing and guide lubrication per manual, tool alignment verification and periodic machine calibration. Since the BCP-165 is imported equipment, use original parts when possible. Change cutting tools when they lose their edge, keep cooling system clean and check guide clearances regularly. Proper preventive maintenance ensures work precision and long service life of the industrial equipment.
