Portable Cylinder Boring Machine BVC-130

A cylinder boring machine is used to machine and enlarge engine block cylinders when they're scratched, out-of-round, or worn. The process removes material from internal walls, leaving smooth surface with uniform diameter. The BVC-130 works with cylinders from 2.64 to 5.12 inches (67 to 130mm) diameter, machining up to 13.19 inches (335mm) depth. It's essential equipment in engine shops for rebuilding blocks that cannot be just honed, allowing installation of oversized pistons.

The BVC-130 has a 0.75hp motor with 220V three-phase power and dual rotation speeds: 380 and 265 rpm. The transmission system uses gears and pinions, ensuring constant torque. Feed rate varies between 1.06 and 1.50 IPM (27 and 38 mm/min), with cutting precision of 0.0035 inches (0.09mm) per revolution. This configuration allows working different cast iron and aluminum types, adapting rotation speed based on material hardness and cutting tool type used.

The boring machine works with cylinders from 2.64 inches to 5.12 inches (67mm to 130mm) diameter, covering from small motorcycle engines to V8 blocks from large cars. Maximum depth is 13.19 inches (335mm), sufficient for most automotive blocks. Comes with 6 centering pin sets (3 pieces each) to secure different block sizes. It's ideal for shops servicing domestic, imported cars and some larger displacement motorcycles, eliminating the need to outsource boring work.

A portable boring machine like the BVC-130 comes to the block, mounting on it with support fixtures, ideal for heavy blocks or when there's no overhead crane. Stationary boring machines require bringing the block to them. Portable has advantages in small shops (space saving) and large blocks (V8, truck engines). However, stationary machines generally offer greater rigidity and precision. The BVC-130 compensates with good precision (0.0035 inches/0.09mm per revolution) and easy setup.

The process uses a rotating cutting tool that removes material from cylinder walls. The BVC-130 centers on the cylinder with locating pins, the tool rotates and advances simultaneously cutting 0.0035 inches (0.09mm) per revolution. Manual lubrication system reduces heat and improves surface finish. Included micrometer measures diameter in real time. After boring, cylinder needs honing for final surface texture. Allows increasing diameter for oversized pistons, rebuilding engines with worn cylinders.

Basic maintenance includes cleaning after use, gear lubrication per manual, and tool sharpening with diamond stone (included). Check alignment periodically and replace worn cutting tools. With proper use and maintenance, Chinelatto equipment lasts decades in shops. Gear transmission is more durable than belt drives. Main wear items are cutting tools and bearings. Technical support available and replacement parts facilitate long-term maintenance and keep the machine productive for years.

The BVC-130 is quoted on demand, and pricing varies with each customer's needs, including accessories, tooling and optional features. With in-house technology developed by Chinelatto in Brazil since 1962, you can count on responsive support from our technical team.
