Wet Sleeve Seat Milling Machine FAC-86 Chinelatto 2.87-7.72 inches

The wet liner seat milling machine is used to mill and prepare the seats where wet liners fit into the engine block. It removes imperfections, oxidation and surface irregularities, ensuring perfect sealing between the liner and block. The FAC-86 works with liners from 2.87 to 7.72 inches (73 to 196mm), ideal for heavy diesel engines, Cummins and other wet liner engines, with 0.0004 inch (0.01mm) precision.

The FAC-86 milling machine has capacity to mill liner seats from 2.87 to 7.72 inches (73 to 196mm) diameter, with maximum milling depth of 0.98 inches (25mm). Features 0.0004 inch (0.01mm) micrometric graduation, electromagnetic base fixation and manual spindle rotation. Comes with 5 tools covering full range: 2.87-3.46 inches (73-88mm), 3.35-4.33 inches (85-110mm), 3.82-5.20 inches (97-132mm), 4.84-6.38 inches (123-162mm) and 6.22-7.72 inches (158-196mm). Weighs 13.9 lb (6.30kg) net.

Yes, the FAC-86 serves Cummins engines perfectly, including a specific tool holder shaft for Cummins blocks as optional accessory. The machine covers 2.87 to 7.72 inches (73 to 196mm) range, compatible with various heavy diesel engines including Cummins, Scania, Mercedes, Volvo and other trucks and tractors. For Scania D11/DS11 and D14/DS14 there's also optional grooving kit.

Manual milling machines like the FAC-86 have rotation and feed controlled by the operator, offering greater control and precision in specific jobs, plus lower cost. Automatic milling machines have electric motor and programmed feed, faster in serial production. Manual is more versatile for machine shops serving varied engines, allowing fine adjustment for each situation and requiring less maintenance.

Milling works by fixing the machine to the block through the electromagnetic base, which offers secure fixation without screws. The operator positions the appropriate tool for the liner diameter, adjusts depth using the micrometric ring and manually rotates the milling spindle. The magnetic base allows quick repositioning and work at different angles, powered by the 24V transformer included with the FAC-86.

FAC-86 maintenance is simple: regular cleaning of tools and guides, shaft lubrication per manual, checking electrical connections of transformer and magnetic base. Cutting tools should be sharpened periodically to maintain precision. Being robust Chinelatto equipment, with proper maintenance it has long service life in professional machine shops, being important to use only original parts.
