4-CYLINDER Engine Block Table M-4C Chinelatto with Adjustable Vise

An engine block clamping table is used to securely hold blocks and sleeves during grinding operations. The M-4C Chinelatto table is specific for 4-cylinder engines, allowing safe part fixation through the adjustable clamp. It includes specific rings for VW 1300/1500/1600 and Corcel I/II engines, plus bases for CB 400, CG 125/200 and XL 250 motorcycles. It's essential for ensuring precision in grinding work, preventing vibration and part movement during machining.

The shim that comes with the M-4C table has dimensions of 2.44 x 2.05 x 9.17 inches (62 x 52 x 233 mm). This shim is part of the standard accessories included with the table and is important for correct positioning and leveling of blocks during fixation. The specific dimensions ensure the part stays at proper height and position for grinding work. The shim works together with the adjustable clamp to provide secure and precise fixation of the engine block or sleeve.

The M-4C table comes with specific rings for different engines. For Volkswagen, it includes ring for VW 1300 and another for VW 1500/1600, plus specific reduction bushing. For Ford, it has ring for Corcel I and another for Corcel (general), with reduction bushings for Corcel I and II. For motorcycles, it includes guide bases for CB 400, CG 125, CG 200 and XL 250. Each ring and base are dimensioned specifically for the diameter and characteristics of each engine, ensuring proper fixation.

The main difference lies in usage flexibility. Table with fixed clamp only accepts blocks of one specific dimension, limiting the types of engines that can be worked on. The table with adjustable clamp, like the M-4C, allows adjusting clamp height and position according to block size. This enables working with different engines using appropriate rings. The height adjustment support that comes with the M-4C offers versatility to handle various types of blocks and sleeves in a single table.

The system works through combination of adjustable clamp, support rings and specific bases. First, position the appropriate ring for the engine (VW or Corcel) on the table. The block or sleeve fits into the ring, which serves as guide and support. The adjustable clamp is set to correct height using the adjustment support, firmly pressing the part against the table. The tightening wrench that comes with the equipment allows applying necessary torque for secure fixation throughout the entire grinding operation.

The M-4C table requires basic maintenance to ensure precision and durability. Always keep clean, removing chips and debris after use. Periodically lubricate clamp threads and adjustment points. Check component tightness regularly. Store in dry location to prevent oxidation. Rings and bushings should be inspected for wear, as they affect clamping precision. With proper use and basic maintenance, it's durable equipment. Chinelatto offers technical support and parts replacement when necessary.
