Iscar 4550288 Boring Head Sliding Block Mb Series

Product Description

The ISCAR 4550288 is a sliding block designed for use with fine boring holders in precision machining applications. It serves as a positioning and adjustment component within a boring head assembly, allowing machinists to achieve accurate bore diameters by sliding and locking the block at the required radial offset. The block measures 92.99mm overall length, 24.99mm thick, and 30.51mm wide. Weighing approximately 0.05 pounds, this compact component is machined to close tolerances to maintain repeatability during fine boring operations. It is a direct replacement or spare part for existing setups running compatible boring head systems.

This sliding block is intended for use in fine boring holder assemblies on CNC machining centers and manual boring mills. It is compatible with the Itsbore system and the MB series boring head platform. Typical applications include precision diameter work in aerospace, die and mold, and general metalworking environments where bore finish and dimensional accuracy are critical. Tooling technicians and machinists performing boring head maintenance or upgrades will find this block a necessary spare for keeping fine boring assemblies operational.

Compatibility

Compatible with Fine Boring Holders in the Itsbore system and MB series boring head assemblies. Verify block pocket dimensions against the target boring head before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with precision boring head assemblies. Power down and lock out the spindle before removing or installing any boring head components. Use appropriate torque-limited fasteners as specified by the boring head manufacturer documentation. Do not force the sliding block into the pocket; confirm dimensional fit and cleanliness of mating surfaces before assembly.
