Straight Line Engineering, Nelson, Lancashire
Established in 1979, Straight Line Engineering is a leading supplier of precision tooling for any hot or cold forming process. Allied but not limited to the aerospace industry, they have experience in the design, project management and manufacture of many forms of impression based tooling.
Servicing companies in high-precision industries such as aerospace places special demands on suppliers to deliver exacting quality standards. Straight Line were experiencing issues with the surface finish on components and reduced tool life, which they thought was down to the performance of their existing ER Collet chucks, and invited NIKKEN to investigate and provide a solution.
NIKKEN, together with engineers from Straight Line, quickly identified an application where this was particularly apparent and set about addressing the issues. Forming tool components being machined were suffering from inaccurate profiles and sub-standard surface finish, being caused by tool deflection due to the poor performance of existing ER Collet Chucks. This became apparent before the Carbide cutting tool life had expired, resulting in the need to replace cutting tools way before necessary. To overcome the issues with the finish, components had to undergo an additional flat honing, blending and polishing process to meet production tolerances, which increased production time and reduced efficiency.
