Engineered for Dimensional Stability & Strict Compliance
Machining polymers requires precision handling distinct from metals. At PRECI5, custom cutting geometries and feed rates prevent thermal deformation.
Controlled Annealing Cycles
Pre-machining and intermediate batch annealing alleviate residual stress, stopping warpage during roughing and post-machining relaxation.
Specialized Polymer Cutters
Diamond-coated and polished-flute carbide tools create clean shearing actions without heat buildup, securing optical finishes and razor-sharp edges.
Cleanroom & Contactless CMM
Non-contact optical inspection avoids surface deflection during metrology, ensuring high-accuracy validation for medical and semiconductor parts.
