APR ENGINEERING TECHNOLOGIES PVT LTD
Precision tooling solutions for smarter CNC and robotic manufacturing.
APR supplies advanced Gravostar tooling solutions for automated deburring, contour compensation, and process-stable production across demanding manufacturing environments.
Gravostar product range
Automated deburring for undefined edges, contour variation, and production repeatability.Selection before supply
Tooling decisions that feel controlled from the first workpiece.
APR helps manufacturers move deburring from a manual uncertainty into a defined production step, with tooling choices based on geometry, machine type, and repeatability.
Study the edge condition
APR reviews material, burr direction, part geometry, tolerance variation, and access constraints before recommending a tool family.
Match the compensation style
Radial EC, axial LC, Colibri, ESP, or special tools are selected around the way your component actually varies in production.
Support repeatable production
The goal is less manual finishing, clearer wear-item planning, and a process that operators can trust shift after shift.
Industrial tooling support from selection to implementation.
