About SIPENG CNC
Engineering-Driven CNC Manufacturing Solutions
SIPENG CNC provides application-driven CNC machine solutions built around each customer's parts, materials, tolerances and production requirements. We integrate machines, tooling, fixtures, programming, automation and engineering support into one coordinated solution.
An Engineering Company Built Around Your Parts
SIPENG CNC is an engineering-driven CNC solution provider. We begin with your part drawing, material, tolerance and production target, then determine the appropriate machine, tooling, fixture, programming and automation configuration.Through our network of specialized manufacturing partners and experienced engineers, we coordinate machine production, application engineering, inspection, commissioning and project delivery. Our goal is to provide a practical and reliable solution while helping customers reduce project complexity and control cost per part.

Learn MoreQuality Control Throughout the Project
Quality control is coordinated throughout drawing review, incoming component inspection, machine assembly, accuracy verification, test cutting and final pre-shipment inspection.

Every project starts with a documented review of the part drawing, material and tolerance requirements.

Chemical composition, hardness and dimensional checks on raw material and components before production.

In-process geometry, accuracy and balancing verification of machined components against drawing tolerances.

Assembly accuracy, geometry and spindle checks carried out during machine build and assembly.

Test cutting on customer-typical parts to verify real machining performance before shipment.

Final check of machine condition, accuracy records, documentation and accessories before packing and dispatch.
