Geometric Tolerancing for CNC Turned parts

Nine types of geometric tolerances with automated quoting and precise specifications in 0.01mm increments now available

CNC Turning Parts - Geometric Tolerance instant quote is now available

April 16, 2024 – meviy, the cutting-edge parts procurement platform developed by MISUMI Group Inc., has rolled out a significant enhancement: geometric tolerancing for CNC Turned parts. This latest addition further amplifies the platform’s capabilities, enabling customers to access nine types of geometric tolerances with a remarkable accuracy of up to 0.01 mm.

Recognizing the persistent challenges within the realm of high-precision parts procurement—ranging from protracted quotation processes to extended delivery lead times and price volatility—meviy initially introduced geometric tolerancing for CNC milled parts in October 2022. Building on the success and demand for this feature, the platform now extends its functionality to CNC Turned parts. This enhancement empowers customers to seamlessly specify geometric tolerances directly from their 3D data, facilitating instant quotations and expediting the procurement process with unparalleled efficiency.
