In the integration stage of ultra-precision equipment, the failure of many measurement systems to reach the expected final accuracy is not caused by insufficient precision of individual components, but by cumulative deviations continuously superimposed during the assembly of multiple parts. The traditional method separately processes the base, rail mounting seats and positioning reference blocks, and then assembles them by bolts. Errors in flatness and position tolerance of each joint surface will be passed on layer by layer, and eventually amplified at the whole machine level, which seriously affects coordinate measurement, optical scanning and precision detection results. The core idea of integrated machining high-precision measurement platforms is to break the error transmission chain of split machining. ZHHIMG cuts down assembly cumulative errors at the source through integral substrate forming and one-setup integrated fine grinding technology, providing low-deviation reference carriers for precision equipment.
The core advantage of integrated machining lies in reducing the number of assembly joint surfaces. A split structure is composed of multiple independent components. Each splicing introduces new error sources: fitting gaps between plates, uneven pre-tightening force of fasteners, and micro-deformation after stress release of parts will form cascading deviations. The integrated platform uses a single block of high-density substrate for overall machining and removes unnecessary splicing interfaces. The base, positioning references and module mounting surfaces are integrally formed on one blank. Relying on the excellent structural stability of ZHHIMG® black granite, the internal stress of the whole stone is fully stress-relieved, and it will not deform slowly after assembly like multi-piece spliced parts. In addition to granite solutions, integrated substrate options such as ceramics, mineral castings and UHPC are available for lightweight and special load scenarios to balance rigidity and low deformation.
The continuous machining process with one-time clamping locks the positional relationship among multiple references. In split machining, each part needs to be positioned on the machine separately. Each clamping will generate new positioning errors. After repeated clamping, it is difficult to guarantee the relative positional accuracy between references. For the integrated machining solution, milling and grinding of all key reference surfaces, mounting hole groups and positioning grooves of the platform are completed under the same set of tooling and one-time clamping. Whether it is the base of a long-travel linear motor sliding table, or the whole machine base for AOI optical inspection and CMM coordinate measuring machines, all mounting features on the platform share the same original reference coordinate system. The geometric tolerances of hole positions and base surfaces will no longer be disturbed by repeated disassembly and assembly. Large integrated components can be processed by the company’s large-travel CNC equipment to meet the integrated forming requirements of 20-meter ultra-long single workpieces and avoid forced sectional splicing of long platforms.
Integrated forming does not mean ignoring assembly requirements, but reconstructing assembly logic and simplifying on-site integration workload. Many customers confuse “integrated platform” with “non-assemblable platform”. The integrated platform retains standardized high-precision mounting interfaces. Cameras, linear motors, optical gratings and motion modules can be directly fixed on the integrally formed reference surface without additional transition plates and adapter bases. Fewer adapter parts mean fewer error links. Pre-inspection and pre-assembly verification are completed in a constant-temperature, constant-humidity and dust-free workshop to verify the geometric accuracy of all mounting references in advance. Customers only need simple alignment and fixing on site, greatly reducing secondary deviations caused by on-site commissioning. The shockproof structure and silent hoisting system of the workshop ensure that large integrated components will not be disturbed by micro-vibration during processing, transportation and inspection, protecting the precision reference surfaces that have been finished. 
Full-chain metrological inspection verifies the reference consistency of integrated platforms. Integrated components are large in size and rich in features, bringing higher detection difficulty than small measuring tools. A full set of traceable precision measuring instruments must be adopted. ZHHIMG uses imported measuring instruments such as laser interferometers, electronic levels and micrometer gauges to perform full-area scanning inspection on the whole working surface and all mounting features of integrated platforms in accordance with global metrological standards including DIN, ASME and GB, to confirm that the geometric accuracy of all references under the same coordinate system and there are no hidden deviations. Technicians with decades of grinding experience predict material stress changes during the machining stage, carefully control the aging and grinding procedures of integrated blanks, and stably control the overall flatness and position tolerance at nanometer and micrometer levels.
Integrated measurement platforms are widely applied in semiconductor inspection, precision laser equipment, new energy detection, high-precision XY motion platforms and other scenarios. Adhering to the corporate philosophy of openness, innovation and integrity, ZHHIMG continuously optimizes integrated forming technology through technical cooperation with global universities and metrological institutions. By reducing spliced structures and eliminating errors from repeated clamping, cumulative assembly deviations are minimized to the greatest extent. It enables the design accuracy of the whole set of precision equipment to be truly realized, helping customers reduce the difficulty of whole machine commissioning and improve the long-term operation stability of equipment.
