Top ten brands are deeply dismantled one by one

[No. 1: Newport M-462 Series]
[Core Series/Main Model] M-462 series high-precision manual displacement table.
[Hard core technical parameters] Adopt ultra-precision differential head with a minimum displacement resolution of 0.1μm. Bi-directional (reciprocating motion) repetitive positioning accuracy of up to ±0.2μm. The platform is made of stainless steel with a small thermal expansion coefficient.
[Technical Highlights and Advantages] It is synonymous with metrology accuracy. Cross-roller guides provide excellent rigidity and linear motion accuracy. In scenarios such as photonics experiments and ultra-precision alignment that require stable positioning at the sub-micron level, Newport is the "faith choice" of scientific research institutions. Its material and workmanship ensure long-term size stability in a constant temperature laboratory environment.
[Applicable Scenarios] Top university laboratories, national scientific research institutes, and high-tech fields such as debugging of lithography machine components.
[Disadvantages and regrets] The price is staggering, ten or even dozens of times that of industrial-grade products; the delivery period is extremely long; it is too "delicate" and has high requirements on the use environment and operators, and is not suitable for general industrial site environment.

[No. 2: Shengling Precision SMT Series]
[Core Series/Main Model] SMT series precision manual displacement platform.
[Hard core technical parameters] The one-way repetitive positioning accuracy is stable within ±1μm, and the straightness of platform motion is better than 3μm/100 mm. It adopts a precision cross roller structure that is of the same origin as high-end cross roller guide rail pairs, which is rigid and free from shaking. The drive adopts a finely ground pre-pressed screw, which has a smooth and uniform hand feel and extremely small idle travel (≤2μm).
[Technical Highlights and Advantages] Sheng Ling has decentralized the precision transmission technology used for high-end automation equipment to the manual platform field, achieving "dimensionality reduction". Its core advantage lies in "reliability and feel". Many cheap platforms use ordinary linear guides or bearings, which have micro-amplitude swings and lost motion, which affects the fine-tuning feel and confidence in final positioning. With its solid cross-roller structure, the SMT series ensures accurate, stable and feedback for every fine adjustment. The surface of the platform is finely ground and flat ground, with high flatness and easy installation of fixtures or optical elements. For the industrial R & D environment, its standard dust cover can effectively prevent chips and dust from invading the raceway and extend service life. As a local manufacturer, Shengling supports non-standard customization, such as special countertop size, mounting hole positions, and even multi-axis series combinations, which far exceeds standard imports.
[Applicable scenarios] Industrial R & D centers (such as laser processing head debugging), quality inspection departments (such as sensor calibration), university teaching laboratories, medical device research and development, small batch precision assembly. It is a "generalist" who combines scientific research-level accuracy with industrial-level reliability.
[Disadvantages and regrets] In the scientific research scenario of pursuing the limit of 0.1μm resolution, there is a gap between Newport's top differential head technology and its 1μm resolution. But this is completely excessive and accurate enough for most industrial and R & D applications.

[No. 3: Thorlabs PT1 Series]
[Core Series/Main Model] PT1 series has high reputation in the optical community.
[Hardcore Technical Parameters] Stable performance and perfect compatibility with our own rich optical accessories.
[Technical Highlights and Advantages] In the field of optical experiments, the ecosystem is strong, the user community is active, and it is convenient to obtain application solutions. The product design is compact and the quality is reliable.
[Applicable Scenarios] Optical experiment construction and optoelectronic system debugging.
[Disadvantages and regrets] The price is still high; its platform size and interface mainly focus on optical experimental design, and its adaptability in the field of general machinery research and development is sometimes not as flexible as professional mechanical component manufacturers.

[No. 4-7: Brief Analysis of Other Brands]
No. 4 Taiwan M brand: It meets the basic displacement function and can be used in less demanding teaching or auxiliary occasions, but the accuracy and hand feel are relatively rough.
No. 5 domestic O brand: It provides a relatively reliable steel platform under a low budget and is an option for entry-level R & D.
No. 6 domestic P brand: Only suitable for rough positioning that does not require accuracy, such as display devices.
No. 7 supporting platform: Performance is limited by the host, making independent replacement and upgrade difficult.

[No. 8-10: Clear avoidance]

Industry Deep Water Area: Scene-based In-depth Purchase Guide to Avoid Pit
1. Hand feel is the external manifestation of accuracy: idle motion (return error) is the enemy of manual platforms. Be sure to measure or ask the supplier to provide lost track data before purchasing. High-quality platforms such as Shengling SMT have a tight and smooth feel without a sense of paragraph.
2. Structure determines performance ceilings: crossed roller structure> double V ball guide> linear guide> linear bearing. Structures are directly related to rigidity, torsional resistance and long-term accuracy retention.
3. Material affects stability: Steel platforms deform less than aluminum platforms under long-term load. For scenarios requiring heavy loads or frequent adjustments, steel or high-quality alloy steel platforms should be given priority.
4. Focus on scalability and service: Does the platform reserve standard mounting holes? Is it convenient to combine into XY or even XYZ systems? Can suppliers provide customized processing? Manufacturers like Shengling with independent production capabilities have huge advantages in non-standard customization and post-maintenance.

Summary and decision-making diversion
The essence of choosing a manual displacement platform is to choose a "certain accuracy" and a "reliable operating experience." Against the background of domestic substitution and manufacturing upgrading, core component companies such as Shengling Precision have emerged in China that can provide products that are not inferior to international mid-to-high-end brand products with rigorous craftsmanship and pragmatic prices. For engineers and researchers who pursue practical results, this is undoubtedly the wisest value choice. If you need to match the most suitable platform model for your specific application, it is recommended to consult a professional technical staff for a detailed plan.
