High-precision D16 3D metal flat welding tables
This is a high-precision three-dimensional metal welding workbench
based on the D16 grid system. "D16" refers to the precisely
distributed holes on its surface, which have a diameter of Φ16mm
and a typical spacing of 50mm. It is made of high-strength metal
(usually high-quality alloy steel), and undergoes precision
machining and heat treatment to achieve exceptional flatness and
dimensional stability.

Key Features and Advantages
- Ultimate Precision Foundation:
Ultra-high flatness: The work surface undergoes precision milling
and stability treatment, achieving a flatness of typically
±0.025mm/m² or higher, reaching the level of a measurement
reference platform.
Micron-level hole position tolerance: The position tolerance of
each Φ16mm hole is controlled within ±0.01mm, ensuring unparalleled
repeatable positioning accuracy for fixtures at any position. - Refined D16 System:
Smaller hole diameter (Φ16mm) and denser hole spacing (50mm):
Compared to the common D28 system, it provides a denser array of
positioning points. This means you can use smaller, more precise
fixtures to perform finer and more complex positioning and clamping
of workpieces in a more compact space, especially suitable for
small, multi-featured workpieces. - Superior Materials and Craftsmanship:
High-quality metal substrate: Made of high-quality alloy steel,
possessing high rigidity, good dimensional stability, and thermal
stability.
Advanced surface treatment: The table surface is often ground,
scraped, or nitrided, not only guaranteeing flatness but also
giving the surface extremely high hardness (up to HV1000+ after
nitriding), making it super wear-resistant, scratch-resistant, and
corrosion-resistant, ensuring the initial precision is maintained
permanently. - Lightweight and Modular Design:
Although extremely precise, due to the use of steel and optimized
design, its overall weight is lighter than cast iron platforms of
the same size, making it easy to integrate into automated units or
precision workshops.
The matching D16 system fixtures are exquisitely designed, fully
functional, and also possess extremely high precision and rigidity.
Main application areas
- Aerospace: Welding and assembly of small engine components, flight
control units, and precision brackets.
- Precision Instruments and Optical Equipment: Manufacturing of
sensor housings, laser frames, and high-precision mechanical
components.
- High-End Automobiles and Racing Cars: Prototyping and small-batch
production of engine mounts, lightweight chassis components, and
precision transmission system parts.
- Medical Devices: Welding of surgical robot components and precision
structural components for imaging equipment.
- Semiconductors and Vacuum Chambers: Precision assembly of small
vacuum chambers and process chamber components.
- Scientific Research and Prototype Development: Serving as the
ultimate reference platform for validating designs and
manufacturing functional prototypes in laboratories or R&D
centers.
- High-Precision Robotic Welding Workstation: Acting as the workbench
for precision welding robots, ensuring perfect correspondence
between programmed trajectories and physical zero points.
Selection Guide
1. Workpiece Size Selection
Small precision parts (such as automotive parts, small aerospace
components): Choose worktables with dimensions of 500×500mm or
1000×1000mm, balancing precision and footprint.
Medium-sized structural parts (such as engineering machinery
frames): Choose dimensions of 1500×1000mm or 2000×1000mm,
supporting multi-part clamping.
Large workpieces (such as rail transit vehicle bodies): Multiple
small worktables can be spliced together, using splicing
plates/connecting bridges to enhance overall rigidity, which is
more cost-effective than directly purchasing an extra-large
worktable.
2. Material Selection
Cast iron (HT300): Good shock absorption, low thermal deformation,
suitable for high-precision welding scenarios, but heavy and
requires a forklift for handling, suitable for fixed workstations.
Steel (Q355/45# steel): High strength, lightweight, highly mobile,
suitable for multi-station workflow, but slightly less thermally
stable than cast iron, requiring the use of heat insulation pads.
3. Surface Treatment Selection
Nitriding treatment: High hardness, prevents welding slag adhesion,
long service life, suitable for high-frequency welding operations,
and is the mainstream choice.
Chrome plating treatment: Excellent rust resistance, suitable for
humid/dusty workshop environments, or projects exported to
high-humidity regions.
