16mm Holes Array Design Modular Welding Table

◆ Precision Hole Array Design:
◦ Hole Diameter: The standard hole diameter is 16mm (with extremely small tolerances).
◦ Hole Spacing: The common standard grid spacing is 50mm x 50mm. Higher-end models adopt a super-dense hole array of 25mm x 25mm, providing unparalleled clamping flexibility.
◦ High-Precision Machining: The positional tolerance of the holes (usually required to be ≤ 0.1mm across the entire table surface) and the consistency of the hole diameters are extremely high, which is the cornerstone of the precision of the entire system.
◆ High-Rigidity Dense Tabletop:
◦ Due to the small hole diameter, the proportion of solid metal is higher for the same tabletop size, resulting in excellent local rigidity and flatness retention of the tabletop, which is particularly suitable for supporting precision workpieces.
◆ Precision Accessory System:
◦ All supporting fixtures, positioning blocks, and support columns are designed based on the 16mm interface (usually using M10 or M12 fastening bolts).
◦ The accessories are characterized by being "small, precise, and compact". For example, micro quick clamps, fine-tuning locating pins, narrow-edge angle devices, etc., can be operated and arranged in very small spaces.
◆ High Positioning Accuracy:
◦ The small hole diameter means a smaller fit gap between the bolt and the hole wall, providing better initial positioning.
◦ Step pins, taper pins, or ball-head positioning systems are widely used, which can be directly inserted into the holes to achieve precise gap-free positioning (while the 28mm system relies more on side jacking to eliminate gaps), with theoretically higher positioning accuracy (up to ±0.05mm level).
