dispensing precision1. The Frame Is the Foundation of Precision。

While working, the XYZ axes drive the valve in fast, frequently reversing moves; every acceleration produces reaction force. The frame's job is to 'absorb' these forces and keep the axes steady. A rigid frame stays stable at high speed with true dispensing paths; a flimsy one shakes as speed rises and glue lines drift. Whatever effort a manufacturer puts into frame materials and structural design shows up in real machine performance. Learn more

2. Marble Platform: The Stability Choice for High-End ModelsCore Technologies。

Among frame materials, the marble platform is the recognized high-end solution. Marble is naturally

high-rigidity, low thermal expansion and well-damped— deformation from temperature change is minimal, ideal for precision dispensing. The Boli BL-JS531 local vision dispensing machine uses a marble table structure; its spec sheet lists ±0.02mm accuracy — the only model in the Boli line with an explicit accuracy figure. For customers with extreme precision needs, marble-platform models are the clear direction.3. Slide Structures: Embedded vs. Steel-Body

The key part carrying the motion axes on the frame is the ball-screw slide; its structure directly affects load capacity and service life. Boli uses Xinsheng (Shenzhen) precision screw slides in two families: the embedded SGTH series — compact, for normal loads — and the steel-body SKK series — stronger rigidity and load capacity, for large-travel heavy-load models.

4. How Frame Structure Maps to Selection

Frame structure essentially sets a machine's tier. For standard volume production, an embedded screw slide with aluminum frame fully meets needs at great value; for large products, long travel and heavy loads, steel-body slides guarantee rigidity; for extreme precision, consider marble-platform models. When buying, ask three things: what frame material, which slide structure, and whether the brand and model can be found in the BOM — these determine how long and how steadily the machine runs.

The frame is the physical basis of dispensing precision: marble platforms offer high rigidity and low thermal deformation for extreme precision — the Boli BL-JS531 reaches ±0.02mm; slides divide into embedded SGTH and steel-body SKK series for normal and heavy loads respectively. Checking frame material, slide structure and the BOM list at selection beats comparing spec numbers. Learn more
