QSMB-3300/3700

The DINOSAW ZDDH-800/1000/1200 continuous calibrating machine levels stone slab thickness in a continuous pass, preparing slabs for polishing lines where a uniform base thickness decides final quality. Three grinding head diameters cover workshop to production-line duty, with optional worktable lengths to match the slab sizes being processed.

Automatic Profile Polishing Machine Applications & Materials

Profiled stone components are used in architectural finishing, interior fit-outs, and custom stone fabrication. This machine is intended for the polishing stage after the required edge shape has been produced.

Real Polishing Performance & Key Metrics

Grinding-Length Options

The catalog lists QSMB-3300 with a 3,300 mm grinding length and QSMB-3700 with a 3,700 mm grinding length, helping match the machine to the length of the intended workpieces.

Work-Envelope Choice

The listed maximum processing dimensions differ by model: 3300 × 1200 × 150 mm for QSMB-3300 and 3600 × 1500 × 300 mm for QSMB-3700. Check the drawing and dimension orientation with the supplier before finalizing the order.

Main-Engine Power

The catalog lists 7.5 kW for QSMB-3300 and 11 kW for QSMB-3700. Match power and machine configuration to the planned material, profile, and site electrical supply.

Bridge-Type Machine Layout

The bridge-type structure positions the polishing system over a dedicated work platform. This layout is intended for handling shaped stone workpieces during edge finishing; workpiece support and access should be reviewed against the parts being produced.

Model-Matched Grinding Length

The QSMB-3300 and QSMB-3700 provide catalog-listed grinding lengths of 3300 mm and 3700 mm. Matching the model to the longest routine workpiece helps avoid selecting by machine footprint alone.

Defined Workpiece Envelope

The catalog lists different maximum processing dimensions for the two models. Check the dimensions of the complete workpiece, including the profile projection and support requirements, before confirming the usable processing range.

FAQs

Compare the QSMB models, check profile and material compatibility, and prepare the key details needed for a quotation.
