Block Trimming Wire Saw Machine for Stone Block Trimming

It keeps the wire in its efficiency window as cutting resistance changes. Stone hardness, wire wear and cut depth all change the load on the wire through a pass: a single fixed setting either under-feeds and wastes time, or over-feeds and glazes, deviates or breaks the wire. The BXSJ's double inverter system regulates wire speed and feed together, matching the drive to the actual resistance in real time — the catalog describes this as ensuring the best cutting efficiency of the diamond wire, and in practice it shows up as steadier cut progress, longer wire life and fewer wire failures mid-pass. Operators still set the working range per stone class, but the system holds the wire inside that range instead of drifting out of it. The 22 kW drive gives the system torque headroom to hold the working range even as the wire dulls through a shift. Rail segments store flat on the service truck, which keeps the whole system genuinely portable.

Match the options to your work pattern. The laser alignment device pays for itself when trimming several faces per block or repositioning frequently: optical referencing replaces repeated manual measuring and speeds every setup. The mid-rail guide wheel unit extends pass length beyond the standard 2-metre rail — add it when your blocks regularly exceed one rail position. The +10° manual tilt aligns the cut to sloped quarry floors and uneven block faces; if your blocks come off irregular benches, this is the difference between following the intended plane and following the ground. The BXSJ-22PM's 0–40 m/s speed range suits higher-specification wires and harder stone — standard granite and marble trimming runs well on the base BXSJ-22 at 0–30 m/s. Tell DINOSAW your typical block sizes and stone classes and the configuration comes back matched. The base 0–30 m/s model covers most granite and marble trimming; the PM variant's wider speed range suits shops running multiple wire specifications.

Yes — the 22 kW main drive and inverter-controlled feed cover granite, marble and dimension stone blocks on the same machine, with per-stone parameters. Granite trims at controlled feed with wire specifications matched to hard, abrasive material; marble trims faster with finer wires that protect the surface. Two working rules transfer across stones: set the wire speed inside the manufacturer's range for the wire you are running — the 0–30 or 0–40 m/s range is a capability window, not a target — and keep water continuous at the cut, because dry or starved cutting shortens wire life sharply regardless of stone. Track meters per wire per stone class so the life baseline stays meaningful: granite will sit at a different number than marble, and both numbers are correct for their material. Track wire life per stone class: granite and marble will show different baselines, and both are correct for their material.
