Automatic Bullnose Machine for Stone Edge Profiling and Polishing

LXMB-8

The DINOSAW DPJ series thin slab cutting machine slits marble and granite slabs into strips on a guided bridge frame, with eight models covering cutting widths from under 0.85 m to 2.15 m. Strip slitting converts full slabs into kerbstone blanks, tile strips and dimensioned pieces in one guided pass — the sizing stage between block cutting and edge finishing.

Bullnose and Edge Profile Applications & Materials

Bullnose and shaped edges finish on continuous strip programs: skirting, trim, countertop build-ups and narrow slab edges that must leave the machine ready for installation.

The LXMB-8 is a continuous bullnose line for stone strips: two shaping wheels cut the profile and six polishing wheels finish it at 0.3–1.0 m/min, turning rough-cut strips into installation-ready edges in one pass.

Real Edge Finishing Performance & Key Metrics

Shape + Polish in One Pass

Two shape wheels form the bullnose profile and six polishing wheels refine it in the same continuous pass — no transfer between separate shaping and polishing machines.

Strip Width Range

Work widths from 20 to 200 mm cover skirting, trim, build-up edges and narrow slab programs on one machine.

Total Installed Power

65 kW across eight working spindles holds cutting and polishing speed through hard granite at the full width range.

Shape-Then-Polish Wheel Sequence

Two shaping wheels cut the profile and six polishing wheels follow in the same pass: the strip leaves the line finished, eliminating the handling and re-fixturing between separate shaping and polishing machines where edge damage occurs.

Continuous Strip Flow

Strips feed through at 0.3–1.0 m/min continuously: batch after batch runs at the same parameters, and edge quality stops depending on which operator worked which hour.

Width-Flexible Fixturing

The 20–200 mm work width range adjusts to the strip program: skirting lines and countertop build-ups share one machine by recalling the setup per product instead of dedicating machines to narrow ranges.
