Stone CNC Engraving Machine FSM1313
Stone is not wood with a harder surface. It needs a high-torque spindle that holds cutting force, a frame that does not shake, and water — both to keep the cutter cool and to keep silica dust out of the air. The FSM1313 is built around all three, with a 1300 by 1300 mm table, a 5.5 kW constant power stone spindle and a water tank, for lettering, relief and monument work in marble, granite, ceramics and glass.

Overview
A Stone Machine, Not a Wood Router With a Different Bit
Three design decisions separate a stone engraving machine from a general-purpose router.
Constant Power Spindle
A 5.5 kW constant power stone spindle keeps cutting force steady as the load changes, which suits the variable hardness found inside a single block of granite.
Rigid Cast Structure
A cast steel gantry, side supports and table on a vibration-aged T-steel frame, with imported square linear rails and multi-row blocks.
Water Tank and Cooling
A water tank and bidirectional tool cooling system cool the cutter and suppress dust, which protects both the tool and the operator.

Granite, Marble and Ceramic: Depth and Method
The same machine, but the method changes with the stone. Hard stone is taken in layers; soft stone goes deeper in one pass.

Tool Cooling
Water In, Dust Down, Tool Cool
Stone cutting removes a lot of material at high pressure, and it produces two things a machine has to deal with: heat at the tool edge and silica dust in the air. One water circuit handles both.
- Bidirectional tool coolingCoolant is directed at the cutter from front and back, so the tool stays at working temperature through a long carving pass.
- Constant power motorA constant power spindle motor keeps cutting force high and efficient even as the load varies through the stone.
- High swarf clearanceA large-bearing horizontal torque spindle with generous clearance lets the cut slurry clear instead of packing around the tool.
- Integrated water tankThe machine carries its own water tank, so the cooling circuit is part of the build rather than an accessory added later.

FAQ
Stone CNC Engraving Machine FSM1313 Questions
Depth depends on the stone. Hard stone such as granite is engraved in layers, so a 5 mm depth is reached through successive passes. Softer stones such as marble and bluestone can be engraved 5 mm deep in a single pass. The same tooling also works on jade, crystal, agate, glass and ceramics, though the feeds are set per material.
Two reasons. Water keeps the cutter cool, which matters because stone cutting generates a great deal of heat at the tool edge and a hot cutter loses its hardness quickly. Water also suppresses the silica dust that stone machining produces, which is a health hazard if it becomes airborne. The machine is built with a water tank and a bidirectional tool cooling system to do both jobs.
Stone lettering, relief carving, positive carving, edge grinding, line carving, cutting and hollowing out. It is used for engraved lettering and calligraphy, art reliefs, monument and memorial work, decorative building elements and ceramic processing, and it comes with a full set of carving tools including cutters for relief work.
The table is a welded T-steel structure that is vibration aged, and the gantry, side supports and table are cast steel. Imported square linear guideways with dual-row and four-row blocks carry the axes, which gives high load capacity, fast movement, smooth running and long life. The result is a machine that runs without noticeable shake, which is what produces a high surface finish on stone.
The spindle is a 5.5 kW constant power stone spindle running at 24,000 rpm with an ER25 collet, with large bearings and high swarf clearance so the motor is not easily damaged. X and Y are driven by German helical rack and pinion and Z by a TBI ball screw, all running on HIWIN or THK linear rails.
The control includes breakpoint memory, so the job can resume from where it stopped after an unexpected interruption rather than starting again. That is useful on long stone carvings where a broken cutter or a pause overnight would otherwise waste the whole piece. Main components carry a two-year warranty.
