HLSD-1525-1 CNC Stone Carving Machine

HLSD-1525-1 CNC Stone Engraving Machine
CNC Stone Engraver For Gravestone, Memorial, Signage & Relief Carving

Features

We used to say no a lot.
I have walked through enough memorial shops to notice the same thing over and over. The shop owners buying a stone engraver are almost never the ones who cannot carve. They are the ones who can handle simple marking - except the high-value memorial jobs where one mistake ruins the whole stone.

"Can you engrave sharp lettering on granite?" We can, but hand chiselling risks slips. "What about deep raised text?" Hard to keep uniform. "This relief takes hours, what if power cuts out halfway?" Sorry.
Every one of those "sorry" is a customer walking into the shop down the road.
And that is the honest reason to buy this engraver. It is not about speeding up your simple routine marks. It is about the delicate memorial work you currently turn away.

How it actually engraves
The HLSD-1525-1 is controlled by NCStudio with a large colour display, performing engraving, drilling, lettering and cutting. Compatible with marble, granite, quartzite, sandstone, artificial stone, ceramics and glass. Workbench size is 1500 × 2500 mm, 410 mm gantry height and feeding height up to 360 mm - enough clearance for thick slabs and raised lettering, customizable if you process extra-thick stone.
No shaky hand tools. Precise CNC carving keeps text, portraits and relief patterns clean and repeatable for memorial production.

Power failure risk - and why break-resume matters
Anyone running memorial relief jobs knows long cycle times. A detailed monument relief can run for hours. When power drops, most machines force you to restart from zero or home to a reference point that no longer aligns with the stone.
The HLSD-1525-1 continues carving from the break point once power returns - break-resume function. If you have ever scrapped a half-finished headstone due to power outage, you already know how valuable this feature is.
Automatic lubrication system handles routine maintenance for stable long-hour operation.

Rigidity and accuracy for unforgiving granite
Granite is hard and brittle, so frame stability cannot be compromised. It adopts low-centre-gravity steel tube bed, keeping the machine stable at rapid traverse up to 30,000 mm/min. Positioning accuracy ±0.03 mm, repeat accuracy ±0.02 mm, equipped with Taiwan guide rails, ballscrew and rack on X, Y and Z axes.
The table uses aircraft-grade surface-oxidized aluminium profile topped with thickened PVC board, maintaining reliable loading capacity under frequent slab loading and unloading.

Spindle choice: match power to your job
Select the spindle according to your work, no overpaying for unused power. Three water-cooled spindle options: 3.7 kW / 4.5 kW / 5.5 kW, speed 6,000–24,000 rpm, tools from ø1 mm to ø16 mm.
Shallow relief and fine lettering work well on smaller spindles. Shops cutting sink holes and shower trays in engineered stone should choose higher power. Professional vector-control inverters stabilise speed under load and reduce power consumption.

One machine, two income streams
Purchased primarily for memorial work, it does not sit idle between tombstone orders. It also supports die making and signage jobs: copper sculpture, aluminium engraving, metal moulds, plastic sheeting and PVC.
Memorial shops fill idle time with signage and mould projects to improve machine utilisation and gain extra profit.

Where this engraver is not the answer
Being straight with you - this is a flat-bed machine. If your core work is full 3D carving on rotating workpieces such as statues, columns and balustrades, we have dedicated rotary models in our range.
This flat-bed engraver earns its place when you produce memorial lettering, portrait relief, signage and moulds, and every finished piece needs stable, consistent detail.

Who this is for
Gravestone and memorial shops for lettering and monument relief. Stone fabricators processing artificial stone and decorative slabs. Sign and mould makers working copper, aluminium, plastic and PVC.
If many enquiries end with "we cannot risk this job", this machine removes that limitation.
Send us the stone type, engraving depth and slab size you run most. We will confirm the suitable spindle and table configuration - including three alternative workbench sizes if 1500 × 2500 mm is not the footprint you need. No point selling you a machine mismatched to your workflow.
