Entry-Level Stone Letter Engraving Machine for Tombstones & Name Plates
View DetailsA stone engraving machine is the equipment that turns a plain block of granite or marble into a finished monument, tombstone, name plate or decorative panel. From a family's memorial inscription to a temple's carved facade, the quality of the final engraving sharpness of lettering, depth consistency, portrait realism depends directly on the machine doing the carving.
As a leading stone engraving machine manufacturer in India, K.S. Malviya Industries builds a focused range of CNC stone engraving machines from the entry-level KCM-800 for basic lettering, to the PEM-3020 2D/3D/4D for full photo-realistic portrait engraving, and the high-output ACM-3015 2Q for monument manufacturers running large daily volumes. Our customers include monument and tombstone manufacturers, memorial stone fabricators, marble and granite processing units, and architectural stone suppliers across India.
Every stone engraving machine in our range is manufactured at our facility in Rajasthan, supported by in-house engineering teams and backed by direct technical service giving you a single point of contact for design support, installation and after-sales spares.
A stone engraving machine also known as a stone carving machine, stone marking machine or CNC stone router is a computer-controlled system that cuts text, images and patterns into the surface of granite, marble and other natural stone. A diamond or carbide-tipped engraving bit moves along toolpaths generated from a design file, removing stone material to a programmed depth.
Depending on the machine and the design, the result can be a flat 2D engraving (uniform-depth lettering and outlines), a 3D relief carving (varying depth to create raised or sunken effects), or a 4D portrait engraving, where depth and tool density are varied across thousands of points to reproduce a photograph as a lifelike image in stone the technique used for memorial portraits on tombstones and monuments.
Common applications include monument and tombstone inscriptions, memorial portraits, name plates and address plaques, religious motifs and temple carvings, decorative borders, and architectural stone signage for buildings, gates and facades.
Our CNC stone engraving machines are deployed across monument manufacturing, memorial stone production and architectural stone work wherever precise, repeatable carving on granite and marble is required.
Monument manufacturers use our stone engraving machines to cut names, dates, epitaphs and decorative borders into granite and marble tombstones with consistent letter depth and a clean finish across every order.
The 4D engraving capability of the PEM-3020 reproduces photographs as lifelike carved portraits on memorial stones a service increasingly requested by families and monument retailers across India.
Home, office and apartment name plates are among the highest-volume engraving jobs for small stone workshops. Our compact machines like the KCM-800 and DEM-2536 2D handle this efficiently in batch production.
Building entrance signage, gate plaques, foundation stones and corporate signage in granite or marble require sharp, durable lettering. CNC engraving ensures consistent letterforms across large signage panels.
Temples, religious institutions and idol manufacturers use stone carving machines for repetitive decorative motifs, scripture inscriptions and ornamental borders on marble and sandstone elements.
Stone exporters and decorative stone suppliers use 3D carving to produce relief murals, decorative wall panels and ornamental inlay designs for hospitality and residential interiors.
Four models covering entry-level lettering to advanced 4D portrait engraving and dual-head high-output carving matched to your production output, design complexity and stone type.
The PEM-3020 is our flagship stone engraving machine, capable of 2D lettering, 3D relief carving and 4D photo-realistic portrait engraving on granite and marble. It is purpose-built for monument manufacturers and memorial stone businesses that need to combine inscription work with lifelike portrait carvings on the same machine. The 4D mode converts photographs into depth-mapped toolpaths, producing carved portraits that retain facial detail and tonal gradation a capability that sets memorial stone suppliers apart in a competitive market.
View DetailsThe ACM-3015 2Q is built for monument manufacturers and stone processing units that need high daily throughput. Its dual-head configuration allows two engraving operations to run simultaneously for example, lettering on one tombstone while a decorative border is carved on another cutting overall cycle time for batch production. The machine handles deep relief carving on granite and marble, making it suitable for both high-volume lettering work and more demanding decorative carving orders.
View DetailsThe DEM-2536 2D is a compact, 2D-focused stone engraving machine with a working table sized for standard tombstone and name plate dimensions up to 2500 x 3600 mm. It is the practical choice for small to mid-sized monument workshops that primarily run lettering, dates and simple emblem work, without the added cost of 3D or 4D capability. Its simpler control system also makes it easier for new operators to learn and run independently.
View DetailsThe KCM-800 is our entry-level stone letter engraving machine, designed for workshops taking their first step from hand-carving to CNC production. It is well suited to tombstone inscriptions, name plates and small-format monument lettering, offering reliable, repeatable engraving on granite and marble at a lower capital investment than our larger models without compromising on lettering precision.
View DetailsThe KCM-800 is the right starting point. It gives a small monument or stone workshop reliable CNC lettering on granite and marble at an accessible cost, helping you move away from manual engraving without a large initial investment.
If your workshop processes a steady volume of tombstone inscriptions, name plates and simple emblems, the DEM-2536 2D offers a larger working table and dependable 2D engraving suited to consistent daily output.
If your customers request photo-based memorial portraits alongside standard lettering, the PEM-3020 2D/3D/4D is essential. Its 4D mode lets you offer portrait carving as a premium service, differentiating your business from workshops limited to flat lettering.
Manufacturers running multiple engraving jobs in parallel — lettering, borders and relief carving across a high daily volume of granite and marble pieces should look at the ACM-3015 2Q. Its dual-head design reduces cycle time across large production runs.
Toolpaths generated from vector designs or photographs are executed with consistent depth and detail across every piece, giving monument and tombstone lettering a uniform, professional finish.
The PEM-3020 supports flat lettering, raised or sunken relief carving, and photo-realistic 4D portrait engraving giving monument businesses the flexibility to offer multiple finishing styles from one machine.
The ACM-3015 2Q runs two engraving heads simultaneously, allowing parallel jobs on separate stone pieces and significantly reducing per-piece cycle time for high-volume monument production.
All machines in our stone engraving range are compatible with standard diamond and carbide engraving bits, giving you access to a wide range of tooling suppliers for different stone hardness levels and design detail requirements.
The control software supports a wide range of fonts and scripts, including regional Indian languages, enabling monument manufacturers to fulfil inscription requirements across different customer communities.
Every stone engraving machine is manufactured at our Rajasthan facility. Spare parts, technical support and on-site service are available without dependence on overseas suppliers, reducing downtime when your production line needs attention.
Every stone engraving machine in our range is engineered and built at our own facility. We control design, component quality, build tolerances and after-sales support there are no third-party trade margins between you and the machine.
Our four models are not catalogue fillers each addresses a distinct production need, from entry-level lettering to advanced 4D portrait carving and dual-head high-output engraving. You buy what fits your monument or stone business, not the nearest available option.
Designed around the power supply conditions, stone block and slab sizes, and operational environments typical of monument workshops and granite and marble processing units across Rajasthan, Gujarat, Andhra Pradesh and Tamil Nadu India's major stone processing regions.
