Product Description

monoFab™ SRM-20

Compact Milling Machine


Desktop Milling Machine

As a small milling machine, the SRM-20 offers compact size and powerful functionality at an affordable price. Production of realistic parts and prototypes is made simple and convenient with a device that fits into any office, home, or classroom environment. For users looking for advanced milling capabilities without the need for expert operating skills, the SRM-20 is the easiest and most precise CNC mill in its class.


The Power of SRM-20 in Education

 The SRM-20 is perfect for any classroom and offers students the chance to experience cutting-edge technology in preparation for careers in the design, technology and engineering industries. The SRM-20 empowers students to engineer and output intricate proof-of-concepts, parts and scale models, and has become an invaluable yet affordable option for STEM and STEAM educators to put advanced prototyping technology in their classrooms.

Create Realistic Prototypes



Multi-axis milling is as easy as X, Y and Z
The SRM-20 was designed with a number of technological advancements that include a touch-button VPanel controller to regulate feed rate, spindle speed and milling on a complete X, Y, Z axes, and a new independent collet system that allows for faster setting of the Z-axis base point and quick tool changes.


Software Included for Out-of-the-Box Productivity

Available for download from Roland OnSupport, the following software offers user-friendly operation for all aspects of  milling on the SRM-20:

SRP Player
A user-friendly CAM software with advanced editing capabilities that lets users explore new milling capabilities as their skills progress. Supports popular CAD file formats like STL, DXF, Rhino 3D Model and IGES. Learn more

MODELA Player 4
Easy-to-use CAM software that processes STL files produced by popular CAD programs. Features include uniform 3D scaling, selection of milling direction, automatic tool path generation, and control of cutting depths and speeds from a predefined library or user-defined setting. Learn more

iModela Creator
Use drawing tools to sketch out ideas before milling shapes, holes, textures and patterns. Then simply load your cutting material into the mill, and the SRM-20 does the rest, recreating your design in precise detail.

Virtual MODELA
A powerful software tool that eliminates milling errors, simulates finished shapes and estimates production time.

Software to directly control surfacing, drilling holes, cutting pockets and other finishing processes on the SRM-20, all without accessing CAD or CAM software.

Convert any standard TrueType or Outline font into a ‘Stroke Font’ or single line font for engraving.

Independent Collet System for Efficient Milling
It’s no longer necessary to change spindles every time there’s a different end mill shank diameter. Now you can replace the collet chuck in order to match the shank diameter for fast setting of the Z-axis base point and for quick tool changes.

Smart Yet Rugged
The SRM-20 includes the very latest CNC milling features such as airtight sealing technology to prevent waste material from getting inside the spindle and Y-axis, making it resistant to the effects of milling debris and adding durability for long-term operation.

The Clean Machine
The SRM-20 has a fully-enclosed cabinet that reduces dust and noise and features a side-window for easy progress viewing. It also features an intelligent safety interlock to that automatically pauses the machine when the cover is opened, permitting milling to resume upon closing the cover and selecting “continue”.
