Create Realistic Prototypes

A wide range of materials, including modeling wax, chemical wood, foam, acrylic, poly acetate, ABS and PC board can be precision milled using the SRM-20 small milling machine, allowing you to create realistic 3D prototypes that are virtually identical to production parts.

Precision and Productivity

Engineered for optimum efficiency and productivity, the SRM-20 is a next-generation desktop mill that boasts a micro-step motor drive system for clean and precise contours and a phenomenal feed rate that’s two times faster than previous generations.

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.

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.

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”.

Other Distinguishing Features

  • Subtractive prototyping of complex snap-fits
  • Maximum Axes Operation: 8″(x) x 6″(y) x 2.38″(z)
  • Bundled software suite including SRP Player
  • Powerful spindle motor
  • Independent collet system
  • G-Code Compatible

Included Software for Experts and Beginners

SRP Player CAMsrp player

From design to mill in three simple steps. Roland’s MDX rapid prototyping machines come complete with SRP Player Software to prepare your CAD model for RP manufacturing with no programming skills required.

Step 1 – Design
Design your 3D CAD model and export it as an .STL, .DXF, .3DM, or .IGS/.IGES file.
Step 2 – Import
Open the file in Roland SRP Player software and simply use the five-step wizard to process the data for your Roland MDX rapid prototyping machine. You don’t have to worry about feeds and speeds, cut depth, surface selection or G-Code programming: SRP Player does it all for you!
Step 3 – Mill
SRP Player automatically generates machine tool paths and a finished preview. Just click Send to Machine to mill a prototype with smooth surfaces and tight tolerances from your choice of material.

ClickMillroland clickmill

ClickMill Software provides direct control of the for surfacing, drilling holes, cutting pockets and other finishing processes, all without having to access CAD or CAM software.

G Code Supportroland cnc g-code support

Each CNC Mill supports the G-code NC programming language, making it well suited for both professional and educational applications.

Virtual Control Panel (VPanel)mdx-50

VPanel serves as a computer-based virtual control panel with all of the functionality of the physical on-board control panel, as well as tool life management and e-mail alerts.
