monoFab SRM-20

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.

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.
 

 

Produce More Prototypes with More Materials

The SRM-20 portable milling machine can mill a broad range of materials, including modeling wax, chemical wood, foam, acrylic, poly acetate, ABS and PC board. The following items are just some of the prototypes and applications made possible:

Product inventions
Wax molds for casting
Tools and machinery
Relief plaques and graphics

Vehicle prototypes
Game and model parts

Milling Made Easy with a User-Friendly VPanel

The SRM-20’s VPanel controller provides a simple interface for adjusting tool position and moving the cursor to set the milling starting point. The VPanel also allows easy control of feed rate and spindle speed with pause and resume operation, plus tracking of X,Y,Z axis milling with a numeric readout in millimeters or inches.



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”.

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 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.
