As a small milling machine, the SRM-20 offers a 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 classrom environment.
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.
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.
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, and Z axes, and a new independent collet system that allows for faster setting of the Z-axis base point and quick tool changes.
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 SRM-20’s VPanel controller provides a simple interface for adjusting tool position and moving the cursor to set the milling starting point.
It’s no longer necessary to change spindles every time there’s a different end mill shank diameter.
The SRM-20 has a fully-enclosed cabinet that reduces dust and noise and features a side-window for easy progress viewing.
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 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.
In addition to highly reliable technology and unmatched customer support, Roland DGA offers a one-year manufacturer’s warranty on the SRM-20.
