Desktop CNC Milling Machine SRM-20
Desktop CNC Milling Machine SRM-20
Includes full training and on-site installation
The SRM-20 is an affordable, compact, yet powerful desktop CNC milling machine, perfect for easily creating realistic parts and prototypes in an office, home, or classroom environment. For users with advanced CNC machining needs but lacking professional background, the SRM-20 is the simplest and most precise small CNC milling machine in its class. It is a new generation desktop CNC tool, equipped with a micro-stepping motor drive system, clear and precise forming technology, and twice the speed of previous generations.
.Precision and Productivity
The SRM-20 can precisely cut a variety of materials, such as wax, wood, foam, acrylic, polyacetate, ABS, and PC boards, allowing you to create realistic 3D prototypes. Common CNC application industries include product innovation, wax pattern casting, industrial equipment, automotive prototyping, gaming, and art production, offering flexibility to realize your creativity and designs.

.Multi-Axis Milling with X, Y, Z Axis Control
The SRM-20 features touch buttons and a VPanel controller for adjusting cutting speed and spindle speed on the X, Y, and Z axes, along with a new independent collet system for faster Z-axis origin setting and quick tool changes.

Product Features:
.Easy CNC Machining via VPanel
The SRM-20 is equipped with a VPanel controller that has a simple operating interface for adjusting tool position and setting the cutting start point. It can control feed rate and spindle speed through pause and resume functions, and supports millimeter and inch data tracking for X, Y, and Z axes.

.Efficient Independent Collet System for Tool Change
No need to change the spindle for different tool shank diameters; simply change the collet chuck for quick Z-axis positioning and tool changes.
.Smart, Safe, and Clean Design
The SRM-20 features a fully enclosed design, effectively reducing dust and noise. It has viewing windows on both sides and an intelligent safety interlock device. The machine automatically pauses when the cover is opened and resumes operation by selecting "continue" after closing the cover, preventing accidents. Internally, it incorporates several innovative technologies, such as an airtight structure to prevent debris from entering the spindle and Y-axis, eliminating interference from milling chips and ensuring stable long-term operation of the CNC equipment.

.Suitable for Educational Institutions
The SRM-20 is ideal for classroom use, supporting students in creating complex parts and testing models in design, technology, or industrial fields. CNC and 3D printers have become the ideal prototyping technology combination for STEAM educators.

.Stability and After-Sales Service
In addition to stable and reliable advanced technology, 3DMART offers a one-year manufacturer's warranty, complete with full training and on-site installation services.
