4MILL300 - COMPACT PCB PROTOTYPING
PCB up to 200 × 140 mm · 1 µm resolution · 60,000 RPM · Tool-free Push & Turn tool change
Product detailed description
Bring professional PCB prototyping directly into your laboratory.
The 4MILL300 is a compact bench-top PCB milling machine designed for schools, universities, electronics laboratories and engineering teams that need to manufacture PCB prototypes directly in-house.
It supports milling and drilling of single-sided and double-sided PCBs, precise isolation routing, PCB outline cutting and other light machining operations without requiring chemical etching.
Built for Fast In-House PCB Prototyping
The 4MILL300 combines precision mechanics with a high-speed 60,000 RPM spindle to produce prototype PCB structures directly from prepared manufacturing data.
Tool changes are quick and straightforward. The 4MILL300 uses a convenient Push & Turn tool-change system, operated directly from the top of the spindle. Milling and drilling tools can be released and secured by hand, without wrenches or additional tools.
The machine can drill holes from 0.2 mm and mill isolation paths down to 0.1 mm, making it suitable for standard THT boards, SMD prototypes, antennas and a wide range of engineering applications.
No Chemical Etching Required
PCB patterns are created mechanically by precision milling. This provides a clean laboratory workflow without the chemical handling associated with traditional prototype etching processes.
What Can You Produce With the 4MILL300?
Integrated Dust Extraction System
Milling and drilling PCB materials generates fine machining particles that should be removed directly from the working area.
The 4MILL300 features an integrated dust extraction system designed to remove particles directly from the machining area. For operation, the system is connected to an external dust extraction unit.
For a fully integrated setup, the machine can be combined with the MIPEC DEU-400 Dust Extraction Unit , developed specifically for MIPEC 4MILL PCB milling machines.
Automatic Extraction with DEU-400
When connected to the MIPEC DEU-400, dust extraction can operate automatically together with the milling spindle. The extraction unit starts when machining begins and switches off when the spindle stops, eliminating the need for separate manual control.
From PCB Data to a Physical Prototype
The 4MILL300 forms the physical machining stage of the MIPEC PCB prototyping workflow. Once project data has been prepared, the machine performs isolation milling, precision drilling and PCB outline routing.
