Micromilling

NS CNC for Research and Development Laboratories

NS CNC has been producing various mini CNC machines for research and development laboratories and universities for many years. We build very high-precision machines but with a very budget price. Our machines work in many branches of natural science, with various types of milling, turning, drilling, laser processing, etc.

Milling a Microfluidic Devices

Our NS CNC machines are very widely used for making microfluidic chips. Channel milling, measured in micrometers, requires a very high accuracy of movement of the machine carriages, the strength of the machine base, the absence of spindle runout and its enormous speed.

On this page, we feature some of the notable published work of Professor Andre Simpson’s Research Group from the University of Toronto. Their laboratory has been using several high-precision NS CNC milling machines 4-, 5-axis with spindles and laser for many years.

Unfortunately, we do not have the opportunity to share the work of other scientific laboratories using our machines.

Professor Andre Simpson examines the first milled copper spiral coils on the Mira 6. September 2017

A 16-turn spiral coil with a 1.5 mm outer diameter was milled from Copper-coated Teflon. Both the turns/wires and the spacing between them are 0.02 mm wide.

A 3-turn microcoil with a 1 mm inner diameter was milled from Copper-coated Teflon. Both the turns/wires and the spacing between them are 50 µm wide

Shown is a Slotted Tube Resonator milled from a copper pipe with an 1.270 mm outer diameter and an 0.813 mm inner diameter. Each strip is 7 mm long and is spaced 0.8 mm apart. The slotted tube resonator was soldered onto a specially designed circuit board that was milled from Copper-coated Teflon

Two 1 mm X 9 mm microstrips (with a built-in 2mm wide, 7mm long, and 1.58mm deep sample chamber behind the microstrip) are shown.

Parts of two 1 mm X 5 mm double-sided microstrips were milled from an FR1 PCB Board and soldered together. Acrylic inserts containing microfluidic channels (that will contain the sample) were milled from an acrylic rod and used to introduce the sample between each strip. One is designed to keep larger mass-limited samples between the two microstrips (top) while the other contains only microfluidic channels and is intended for liquid samples (bottom). All components were machined on a Mira-6

The Solenoid was made from a 6.4mm Diameter Copper coated Acrylic Rod, made on Mira 6.

The front of a 3 mm long and 0.15 mm wide microstrip (made from copper-coated Teflon) is shown. The microstrip contains a built-in 1mm wide, 3mm long, and 1.58 mm deep sample chamber on the opposing side (shown in next photo)

Proffesor Ronnie Willaert from the Vrije Universiteit Brussel, Belgium

Professor Ronnie Willaert (Vrije Universiteit Brussel, Brussels, Belgium) has extended expertise in yeast research (Saccharomyces cerevisiae, Candida albicans, and C. glabrata) and single-molecule biophysics.

He has considerable experience in optical nanomotion detection as well as in biofabrication (including microfluidic chip and micropattern development). He focuses on developing and using micro- nanobiotechnological techniques to study bone and yeast cells in microgravity (International Space Station) via European Space Agency (ESA) and Belgian Science Policy Office (Belspo) sponsored research project.

Currently, he is using the CNC Elara (NS CNC) as a fast-prototyping method to optimize a microfluidic chip that will be used for the ESA project “FLUMIAS Yeast Nanomotion”, where yeast cellular nanomotion will be used to assess the effect of antifungals on the viability of yeast cells in space conditions (ISS).
