The one and only machine in the world to fabricate lines and spaces under 100µm (FP-21T Series)

Since high-frequency characteristics is necessary for RF circuit boards, it is important to mill sharp edged lines and spaces as below.

However, the lines and spaces milled by average prototyping machine with 60 degrees milling cutter (without run-out in consideration) will result to the picture below;  un-perpendicular cutting edge, which is inadequate for RF circuit boards.

Reason why FP-21 series are capable


0.05mm(50µm) For 21T Precision
0.15, 0.2, 0.3, 0.5mm
HF Milling bit

1. Holds necessary tools to fabricate

2. Low runout of the spindle motor 

FP-21T Precision Within 10µm
FP-21T Within 25µm

3. Capable of Stepping fabrication

Reason why competitor’s machines are incapable


1. They don’t own adequate tool bit

36mm, d=0.15mm (6mil)
36mm, d=0.25mm (10mil)
36mm, d=0.40mm (16mil)
End Mill (RF)

2.  Runout of the spindle motor is not specified

3.  Incapability of Stepping fabrication

 More features of FP-21T series

FP-21T / FP-21THP

Performs spacing of 0.1mm or more in milling precision.

  • With having 30mm in Z-axis stroke, it enables to process thick materials.
  • By using the optional vacuum table, it enables to process thin materials (200µm minimum).
  • The machine can process PCB larger than its working area (maximum 2000 mm), in Y-axis, using the software.
  • Compatible with various materials other than substrates, 2.5 Dimensional work and additional work.
  • Process methods, absolute and incremental, are easily changeable manually.
  • With FP-21THP (air floatation model), the material is processed without contact, leaving no markings or scratches: which is suitable for flexible materials such as Teflon.
FP-21T Precision

An Extreme precision machine which performs 50µm spacing. Optimal for microwave designs.
