Why We Use Citizen R04 for Semiconductor Micro Precision Machining?
Aug 28, 2025
Citizen R04 Swiss-Type CNC Lathe for Ultra-Fine Manufacturing
A high-precision Swiss-style CNC lathe made especially for producing ultra-fine components is the Citizen R04. It is extensively used in the optical, medical, semiconductor, and watchmaking sectors, where long-term production stability and micron-level tolerances are crucial.
At Manners Technology, we use the Citizen R04 to manufacture our entire line of endoscope tubes, stainless steel laser-cut hypotubes, and other CNC machining parts. The R04 is the ideal choice for producing semiconductor-grade hypotubes due to its high spindle speed, nano-level interpolation control, and automatic stability.
Key Features of Citizen R04
Micro-diameter machining: Ideal for components from φ0.1 mm to φ4 mm.
Ultra-high spindle speed: Reaching up to 20,000 rpm for extremely fine cutting.
Rigid tool arrangement: Guarantees stability when machining miniature parts.
Automation ready: Compatible with bar feeders for long-duration unmanned operation.
Nano-level precision: Thermal compensation and nano interpolation ensure ±1 μm accuracy.
This is why the R04 is recognized as the "micro-precision expert", especially for semiconductor hypotube production.
Precision Needs of the Semiconductor Industry
Why Semiconductor Components Demand Accuracy
The semiconductor industry requires uncompromising precision and surface quality. Every component-whether a probe pin, alignment sleeve, or micro shaft-affects wafer processing reliability. Typical demands include:
Micro connectors – Probe card contact pins with ±2 μm dimensional accuracy and Ra < 0.2 μm.
Precision sleeves and guides – For wafer handling alignment, requiring <3 μm coaxiality with high wear resistance.
Micro shafts – Found in lithography and wafer transport systems, often < φ0.5 mm with high length-to-diameter ratios.
Difficult-to-machine alloys – Tungsten, molybdenum, and stainless steel 316L, requiring stable machining and long tool life.
These requirements make Citizen R04 machining technology essential for producing hypotubes with the precision and reliability semiconductor manufacturers demand.
Application Cases of Citizen R04 in Semiconductor Hypotube Production
Case 1: Probe Pin Hypotube
Workpiece: φ0.25 mm × 6 mm, tungsten alloy.
Challenge: Long and thin structure, prone to bending.
R04 Solution: Swiss-type guide bushing supports the workpiece close to the cutting point; ultra-high spindle speed ensures clean tip formation.
Result: Accuracy ±1.5 μm, yield rate 99.8%.
Case 2: Wafer Handling Alignment Pin
Workpiece: φ1.2 mm × 15 mm, SUS304.
Challenge: High coaxiality and surface finish requirements.
R04 Solution: Precision guide bush eliminates deflection; secondary fine turning + super-finishing achieves mirror-level surfaces.
Result: Coaxiality <2 μm, Ra = 0.15 μm, fully meeting semiconductor standards.
