Description
Take your PF 230 or FF 230 from manual to precise. The Proxxon Fine Feed (No. 24140) is a drop-in upgrade that replaces the standard height feed with a micrometer-style fine feed mechanism — giving you repeatable, measurable depth control that's essential for accurate milling, facing, and step cutting. One full revolution moves the spindle exactly 1/16" (1.5mm), with each graduation representing 0.002" (0.05mm). The scale resets to zero for easy incremental referencing.
Key Specifications
- Compatible machines: Proxxon PF 230 Milling Machine, FF 230 Micro Miller
- Feed per revolution: 1/16" (1.5mm)
- Graduation: 0.002" (0.05mm) per division

- Weight: 345g
- Part No.: 24140
Why Upgrade to Fine Feed?
The standard height feed on the PF 230 and FF 230 is adequate for rough positioning, but lacks the resolution needed for precise depth-of-cut control. The fine feed upgrade gives you:
- Repeatable depth settings you can dial in and return to
- Controlled incremental cuts without guesswork
- A resettable zero reference for multi-pass operations
- Tilted-position fine feed for angled milling work
Frequently Asked Questions
Is this compatible with both the PF 230 and FF 230?
Yes — the No. 24140 fine feed is designed for both the Proxxon PF 230 Milling Machine and the FF 230 Micro Miller.
How difficult is installation?
Installation is straightforward and requires no machining or modification. The unit is designed to fit directly onto the existing spindle feed mechanism.
What's the finest increment I can set?
Each graduation on the scale represents 0.002" (0.05mm) — sufficient for precision facing, step milling, and controlled depth-of-cut work on the PF 230 and FF 230.
Works Well With
- Proxxon Compound Table KT 230 (No. 24106) — adds X/Y axis travel to complement the fine feed's Z-axis control
- Proxxon 4-Piece HSS Milling Cutter Set (No. 24610) — end mills for precision milling operations
- Proxxon 4-Piece HSS Milling Cutter Set 6–10mm (No. 24620) — larger diameter end mills for heavier cuts
