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.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible machines:\u003c\/strong\u003e Proxxon PF 230 Milling Machine, FF 230 Micro Miller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeed per revolution:\u003c\/strong\u003e 1\/16\" (1.5mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation:\u003c\/strong\u003e 0.002\" (0.05mm) per division\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScale:\u003c\/strong\u003e Resettable to zero\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeed modes:\u003c\/strong\u003e Vertical (height feed) and tilted position (fine feed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Easily installed — no machining required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 345g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart No.:\u003c\/strong\u003e 24140\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Upgrade to Fine Feed?\u003c\/h2\u003e\n\u003cp\u003eThe 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.
