CNC Conical Burr Electric Grinder
01 · Architectural Overview & Extraction Engineering
5-Axis CNC 420 Stainless 38mm Conical Burrs • 38 Stepped Micro-Grind Settings • Low-RPM Anti-Static Magnetic Catch Cup. Engineered by Vespera Bar for quiet countertop authority, zero-retention workflow, and repeatable thermal and gravimetric precision.
5-Axis CNC 38mm 7-Core Conical Burrs
Machined from nitrogen-hardened 420 stainless steel to 58 HRC hardness, slicing beans cleanly with minimal fines for sweet, high-clarity espresso and pour-over.
38 Stepped Micro-Adjustment Clicks
External stepped ring transitions smoothly from Turkish and 20-bar/58mm espresso (Clicks 1–10) to V60 pour-over (Clicks 18–26) and cold immersion (Clicks 30–38).
Low-RPM Cold-Grind Planetary Drive
High-torque reduction gearing grinds at low RPM to prevent frictional heat buildup, preserving volatile floral and cacao aromatics.
Zero-Retention Magnetic Catch Cup & Walnut Cap
Neodymium magnetic dosing cup detaches with a twist and pairs with a solid American walnut single-dose hopper lid.
