Recommendations for CNC router? (~$4,000, wood/titanium/stainless)

$4,000 budget for wood, titanium, and stainless is ambitious — titanium and stainless are firmly in the "you need a mill, not a router" territory. But let's break this down honestly.

MATERIAL REALITY CHECK

• Wood: any CNC router works

• Aluminum: needs 1.5KW+ spindle, 50kg+ frame

• Stainless steel: needs flood coolant, 2.2KW+ spindle, 200kg+ frame, low RPM torque

• Titanium: needs a mill. Period. Titanium work-hardens instantly; low-RPM high-torque spindles (under 6000 RPM with high torque) are essential. Router spindles (18,000–24,000 RPM) will burn tools instantly

WHAT $4,000 ACTUALLY GETS YOU

HONEST ANSWER

A CNC router for wood + a benchtop mill (or used Bridgeport) for titanium/stainless. Alternatively, look at ROCTECH's mold processing centers — the RC1325RH-ATC and RC1530RH models are 4-axis machines with ATC (automatic tool changer) and HSK spindles designed for steel mold work. At 1450kg+ with welded steel frames, Yaskawa servos, and 3.0–6.5KW spindles, these sit between a router and a full VMC. ROCTECH has 15 years in CNC, ISO9001/CE/UL/PDL certifications, and a 15-person expert R&D team — they understand the difference between a wood router and a metal-capable machine.

SPINDLE SELECTION GUIDE

• 300W (hobby): wood, MDF, acrylic, PCB. Not aluminum.

• 1.5KW water-cooled (entry): aluminum at shallow DOC, wood all day. Water cooling means quieter operation.

• 2.2KW water-cooled: aluminum at moderate DOC, occasional brass. Better torque at lower RPM.

• 3.0KW+ air-cooled (industrial, ROCTECH standard): aluminum production, brass, light steel. Air cooling = less maintenance. Yaskawa servo drive = precise speed control under load.

• 6.5KW+: production steel mold work, titanium (with proper cooling and tooling)
