When selecting a 3-axis vertical machining center for SMEs, the core principle is to first define machining requirements, then lock in key parameters like precision, rigidity, and efficiency. Balance budget with long-term costs, prioritizing models that are easy to maintain and backed by reliable service. Below are actionable selection steps and key considerations:
I. Define Core Machining Requirements (Selection Starting Point)
Workpiece and Material
Dimensions and Weight: Select travel based on the largest workpiece outline (X/Y/Z-axis travel should exceed the workpiece by 10%-20% to allow for clamping space). Ensure the worktable load capacity matches the workpiece weight. For example, when machining a 400×300mm plate, selecting X≥500mm, Y≥400mm, and Z≥450mm travel provides greater stability.
Material Properties: Machining steel/cast iron requires high rigidity (prioritize hard rails) and spindle power ≥11kW; aluminum/plastic parts may opt for high-speed spindles (8000–15000 rpm) and linear guide models for enhanced efficiency.
Accuracy Requirements
General parts: Repeatability ±0.005mm and positioning accuracy ±0.01mm suffice; precision molds/electronic components require ±0.003–±0.005mm, prioritizing semi-closed or fully closed-loop systems.
Production Mode
Small-batch, high-variety production: Select models with user-friendly operation, tool magazine capacity of 16–24 tools (supporting multi-process operations), and tool change time ≤2 seconds to ensure flexibility.
Mass production: Prioritize high rigidity, rapid traverse speed ≥36m/min, and compatibility with automated loading/unloading systems to enhance efficiency and equipment utilization.
