Spindles
PCB Drilling and Routing
Spindles with Vast Speed Ranges for Increased Productivity
Unparalleled Performance
PCB drilling and routing require extreme rotational speeds, minimal runout, and uncompromising reliability. Westwind air bearing spindles are engineered specifically for high-volume PCB manufacturing environments where precision and uptime directly influence yield and profitability.
With ultra-low radial error motion and exceptional thermal stability at very high RPM, these spindles produce clean micro-vias, precise hole geometry, and superior routing edge quality. Reduced tool wear and consistent dimensional accuracy allow manufacturers to increase throughput without sacrificing quality.
In PCB production, precision is profit — and air bearing spindle technology ensures both.
Designed for Continuous Operation
Modern PCB manufacturing operates continuously, often around the clock. Spindles must maintain dimensional stability over long duty cycles without thermal drift or bearing degradation.
Because air bearings eliminate mechanical contact, there is no bearing wear, no lubrication contamination, and minimal heat generation. This translates into predictable long-term performance, extended service life, and reduced total cost of ownership.

Built for the Next Generation of Electronics
As PCB densities increase and drill diameters shrink, tolerances tighten. Westwind PCB drilling spindles are engineered to meet these evolving requirements with high-speed capability, low vibration characteristics, exceptional stiffness, and compact integration options.
Where others focus solely on speed, Westwind engineers complete spindle performance — balancing speed, stability, and reliability to support next-generation electronics manufacturing.
