What We Deliver

Comprehensive precision manufacturing under one roof — from raw stock to finished assemblies.

01

Precision Milling

3, 4, and 5-axis CNC milling for complex geometries. Tolerances down to .0002", intricate features, and consistent repeatability across every run.

02

CNC Turning

Precision lathe operations for cylindrical components. Single-piece prototypes to high-volume production with the same exacting standards.

03

Sheet Metal

Precision sheet metal fabrication and forming. Clean edges, tight bends, and production-ready finishes for enclosures, brackets, and panels.

04

Mechanical Assembly

We integrate machined components into finished assemblies. Fewer vendors, less logistics, faster delivery from a single trusted source.

About CK Tool

More Value.
Every Part.
Every Time.

Founded in 1969, CK Tool is a precision machine shop with over 55 years of manufacturing experience. We operate 11 CNC machines with 8 skilled employees in our own 5,300 sq ft facility in Mountain View, CA — owner-occupied for long-term stability.

We love working with local companies — it allows us to interact closely with your engineering team for value-added feedback on saving costs. We also work with companies outside the area and ship product nationwide.

Lean

No waste. No bloat. Every process optimized for speed and cost.

Efficient

Robotic automation and smart scheduling maximize throughput.

Smart

Engineering-driven feedback that saves you money before cutting starts.

Simple

One point of contact. Clear communication. No runaround.
