Colonial Tool Manufacture, repairs, and rebuilds all types of Motorizes Machine Spindles

Our motto, “Rigidity At Speed,” is also a necessary characteristic in all spindle applications. Coupled with a compact, high-horsepower integral motor, automatic tool actuator and compensator, it makes for state-of-the-art spindle technology that packs a big punch in a relatively small package. Motorized spindles require less space, since they have a direct-drive built in.

From the slim shape of a simple surface grinding spindle to the robustness and complexity of a cylinder boring spindle, Colonial has designed and built a full spectrum of motorized spindles. Our expertise has led us to become a leading machine spindle manufacturer, no matter how common the job or how many CNC specialty spindles you may need.

The benefits of milling spindle motors and others from Colonial Tool include:

• Increased productivity and product quality
• High-volume support for long use of tools
• Smart, long-term ROI thanks to quality designs
• Simplified maintenance and access
• Longer spindle service life and tool service life
• Spindles specifically designed to minimize machine downtime
• CNC specialty spindles engineered to meet a variety of needs

Our designs, repairs, rebuilds and other spindle motor work are all verified, tested and measured to insure that our development process meets a high standard and improves as we continue to operate.
