Kellyder Custom CNC Milling Service

Kellyder’s Custom CNC Milling Service stands at the forefront of modern machining, harnessing the power of advanced CNC technology to shape metal with unmatched precision.

Our state-of-the-art milling machines, constituting nearly 80% of all new machining equipment, skillfully rotate cutters and move them along multiple axes to intricately work the material.

Our expertise is not just limited to creating flat and square surfaces; our team of skilled machinists can intricately cut angles, form radii, bore holes, and execute complex geometric patterns.

Utilizing special cutters, we can intricately craft gear teeth, dovetails, and tee slots, and our advanced equipment allows for the creation of circles, helical shapes, and even custom form shapes.

At Kellyder, we’re committed to delivering customized milling solutions that meet the diverse and complex needs of our clients, ensuring precision, efficiency, and quality in every task
