Horizontal Mills

Horizontal mills can perform a number of applications in one setup, and their configuration allows for machining large parts. The arrangement of the horizontal boring mill allows for easy access and placement of the workpiece on the machine table. Large workpieces can be placed on the machine table with an overhead crane and can overhang the table if needed. The arrangement also allows for easy chip removal from the machining operation.

Large Part Horizontal Milling

We run five horizontal mills out of our shop. The largest has an operating window of 157″ in X and 92″ in Y. An auxiliary rotary table can be added to the mill for 4th axis milling while a part is being rotated. This adaptation is used for machining parts such as fluted rolls and internal helical grooves inside bushings. Two of our horizontal mills have rotary tables for machining on different sides of the part in one setup.

I have had the privilege of working with Withers Tool for the last 15 years on various projects. The projects have ranged in size from small to very large and they have always proven themselves time and time again. Competitive pricing and great service can always be expected.

Professionalism at it's Best

Great experience. Withers goes above and beyond to ensure they exceed your expectations.
- James Bradshaw


Withers understood the importance of my position with a press down and meeting customer's expectations. Withers had no warning as to the scope of the work. They worked late and came in very early to ensure that I had the equipment back in 24 hours. There is no other shop in Atlanta with the resources that would make a commitment as what Withers did.
