Horizontal Boring

Horizontal boring is the ideal solution for large-scale machining with high productivity and application flexibility. The available range of applications allows the development of dedicated solutions with maximum machining productivity, such as turnkey processes for wind turbine components, hydroelectric power plant components and large components in the aerospace sector.

Providing Large Part Horizontal Boring Services to American Manufacturing Companies

Elimold is an industry-leading provider of large part machining services. We are committed to providing unparalleled customer service, ensuring the highest part quality, and achieving exceptional precision in the machining process. Our superior horizontal drilling capabilities ensure timely, accurate, and high-quality part production for every order.
Our horizontal boring mills are used to produce parts for a wide variety of industries. Our boring mills are often used for precision metal cutting of heavy industrial parts. Since many of our customers’ machines require large metal parts with identical holes, the boring mills we use cut precise holes with extreme accuracy and efficiency. We can easily enlarge holes that have already been drilled or cast.
We are known for our expertise in machining large parts on large horizontal boring mills. We use small bridge ports to horizontally machine and bore small manufacturing equipment components. Our machinists are experts in performing horizontal milling operations using spindle boring mills.

Horizontal Boring Capabilities

Elimold Corporation provides horizontal machining services for prototypes and short-run production of a variety of large components. With extensive production capabilities, including 3-axis machining and CNC controls, we can machine components weighing up to 70 tons. These components are manufactured to very tight tolerances, including +/- 0.0005 inches for milling and +/- 0.0002 inches for drilling operations.
We perform boring, drilling, milling, tapping, and reaming operations. CAD/CAM programming is created from drawings provided by the customer in the appropriate format. We accept drawings and designs in different file formats, including DWG, DXF, and IGES. Our machining capabilities allow us to custom machine large metal components based on customer printed specifications.

What is CNC Horizontal Boring?

Horizontal boring is a drilling process that allows for more accurate holes. Horizontal boring is primarily used to drill holes in larger parts and components or to further enlarge existing holes in a workpiece to improve their dimensional accuracy.
However, horizontal drilling can also be used on workpieces of various shapes and sizes. To produce high-volume applications faster, we specialize in CNC horizontal drilling. We utilize advanced horizontal drilling centers and computer numerical control units to fully automate the control, movement and accuracy of our horizontal drilling methods.


From standard metals to high-performance alloys and engineering plastics, our skills and equipment allow us to work with an expansive portfolio of materials, such as:

  • Steel
  • Stainless steel
  • Aluminum
  • Brass
  • Copper
  • Bronze
  • Nickel
  • Cast iron
  • Inconel
  • Hastelloy
  • Plastics

Key Differences Between Horizontal and Vertical Drilling

The main difference between horizontal and vertical boring is that the workpiece is stationary in a horizontal milling center. Whereas, the tool in a vertical milling machine is stationary and the workpiece is moving. Between the two, CNC horizontal boring mills offer more flexibility in tool capabilities and can also be equipped with special tools or options.
With horizontal drilling, operators have more freedom in approach and machining process. It also ensures efficient machining, especially for projects that require a lot of chip removal.
