Horizontal Milling Overview

A horizontal CNC machining center or mill has a variable speed spindle that rotates cutting tools in a horizontal orientation. The raw material is clamped directly to the index table or with the aid of a fixture. The spindle assembly and live tooling move along the travel column in a vertical direction. The index table maneuvers the workpiece in a horizontal, front to back, and rotated position against the cutting tool to achieve the precise cutting path required for removing material. We offer vast selections of surface finishes from semi-finished to fine finishing of machine parts. Like CNC turning, this is a subtractive manufacturing process.

Horizontal CNC machines allow for multiple side machining of heavier parts, extended tool life, and have cleaner gravity chip removal compared to vertical milling centers.

CNC stands for “computer numerical controlled.” Our CNC machining service converts your CAD files into G-code using sophisticated CAD/CAM software. This machining language precisely controls our CNC machines using multi-axis coordinates. This information can also create samples using 3D printing technology.

Horizontal Mill Anatomy

Spindle Assembly - Variable speed spindle rotating in a horizontal orientation, which holds the cutting tool
Spindle Quill - Extendable section of the spindle machining difficult areas of the workpiece due to clearance, the W-axis
Multi-Point Cutting Tool - Removes material from the workpiece to form a part - subtractive manufacturing
Traveling Column - The column the spindle and tooling travel vertically upon in the Y-axis
Index Table Platform the workpiece clamps to which moves in the X-axis (perpendicular to the tool), Z-axis (parallel to the tool), and rotates on the B-axis
Fixture - A mechanical apparatus used to position and hold the workpiece to the index table
Workpiece - Clamps to the index table directly or with the use of a fixture

Horizontal machining centers equipped with a spindle quill are also called “Boring Bars” in the industry.
