Guide to selecting a Horizontal Boring & Milling Machine

KURAKI has as many Horizontal Boring & Milling Machine models to fit our customers' needs. Here are some points to assist in selecting the optimal machine for your requirement.

Points for selection

●Point1 Select by a spindle diameter

The main spindle of the KURAKI Horizontal Boring & Milling Machine is a feeding type with a spindle diameter 110 mm, 130 mm, or 150 mm. Normally, the larger the spindle diameter, the stronger the twisting rigidity becomes for heavy-duty cutting. For machining soft materials like aluminum, a high-speed quill spindle is recommended.

●Point2 Select by a workpiece weight and size

Confirm that the workpiece to be machined matches the machine table size (worktable size) and workpiece allowable mass. Select a bigger size than expected, not an exact size for the workpiece, so that the optimal machine performance can be performed.

●Point3 Select by an axis travel

Axis travels vary depending on the workpiece machining positions and the machining widths. The larger the W-axis (Quill travel), the deeper the machine can cut. The larger the X-axis and Y-axis values become, the wider and higher the workpiece can be.
