Horizontal Machining Centers (HMCs)

A horizontal machining center (HMC) is a machining center with its spindle in a horizontal orientation. This machining center design favors uninterrupted production work. One reason for this is that the horizontal orientation encourages chips to fall away, so they don’t have to be cleared from the table. More significantly, the horizontal design allows a two-pallet workchanger to be incorporated into a space-efficient machine. To save time, work can be loaded on one pallet of an horizontal machining center while machining occurs on the other pallet.

The Costs and Benefits of Horizontal Machining


The shift from vertical to horizontal machining was even more expensive than this shop anticipated. It was also more valuable. Most of the shop’s machining centers are HMCs now—here’s why.

Adopting a 24/7 Mindset


This shop considered a number of factors before establishing an effective process to run an HMC cell around the clock for applications in aerospace, oilfield and other industries.

A Production Line Takes Shape


Although Pointe Precision built its reputation on low-volume, high-complexity aerospace and medical parts, its expansive high-volume production line may be its biggest success to date. Sound decision-making and attention to details at every step are the keys to this success.

Vertical Machining Cells Challenge Horizontal Dominance

By: Matt Danford
When part volumes are high, and success is measured in pennies and seconds, moving away from horizontal machines requires creative thinking about robotics, cutting tools, workholding and more.

Four Companies Partner to Deliver Optimized Tooling Solution
