Double Head Cutting Machine In aluminum and PVC/vinyl window, door, and curtain wall fabrication, every frame member starts the same way: a length of extrusion that needs to be cut to exact dimensions, at precise angles, before it can become part of a finished unit. Get those cuts right — clean, square, and consistent — and the rest of fabrication flows. Get them wrong, and you're carrying errors through every downstream operation: poor corner joints, gaps at assembly, and re

In aluminum and PVC/vinyl window, door, and curtain wall fabrication, hardware doesn't just get screwed onto the profile — it gets seated into it. Locks, handles, hinges, latches, and opening channels all require precisely milled slots cut into the profile face before the hardware can be mounted. Cut those slots inconsistently, even by a fraction of an inch, and you get hardware that binds, rattles, or won't seat flush at all. Done with a hand router, this operation depends e

In this post, I’ll share my insights on how Oz Machine USA compares to other options on the market. Let’s dive into the details and se

In aluminum and PVC/vinyl window, door, and curtain wall fabrication, one of the most critical operations is the end milling of mullion and transom profiles. Before a mullion can fit into a frame, its end must be precisely milled. This creates a tight, flush T-joint that holds structurally and seals reliably. Doing this manually is slow and inconsistent. Using the wrong machine can lead to loose joints, visible gaps, and costly rework. The POLAR-IV and POLAR-V from Oz Machine
