The Level 3 Package is aimed at high-volume industrial manufacturers, regional storefront suppliers, and enterprise fabricators demanding ultimate multi-shift reliability.

For continuous, high-capacity commercial manufacturing, the Level 3 Package is engineered to maximize your operational velocity while drastically reducing labor costs per unit. By consolidating multiple manual layout and machining steps into a single, elite automated CNC machining Center, this setup completely eliminates production floor bottlenecks and drives unmatched profitability.

The Alcor II CNC Profile Machining Center

The Alcor II is the ultimate automated powerhouse for high-volume commercial storefront fabrication. By consolidating high-speed drilling, routing, rigid tapping, and complex milling into a single automated cycle, it completely eliminates manual layout errors and shop floor bottlenecks.

Multi-Side Processing: Automatically machines multiple faces of aluminum profiles in a single setup, ensuring perfect hardware and drainage alignment without manual flipping.

7 units of fan cooled spindle motors that can function and be positioned as different angles enables an unlimited operational capability on 4 surfaces of the profile.

Maximum Labor Efficiency: Operators simply load the profile and hit start, the programmable CNC system handles the rest with millimeter accuracy.

Industrial Rigidity: Built on a heavy-gauge steel monolithic base to absorb extreme cutting forces, guaranteeing flawless, burr-free architectural finishes during demanding multi-shift operations.

The Alcor II C replaces a four-step manual fabrication process with an elite, one-pass automated ecosystem, allowing you to massively scale daily volume while slashing labor costs.

End Milling Machine

The Polar IV End Milling Machine is indispensable for machining storefront glazing legs, which must be precisely notched. Instead of slow, inaccurate manual back-cutting, the Polar IV clean-mills the glazing leg at a perfect 90° angle. With its quick-change cutter stacks, operators can instantly switch between different storefront profile depths without costly downtime, dramatically speeding up frame assembly while ensuring structural integrity.

Why the Level 3 Line Pairs the Polar IV with the Alcor II CNC

A common question from high-volume manufacturers is: “If the Alcor II is an elite, multi-axis CNC powerhouse, why do I still need a dedicated Polar IV End Milling Machine?” The answer comes down to two critical industrial principles: maximizing CNC cycle efficiency and parallel processing.

  • Protecting Your Highest-Value Asset: The Alcor II is designed for complex, multi-sided geometry along the length of the profile (locksets, panic bars, and intricate hardware preps). If you force your primary CNC center to stop and perform heavy end-notching on transoms and mullions, you create an expensive operational bottleneck.
  • Parallel Processing for 100+ Units Daily: To maintain true industrial velocity, your cutting, routing, and jointing stations must run simultaneously. While the Alcor II is executing multi-side programming on vertical jambs, the Polar IV can be utilized to instantly prep interlocking horizontal joints.
  • Zero-Downtime Batching: The Polar IV uses physical, pre-configured quick-change cutter stacks. Operators swap the blade stack in seconds to match the exact step-profile of the new glazing leg.

The Bottom Line: We don’t include the Polar IV because the Alcor II can’t do the job, we include it because splitting the workflow keeps your CNC free to do what it does best. This smart separation of labor is exactly how a Level 3 shop achieves maximum daily profitability and continuous throughput.

  • Dedicated Storefront & Architectural Expertise

    The Reality: Generic machinery forces your operators to constantly fight tool deflection, poor finishes, and slow cycle times on heavy commercial shapes.

    Our Approach: We don’t sell "one-size-fits-all" machinery. Every upcut saw, end mill, and CNC center in our catalog is specifically selected, geared, and rigidly engineered to process heavy-walled architectural aluminum and complex storefront extrusions. We speak your language from shear blocks and glazing legs to deep pocket profiles.

  • Fully Synchronized, Turnkey Systems

    The Reality: Buying a saw from one vendor, a copy router from another, and die sets from a third creates an integration nightmare, causing weeks of costly production delays.

    Our Approach: We engineer complete, unified production ecosystems. From the precise tooth count on your Meteor 420 blade to the custom-machined pneumatic dies in your Air Press, our components are designed to work together flawlessly. Your profiles flow seamlessly from cutting to milling, punching, and final assembly.

  • Comprehensive, Local USA Based Support

    The Reality: Unreliable machinery or a lack of technical guidance can stall an entire contract, risking your reputation with general contractors.

    Our Approach: Our relationship truly begins after the sale. We provide the comprehensive technical expertise, custom shop-floor layout guidance, and ongoing service support required to maximize your throughput and keep your operational downtime to a minimum. If your line isn't running, you aren't earning and we make it our mission to keep you moving.
