Aluminum Window Machine Double Head Cutting Saw LJZ2-450*3700A With Price USD 3300-3900
Eworld’s LJZ2-450*3700A double head aluminium window cutting machine retails at USD 3300–3900, built for precise aluminum door, window and curtain wall profile cutting. The main spindle is manufactured by the specialized manufacturer. And the imported linear bearing motional pair is used to move the head horizontally. The blade feeding is hydraulic damping drive with large processing range. And the maximum cutting length is 3700mm. Its dual heads cut 45° and 90° angles simultaneously, delivering clean, burr-free edges with imported carbide blades. Fitted with stable linear bearings and air-hydraulic feeding, it maintains consistent dimensional accuracy across a 500–3700mm cutting range. The double head aluminium cutting machine suits small and mid-sized aluminum fabrication shops pursuing steady mass production without overspending.

Features
Priced USD 3300 to 3900, this aluminum window machine adopts a thick welded steel base to suppress cutting vibration. Each head mounts a standard 450mm hard alloy saw blade rotating at 2800rpm, capable of 45° and 90° cutting. Sliding units use wear-resistant linear guides for smooth head movement. Pneumatic clamps with follow-up brackets firmly fasten long aluminum profiles. A digital counter displays cutting lengths in real time, while full protective covers and emergency stop switches ensure operational safety. All built-in pneumatic and electrical parts are standard industrial accessories, requiring no extra purchases for regular window production. If you have any other needs, please feel free to contact us.
Why Choose LJZ2-450*3700A Aluminum Window Cutting Machine
01 Imported Carbide Saw Blade
This aluminum double head cutting saw is equipped with a 450mm imported carbide-tipped saw blade (120 teeth) designed for aluminum extrusion cutting. The micro-grain carbide tips stay sharp through thousands of cycles, delivering clean, chip-free cuts within ±0.1mm tolerance. It lasts 2–3 times longer than standard blades, reducing replacement downtime and long-term consumable costs.
02 Imported Linear Guide Rail & Bearing Pair
Both cutting heads run on high-precision imported linear guide rails with sealed bearing blocks. This zero-play rolling system ensures perfectly straight head travel across the full 3700mm working length, delivering consistent, repeatable cut accuracy even under 8-hour daily production — essential for batch window fabrication where every frame must match.
03 High-Accuracy Main Shaft
Each head features a precision-ground main shaft with matched angular-contact bearings, running at 2800rpm with minimal radial runout. The vibration-free rotation produces cleaner cut edges, less burr and reduced blade wear, while lowering noise and eliminating chatter marks — so finished frames need little to no deburring before assembly.
04 Air-Hydraulic Damping Feeding
The head feed system uses air-hydraulic damping cylinders for steady, uniform cutting speed (0–80mm/s) throughout the entire stroke, regardless of profile thickness. Unlike pure pneumatic feeds that can jerk or stall, the aluminum window cutting machine delivers smoother cuts, longer blade life and no profile deformation. Damping force adjusts to match different alloy hardnesses.
05 Auto-Opening Safety Guard
A fully enclosed protective guard opens and closes automatically with each cutting cycle, shielding operators from flying chips and accidental blade contact without slowing workflow. Interlocked with the control system — the saw won’t start unless the guard is fully closed — it meets CE safety standards and eliminates the risk of operators removing guards to speed up production.
06 Auto-Induction Middle Supporter & Follow-Up Clamp
An auto-sensing middle support rises automatically when long profiles are loaded, preventing center sagging during cutting. The follow-up clamp moves in sync with the head to hold profiles securely right up to the cut line. Together, they let one operator handle 6-meter profiles alone while maintaining full-length alignment accuracy.
07 Imported Linear Guides with 45° & 90° Cutting
High-grade imported linear guide pairs on both head travel and angle positioning deliver micron-level accuracy and a service life of tens of millions of cycles. Each head swivels between 45° and 90° with quick-lock positioning, handling mitre joints, right-angle frames and curtain walls without retooling — maximizing equipment utilization for fabrication shops.
