JR-550Q Single-Head Corner Saw: Precision Cutting for Aluminum Profiles
In the aluminum processing industry—from door/window frame fabrication to furniture component production—small-batch, high-precision corner cutting is a critical but often labor-intensive step. Traditional manual corner saws require constant operator adjustment, leading to ±0.5mm angle errors and burrs that demand post-processing; exposed saw blades also pose safety risks. The JR-550Q Single-Head Corner Saw resolves these pain points: as a specialized single-head angle cutting machine, it integrates safe hidden blades, automated lubrication, and electronic angle control to deliver consistent, burr-free cuts with minimal operator intervention.
1. What Is the JR-550Q Single-Head Corner Saw?
The JR-550Q Single-Head Corner Saw is a dedicated industrial machine designed for 35°–145° arbitrary-angle cutting of aluminum profiles (1–10mm thickness). Unlike generic saws, it is optimized for small-to-medium batch processing: its compact 1200×1000×2000mm frame fits in workshop spaces as small as 5㎡, while its 4KW cutting motor delivers sufficient torque for thick aluminum profiles (up to 350mm width).
Its defining design choice—the hidden saw blade—addresses a top industry safety concern: the blade operates within a enclosed chamber, allowing safe up-and-down movement without exposing operators to rotating components. This feature alone reduces workshop safety incidents related to sawing by 90% for users of the JR-550Q Single-Head Corner Saw.

2. Core Features of the JR-550Q Single-Head Corner Saw
The JR-550Q Single-Head Corner Saw stands out for 3 industry-leading features tailored to aluminum processing needs:
2.1 Safe Hidden Saw Blade Design
The enclosed saw blade chamber ensures operators never come into direct contact with the rotating blade during operation. The blade moves vertically (up/down) to cut clamped profiles, eliminating the risk of accidental contact—critical for workshops with less experienced staff. For context, OSHA (Occupational Safety and Health Administration) reports that 60% of aluminum sawing injuries stem from exposed blades; the JR-550Q Single-Head Corner Saw’s hidden design mitigates this risk entirely.
2.2 Automated Saw Blade Spraying
To reduce burrs and extend blade life, the machine features an automatic oil spraying system: it releases a fine lubricant mist onto the saw blade during cutting, cooling the blade and reducing friction between the blade and aluminum. This results in a cut surface roughness of ≤Ra1.6 (burr-free) and extends saw blade life by 30% (from 2,000 to 2,600 cuts per blade).
2.3 Electrically Controlled Clamping & Angle Programming
The JR-550Q Single-Head Corner Saw uses electronic controls for two critical functions:
- Clamping: Pneumatic clamps (adjustable pressure: 5–8kg/cm²) secure profiles without deformation, even for thin-wall aluminum (1–2mm thickness);
- Angle Programming: Operators input the desired angle (35°–145°) via the 4-inch digital display, and the machine calibrates the saw head to within ±0.15° tolerance—eliminating manual protractor adjustments.
A Guangdong-based door frame manufacturer reported that after adopting the JR-550Q Single-Head Corner Saw, angle adjustment time per batch dropped from 15 minutes to 2 minutes, cutting total processing time by 25%.
3. Technical Specifications of the JR-550Q Single-Head Corner Saw
Every parameter of the JR-550Q Single-Head Corner Saw is calibrated to meet small-to-medium batch aluminum processing needs (paired with the JR-650Q for larger profiles):

4. Application Scenarios of the JR-550Q Single-Head Corner Saw
The JR-550Q Single-Head Corner Saw is a staple in 4 key aluminum processing workflows:
4.1 Door & Window Frames
Aluminum door/window frames require 45°/90° symmetrical cuts for seamless assembly. The machine’s ±0.15° angle tolerance ensures frame gaps ≤0.3mm—meeting national building material standards (GB/T 8478-2020).

4.2 Furniture Components
Lightweight aluminum furniture (e.g., office desk frames) uses thin-wall profiles that are prone to deformation. The JR-550Q Single-Head Corner Saw’s adjustable pneumatic clamps secure these profiles without warping, delivering consistent cuts for batch production.
4.3 Curtain Wall Accessories
Small curtain wall brackets require precise 60°/135° cuts. The machine’s electronic angle programming allows operators to switch between angles in 10 seconds, ideal for mixed-batch production of curtain wall components.

4.4 Advertising Sign Frames
Aluminum advertising signs use narrow profiles (≤100mm width) that demand clean, burr-free cuts (to avoid damaging vinyl graphics). The machine’s automated oil spraying ensures the cut surface is smooth enough for direct graphic application.
5. Operation & Maintenance of the JR-550Q Single-Head Corner Saw
The JR-550Q Single-Head Corner Saw is designed for ease of use (1-hour operator training) and low maintenance:
5.1 Basic Operation Workflow
- Turn on the main power and air supply (380V 50Hz; 0.6MPa air pressure);
- Input the desired cutting angle (e.g., 45°) via the digital display;
- Load the aluminum profile into the clamping fixture and press “Clamp”;
- Press “Cut” to initiate the sawing process (the machine will auto-spray oil during cutting);
- After cutting, press “Unclamp” to remove the finished profile.

5.2 Scheduled Maintenance
- Daily: Clean saw blade debris and check oil levels in the spraying system;
- Weekly: Lubricate the saw head’s vertical guide rails with lithium-based grease;
- Monthly: Calibrate the cutting angle using a precision protractor (included with the machine);
- Quarterly: Replace the saw blade if cut roughness exceeds Ra1.6 (tested via surface roughness gauge).
For troubleshooting (e.g., clamp failure), Jiurun Technology provides 24/7 remote technical support (response time ≤1 hour) and a 1-year full machine warranty.
6. Why Choose the JR-550Q Single-Head Corner Saw?
For small-to-medium batch aluminum processors, the JR-550Q Single-Head Corner Saw delivers 3 irreplaceable benefits:
- Safety First: Hidden saw blade design eliminates 90% of sawing-related injuries, reducing workshop insurance costs;
- Cost Savings: Automated oil spraying extends blade life by 30%, while burr-free cuts eliminate post-processing polishing (saves $0.5 per component);
- Efficiency Boost: Electronic angle programming cuts setup time by 87%, allowing 200+ profiles to be processed per hour.



Carlos García –
“As the first Spanish user of the JR-550Q Single-Head Corner Saw, it’s transformed our aluminum window frame production! Previously, manual corner cutting left inconsistent 45° angles—every 10 frames needed 2-3 reworks to fit seamlessly. Now this saw cuts precise, burr-free angles in 10 seconds per piece, with zero gaps between frame joints. Our window assembly time has dropped by 60%, and customer complaints about fitting issues have completely vanished. It’s the reliable, high-precision tool our small-scale window workshop desperately needed!”
