JIH-T3 Automatic Double Head Mitre Sawing Machine for Aluminium | JIH-I, Taichung, Taiwan

The JIH-T3 is an automatic double head tilting saw for cutting aluminium profiles. It has two saw heads that can work individually or together, so you can cut the length and the angle on both ends of a profile in a single operation.

The machine positions itself automatically to the required cutting length, which reduces manual measuring and handling. Three axes are servo-controlled: one servo positions the machine length, and one servo swings each of the two saw blades. The X axis moves on a linear guideway to keep positioning accurate. The tilting range covers 22.5°, 45°, 90°, and 135° cuts, and the double blade mitre is set automatically within ±0° to 45°.

The maximum cutting length is 4,500mm, with 6,500mm available as an option. Optional equipment includes automatic feeding (push), a chip collector, and saw blades, and JIH-I notes that the mobile saw heads can also be set to feed and cut automatically.

Why Choose a Double Head Mitre Saw?

Frames made from aluminium profile need both ends cut at the right angle and the right length. On a single-head saw that means two set-ups per piece, or flipping the profile, which slows work and introduces error.

• Both ends in one pass. Two heads cut both ends together or separately.
• Automatic length positioning. The machine sets itself to the programmed length, so operators aren't measuring each piece.
• Servo accuracy. Servo control on all three axes gives cutting length precision of ±0.15mm.
• Flexible angles. The tilting range covers 22.5° through 135°, so the same machine handles mitred and straight cuts.

Frequently Asked Questions

What does "double head" mean?
The machine has two saw heads, so both ends of a profile can be cut to length and angle in one operation. Each head can also be used on its own.

What angles can it cut?
The tilting range is 22.5° to 90° to 135°, and the double blade mitre is set automatically within ±0° to 45°.

How accurate is it?
Cutting length precision is ±0.15mm.

What is the longest profile it can cut?
4,500mm as standard, with 6,500mm available as an option.

Does it position itself to the cutting length?
Yes. It has an automatic positioning function, driven by a servo-controlled length axis.

What options are available?
Automatic feeding (push), a chip collector, and additional saw blades.

How heavy is it?
2,350kg net and 2,450kg gross, with dimensions of 6,750 × 1,700 × 1,650mm.

Is financing or staged payment available?
Yes. A deposit secures your order and begins production, with the remaining balance due only once your machine has been built, inspected, and is ready to ship.

Should I buy new or used?
This model is available new, from a manufacturer that has built aluminium sawing machines since 1971.
