Leuco t3-System

LEUCO: Revolutionizing Solid Wood Machining at the Highest Level. Discover Cutting-Edge Precision with the LEUCO t3-System - Proven Performance, Proven Products.

LEUCO's t3-System is setting new standards in the machining of solid wood and wood-based materials. Specifically designed for carpenters, furniture manufacturers, and joinery professionals, this innovative solution combines advanced technology with practicality to deliver outstanding performance. From chip-free surfaces to high milling precision, the t3-System is engineered to elevate your woodworking experience.

The new t3-System shank-type cutter is designed for use on CNC machines and joinery machinery. The triangular turnover knives with rounded edges are the decisive feature for the high processing quality of the t3-System shank-type cutter.

The Triangular Form Defeats The Square Form

Two high-quality hole saws were compared in machine use - one with square inserts, the other from LEUCO with triangular inserts. The t3-System tool by LEUCO came out on top. The excellent cutting quality of the cutter due to the arrangement of the triangular indexing inserts for which a patent is pending makes the difference.

Both cutters were put to the test at Weinmann, a leading manufacturer of machines for woodworking. The crucial question was to find out which of the selected hole saws with square or triangular inserts can deliver the more convincing performance. The tools are mainly used for milling of socket holes and cable ducts in beams in frame construction –especially by woodworking companies with joinery machines and multifunction bridges placing high demands on surface and cutting quality.

Increased Feed, Optimum Chip Evacuation And Smooth Surfaces

The test was carried out on a WALLTEC M-300 multifunction bridge in the test department of the machine manufacturer Weinmann. The upper edges of both tools are arranged at an angle of 45 degrees so that drilling and chamfering can be carried out in one step. The equivalent cutter has square inserts in contrast to the t3 system tool from LEUCO working with an efficient and patent-pending arrangement of triangular inserts.

The tool of the competitor was tested with a feed of 8 meters at 12,000 revolutions per minute and a feed of 34 millimeters. However, when the feed was increased to 10 meters per minute, burn marks appeared on the piece of wood due to frictional heat. This was not the case with the LEUCO hole saw which delivered a convincing cutting quality at a feed rate of 10 meters and 12,000 revolutions per minute — with excellent surface quality of the wooden workpiece and chip-free edges at the socket hole.

Another benefit is the excellent chip evacuation without clogging the gullets or overloading the dust extraction. The WALLTEC M-300 had been specifically programmed for spiral plunge-cutting of the tool. This enabled the feed rate of the LEUCO t3-System milling cutter to be increased to 12 meters per minute, which meant that only 30 percent spindle power was required for the entire work process — a considerable saving in energy and less stress for the machine.

Centered Shear Angle, Excellent Edge Quality, No Overcuts

The t3-System turnover knives of the LEUCO hole saw can be positioned at a shear angle which allows to guide the cutting force to the central part of the cutter. This will pull the cutting edges in direction of the workpiece to be machined, which improves the milling quality especially when processing crosscut wood and when cutting across the grain. The tool cuts socket holes and cable ducts in one pass, produces smooth surfaces and excellent edge quality –without overcuts. The cutter is also suitable for sizing and is ideal for processing various materials, such as soft and hard wood, glued laminated timber, and wood and panel materials. Even abrasive gypsum plaster boards can be processed.

The simultaneous drilling and chamfering using the upper cutting edges at a 45-degree angle eliminates the need for time-consuming rework. In addition to the high hole and surface quality, the cutting-intensive arrangement of the turnover knives increases the chip volume and optimizes chip evacuation. Advantages that were also convincing in the comparison test at Weinmann — since then, the woodworking machine manufacturer has preferred the innovative t3-System from LEUCO.

  • Holes made by LEUCO: clear test result for the t3-System cutter – excellent milling quality, excellent edge quality, no burn marks. The chamfer with 45 degrees at the upper edge is produced by the innovative tool in one pass.

  • The t3 system milling cutter has no need to shy away from comparison and is also impressive when it comes to producing chip-free and clean cable ducts.

  • The t3 system passed the stress test with flying colors - the t3 system milling cutter delivers top results at a feed rate of up to 10 meters and 12,000 revolutions per minute.

Indispensable Features of the t3-System

The LEUCO t3-System introduces a range of unique features that set it apart in the field of solid wood machining. Here's what makes it indispensable for professionals:

Exceptional Design for Flawless Results

The t3-System shank-type cutter features triangular, rounded turnover knives strategically positioned at shear angles. This design ensures chip-free surfaces when joining, rabbeting, or freeform milling solid wood and wood-based materials. The result? Seamless, shoulder-free joints and superior edge quality.

Versatile Applications

Ideal for CNC machines and joinery machinery, the t3-System enables a wide range of tasks, including door rabbet production, tenon cutting, specialized joinery, and freeform milling, making it perfect for furniture and stair construction.

Highly Efficient Spiral Plunge-Cutting

The spiral and inclined cutting capabilities allow for precision in producing small cutouts and complex free-form curves with ease, even in tight spaces.

Easy Maintenance

With a user-friendly design, the cutters are quick to maintain. All 18 knives can be removed, cleaned, and replaced in just 10 to 15 minutes using a simple Allen key. This ensures minimal downtime and maximum efficiency.

Durable and Customizable

The triangular turnover knives offer three cutting edges, extending tool life. LEUCO also provides variants tailored for specific needs, including hard and soft wood, laminated wood, and specialty knives for unique applications.

  • Conventional standard tool

    The rectangular turnover knives can only be positioned in a way that the cutting pressure on the workpiece is directed to the outside (see arrows). Consequence: rough edges that have to be reworked.

  • Innovative LEUCO tool

    The triangular turnover knives of the t3-System are arranged in way that the cutting pressure acts towards the inside of the material (see arrows). Effect: very fine edges, no rework required.
