COMPOSITE PRO is a laser system designed to project polylines and outlines onto work surfaces and processed items! The projected laser lines are based on CAD data. It is used in many industries for tasks such as positioning during prepreg lamination, indicating machining positions for wood, marking for painting on large products like shipbuilding, and positioning for welding. 【Features】 ■ Projects polylines or outlines onto work surfaces, workpieces, molds, etc. ■ Generates projections based on CAD data, ensuring accurate scale representation. ■ Enables efficient work regardless of industry, material, or product. ■ The laser does not physically touch the workpiece, ensuring cleanliness. ■ Highest precision of ±0.06mm/m. ■ A more economical standard precision of ±0.2mm/m is also available. ■ Minimal and lightweight, making layout changes and installation easy. ■ The small galvanometer mirror allows for high-speed movement, reducing laser flicker. *For more details, please request documentation or view the PDF data available for download.

Fast! Easy! Reliable! By using a shaft without screws, you can quickly complete tasks even if the width of the roll changes. Additionally, by using a taper cone, centering of the spool can be achieved, allowing for tightening that can apply high tension. ■Significantly reduces roll change time. ■Lightweight design makes it easy to handle, even for women. ■Operable with one hand and without tools. ■Easily applies high tension to round shafts (with specified hardness). ■Ideal for driving payoff shafts. ■Not dependent on the rotation direction of the shaft. ■Compact and symmetrical design. ■Maintenance-free. ■Can be installed with non-genuine taper cones; design information is available. *For CAD drawings, you can download in this site. Available in 2D (DXF) / 3D (STEP).

Linear drive nut from Ewing Company (Germany: Joachim Uhing KG & Co. KG). It converts the rotation of a round shaft without threads into linear motion. By specially processing 3-4 bearings with an inner diameter slightly larger than the shaft diameter and arranging them alternately tilted against the shaft, it generates lead through line contact, achieving the same effect as a screw. - No threading required; linear motion is obtained from the rotation of the round shaft. - There is no backlash. - It slips under overload to protect the machine. It is used in the feed of measuring instruments such as three-dimensional measuring machines, door opening and closing mechanisms, and conveying devices. Options for special specifications such as pitch changes, direction changes, additional wipers, and additional free levers are available.

Feeding device, guiding device, and reciprocating device using a plain shaft It converts the rotational motion of a round rod, which rotates at a constant speed and in a constant direction, into linear motion to obtain reciprocating motion. The round rod does not require a screw; linear motion can be achieved by pressing a tilted special bearing against it. Additionally, by changing the orientation of the bearing, the direction of motion can be altered even if the rotation direction of the shaft remains constant. These movements are analogous to the relationship between a screw and a nut, but the travel speed (pitch) can be freely set, and the direction of movement can be reversed at any position. ■ The pitch can be changed by altering the tilt of the bearing. ■ High-speed and smooth feeding can be achieved. ■ There is no backlash. ■ A safety mechanism allows the unit to slip in the event of an unexpected collision. ■ The contact-free lever can release the fixation with the shaft. ■ No control or dedicated power is required (power can be obtained from a parallel rotating shaft via a belt, etc.). ■ Bracketed and non-bracketed options are available as needed.

It is a clamp unit that fixes spools, bobbins, rolls, colors, etc. on the axis, and can also be used for positioning, safety measures, and as a spacer. ■ Fixed with one action, released and removed with two actions ■ Rust prevention treatment with a self-locking mechanism ■ Inexpensive. * If additional tightening or centering is required, or if there are loads or vibrations, please consider "Easy Lock."

This is a broaching tool for hexagonal hole machining. It eliminates the processes of hexagonal hole machining that were previously done by pressing or electrical discharge machining, thereby improving efficiency. We also accommodate special products such as multi-sided hole machining, Torx, square holes, and external hexagonal machining.

The ETS and ETA collets are patented by Technopin and are compatible with HSK and ISO tool holders. The ETA collet is a higher precision type than the ETS collet, featuring a special shape and fewer cuts (grooves), which maintains very low runout and balance, enabling high-speed rotation (max. 100,000 rpm) while achieving high-precision machining.

Generate a fluid that vibrates left and right without using moving parts, thanks to a special structure inside the nozzle! This allows for reduced vibration and noise. Since there are no moving parts, maintenance is unnecessary, leading to a longer lifespan, and there is no need for electrical control or wiring connections. It can handle pressures up to 200 bar and is widely adopted in the car wash and high-pressure cleaning industries. It is also effective as a water nozzle or air nozzle for removing chips inside processing machines. With just one nozzle, you can use various fluids such as water, air, and coolant, making it very economical. Experience the effectiveness of chip removal using coolant (cutting fluid) by replacing existing spray nozzles (fan-shaped). It comes with screw connection sizes of R1/4” or 1/8”, and coupler specifications are also available. Custom products can be accommodated. By improving the chip removal rate and enhancing processing efficiency, it is possible to prevent scratches on processed products, extend the lifespan of cutting tools, avoid line stoppages due to chips, and reduce cleaning time. A demo unit is available for testing.

Hybrid nozzle with straight jet + fan-shaped nozzle! While the fan-shaped nozzle disperses pressure and lowers it, the oscillating jet nozzle can inject a straight jet in a fan-like manner by using only the internal structure of the nozzle. As a result, it can spray over a wide area with the pressure of a straight jet, similar to a fan-shaped nozzle. Since it does not use any moving parts and vibrates left and right without power, the risk of failure is reduced, and its large flow path makes it less prone to clogging, allowing for long-term use. Intermittent operation to impact the work surface and quick switching operations of solenoid valves are unnecessary. This energy-saving nozzle can reduce water consumption by up to 40%. Additionally, it produces low vibration and noise, requires no maintenance due to the absence of moving parts, and does not need wiring connections since there is no electrical control. With just one nozzle, it can use various fluids such as water, air, and coolants, making it very economical. The screw connection diameter is only R1/4”, but custom products are also available. It eliminates the risk of metal contamination during the cleaning process. Currently, it only has a spray angle of 45° at a flow rate of 1.2L/min at 3 bar.
