The "GK-HCZ" Zero Burr Drill is a revolutionary hybrid drill that finishes everything from pilot hole processing to deburring and reaming in a single operation!

The Zero Burr Drill is a revolutionary hybrid drill that enables one-shot processing without a pilot hole, suppressing burrs and achieving hole accuracy of H6 or better. This is a case study of processing carbon fiber CFRP, which is considered difficult to machine. Carbon fiber tends to produce severe burrs, delamination, and chipping during processing, and the cutting tools also wear out quickly. By using the 'GK-HCZ', we can suppress burrs, delamination, and chipping, successfully achieving clean hole drilling with just one carbide drill! [Processing Case] ■ Tool Used: GK-HCZ DLC (Drill for CFRP) ■ Coating: DLC ■ Material: CFRP (Thermosetting Carbon Reinforced Plastic) ■ Cutting Conditions: S=2500 F=50 ■ Size: φ3.0 to φ12.0 ■ Regrindable Simultaneous drilling of CFRP and aluminum can also be done cleanly without delamination. Regrinding is possible, allowing for regeneration. *For more details, please refer to the PDF document or feel free to contact us.

No burrs with a single perforation without a pilot hole! Even with a slightly bent pilot hole, perforation can be done straight while correcting.

The "Zero Buri GK-HCZ Series" is a hybrid drill for CFRP that reduces burr removal work, enabling cost reduction and high-efficiency production. It suppresses heat with a wave effect, achieving excellent cutting performance. It has good bite and features composite R shinning for precise positioning. Additionally, it is economical as it can be re-sharpened. 【Features】 ■ No burrs produced with one-shot drilling without a pilot hole ■ Hole accuracy is H6 or below as long as there is no runout ■ Excellent straightness ■ Can drill straight while correcting even slightly bent pilot holes ■ Jointly developed with the Fukui Prefectural Industrial Technology Center *For more details, please refer to the PDF document or feel free to contact us.

If there are no burrs, the hole accuracy is below H6! It allows for good engagement and precise positioning with composite R finishing.

The product we handle, "Zero Buri GK-HCTZ," is a hybrid drill for CFRTP. The recommended cutting conditions are cutting speed V = 20 to 40 m/min and feed per revolution f = 0.02 mm/rev. *Wet and mist drilling. It allows for one-shot drilling without a pilot hole, producing no burrs, and as long as there is no runout, the hole accuracy is below H6. Additionally, the wavy shaped effect significantly reduces heat with a large waveform effect, achieving outstanding cutting performance. 【Features】 ■ Taper End Mill - A taper end mill that eliminates subtle burrs to achieve zero burrs. ■ Extreme Keeness Blade - A special R-shaped design that disperses cutting resistance, reduces heat, further minimizes burrs (delamination), and extends the lifespan of the R blade. ■ Special Waved Drill - A wavy drill that achieves hole accuracy below H6 with 1/4 of the cutting resistance, effectively minimizing burrs. *For more details, please refer to the PDF document or feel free to contact us.

Suppress heat with waveform effects and achieve outstanding cutting performance! Waveform drill that minimizes burrs finely.

The "Zero Bari GK-HCZ" we handle is a hybrid drill for drilling CFRP. It allows for one-shot drilling without a pilot hole, producing no burrs, and achieving hole accuracy of H6 or better as long as there is no runout! It also accommodates cross holes on the sides and can be re-sharpened, leading to cost reductions. When combined with aluminum, it can drill from both the aluminum side and the CFRP side. With excellent straightness, it can correct for slightly bent pilot holes while drilling straight. This product was developed in collaboration with the Fukui Prefectural Industrial Technology Center and is patented. 【Features】 ■ Ripple Shaped Effect - The wave effect suppresses heat and achieves outstanding cutting performance. ■ Extreme Keeness Blade - The special R shape disperses cutting resistance, reduces heat, and further minimizes burrs (delamination), extending the lifespan of the R blade. ■ Special Wave Drill - With cutting resistance reduced to 1/4, it achieves hole accuracy of H6 or better and minimizes burrs with its wave-shaped drill. Recommended cutting conditions are cutting speed V = 20-40 m/min and feed per revolution f = 0.02 mm/rev. *Dry drilling *For more details, please refer to the PDF document or feel free to contact us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

This is an air leak tester for battery cases of electric vehicles (EVs). The battery case has the characteristic of being "large with a significant internal volume, and its structure may deform due to internal pressure." As a result, air leak testing generates "noise caused by its large size and capacity" and "noise caused by expansion or deformation due to internal pressurization." To mitigate this noise, this device features a newly developed smoothing function and a linear fitting correction function used in combination during measurement. Additionally, to achieve low-pressure control that is difficult to manage and to expand flow for large volumes, we provide a bypass box (CBU-600) equipped with an electro-pneumatic regulator for precise pressure control and a pressurization valve with a large effective diameter to supply high flow rates. Measurement methods: Work-Work comparison, Work-Master comparison, Fixed Master comparison Measurement pressure range: 10 kPa, 20 kPa, 50 kPa (depending on specifications) Gauge pressure sensor accuracy: ±2% F.S. Differential pressure sensor accuracy: ±0.5% F.S. Group settings: 0 to 31 groups Power supply voltage / Power consumption: AC100 to 240 V / 100 VA
