At Nikken, we aim to “assist the customer’s ‘NEXT advancement’” through solution oriented sales where we quickly detect and offer the next improvement theme for our users. We offer a one-stop total solution for processing by taking advantage of the strengths of manufacturers that create not only tools, but also a wide range of M/C peripherals ranging from rotary tables to reamers. To further assist our customers, we have also created new videos to introduce application methods that can be immediately utilized for both existing and new products.
We’ve recently introduced a new high rigidity model of the “Mini-Mini Chuck (MMC)” called the “Mini-Mini Master Chuck” that supports a grip diameter of φ10 to 20mm. The Mini-Mini Chuck realizes a slim body with low run-out and high gripping force without using a nut by its design to pull the collet directly from the spindle side. Similar to the conventional MMC, the Mini-Mini Master Chuck is effective for high-speed rotation and high-precision end mill machining such as metal casting. Its high rigidity also reduces chatter during heavy cutting which makes it very effective for processing difficult-to-cut materials such as stainless steel.
The eMAC series significantly reduces setup time by quickly and accurately adjusting the diameter with a digital scale. Compared to the dial adjustment type that requires skill and experience, it can minimize human error by accurately displaying the amount of slide movement digitally. One head can even handle up to φ6-φ110 with a switch of the attachment. These specifications are ideal for processing prototypes and production of many types in small quantities. The latest eMACP is IP69K compliant with significantly improved waterproof and dustproof performance. It achieves the highest level of protection against dust contamination and high-pressure / high-temperature water intrusion, and is designed to be less susceptible to harmful effects on internal digital circuits even in harsh machining environments with coolant injection.
The 5AX-2MT-182-250-205B is a compact multi-axis tilted CNC rotary table with a face plate diameter of Φ180, making it the world's lightest rotary table with a mass of only 240 kg. This new model also improves upon conventional machines by accommodating spindle taper BT30 Small M/C which was previously difficult to install. Maximizing the limited space of small M/Cs, it contributes to improving automation and cutting labor cost through simultaneously processing multiple workpieces. This process consolidation also further contributes to mass production – becoming useful in various scenes including automobile parts and accessory processing.
The machine spindle’s pull-in force may decrease due to deterioration of the internal disc spring and of the booster mechanism in the tool clam device. When the pull-in force decreases, the static rigidity also decreases. This can then cause deterioration of cutting force, machining accuracy, and blade life. With the Portable Pull-in Force Measurement Tool, it will be possible to proactively prevent such deterioration and damage by measuring the pull-in force on a regular basis. Best of all, the measuring will only take one second in addition to its merits of being battery-powered, compact, and lightweight.
If you use the J-type nut and J-type cap in combination (which are both add-on options for slim chucks), you can inject coolant through a standard collet even with a cutting tool that does not have an oil hole. A tornado-shaped coolant is sprayed from the unique triangular groove equipped on the cap, and the coolant does not scatter even in the high-speed rotation range exceeding 20,000 rotations while blowing the chips off. This makes it very effective in high-speed cutting of aluminum, which emits a large amount of chips, and greatly contributes to automation since the machine does not need to stop from cleaning or chip clogging.
As the number of skilled technicians decrease and the shortage of personnel becomes a social problem, the tool presetter is gaining the spotlight now more than ever as a trump card to improve the machine operation rate and productivity by externalizing the process of tool measurements that was previously done within the machine itself. Another topic gaining attention is the tool management system which takes field rationalization one step further. Nikken's eTOP tool management system uses QR codes to manage tool IDs and share correction data between machine tools and tool presetters without introducing a large-scale system. Utilizing this system in combination with the corresponding Nikken Tool Presetter can prevent defects and accidents caused by inaccurate records by operators – thus further contributing to efficiency.
Nikken's original milling chuck offers both a strong gripping force due to the multi-lock system, and a compact tightening bracket that demonstrates its strength even in a high-speed machining range. It achieves high-efficiency cutting, low run-out, and excellent gripping force both at the nose and the bottom due to its body rigidity. In addition, the slim chuck uses a unique 8 ° taper collet that is highly centripetal and provides a strong grip even with a small torque, achieving approximately twice the grip compared to conventional collet chucks. This can be widely used as a universal holder that demonstrates its power in all applications such as end milling, drilling, and reamer processing – offering a higher quality basic tool holder that can act as a core of machining sites.
It is NIKKEN’s unique design, superior to traditional steel worm screw. Solid carbide worm screw is allowed longer life and minimal wear compared to traditional worm system to use specially hard material. This alongs with the hand pairing of the custom made steel worm wheel to eliminates backlash. The material used for the NIKKEN worm wheel is custom made steel, specially hardened and ion nitrided on the teeth. As a consequence, frictions between the gears are eliminated. Our thoroughgoing passion for high rigidity and high precision results in products of excellent durability that retain their precision even after long-term use. This boosts the operating ratio and cuts maintenance costs, contributing to a substantial reduction in costs overall.
The cemented carbide radical mill reamer realizes a high-speed, long-life, high-precision reaming by applying a TiCN coating with low friction coefficient and hardness of HV3500 to the carbide blade with ultrafine particles. It is also compatible with environment-friendly water-soluble cutting fluid.Furthermore, Nikken's unique spiral shape reduces chattering and enables smooth chip discharge. The specification with an end blade that corrects the bending of the pilot hole realizes outstanding hole dimensional accuracy and surface roughness regardless of the skill of the operator. This reduces the defective rate and greatly contributes to the rationalization of the site.
Unlike the general rust-preventive holders that are plated, Nikken's black holder is made by a special process in which tri-iron tetroxide (Fe3O4) and ferric oxide (Fe2O3) are absorbed into the holder surface to form a rust-proof and corrosion proof coating film. It is created with the idea of "controlling rust using rust". The coating is only 1 to 2 μm thick and has no effect on the quenching hardness or the accuracy. Moreover, the special coating protects the holder from deteriorating over time, freeing it from the possibility of peeling off like other plated holders.This Rust-proof treatment is available in Nikken's standard products such as milling chucks and slim chucks.
