Takumi’s U series of 5-axis machining centers are consistently designed to meet mold and die requirements as well as enable fast and precise machining of workpieces with high surface quality.
One of the outstanding features of Takumi’s compact U series is its pronounced mechanical and thermal stability. The U 400 and U 600 models have a portal design, whereas the U 800 features gantry construction. As a result, the machining centers are extremely robust and have a high level of structural rigidity, which in turn allows for highly precise and dynamic production.
The primary differences between the versions ─ in addition to their design ─ have to do with the sizes of their rotary tables as well as the maximum table loads. Moreover, the U 800 is driven on the A and C-axes by means of torque motors. What do all the designs have in common? The direct drive units feature high drive torque and powerful clamping torque. They are also virtually wear-free and therefore require very little maintenance. Included in the standard equipment of the U series are glass scales, an oil cooler for the spindle, and the internal coolant supply through the spindle assembly. This makes the spindle resistant to high temperatures during prolonged program operating times in addition to its already smooth running characteristics.
As is the case with all Takumi machines, the U series also features a Heidenhain control system that allows for programming in dialog and in parallel mode and also includes functions for free contour programming and ISO-NC programming.
About Takumi
Founded in 1988, Takumi Machinery Company Ltd. is a mechanical engineering company that is based, and operates, in Taiwan. The company develops and manufactures high-speed CNC portal machining centers, principally for tool-making and mold-making applications. All the components used in these machines originate from first class brand manufacturers and specialist suppliers. In July 2015, Takumi was acquired by HURCO, the American CNC machinery manufacturer.

Boehlerit, Austrian development pioneer for cutting materials made from carbide, is creating a strong impulse for the aluminium sector. At the EMO in Hanover, the Kapfenberg-based company presented two additions to its existing aluminium programme in the form of the BWN10M and the BCN10M, both of which explore new avenues in terms of grades, systems and indexable insert design. The new cutting material solutions BWN10M and BCN10M are manufactured for the premium segment, leveraging the wealth of experience held by Boehlerit and fulfilling the most stringent quality requirements. They are intended as high-end solutions for the milling of aluminium, aluminium alloys and non-ferrous metals.
Three face milling systems (ETAtec 45P, THETAtec 45N and ISO 45P) and four edge milling systems (BETAtec 90P Feed, DELTAtec 90P Feed, ISO 90P and ZETAtec 90N), result in an extended tool portfolio whose base body may be fitted with uncoated (Si content < 6%) or coated (Si content > 6%) indexable insert solutions.
The uncoated BWN10M grade is ideal for the processing of non-ferrous metals, aluminium and aluminium alloys (Si content < 6%). Thanks to the specially designed, positive indexable insert geometry, this grade has particularly soft cutting properties. Furthermore, built-up material on the cutting edge is prevented through the use of premium grades with a high level of wear resistance, paired with highly precise manufacturing technologies with regard to the sharpness and design of the cutting edge as well as optimised chipping properties.
Smart production in combination with HRC (Human-Robot Collaboration) and mobile robotics offers new scope for substituting rigid production concepts with intelligent, highly flexible processes. This enables manufacturers to manage production as it is forced to adapt to increased variation. In the future, users will be able to produce more economically, flexibly and efficiently than ever before.
It is, however, a prerequisite for the implementation of innovative production strategies that robot manufacturers respond in timely fashion to the demands of industry and resolutely pursue developments in the field of collaborative robots and mobile platforms. In recent years, Stäubli Robotics has been systematically working on the implementation of pioneering Industry 4.0-compatible solutions.
An outstanding example of Stäubli R&D in this area is the HelMo mobile robotic system, which enables companies from a variety of industries to realize a whole raft of applications – including HRC operations – more efficiently and economically than ever before. This mobile robot is already making a decisive contribution to the replacement of existing, relatively rigid production structures and to the facilitation of new ultra-flexible concepts.
Yet another plus point: HelMo is itself so versatile that, as a universal production assistant, it can perform a wide range of tasks under almost any environmental conditions. The only prerequisites for this are workstations that are adapted for HelMo use and that have the necessary calibration points for the self-adjusting system.
The mobile robot can take on an assortment of different tasks within a single shift. It independently approaches the individual workstations and, after a brief calibration, carries out its assigned task with an accuracy in the tenth-of-a-millimeter range. Able to perform all manner of duties – intralogistics, assembly, machine loading, cell linking, quality assurance – in an autonomous high-speed capacity or in a collaborative role alongside human employees, HelMo is a highly talented all-rounder.
STUDER expands its product portfolio and introduces a new machine to the market - the favorit with a centre distance of 1600mm (63”).
Yamazaki Mazak’s 4kW laser processing machine tool is capable of cutting large structural materials, such as pipe or tube, up to a maximum length of 8,000mm.
