More versions, more power – the new DCX motors and GPX gearboxes

Now even stronger, more efficient and with yet more combination options: There are new additions to the maxon family of X drive products. Several long versions of brushed DC motors, with higher torques and more power, are being added to the product range, together with matching planetary gearheads. Each of the 3-stage versions can now be combined with the next smaller motor. This saves space, weight and costs.
Overview_maxon
Two years ago, maxon motor presented a new generation of brushed DC motors – the maxon X drives. These are extremely powerful, easy to configure online, and ready for shipment within 11 days. Now, four more motor sizes are being added to the existing portfolio. The 14, 16, 22 and 26 mm diameter models are now each available in a long version (L), which offers higher continuous torque and higher continuous output power.

Motors, planetary gearheads
At the same time, maxon motor is presenting four new GPX planetary gearheads, in the sizes 14, 19, 26 and 37 mm, which feature perfect compatibility. All of these gearheads are designed with scaled gear stages. The biggest news is that each of the new 3-stage gearheads can be driven with the next smaller motor. This brings many advantages, as the resulting drive system is smaller, lighter and more economical.

..and much more
That’s not all: Starting immediately, the existing GPX 16 and GPX 32 models are available in various versions and can be equipped with ceramic axles to reduce wear. Customers looking for a particularly low-noise gearhead have the option of choosing plastic planet gears. maxon has also expanded the encoder portfolio. The new ENX 16 Easy absolute encoder is available as an SSI or BiSS-C version, according to the customer’s requirements. All new products are available in the online shop starting immediately. They can be easily configured together with the other maxon X drive products: Customers choose the desired motor, the matching winding, brushes and shaft length, as well as the gearhead and encoder. The configured product is ready for shipment in 11 days or less. For more information, go to dcx.maxonmotor.com.

Innovative two-channel NC system for machine tools with up to five axes

NUM is showing its new two-channel CNC kernel for the first time in the US at IMTS.  There are still two days available to discover it there!

NUM’s latest Flexium+ 8 CNC kernel offers two CNC channels and accommodates up to five axes, four of which can be interpolated.
NUM’s latest Flexium+ 8 CNC kernel offers two CNC channels and accommodates up to five axes, four of which can be interpolated.

Designed specifically for developers of small to medium sized machine tools with four or five axes, the Flexium+ 8 CNC provides an exceptionally cost-effective control solution that in many cases eliminates the need for a second CNC kernel. NUM is also launching a new version of its 3D simulation software which now includes kinematic equations to support advanced 5-axis machining applications.

As if many kernels
The Flexium+ 8 CNC kernel offers two CNC channels and accommodates up to five axes, four of which can be interpolated. At any one time, either CNC channel can be used to control a spindle motor and four axes, instead of the full complement of five axes. This control flexibility helps designers to lower the cost of machines with complex synchronisation requirements. For example, on a grinding machine, one channel could control two X/Z axes and a spindle to perform the grinding functions while the other channel controls two rear mounted U/W dressing axes. Each channel can either run its own part program asynchronously and operate autonomously – much as if it had a dedicated CNC kernel – or the two channels can be synchronised. Control of one to five axes, or a spindle, can be passed on-the-fly from one channel to the other, to maximise use of available hardware resources.

Dedicated simulation software
For maximum flexibility, NUM offers two versions of Flexium+ 3D simulation software. One is designed for standalone use without a CNC system, as a production planning tool for verifying part programs. The other is fully integrated with the Flexium+ HMI (human machine interface) and is connected to the machine’s CNC system. Unlike many competitive CAD/CAM visualisation systems, this uses the NC code that is being processed by the CNC interpolator to create a true real-time representation of machine operation. Part programs can be simulated at the same time that other programs are being executed on the machine, and the same part program can be executed and simulated simultaneously. The simulator visualises the tools, the machine’s kinematic properties and the work piece blank as 3D volumes, and shows the TCP (tool centre point) and material removal as the tool moves along the machining path defined by the part program.

.

The latest release of NUM’s Flexium+ 3D simulation software includes algorithms for the RTCP function to support advanced 5-axis machining applications.

Standard components to form production systems

Usable flexibility through practical design and consistent modularity – for the efficient production of cookware, Fissler relies on standardised presses and pneumohydraulic drive technology from Tox Pressotechnik.
Success story tox
Since cookware has developed from a simple cooking device to a more design, technology and function orientated consumer item, completely different demands are placed on it. These in turn can only be met by a comparably high material, production and quality assurance effort. Particularly as the educated customer is well prepared to pay the respective price for functionality and quality for pans and pots.

Nowadays’ challenges
However, the market for cookware is also marked by a globally large competition, which is why manufacturers must pull out all the stops to ensure competitiveness in the long term. This applies on the one hand to design, functionality, quality, durability and suitability for different kitchen systems (electric cookers with plate, ceran, or induction hob or gas cookers) and energy efficiency, and on the other a preferably rational and efficient production technology. This happy symbiosis is represented by Fissler GmbH in Idar-Oberstein, Germany, which is on the road to international success with its cookware, based not least on a high manufacturing depth. In order to meet the self-imposed high requirements of quality and productivity, Fissler rely on qualified and committed personnel as well as a state-of-the-art and largely highly automated machine park.

From the Tox standard range
The sales representative responsible for consultation and application at Tox Pressotechnik, Marco Unger, was able to offer economical solutions for all machining tasks from the standard range of Tox-Press Systems and pneumohydraulic press force drives Tox-Powerpackage, following an analysis of Fissler’s requirements, in close cooperation with the company headquarters.

Individual process solutions from the construction kit
With the 2-column press of type MBG 08, 150,000 aluminium round blanks are machined every year (raising of the inner edge), to be able to press in stainless steel round blanks into the said aluminium round blanks with the other two 2-column presses in the next work step. The basic equipment of the two similar presses is thus flexible that pans (approx. 90%) as well as pots (approx. 10%) can be machined with them.

Repeatability of 0.5 µm over a 500 mm travel range

For precise positioning tasks in precision fabrication and automation, PI (Physik Instrumente) now offers the M-417 stage with a repeatability of 0.5 µm over a 500 mm travel range.

The new positioning stage from PI for high precision with 500 mm Travel Range.
The new positioning stage from PI for high precision with 500 mm Travel Range.

The drive of the M-417 comprises an efficient ActiveDrive DC motor with integrated 24 V amplifier that acts on the ball screw. Thanks to this structure, the stage achieves a velocity of 100 mm/s and is at the same time designed for high duty cycles. The recirculating ball bearings allow for a very high guiding accuracy of 100 µrad over the entire travel range. An incremental, motor-shaft-mounted rotary encoder controls the position with a unidirectional repeatability of 0.5 µm. The M-417 stage is 120 mm wide and 56 mm high. Its stress-relieved aluminum base ensures the stage’s high stability.

Efficient Drive Principle: DC Motors with ActiveDrive
By eliminating power losses between the amplifier and motor, the ActiveDrive System achieves an increased efficiency. The motor is controlled via pulse-width-modulated (PWM) signals. The operating voltage is obtained with an amplifier integrated in the motor case. Costs are reduced and the setup is more compact, because no external linear amplifier is needed. In addition, noise radiation is eliminated, since amplifier and motor are mounted together in a single shielded case.

Assets:

  • High duty cycles and velocity to 100 mm/s
  • Low crosstalk, ±100 µrad over the entire travel range
  • Efficient ActiveDrive DC servo motor
  • Direction-sensing reference point switch
  • Design resolution to 0.5 µm
  • Min. incremental motion to 0.5 µm
  • Noncontact limit switches

Automated die positioning increases bending machine productivity

Hannover Messe Day 5 – Production in the metalworking industry has become increasingly hectic. Contractors and production departments must produce parts in smaller lot sizes and at a faster pace. Today I’ve discovered components to help machines manufacturer being more efficient.

Trumpf is the world‘s leading producer of machine tools for the metalworking industry, and they have responded to the plight of their customers by offering machine design innovations that improve productivity and efficiency.
Trumpf is the world‘s leading producer of machine tools for the metalworking industry, and they have responded to the plight of their customers by offering machine design innovations that improve productivity and efficiency.

Their TruBend Series 5000 bending machine, for instance, is a press brake that includes an optical positioning aid making it easier to switch to a new part geometry. This machine also includes an automatic angle measurement system that helps operators maintain desired geometries, beginning with the very first part.

A complete process
Press brakes bend metal by vertically pushing a punch into a v-shaped die. This deforms the sheet metal located between the punch and die, thus creating an angular bend. Taking a piece of sheet metal that has previously been bent to a 30° angle and placing it between two flat punches creates a fold. A typical production application will require dies be repositioned to change between the bend and the fold function. Repositioning dies quickly is not the only concern – positioning must also be as accurate as possible to maintain quality of the parts produced. Trumpf has achieved quick and precise positioning with Halstrup-Walcher GmbH positioning systems „LPE“.

Positioning systems for nearly all applications
Two of these precision powerhouses (“powerhouses” because they have to generate up to 1000 N of lifting power) position the heavy lower tools to within 0.05 mm – and in just seconds. Keeping the die from tipping is crucial, which is achieved by the parallel positioning systems being well synchronized.Not only are these positioning systems designed for precision and efficiency—long product life is always a goal as well, ensuring superior reliability of the entire machine as it turns out precise metal bending products even after 10 or 15 years.

To be discovered at Hannover Messe today on the Hall 15, Stand F36.
