HITECO METALTECH MX SPINDLES WITH IM SMART SENSOR
For the first time, Hiteco enters the world of " other materials " , and in particular metal and light alloys, with the MX
electrospindles. The advantages of this new Metaltech range include:
- Suitable for machining metal, aluminium and light alloys;
- Power up to 42 kW and high torques up to 67 Nm;
- Front bearings cooling circuit;
- Available with on-board encoder, air tool, MQL (minimum quantity lubrication), oil mist and CTS (coolant through
spindle);
- Synchronous spindles with HSK 63A and on-board encoder.
Hiteco's other new development, the iM Smart Sensor, can also be installed on the Metaltech spindles. This intelligent sensor constantly monitors the
machining conditions of the spindle it is installed on. It can support the whole production process, monitoring the main parameters that the spindle works
on: vibration and temperature. This process monitoring instrument lets users easily identify malfunctions and consequently reduce unexpected machine
down times. www.hiteco.net
TEMCO ULR/ULW: LIGHT, PRECISE AND
DURABLE INTO THE FUTURE
The ULR and ULW deflection rollers from Saurer Technologies
Engineered Bearing Solutions (EBS) are high-precision
components made in Germany. These products from the Temco
line are characterized not only by a variety of
sizes, but also by different materials - such as
carbon or aluminium. They are mainly used
in the textile, hygiene, printing, tobacco and
packaging industries. The rollers and rolls
from Saurer EBS are particularly suitable for
the production of round or prismatic cells
in the manufacturing process of lithium-ion
batteries. They can guide and divert the foils extremely precisely and
guarantee reliable production thanks to exact concentricity, precise
cylinder shapes and squareness. Long service life and lifetime
lubrication of the components not only save maintenance costs, but
also minimize machine downtime. Temco components impress with
the highest performance, especially in demanding start-stop processes
such as the winding process of round or prismatic cells. In addition to
winding, the rolls and rollers also cover complex process steps such
as coating, drying and calendering. With the products from Saurer
EBS, the battery industry is not only well equipped now, but they also
guarantee maximum performance on the production lines for future
developments, such as the production of the all-solid-state or lithium-air
battery variants. www.saurer.com
CONTACT-FREE ULTRASONIC
TESTING SYSTEM
XARION Laser Acoustics developed an integrated solution for contactfree
ultrasonic testing of composite parts based on its Laser-Excited
Acoustics (LEA) technology. In LEA, a short laser pulse generates a
broadband ultrasonic waveform directly in the part.
For detection, the company's proprietary optical
microphone measures the ultrasound signal in air
with a very broad frequency detection bandwidth
of 2 MHz.
The combination of excitation laser and optical
microphone leads to several advantages:
- Measurements on composite parts can be
performed with sub-mm resolution and high
sensitivity without using a coupling liquid;
- The technology is immune to surface conditions such as reflectivity and
roughness;
- It is robust against off-normal misalignment of up to 5° with respect to the
sample surface;
- The LEA probe is very compact because both excitation laser and optical
microphone are fibre-coupled.
These features make LEA a flexible solution for contact-free ultrasonic
testing of a large variety of monolithic composite parts as well as honeycomb
sandwich structures. The probe can be mounted on an industrial robot for
scanning large parts with complex geometries, and for very high scanning
speeds, it can also be configured as an array. www.xarion.com
XTREME-D, A NEW GENERATION OF CARBIDE TOOL COATING
N-POL has been testing different carbide grades for years, resulting in the use of a unique composition of sintered carbide that
significantly increases tool life when machining difficult-to-machine materials. Cemented carbide tools for composite material
machining applications require special geometries and, above all, protective coatings as all machining is done dry, which
results in increased friction and temperature.
XD is a new coating based on diamond-like carbon (DLC) with additional layers increasing the hardness to almost 6000 HV. It is
a combination of a basic protective coating and additional nano-layers of other components to obtain a durable and strong structure
resistant to abrasion and a wide variety of chemicals contained in composites that have a negative impact on the bonding of the
carbide. XD is a micro-thin coating that allows the tool blade to maintain the cutting edge sharpness and provide a high degree of slip during machining.
It provides long tool life, low cost and maximum cutting performance. Above all, the coating protects against high temperatures and carbide oxidation,
which have the most negative impact on cutting tool performance. XD has twice the temperature resistance during operation compared to basic coatings,
which gives it an advantage over tools with earlier generation versions of the DLC coating. www.npol.com.pl
