CNC portal milling machine HNC 47.82 from Hammer®- technical data and precision check | Felder Group

hello once again and welcome dear friends of the 
Felder Group today we are going to show you the   hammer HNC from the technical perspective 
the dimensions are generous despite its small   external dimensions it offers a large working 
area especially at the height of 160 millimeter   ideal also for shipping and it fits exactly on a 
euro pallet delivery is easy and economical and   even though it weighs approximately 80 kilos it 
can be placed anywhere in the house or workshop   by just two persons even the way shows how 
solid the construction is designed the base   frame consists of the large extremely robust 
t-slot aluminum table due to the T slots almost   unlimited opportunities of mounting and clamping 
are possible extremely flexible even for self-made   mounting methods as well as for your personal 
preferences on how you want to clamp furthermore   all key parts of the basic construction are made 
of solid steel which in combination with the   generous aluminium elements results in enormous 
torsional rigidity this torsional rigidity is   unique in this machine class just like on 
the big production machines we have mounted   two trapezoidal linear guides on all of the three 
axes these profile linear guides not only provide   for stability they are also very precise and 
above all and most importantly they ensure   repeatability they are designed large enough to 
absorb even the greatest forces during machining   another huge advantage because of lifetime 
lubrication is no maintenance and insensitive   vd – contamination by the way repeatability each 
axis is equipped with our innovative trapezoidal   thread nuts – nuts pre tensioned with Springs 
which especially reduced the axial and reverse   backlash to a negligible minimum the result 
is precision without compromise the axes are   driven by large dimensional stepper motors the 
drive unit is decoupled from the stepper motor   using a special tooth belt and is therefore 
vibration free we have paid attention to the   largest possible arc of contact so that slipping 
is impossible even under the greatest loads the   optimal positioning of the drive in the set axis 
has the additional advantage of reducing the   overall height of the machine connection panel 
the open interface with db25 connection makes   our agency compatible with most control systems 
on the market safe the emergency stop connection   for tool length sensor optional extension for a 
fourth axis as well as an auxiliary port for even   more options available there are three choices of 
tool drives the standard version with one kilowatt   and manual speed control or the version with the 
quick-release fastener also with one kilowatt and   speed control via CNC software or the 2.2 kilowatt 
high frequency spindle version with a large a   mounting head for tools up to 16 millimeter shaft 
diameter for those who want to use their own drive   systems we also deliver without motor these 
are the most important facts that make the Hama   agency an extremely reliable tool with highest 
precision and durability repeatability vibration   free torsional rigidity robust strong sighs and 
made in Austria so when the agency arrives at   your place it is already assembled adjusted and 
lubricated which means unwrap it plug it in and   you're ready to go however in order to give 
the technical data or theory and expression   we have of course also included a practical 
test following the motto finest precision put   into a nutshell and by the way don't forget to
