When press brake tooling sourcing a new press
brake the buyer's goal should be to match the equipment to their expected
requirements and use,plus get the best value for their investment.This means
obtaining an excellent quality product with proper features at an affordable
cost.Also,just looking at initial cost can sometime be deceiving as life cycle
costs should be accounted for that includes maintenance costs and efficiency of
labor in using the press brake.Hydraulic press brakes began replacing
mechanical ones in the '70s due to costs and safety issues.Mechanical
components were replaced with a hydraulic system which eliminated these costly
machined parts.Of course, incorporating a superior hydraulic system with
quality components is paramount to supplying reliable and accurate equipment
for the end user.The shearing machine
buyer should also ask if valves,rings,seals and other key hydraulic components
are readily available and if the company they are buying from has a good after
sales service staff.Proprietary parts are often difficult to find or can take a
while to obtain.Press brakes,like all machines,have features that differ across
the various manufacturers. The back gauge is a feature that is generally not
included with this machine as standard equipment even though it is extremely
useful.This gauge is typically sold as an option.This is true also for tooling
as well.There are specialty tooling companies that sell after market press
brake tooling for all types of press brake jobs.Yet,a savvy buyer will be able
to negotiate a front operated power back gauge and tooling package to be
included with their press brake press brake
purchase.If the supplier is on the cutting edge he will have either American or
European style tooling to offer to the customer.Since the buyer usually has to
rely on the salesman's recommendations,it is very important to buy from a
dealer who not only is knowledgeable about metal fabricating machinery, but
also has some metallurgical background and common sense.When the customer says
they want a 150 ton press brake for instance,the salesman needs to query them
further and pin point the type of material they are going to be working
with.Bending stainless steel requires 50% more power than bending 60,000
tensile plate for instance.The salesman should know that the term "mild
steel" hasn't existed in over 20 years.This material was replaced with A36
and the tensile can range from 57,000 snuff
bottle psi up to 80,000 psi.There is a huge gap,so instead of figuring 15.4
tons per foot when bending ?" A36 material you need to kick it up to at least
19 tons per foot.Even though the end user may not have given enough information
to the sales person,it is still up to the sales person to help match up the
right equipment for the job by asking the right additional questions.The buyer
also needs to be certain that whichever press brake they purchases that it is
flush floor mounted.Many of the 150 and 176 ton machines on the market require
a slot in the floor to accommodate the apron that hangs from the front end of
the press brake.Sometimes the photo in a catalogue does not pick up this
issue.Ask cheap soccer cleat your
sales person so that you don't become surprised and pay a lot more money for
this type of foundation.Purchasing press brakes is an important task;there are
some valuable tips that can go a long way in saving the buyer money and labor.
