Cost savings with a CNC bridge saw

Many fabricators look at purchasing a CNC saw with concern and that's fair.  A 5 axis CNC saw can easily costs 2 to 3 times more than a regular manual saw.  It's far more technologically advanced and allows for much more cutting detail and programming so that's part of the cost differential. However, when you look at all the factors that are involved, it's a guarantee that you'll be saving money from day one. Let's take a look at the reality of these elements.  

 

To use some numbers as an example, let's say your company does $2 million per year in overall revenues.

Look at your approximate material costs =  $600,000

Labor costs 30 - 40% = $600,000

Gross Profit = $800,000 without a CNC saw!

Savings #1) Slab Efficiency

Using a CNC saw or a Saw-Jet will produce increase yield

of 10% to 20% on your slabs.  This produces additional

revenue/savings of $60,000 per year.

Net profit = $800,000

          +         $60,000

                   $860,000

Savings #2) Cutting efficiency

A CNC saw is able to take a laser template or other DXF fileof your countertop, input it into your saw programming, receiveany adjustments or details you need, and than cut it entirely without human assistance or oversight safely behind the stainless steel walls.  It functions fully automatic, needs no encouragement, never takes brakes, never gets sick, never asks for more money, it just works until the cutting is done.  While it's cutting your fabricator can, instead of manually cuttingwith a regular bridge saw, do other things like polishing, grinding, or whatever else needs to be done.  This freeing up of his time while the saw is working results in savings, financial savings to you.  Figure 1 - 2 hours of gained time because the saw needs no attention.  

$30 - $45 per hour saved, let's use $37 x 2 hours = $74 per slab Figuring a fabricator at this level is doing 25 kitchens per week.  So presuming 1.1 slabs per kitchen = 30 slabs per week

30 x $74 per slab savings - $2,200 per week x 48 weeks = $106,560 per year savings

Net profit = $860,000

                 + 106,560

                  $966,560

Savings #3) Sink and faucet shaping & cutting

A CNC saw with a finger bit spindle can process sink holes

and faucet holes quickly and efficiently.  This is a savings

of at least 1 - 2 hours per kitchen fabrication job.  Using the

numbers above, figuring that an employee can do other

things while the CNC saw is cutting out sinks and faucet

holes, results in yet more savings.  

25 kitchen per week, x 1.5 hours saved = 37.5 hours saved per week 

37.5 hours x 48 weeks = 2,700 hours saved x $37per hour = $99,900

Net Profit =   $966,560

                      + 99,900

               = $1,066,460

Savings #4) Polish and finish slabs

Savings #5 Installation speed and accuracy

 

It's well known that having a CNC cut your kitchen from

a laser or highly accurate templating system results in

faster installations because everything fits well, tight, and

is lined up from the start.  You can figure saving

approximately $100 per installation just in time savings.  

Speed of fitment, less cutting and grinding on site, better

fit and finish in less time. 

$100 per installation x 25 kitchens per week = $2,500 per week x 48 weeks = $120,000 per year savings.

Net Profit.   $1,066,460

                   + $120,000

                   $1,186,460 

So, your numbers may be different but do the math using this calculation.  A one year savings of nearly $1.2 million in this reasonable example is a massive difference.  Of course, this is just an estimation and you'll have to use your own numbers but we think you'll see that purchasing a CNC machine is more than a good investment, it's a business necessity and a huge boost to your bottom line profits.
