Sub-contract calculators save on
deburring costs
A number of simple inter-active calculators have been produced to illustrate that sub-contracting deburring can be cost effective.
The Deburring Centre has commissioned a number of simple inter-active calculators to illustrate that sub contracting deburring can be cost effective Although sub-contracting deburring is not common occurrence, deburring issues are, especially when the ubiquitous rumbler doesn't work with awkward to reach burrs

Machine tool users concern with deburring grows
In spite of the widespread use of CNC machine tools, some users are not machining out loose burrs, at best they are being made smaller, but customers expect zero burrs.
Thermal deburring is consistent, reliable
The thermal deburring process is non selective - 100% of potential loose burrs are removed and computerised controlled conditions mean that every process is consistent.
Martin Bridges, Deburring Centre's marketing manager, explained: "This simple idea is based upon an Excel spreadsheet.
Clients often voice serious concerns like batch sizes, transport, economics, extra paperwork, etc, but very rarely quantify them.
I'm often using spreadsheets to work out break even and profitable scenarios.
This was seen to be a way of empowering clients of answering their own questions".
Three criteria were focused upon.
* In-house hand deburring v sub-contract automated machine deburring.
* The cost of rework v dedicated machines getting it right first time.
* And the 'old chestnut' of 'free' deburring in cycle.
The first calculator focuses on a typical component with cross holes and awkward to reach burrs.
By entering your hourly costs, time taken to deburr a single component, and batch quantity you can quickly see when farming out deburring to dedicated specialists becomes cost effective.
"Many people have commented they have been 'hooked' on the calculator," explained Bridges, "Once they've entered a set of figures, they are keen to recalculate the break even point and then the effects of bigger batch sizes or sending multiple batches.
Both gaining even more savings by amortising the set up and/or transport costs.".
