How many blade sets can I do before the disc needs refinishing?
We have found 500 to 1000 A5 blades to be the average on manual usage. Speed
of stroking, pressure, freshness of grit charge, and the changing of grit
size have a big influence on disc life. We do not yet have an average for
the automatic.
Sharpeners that remove .0005" per blade as opposed to sharpeners that
remove .0015" per blade will do more blade sets since they are honing
for less time per blade set. Disc wear is relative to how much time has been
spent grinding. Although counting blades determines how many sets have been
sharpened on a disc surface, it does not determine if the surface is true
or not. In order to produce well sharpened blades at all times, a disc needs
to be refinished before it is out of tolerance. Monitoring the grind on each
blade by the use of a rubbing block is the best way to know when your disc
needs refinished.
What is a test, or rubbing block and what is its purpose
?
A test/rubbing block is a precision ground cast iron plate that you rub a
blade on to determine the contact pattern of the ground surface. This burnishes
the high areas of the surface and reveals whether or not the blade was ground
correctly to insure even tooth contact for optimal cutting and blade life.
This monitors the technique of the operator and also the condition of the
disc surface. The only reason for not using a rubbing block to check your
grind pattern is that you do not want to know what it is. Visual inspection
without the use of a rubbing block does not indicate one of the two most important
factors in clipper blade sharpening - tooth contact pattern.
How many blade sets can I do per charge?
The length of time honing per set and the size of the blades will determine
the number of sets you can sharpen before excessive down pressure is needed
to effectively hone. We recommend approximately 2 minutes of honing time per
charge when sharpening A5 blades.
How long does it take to sharpen a blade?
Using 240 grit, 20 seconds removes approximately .001". Depending on
the blade, this may or may not be enough to make it completely sharp.
Will I get the proper hollow grind on the 14" diameter
disc?
Yes. There is a misconception by many people that disc diameter and grinding
speed play the determining factors in the hollow grind and sharpness of blades.
We have proven results that show that better than factory results can be achieved
on discs of any diameter clear down to 6" if the proper angle is machined
into the plate and then the surface scraped for accuracy. Any amount of hollow
grind can be achieved no matter the disc diameter. It is the angle that it
is machined to that determines the amount of 'hollow' it will grind into a
blade. Keep in mind that the disc profile is somewhat irrelevant unless it
is accurately transferred to the blade by using proper sharpening techniques.
Does the lid make the operation of the machine dust free?
It effectively contains the grit within the housing. Air borne grit is drastically
reduced as compared to a machine with no lid. The optional dust control blower
and filter makes the machine practically dust free.
Do you offer training seminars on your system?
Two hours of instruction are included with the purchase of our system. We
also include detailed printed instructions and a video with each machine that
lead you step by step through the sharpening process with our system. We are
also available for phone consultation for any questions, or problems you may
be having.
