9. Operation
To position the support arm, loosen the upper bracket locking knobs,
Fig 9.6, move the arm into position and re-tighten the knobs. The micro
adjustment collar can be used if necessary for fine adjustment.
For best results position the guide bar so that when the trueing bar is in
contact with it the tip of the tool is parallel to the stone's surface as shown
in Fig 9.7.
Position the tip of the tool to lightly touch the stone. Lift the tip from the
stone and turn the machine on. Raise the trueing bar to touch the guide bar
as shown in Fig 9.7 and slowly move the tip from left to right across the full
width of the stone until the tip is in continuous contact, Fig 9.8.
If the stone is being trued after a period of use, then position the tip to touch
the highest point of the stone as shown in Fig 9.9.
If the tip is intermittently in contact with the stone after carrying out the
above procedure, lower the tip slightly and repeat until continuous contact
is achieved.
The stone must also be trued to be concentric to its shaft. To achieve
this, true the stone until the tip of the tool touches across the stone's full
circumference as well as its full width.
As the trueing tool is used the tip will wear. To ensure even wear across its
surface it can be rotated by loosening the securing screw as shown in Fig
9.4 with a 6 mm hex wrench, repositioning the tip and re-tightening the
screw.
Dressing the Stone
The stone's surface must be dressed for use after it has been trued.
Use the WG250/R Stone Grader to apply either a coarse or fine surface to
the stone as shown in Fig 9.10, by applying it for approximately 30 seconds
with reasonable force to the stone as it rotates.
The darker side of the stone gives a coarse finish for quickly grinding
material away from the tool, ideal for reshaping tool profiles.
The lighter side gives a fine finish, suitable for achieving a razor sharp edge
to existing tool profiles.
The stone grader can also be used to rejuvenate the stone's surface if it
becomes glazed from use.
