Operator Safety Protection
Use of protective equipment
Be sure to wear personal protective gear including goggles, masks, gloves, and
earmuffs. Wear clothing with long sleeves or other clothing that does not expose
the skin, and fasten the cuffs and hems tightly.
Attention to the work area
Install an enclosure so that persons other than the operator do not enter the
work area, and ensure that all persons, if any, in the work area are wearing
protective equipment.
Keep the floor of the work area clean at all times to prevent the risk of slipping
or tripping on dust, cutting particles, oil, water, or other substance.
There is the risk of fire caused by heating, sparks, or other factor resulting from
use of the product. Do not use the product close to a flammable liquid or in an
explosive atmosphere.
Also be sure to enact fire prevention measures.
Precaution regarding cutting particles
Fragments, cutting particles, and other substances generated during work will be
scattered into the surrounding area. Be sure to use a dust collector or othermeans
to collect them.
Be sure to observe the methods described in this manual.
Using the product in ways inconsistent with the methods described in this manual may result in serious injury or death.
Ensure there are no loose screws before use.
Installation onto a machining center or other machine
WARNING: When chucking, slide the shank onto the chuck of
the machining equipment securely all the way to the base.
If not inserted all the way to the base when chucked, vibration during
machining may cause this product to fall from the machining equipment.
There is the risk that this may cause operator loss of sight or injury.
When installing, use a chuck that is correct for the shank diameter.
Install and use on machining equipment that can control the rotational speed.
Do not use through-spindle coolant. If coolant gets inside the holder, the
floating function may not work properly.
When using on a horizontal machining center, the floating function may not work if
the spring load is low. Make sure you perform an operational check before use.
You cannot use the product on machining paths with intermittent sections where the
XEBEC Brush Surface may fall or where there are protrusions where the floating function
cannot work.
When the product is used with precision machining equipment, there is the risk
that cutting particles may have an adverse effect on the equipment sliding parts.
Be sure to properly collect cutting particles and wash thoroughly.
When wet machining
Do not aim coolant directly at the floating holder. If dust or coolant gets into the
holder, the floating function may not work properly.
When dry machining
Use a dust collector to collect the dust that is generated by machining. If dust gets
into the holder, the floating function may not work properly.

SAFETY PRECAUTIONS
Pre-Work Check
Perform test operation for 1 minute or more before starting work, and for 3
minutes or more after the machine tool or product was changed, and check that
there is no looseness, vibration, or other abnormality of the machine and the part
where the product is installed.
Precautions for Use
Read this instruction manual before using this product. Failure to do so can result in serious injury or death. This instruction manual must be
kept in the vicinity of the machine at all times so that it is accessible to the operator.
There is the risk of operator loss of sight or injury resulting from
this product detaching from the machining equipments, bristles
breaking off, workpieces breaking, etc.
Fragments, cutting particles, burrs, etc., occur due to
processing with this product, and these can pierce the eyes or
skin of operators causing loss of sight and injury.
Dust occurring as a result of processing with this product can
cause lung damage, irritate skin, and bring on allergic reactions.
Even if there is no problem at the pre-work check, if vibration or
other abnormality occurs during use, discontinue use
immediately. Continuing to use the product when there is an
abnormality presents the risk of operator loss of sight or injury
resulting from this product detaching from the machining
equipments, bristles breaking off, workpieces breaking, etc.
Do not use the product while exceeding the maximum
rotational speed, depth of cut, or brush projection, as there is
the risk of operator loss of sight or injury resulting from this
product detaching from the machining equipment, bristles
breaking off, workpieces breaking, etc.
Use the XEBEC Brush Surface suitable to the applicable brush
diameter, and use the bush matching the shank diameter of the
XEBEC Brush Surface. There is the risk of operator loss of sight
or injury resulting from this product detaching from the
machining equipment, parts breaking, etc., if a tool or bush not
suitable to the appropriate shank diameter is used.
When chucking, slide the sleeve shank of the XEBEC Brush
Surface all the way to the end of the tool holding tube of this
product or bush (the sleeve flange end should directly
contact the end of the tool holding tube or the bush). Using
the product in ways inconsistent with the methods described
in this manual presents a risk of operator loss of sight or
injury resulting from this product detaching from the
machining equipment, parts breaking, etc.
Do not press the floating function in further than the permissible
operating range (6 mm). Using the product in a way that is not
consistent with the methods of this manual presents a risk of
operator loss of sight or injury resulting from this product
detaching from the machining equipment, parts breaking, etc.
The built-in spring makes the tool holding tube float, and this allows stable processing via
load control with the machine tool.
It can be used on machining centers, NC lathes, drilling machines, special machines, and
other machine tools.
It is possible to change the cutting load according to the processing quality required.
Edge quality stabilized by offsetting changes in the cutting amount caused by tool wear.
Reduces frequency of adjustments required to compensate for changes to depth of cut and bristle length.
Reduces tool wear by stabilizing processing conditions.

This product is an optional tool designed exclusively for
XEBEC Brush Surface. (FH-ST12-SL10: φ6, φ15, φ25, φ40)
Do not attach a tool other than the XEBEC Brush Surface.
Also read the XEBEC Brush Surface Instruction Manual.
WARNING
As a result of the above, there is also the risk of damage to machines, jigs, and workpieces.
