1. Safety
The KOMET JEL® JSF synchro tapping chuck is not only characterised by its outstanding technical features,
but also by its easy handling and maintenance free properties.
Please note to the following points in order to ensure correct application.
1.1 Explanation of Symbols
If this symbol is used, disregard of our instructions can lead to danger to people and property.
1.2 Area of Application
KOMET JEL® JSF synchro tapping chuck are suitable for tool clamping.
The product may only be used within the given technical limits. This includes the conditions set
down by the manufacturer for installation, operation, assembly, maintenance and working envi-
ronment. Usage above and beyond these conditions is considered as not correct for purpose. The
manufacturer will not give any guarantee on such usage.
1.3 Safety Advice
1.3.1 The following technical limits must not be exceeded. (see table below).
1.3.2 For rotation applications, a protective cover according to EC Machinery Directive 2006/42/
EG must be used.
1.3.3 Tool clamping and installation of the KOMET JEL® JSF synchro tapping chuck in a machine may only
be carried out by technically trained staff who have familiarised themselves with the operating instructions.
Basic rules:
a. Wear gloves when changing tools to avoid injury.
b. When releasing the tool, hold it tightly to prevent it falling and damaging both the tool and workpiece.
c. Do not exceed the max. tool dimensions.
d. Maximum cutting speed and feed values exist for every application. Do not exceed these values.
2. Warranty
The warranty period is 12 months from delivery date, if used correctly and in adherence to the operating
and maintenance instructions (see point 6).
3. Installation
3.1 Clean chuck with a cloth in order to remove oil. Important: Do not use aggressive solvents. Only use
lint-free cloths.
3.2 The tapping tool is held by means of a collet with square drive (according DIN 6499 B).
3.3 Assembly of the collets and tap
To prevent soiling of the collet, and if you are using coolant or MQL, the sealing disc must first be fitted
into the clamp nut.
4. Clamping / Releasing
4.1. The tool shank must be free of burrs and dirt.
4.2. Assembly of the collets:
Mount the collet groove on the marked position on the eccentric ring of the clamp nut. Tilt the collet in
the opposite direction until this locks audibly. Insert the tool. Screw the clamp nut with the locked collet
onto the thread of the holder.We recommend tightening the collet with a torque wrench and use the
spanner flat to hold against this (tightening torques see table under Point 1.3).
Incorrect handling will affect the concentricity of the collet and can damage
the clamp nut. Only clamp nuts with a correctly mounted collet should be in-
serted into the collet holder.
4.5 The tool must be inserted into the chuck at least to the minimum insert depth (see
table point 1.3)
4.6 Removal of the collets:
After unscrewing the holder, press the front of the collet and at the same time press
the collet out of the clamp nut by pressing the back part, opposite the marking.
5. Length Adjustment
5.1. The length adjustment is operated through the connection on the machine side,
or through the collet by means of an Allen key.
5.2. The max. torque on the adjustment screw must not exceed 4 Nm.
5.3. Please ensure that the suitable adjusting screw for the tap shank is used.
Max. length adjustment 3 mm.
5.4. Behind the length adjustment screw there is elastomer for damping. So we prevent
damage of the tap or length adjustment screw while tightening the clamping nut.
ATTENTION!
• Only use the socket wrenches provided.
• Do not move the adjusting screw when the tool is clamped.
6. Care and Maintenance
6.1. Clean regularly with a cloth. Do not use aggressive solvents and only use lint-free cloths.
6.2. Before storage, ensure that all coolant and other residue is removed and the
tools are sprayed with an anticorrosion agent.
4.3. Assembly of the sealing disc:
When inserting the sealing disc into the clamp nut, the marking on the sealing disc
must be legible from behind. Insert the sealing disc into the collet and push it forward
until it clicks. The correctly assembled sealing disc is flush with the clamping nut.
4.4 Removal of the sealing disc:
To remove the sealing disc, press on the disc from the outside until it jumps out.
It is essential to insert the tool from the front, otherwise the O-ring in the
sealing ring will be damaged. When inserting the tool, make sure that the
sealing disc is not pushed back.
