3. Cleaning
3.1 Preparation for cleaning
For cleaning the Lamellar Grinding Machines T-20/25 must be unplugged from the
electrical power supply (unplug from power plug).
3.2 Cleaning instructions
The Lamellar Grinding Machines T-20/25 must not be cleaned with a
high-pressure cleaner or be put into water!
The polishing honing disc must not come into contact with water.
Clean the dismantled parts of the Grinding Machines with a brush or a rag.
3.3 Get grinding machine ready-to-operate
Install the cleaned parts in reverse order.
4. Operation
4.1 Safety Instructions!
Prior to working with the Grinding machines T-20/25, the following safety instructions
must be observed:
- Focus on your work
- Do not talk to and with people
- Do not touch the grinding area
- Keep working area clean and dry / safe footing
Hold the cutting-edge of the tools always in direction of the discs, see arrow,
- For grinding and polishing always wear safety goggles!
Injuries are possible because of free-running discs. These cannot be covered due to
convex grinding.
Besides, when the machines are used carelessly, minor injuries can happen, because
of the unused but freely revolving abrasive disc on the opposite side.
ATTENTION!
Instead of the lamellar grinding disc, the polishing or honing disc, or a felt disc, no
ceramic or resin bonded abrasive discs or any tools, other than provided by us, must be
used.
The legal accident prevention regulations must be observed!

4.2 Sharpening of tools with the lamellar grinding disc
Pre-grinding (changes in shape of the cutting edge) and finest regrinding are achieved if
the tool is moved in a simple alternating motion in a longitudinal direction (somewhat
parallel to the motor axis) and by varying the grinding pressure. The lamellar disc adapts
itself automatically to the cutting edge of the tool, in way, that if required, the existing blade
shape is fully maintained. Enhanced cooling of the lamellar disc prevents tarnishing of the
tools.
IMPORTANT!
The tool cutting edge must be always held in the rotation direction of the abrasive disc. As
soon as a fine burr is formed on the cutting edge, the grinding operation has to be
terminated.
4.3 Honing of the tools
The polishing, honing or felt disc respectively, fixed at the left side of the machine is used
for honing. Only this way the tools get their fine, burr-free cutting edge.
IMPORTANT!!
Hold the cutting edge always in rotation direction of the disc.
The cutting tools have to be cleaned after grinding and honing!
5. Maintenance/Exchange of wearing parts
5.1 Maintenance
Apart from cleaning at times, the machine does not need any greasing or maintenance.
The ball-bearings are sufficiently supplied with fat lasting for several years.
5.2 To assemble and/or disassemble the lamellar grinding disc, the polishing and
honing disc
- Disengage the Hexagonal Nut SW 22
- Remove the polishing-honing disc, the lamellar grinding disc respectively and the
- safety washer from the grinding shaft.
