4. Features and accessories
Features:
•Both main shafts have been specially deisinged and the precision bearing is used to fit the main shafts
which are made of alloy steel heat -thrated for high wear resistance, precision, as well as
maintaining to the lowest temperature for durability and stability.
•The motor base and the spindle bushing are adjustable.
•The motor is well designed with a special and nice appearance. The RPM of this motor varies
depending on the size of the work piece.
•This grinder is capable of grinding a work piece to a minimum of 3mm in outer diameter and from
2mm up in inner diameter (bore) with a accuracy within 0.003mm and a well finished surface.
(supplied with special attachements)
•The spindel bushing is made of cast iron and supported by three surfaces. Therefore, it si durable and
elastic.

5.3 A djust the centre height
Adjust the centre height equal to the centre of the lathe. Then loosen bolt (B) half a turn with a
hexagon wrench. Then use a Allen key at dial (A) and turn it clockwise or anti clockwise to adjust the
height to line-up both centres (0.125 mm for each mark of dial A), then tighten bolt (B) to fasten the
tool post grinders position.
fig. 3
5.4 A djust belt tension
Adjust the V-belt tension each time the tool grinder is installed to ensure a safe and accurate use of
the tool post grinder. To do so, loosen both bolts (C) a bit, then use handwheel (B) to adjust the V-
belt tension. A correct tension is, that you can either push the V-belt for roughly 10mm in the middle
of the two pulleys.

5.5 D ressing the grinding stone
To dress a grinding stone, use a diamond dressing tool that can be clamped into the chuck (position E)
of the lathe. Then move the tool post grinders stone close to the diamond tool and switch on the tool
post grinder. Then move the stone towards the diamond tool until it touches the stone. Move the tool
post grinder longitudinal along the diamond dressing tool a few time. Then move the tool post grinder
inwards but no more than 0.03mm and repeat the longitudinal movement. Repeat these action until
the diamond dressing tool touches the whole surface of the stone.

6. E lectrical connection
The tool post grinder is supplied with a connection cable and on/off switch at the motor. Meaning the tool
post grinder can operate as a standalone apparatus. However, it is recommend the tool post grinder
connected to the lathe controls in order to have an interface in terms of safety.

damaging of the tool post grinder and lathe, but most of all personal injuries.
7. E xtra Information
Bear in mind that this tool post grinder is an accessory for lathes and depending on how it is
connected to a power source, it has its risks regarding stopping. As mentioned earlier, it is our
recommendation to have the tool post grinder connected with a good interface with your lathe.
Using the tool post grinder, always be aware to follow the correct working method. Meaning, never
to touch workpiece and grinding stone with each other when either one isn’t rotating. Always,
grind in little steps, never use rapid traverse when both workpiece and grinder are close to each
other. Follow the correct procedures according chapter (5) and never misuse or alter the tool post
grinder other than what it is intended for.
