results other than specified in this manual.
■Regarding Signs
It indicates contents informing possibilities of death or
serious injury in case of incorrect handling.
It indicates contents informing possibilities of injury due
to handling error or occurrence of material damages.
This symbol indicates operations that should not be done.
This symbol indicates operation that should be done.
■Recommended Air Pressure
Pneumatic pressure in the range of 0.45 to 0.55 MPa to use.
Use beyond the range may cause malfunction.
■Recommended Facility
Check the usage environment before the installation.
Supply oil-free compressed air by using an oil mist separator or etc.
If the air contains oil, dressed chips may not be swallowed properly.
■Before Installing
Do not use pipes with different diameters or other fittings (ex.
Replacing with speed controller).
The performance may decrease if different parts are used.
Check the pipe diameter of input side.
The product is designed to use φ10 hose (outer diameter).

5. Assembly Procedure
※For CDK-R.
■Procedure
1. Remove the bolt (M5-16L x 2pcs) referring to the figure below.
2. Mount an adopter with accessory cap bolts and Washer (M4-30L x 2pcs
and M4).
※When installing the air blow unit, use the bolt attached to the air blow unit
accessory. For details, refer to the air blow unit manual.

3. Mount a chip collector with 3-point sems bolt (M4-8L x 4pcs) on the
adopter.
4. Attach hose and hose band to chip collector.
※For the hose, a standard 1(m) hose comes included. Cut it before use if it is too
long.

6. Cautions and Confirmation before the Operation
■Notes
1. Use an air hose with an outer diameter Ø10 for vacuum unit.
2. Pneumatic pressure in the range of 0.45 to 0.55 MPa to use.
Use beyond the range may cause malfunction.
3. For the hose, a standard 1-m hose comes included. Cut it before use if it is
too long.
4. If you use the hose with it bent at an acute angle, it may cause chip clogging
or hose damage, so please use it with an appropriate bend angle (100R or
more).
5. Although flame-retardant materials have been used for the hose, it will not
be able to withstand extreme heat.
6. If you use the hose with a length of more than 1m, the product may not be
able to demonstrate its proper performance due to lowering the suction
force.
7. Tightening the screws with strong force may cause damage.
Check the above notes before starting the operation.

7. How to Dispose of Chips
■Notes
Discharge the dust in dust box DB-01 before chips clog it up completely.
The chip size will vary depending on the product or the use conditions, but for a
general dress setting at φ16 (polishing at 1500 N/sec), DB-01 will be full of
chips after dressing about 1500 times (for 1500 seconds).
If you use the machine with chips still built up in DB-01 without having been
discharged, it will cause poor suction.
■Procedure
1）Remove the dust box.
2）Dispose of the chips and assemble the dust box.

8. Timing Chart
■CVC air timing chart example
Make adjustments as necessary, referring to the above.
If you are using a hose that is 1.0(m) or longer for the hose from CVC to the dust
box, adjust the CVC (SOL) suction time so that it is a fairly long time.
Gun pressure
Dresser
rotation

9. Maintenance
※The images below shows maintenance procedure for CDK-R as an example.
■Cleaning
Check chips clogging in CVC and clean it up regularly.
■Inspection
An adapter plate is designed and made thinly to keep wide acceptance for a
gun access. Check if the plate has no bent.
Check the inlet.
Check for deformation.

14
10. Troubleshooting
■Suction is poor
1. Check the air pressure.
0.45 to 0.55MPa when the vacuum unit is in operation
0.3MPa or more when operating the optional air blow unit
Please set the equipment side so that it becomes.
2. If the discharge hose is extended, it may cause performance degradation.
3. If the hose is bent at an acute angle, the product may not be able to
demonstrate its proper performance.
It may also cause a fault, so use the hose with a moderate curvature (R100 or
less).
4. Furthermore, check that chips have not built up in the chip receiving section
(DB-01).
11. Supplement
■Required specs for the solenoid valve
→One with a Cv value of 1.0 or more
■Recommended solenoid valve type
→SMC：VP342-5G1-02A
■Diameter for the hose from the solenoid valve to the CVC
→φ10 or more
■Diameter for the hose from the air source(primary side) to the solenoid valve
→φ10 or more
■Diameter for the hose from the CVC to the dust box
→φ32(inner dia.)
