Diamond Reamers and CBN Reamers

∑||| - Our diamond reamers are used processing for precision machining parts. - |||Ζ

With over 25 years' experience providing solutions,

our diamond and borazon CBN reamers

are the most advanced of their kind in the industry. 

 

Our products have a long life, lasting two

to four times longer than regular reamers!

The quality of each individual reamer is assured because

Takezawa uses only Japan-made diamond 

and borazon CBN powder.

  

Standard products set to a regular processing hole accuracy

of H7 are available.

Takezawa can also meet even higher accuracy requests

with special made-to-order items.

 - Our Products -                                                                                 
Takezawa-Seiki reamers all perform in one round trip (one pass),

which we call single-pass honing.

 

A maximum roundness of 0.5 μm and a surface roughness

of Rz 0.5 can be attained.

 

For increased accuracy single-pass processing may be

performed multiple times with different granularity reamers.

 -  Product Features  -                                                                                 
Reamer diameter can be fine-tuned by simply turning

the end adjustment screws to increase the diameter via

the bevel's male and female tilt.

The reduction in the diameter due to the friction

of abrasive grains is compensated for by expanding

the reamer diameter so that the lifetime of abrasive grains

can be extended to its maximum limit.

 -  Efficacy  -                                                                                              
The highly valued extreme hardness of our diamond

and borazon CBN tools have four times the friction resistance

compared to regular grinding stones.

Due to the unique expansion function,

the tool life of Takezawa-Seiki reamers is up to 400%

that of ordinary reamers.

 - Variations -                                                                                               
Our standard products include four kinds

and 16 diameters of diamond and borazon CBN expansion-type

and non-expansion type reamers.

 - Our Policy -                                                                                             

Takezawa-Seiki performs process design

for optimum productivity of its customers,

designing and supplying the best reamers 

for the processes, work materials

and workpiece shape best suited to customer needs.

 - Other Products -                                                                                            

Work-time reducing machine and unique semi-automatic

honing machine envisioned for small lot-many product production.


Takezawa-Seiki has provided consultation

for the finishing process of the spool hole

for a construction machine switch bulb,

with a surface roughness of Ra 0.2,

processing length of 250 mm,

roundness of 2 μm, and cylindricity of 5 μm.

This is just one example of how our company

can handle all aspects of hole processing,

reamer and honing machine design.
