We will be exhibiting at EMO Hannover 2025.
What Is a Rolling Centers?
Can we use your products for grinding machines?
The high-precision NC70 and NCF models with (optional) V seal specs can be used.
Can we process a workpiece even with a shank other than Morse Taper shanks?
You can do so with a straight shank or any other taper shanks, if you have a gauge. We may ask you to provide a gauge.
Should we replenish grease for the bearing part?
We measure grease and apply it at the time of assembly. Accordingly, you do not need to replenish grease. If grease is applied too much, it will generate heat.
Is the bearing part of the body heated?
Heat is generated by the rotation of the bearing. The highest temperature in the normal temperature range is room temperature plus 50 degrees Celsius.
Can we process a workpiece at a tip angle other than 60, 75 and 90 degrees
You can do so. However, you need to provide a gauge, etc. in some cases.
What is the tolerance of a tip angle of 60 degrees?
It is 0 to 30 minutes.
Have you measured the precision of the outer diameter of the center shaft?
For precision measurement, we measure the center runout at the conical part of the center shaft. In some cases, the precision of the outer diameter of the
center shaft has not been measured.
Is it possible to use a high-pressure coolant for a product with a seal?
Our products are not totally waterproof. Coolant would enter the bearing part, causing corrosion. Please avoid it.
What is the hole of the model 100 with a seal?
That hole is for draining water. When setting a rolling center, please be careful so that the hole faces downward.
Is it possible to produce a product whose tip can be replaced?
We can produce it with special specs.
Can we use the work-driving center for a workpiece that has been sintered or well-tempered?
You cannot do so, because jaws do not grip a workpiece that has been hardened through sintering or the like.
Can we use it for a grinding machine?
You cannot do so, because jaws do not grip a workpiece that has been hardened through sintering. In addition, there are problems with the processing
precision and the pressing force of the tailstock.
Is the center hole necessary?
It is necessary because the processing is conducted with two centers.
Is a center shaft available?
It is not available, because respective center shafts and centers are gauging after production.
Do you produce a specially shaped product?
Please specify specs, including small diameter, large diameter, angle and shank (Morse Taper).
Is it possible to conduct detachment with a removal nut mounted on the tailstock?
BRF types are all compatible with a tailstock with a detaching nut. For the Morse taper size not listed in the catalogue, please contact us.
Do you produce a lathe center without a carbide tip?
We can receive orders for specially shaped products. Please specify dimension and specs, and contact us.
If a carbide tip is damaged or removed, is it possible to braze a new one?
No. It would cause distortion and lose precision.
Do you repair other makers’ products?
No, we don’t, because the specs of parts and tools are different.
Do you repair any kinds of your products?
Some models cannot be repaired. Please contact us.
Do you dispose of products that cannot be repaired?
If you request, we will dispose of them.
Do you supply parts, etc.?
We do not sell parts of products. We will deal with your troubles through repair.
We manufacture special-shape centers suitable for machines and workpieces.
Select from the special shape examples below and fill in the blanks with the dimensions required.
Order example : Example A N0.4 B=26 B1=10 B2=26 E=60 θ=60°
