B-Tohin Machine (Jiangsu) Co., Ltd. Factory Tour

 Production Equipment

OKUMA CNC

We introduced the complete set of advanced horizontal CNC from Japan OKUMA Co. The CNC is specially used

in the fine finishing of the cylinders and end covers of BK three-lobe roots blowers. It fulfills the processing from

semi-finished products to finished goods of high precision.

NC Machine

The NC machine of high precision, introduced from Japan, is mainly used in the processing of HC low noise

rotary blower.

Back-forth Curve Machining Planer

The problem of shapers' low precision was solved by introducing several back-forth curve machining planers.

Based on the experience accumulated in many years' co-operation with roots blower manufacturers, Nanjing

XFD Equipment Co., Ltd. developed this new type planer that is specially designed for curve machining of roots

blower rotors.

Inspection and Equipment

Various instruments

Temperature, vibration, voltage and noise measuring instruments

Test Center

B-Tohin has established its professional center covered an area of 400 square meters for inspecting the blowers'

comprehensive properties. And it also introduced the advanced CRAS signal collecting and monitoring system,

that is used to collect and send signals such as air volume, blowing pressure, noise, vibration, rotary speed,

temperature, electric current and electric voltage etc. to computer for realizing computers' on-line monitoring,

analyzing, record storing and so on. The system ranks front in the same sector.

Bearing Vibration Tester

The Bearing Vibration Tester, Model BVT-6, developed by Hangzhou Bearing Test & Research Center is a very

useful instrument for measuring and analyzing bearing vibration and noise of deep groove ball bearings, angular

contact ball bearings, cylindrical roller bearings and tapered roller bearings.
