Yokota Corporation

We design and manufacture inspection machines and FA equipment, and offer precision part machining.

The pillars of our business are the machine department (industrial machinery design and manufacturing), and the precision machining department (mainly bearing turning). The machine department makes automation proposals for various fields, such as auto parts, electronic appliances, and OA equipment. This department has accumulated technological strength through industrial machinery design and manufacturing (e.g., inspection machines, assembly machines). They developed an automated urinalysis system using our color analysis technology, as well as an arm blood vessel detector, using control technology with LEDs. A joint project is currently underway with Tokushima University to develop an inspection technology using light.

Inside diameter inspection equipment “FLAT VIEW”
This equipment is used to perform non-destructive and non-contact inspection for inside diameters of bearing-shaped works.
We offer quicker and more reasonable equipment configurations compared to conventional inspection methods by using the technology we developed together with Tokushima University.
We offer inspection of portions that are difficult to inspect by visual inspection. Please use our free sample testing services.

[Company strength]
There are two pillars to our business. One is the machine department, which designs and manufactures mainly auto parts assembly and inspection machines. The other is the precision machining department, which provides turning processing for bearings. The machine department has developed many automated machines for domestic Japanese and overseas customers, with customization according to their needs. The department staff members include 12 first-class technicians and 10 second-class technicians. This department has advanced technological strength, and has also focused on industry-university collaboration with Tokushima University. Their strength lies in the fact that they can discover detailed needs on the manufacturing floor by making use of their own productivity improvement activities for the precision machining department. The precision machining department maintains speed and quality in production, and produces 7 million sets of single ball bearings per month. This is one of the largest quantities in Japan. This department has continuously implemented QC activities for 33 years, and has focused on developing human resources. It possesses 280 units of single-function machines, 40 units of NC lathes, and 3 units of cold gear rolling machines to manufacture both mass-production products and difficult-to-machine products. 

[Business description]
Machine department: Our machine department makes automation proposals in various fields, including auto parts, electric products, and OA equipment. The department is trying to cultivate new fields by obtaining licenses for medical device manufacturing and sales as well as other efforts. 
Precision machining department: Our company has been turning single ball bearings and various other bearings, auto parts, and machining tools since our establishment in 1960. 
Other: We have 8 second-hand stores and 1 home center, mainly in Tokushima Prefecture. 

FA equipment design and manufacturing; precision part machining

[Strength of products/technologies]
The FA equipment developed by our machine department has already been adopted by major parts manufacturers for use in their domestic Japanese and overseas plants. The department can handle all processes from design and manufacturing to assembly and electric control for various kinds of auto part assembly, inspection, and machining equipment. Their main focus is on inspection equipment, such as devices for scratches, cracks, and incorrect embossing. The precision machining department makes use of cold rolling and other technologies. They provide customized turning processes in order to meet the increasing need for high-mix low-volume production, and cost reduction for mass-produced products.
