Key Devices

Our key devices allow us to offer high precision assembly and processing.

We assemble and process key devices; modules and components which are a vital part of electrical appliances. The assembly and high precision cutting in aluminum flanges of developing rollers are crucial, meaning that they need a high level of accuracy. Here at Konica Minolta Mechatronics, we provide assembly and processing with a high level of accuracy.

Aluminum Flange Cutting

We have achieved stable processing of flanges to a perpendicularity of 0.005mm and a coaxiality of 0.005mm in CNC lathes.

Blast Processing for Sleeves

Blast processing with a surface roughness of Ra 0.009mm.

Highly magnetized developing roller assembly

We have achieved in-house produced flanges with 350mm sleeves and a radial run-out accuracy of 0.014mm. Assembly and run-out scans are undertaken by automated devices which were designed and manufactured in-house to ensure product quality.

Konica Minolta Mechatronics' assembly techniques

  • ・High precision grease application techniques (0.01g) and high precision adhesion techniques (0.01g).
  • ・Requires a high precision accuracy of assembly.
  • ・Radial run-out accuracy of 0.014mm, an outer diameter allowable limit of error of less than 0.02mm.
  • ・We design, develop and introduce automated machinery to satisfy the high level of skill needed for stabilized product quality and continuous processing.
  • ・Not only stable automation, but we also construct devices which unite man and machine by utilizing human sensibilities.
