Flow of integrated production (Ex.)
One of the strengths of Hikari Kikai Seisakusho is the excellent track record of our manufacturing machines, jigs and cutting tools, which other companies find difficult as well as turning, polishing and grinding of round products, which are technically challenging.
High-precision Quality and Short Delivery Time
The main reason that Hikari Kikai Seisakusho is chosen is our technology for polishing/grinding technically challenging products with high-precision finishing. We also accommodate a short delivery time for prototyping and implement thorough delivery control for small and medium lots as well. For an urgent project, we accommodate the shortest delivery time of 1 to 2 weeks from material procurement, cutting, heat treatment to grinding.
We Accommodate a Variety of Consultation for Prototyping, Development, etc.
Up to this day, we have been utilizing our technological expertise to accommodate many machining, polishing and grinding orders which other companies find difficult.
We have a rich track record not only of difficult-to-machine material but also of material which cannot be handled with cutting. If you have any machining including that for prototype development about which you do not know where to order or any project with technological challenges, please feel free to contact us.
We Deliver Microlevel Precision Machining with Consistent Quality
We accommodate flexibly not only on mid-size lots of approx. 500 pieces but also small lots starting with 1 piece.
Also, we deliver products with stable quality without precision fluctuation under a thorough quality control.
Taper Machining
For Morse taper shown in the left fig.
national taper, Brown & Sharpe taper, Jacobs taper, etc., we guarantee the taper fit ratio of 80% or above.
