<New equipment introduction> OKAMOTO CNC ultra-precision surface grinding machine
Grinding length: 2 meters
Vibration-free thanks to linear motor drive and high-precision oil static pressure mechanism. Comes with "MAP Ken" software. High-precision polishing of curved surfaces is possible!
We are the only company in Kanagawa Prefecture that has introduced this machine. It is the No. 1 precision surface grinding machine.
< Intention/purpose of introduction>
In most cases, the lip land of the T-die is plated.
When used for a long period of time, the lip will wear and slight distortions and deformations will occur on the adjustment bolt side, which will cause variations in film thickness, especially when producing films with high film thickness precision.
Usually, to restore accuracy,
Plating removal → Lip land re-polishing → Seal surface polishing → Inlay processing → Re-plating → Finishing
This process requires a lot of time and money.
This device "controls the movement of the polishing stone in the Z direction."
It is possible (MAP Research Institute)
This allows polishing only the areas where the film-like irregularities are present.
Process: Mapping of grinding surface → Setting of grinding amount → Polishing only necessary areas → Surface finishing (hand polishing)
Even without stripping and re-plating, by using MAP grinding software to grind only the areas with defective film thickness, we can contribute to reducing lead time and costs for repairs.
CAD models
Automatic calculation of coordinate data
Automatic on-machine measurement
Automatic workpiece shape generation
The latest system brings about a revolution in grinding: "MAP grinding"
MAP polishing achieves high-precision grinding without skill/automation
When CAD data is input, the workpiece is automatically measured and the optimal grinding program is automatically generated/processed.

After mapping
Grinding necessary areas by program
STEP 1: Lip distortion is automatically measured by mapping and converted into data.
STEP 2: Specify the lip area you want to grind from the data. Specify the grinding amount numerically.
*The grinding location and grinding amount of the T-die are specified based on the customer's film thickness data.
Where our know-how is most important
STEP 3 Measure the amount of grinding and plating thickness to determine whether or not it bites into the base material.
STEP 4 Grind the necessary areas. Remeasure after grinding.
