Customer's request
This is an example of a customer requesting fine comb blade processing (details are as below):
-Meet groove width W0.070mm, comb blade surface dimension 0.5mmx0.5mm and depth (height) h0.8mm.
-Select appropriate cemented carbide grade equivalent to the grade originally used.
In addition to the strict dimensions requested, processing of cemented carbide was required, resulting in the customer facing difficulties in finding a vendor as only a few manufacturers could handle this. They have contacted us given our abundant processing experiences and knowledge of cemented carbide.
Machining details
Based on the grades which the customer used previously, we proposed our equivalent grade EF01, and moved on to processing.
This example involved form grinding process, but since the required accuracy was very high such as groove width W0.070 mm, comb blade surface dimensions 0.5mmx0.5mm and depth (height) h0.8 mm, it was necessary to put the following points into account:
-For high-precision fine groove processing, it was necessary to select the optimum processing machine and grindstone.
-The grindstone was required to be formed into a shape to achieve the groove processing, and must be maintain during processing .
For the processing machine, we selected the super-precision high-reciprocating forming grinding machine (Nagase Integrex SHS-20) used in-house for high-precision products.
In addition, in order to minimize the dimensional difference between the groove shape and the machining shape in the drawing, in advance, the machining shape was repeatedly checked, the grindstone was dressed, and the axis was adjusted, which gave optimization the grindstone shape and machining conditions. As a result, we were able to manufacture products with a groove width of W0.061 to 0.078mm, a comb blade surface dimensions of 0.492 to 0.510 mm, and a depth (height) of h0.791 to 0.793 mm as the customer requested.
Results of machining and service
In this case, due to extremely difficult machining, only a few manufacturers could handle this, and the customer had some difficulties in finding a vendor.
However, we were able to perform the processing as requested by the customer.
In addition to the quality of our products, we have been highly evaluated for our ability to respond in a short delivery time, and we are continuously receiving requests for processing cemented carbide.
