Auger drill bits carbide plates: Dimension of our products
OEM is also available, we can also produce according customer’s drawing
Auger drill bits carbide plates:Production Flow
1.Soon after the order is confirmed, carbide cross drill bit products will start to prepare the RTP powder as per customer’s requirement with our wet-grinding machine
2.Before mass production, we need to do a trial pressing and sintering using every mould, and we check the appearances and the sizes of carbide cross drill bit samples with micrometer, projectors etc. to ensure that the requirements of the drawings can be met before batch production
3.Bulk production ,press the raw materials to shape blanks,and all carbide cross drill bit blanks must be passed by semi finished inspection,
4.Then sinter blanks to finish (HIP) and finished products inspection, we have 10 sets of vacuum sintering furnace and 2 sets of HIP in the factory ensure the best quality and production capacity.
5.
1). cleaning/tumbling is to make the carbide cross drill bit look more beautiful.
2).The carbide cross drill bit can be ground according to customers’ order to a tolerance of +/-0.05
