Toothed wheel bits have been widely used as a tool for drilling rock formations, and the significant improvement in bit performance has directly reduced drilling costs, especially in the last decade, when the progress has been the fastest. It consists of more than twenty kinds of components such as cutting structure, bearing structure, locking element, oil storage and sealing device, nozzle device, etc. The tooth wheel is a cone with (or milled out) teeth on it.
Customers are currently using imported tools to process the ball groove and locking groove of the tooth wheel, the unit cost of the workpiece is too high, and we hope that we can help them to solve the problem.
The scene using R1.5 and R2 groove cutter finishing wheel ball groove and locking groove, the difficulty for the insert is that the workpiece material is hard, the surface roughness requirements are high and can not have a wave pattern and small steps, finishing allowance is large, the machine tool clamping rigidity is not enough, the processing is easy to produce vibration; tool toughness should be good, processing can not be a small chipping, or it will result in the production of the workpiece steps.
These issues on the performance of CBN tool material and the edge of the treatment is very high.
WSS choose medium content CBN, using its good toughness, edge using negative chamfering super-finishing grinding programme, to achieve the customer's requirements on the surface quality of the workpiece, according to the customer's on-site machining parameters for the test, the tool machining effect is stable, and the effect of imported cutting tools currently in use is the same, but it greatly reduces the customer's production costs, and solves the customer's need to reduce costs.
