Tungsten Carbide Cutting Tools for Deep Hole Drilling

Details: Category: Tungsten Information; Published on Tuesday, 02 June 2015 13:26; Written by lucy; Hits: 424

The deep hole drilling processes are separated by the ways cutting coolant removes heat and flushes the chips. Generally ,While using tungsten carbide cutting tools, the deep drilling types are fallen into three categories,

Gun Drilling

The tungsten carbide cutting tool is a fluted solid rod uses carbide tips and recognized as a straight fluted drill with ability to offer the coolant entry and chip removal. Coolant is injected through the center hole, when it flows back outside the drill, the chips and the heat are removed.

Boring and Trepanning Association

The tungsten carbide cutting tool is a tube. Coolant enters around the cutting tool surface and removes the chips out through the center tube. The acceptable minimum sizes of diameter is over15.6mm ,since the technology limitation.BTA drilling becomes more effective than gun drilling around a 50mm hole diameter.

Ejector System

The cutting tool is a set with two nested tubes.Coolant is carried through the smaller tube to the cutting face and the cutting chips are removed via bigger tube.

Tool Holder Selection

The recommended types of tool holder for the tungsten carbide cutting tools comprise collet chuck, side handle and hydraulic chuck. On the contrary, quickly change chuck is not suggested.

Proper Cooling Process

In order to ensure the tungsten carbide drill bits could work functionally, special attention needed to be paid to the directional combination of cooling as well as the upper and lower echelon configuration during the external cooling. In terms of inner cooling, the pressure and flow rate are the vital parts. Attention also needed to be draw for the leakage of the cooling liquid.

Beside all the aspects listed above, the right drilling technology also play an important role in the selection procedure.

4.The tungsten carbide cutting tools must be away from corrosive atmospheric and properly stored in a dry environment after use.

5.When using tungsten carbide cutting tools some cutting chips might be generated, for safety consideration, the labor protection articles and use instruction are required.

6.Cutting fluid is recommended, since its related to the tungsten carbide cutting tool lifetime , to an extend.

7.If the cracks occurred during cutting process, stop using the cutting tools.

8.Let the specialists grind the tungsten carbide cutting tools, when there’s an edge passivation or strength reduction .

As one of the most popular solid carbide cutting tools , tungsten carbide drill bits are widely used in various machining processes.Understanding how to correctly use the drill bits could improve the efficiency of the working process and also making all the material resources into good account. The aspects related to correctly use tungsten carbide drill bits include,

Right Machine Tool Selection

High power and good rigidity are the characteristics of machine tools suggested to be contained. The low power and poor precision ones like radial drill and universal milling machine should not be in the list of machine tools selection,as they may easily cause the tungsten carbide drill bits deformation and breakage.

Tungsten Carbide Cutting Tools Recycling

Details: Category: Tungsten Information; Published on Monday, 01 June 2015 18:51; Written by lucy; Hits: 394

Each year, the worldwide tungsten carbide industry generates large amount of scrap because of the parts rejected at different stages of the manufacturing and worn-out or broken tungsten carbide cutting tools.

Differently from basic recycling approach of scrap pieces, instead of breaking them into powders, the chemical approach (Zinc recovery process, electrolytic recovery and etc.) could solve some problems including avoiding the recycling equipment wear. But the there is still a considerable shortcoming related to the recycling rate of WC-Co, which is less than 20%. The improved method in nowadays is using molten-zinc (Zn) bath to recovery WC and Co from the hard cutting-tool scraps.
