When the tungsten carbide reamer’s diameter size has increased or the error is large, there are the following solutions:

1.Being appropriate to reduce the outer diameter of the reamer according to the circumstances ;

2. Having appropriate adjustments to reduce the amount of feed or allowance;

3.Straightening or bending can not be scrapped reamer;  

4.Choosing a better cooling performance cutting fluid;

5.Adjusting or replacing the spindle bearings.

The tungsten carbide reamer will have problem with diameter size in working, the circumstances are the followings:

1.Tungsten carbide reamer hinged blade’s diameter size design value is too large or has the mouth burr;

2.Cutting speed is too high, feed allowance IS inappropriate or excessive;

3.Tungsten carbide reamer main angle is too large;

4.Tungsten carbide blade hinge on chips adhered mouth tumor;

5.when sharpening the blade opening swing hinge poor tolerance;

6.when installing carbide reamer taper shank surface oil is not clean or cone has bump hurt;

7.shaft bending or spindle bearings is too loose or damaged.

Tungsten carbide cutting tools with one or more hinge cutter for removal of the hole of the machined surface of the thin metal layer rotary cutter. After processing through the hole cutter can obtain precise size and shape.
Tungsten carbide reamer for reaming the hole after processing has been drilling (or reaming) on the workpiece, is to increase the precision of the hole, reducing the surface roughness of the hole is used for finishing and semi-finishing processing tool , allowance is generally small.
Tungsten carbide for machining cylindrical bore reamer more common. For machining a tapered bore is tapered reamer reamer, relatively less. The tungsten carbide reamer is mainly used to process high difficult hardness materials.
Judging by the use with a hand reamer and machine reamers, machine reamers can be divided into straight shank reamers and taper shank reamer. The hand is the straight shank type.

Stainless steel weights come in bullet and egg shapes and an assortment of weights. A real advantage of steel over lead for fishing sinkers: Steel sinkers retain their shape and last longer, while lead is malleable and deforms easily. Stainless steel is often combined with ceramic material in fishing weights. 

Tungsten alloy fishing sinker is easier to feel changes in the bottom e.g. gravel to clay or mud, or vice versa...When fishing rocks tungsten also deflects much easier and recoils so hang ups aren't so frequent. What happens with conventional lead weights is that when fishing rocks it tends to take and change shape as it bends and scratches, it takes shape and get's stuck in cracks and rock cavity.

 A real advantage of tungsten alloy fishing sinker over stainless steel fishing sinker: tungsten alloy fishing sinkers retain their shape and last longer, while stainless steel fishing sinker is malleable and deforms easily.

The big consideration that most people will be making when considering how much to spend on darts is what is their goal?
 

50-70% tungsten dart will usually cost less than $40 and will be sold at larger chain stores and sporting goods stores. You really have to watch out for cheaper, mass produced imports in this category.  These will be very common, but not the best darts for the long haul.

80% tungsten dart will usually cost $20-$50 and would be considered these the most common darts sold to league players. Many of the players in our lower conferences (newer, inexperienced, shooters) use these darts.

90% tungsten dart will usually cost $50-$100. These darts are most common with guys in the league. They have worked on their game some and have slipped into a pretty consistent way of shooting. There are numerous manufacturers to choose from with a wide variety of models, this is where an individuals feel will come into play. You really need to pick a few of these up and see what is the most comfortable for you.

95-98% tungsten dart will usually cost more than $100 to purchase, not running more than $200 on a consistent basis. These darts will be extremely thin and if you have real potential for developing your game into an elite shooter，it will suitable for you.

Natural granite fishing weights are a good choice because they look like a natural part of the environment. The natural stone weights are smaller than comparable lead weights because they absorb water and get heavier.

Since tungsten alloy fishing sinker introduction to the fishing market, anglers everywhere have found Tungsten weights to be a far superior product to their lead-based predecessors. Tungsten's higher density allows these sinkers to outperform lead sinkers twice their size. Furthermore, tungsten has low bioavailability and does not pose a pollution risk.

So as for density, tungsten alloy fishing sinker is outweigh granite fishing sinker.

Tungsten carbide CNC tool can be divided into conventional tools and modular tooling two categories. The modular tool is the developmental direction. The main advantage of developmental modular tool are the followings:

1.Reducing tool change downtime, increase production and processing time;

2.Accelerating tool change and setup time, improve the economy of small batch production;

3.Improving standardization and rationalization of the tool;

4.Promoting the management and flexible processing tool level;

5.Expanding the utilization of the tool, give full play to the performance of the tool;

6.Effectively eliminating work disruptions measurement tool, can be preset outside the line.

In fact, due to the development module of the tool, tungsten carbide CNC tool has formed a three systems, namely turning tool systems, drilling and boring and milling tool system tool system.
