Tungsten Carbide Indexable Cutting Tool’s Productivity Advantages

Details: Category: Tungsten Information; Published on Tuesday, 11 November 2014 16:52; Written by xjq; Hits: 493

Tungsten carbide indexable cutting tool is popular with many cutter users mainly due to its advantage in productivity. Using tungsten carbide indexable cutting tools to replace solid tungsten carbide cutting tool can greatly shorten cutting edge replacing time, and thus optimize the machining time. For instance, it would take about 30 minutes to replace solid tungsten carbide drill bits, while it would take only 1～2 minutes to replace drill tip before restarting machining if an indexable drill bit is used.

The shortening of the cycling time of machining is another reason why tungsten carbide indexable cutting tool can improve productivity. Using tungsten carbide cutting tool to replace solid tungsten carbide cutting tool can significantly reduce the cycling time of machining. For instance, if using solid tungsten carbide cutting tool during machining, the most of the rough machining should be done when workpieces are relatively soft, and then these workpieces should be sent to take heat treatment and be clamped again. After that, a tungsten carbide end mill is needed to do the finish machining. However, all these can be accomplished in the same tungsten carbide indexable cutting tool.

Tungsten Carbide Indexable End Mill’s Cost Advantage

Details: Category: Tungsten Information; Published on Tuesday, 11 November 2014 16:50; Written by xjq; Hits: 498

Tungsten carbide indexable end mill is suitable for milling shallow grooves, step surface, and boring blind holes. Tungsten carbide indexable end mill has many advantages in cost saving:

Firstly, it can reduce the cutting tool replacement cost. Cobalt high speed steel and solid tungsten carbide are relatively more expensive. When they break, the whole cutting tool should be replaced with a new one. Instead, in tungsten carbide indexable end mill, an indexable insert is worth just a few dollars.

In addition, tungsten carbide indexable end mill do not need to be reground, which is a labor-intensive and costly work. Also, regrinding may cause damages in cutting tool diameter size. During slotting machining, that would mean extra cost of a finish machining to meet the size requirements.

What is more, tungsten carbide indexable end mill has wide universality which helps reduce the cost. In many cases, it can be used in different kinds of workpiece materials and machining just by replacing the blade materials and groove shapes in the same cutter body.

Tungsten Carbide Indexable Turning Tool Eccentric Clamping Introduction

Details: Category: Tungsten Information; Published on Tuesday, 11 November 2014 16:46; Written by xjq; Hits: 570

Eccentric clamping structure of tungsten carbide indexable turning tools has gained increasingly wide applications due to its advantages of simple structure, convenient and reliable clamping and so on.

In the eccentric clamping structure of tungsten carbide indexable turning tool, blade is clamped to toolbar by using an eccentric pin on the upper screw. This structure is convenient to operate but can not perform bilateral positioning.

When the eccentricity is too small, it requires higher blade precision, but when the eccentricity is too large, the blade may be easily loosened under the impact of cutting force. Therefore, the eccentric clamping structure of tungsten carbide indexable turning tools is more suitable for continuous smooth cutting.

Tungsten Carbide Indexable Turning Tool Lever-type Clamping Introduction

Details: Category: Tungsten Information; Published on Tuesday, 11 November 2014 16:48; Written by xjq; Hits: 515

The lever-type clamping structure of tungsten carbide indexable turning tools is the most commonly used clamping structure at home and abroad, in which the blade is clamped to the toolbar according to lever principle. When the operator turns the screw, the clamping force will be produced through the lever, and then the blade will be located in the cutter groove side. When the operator removes the screw, the blade will be loosened, and the semicircular cylinder-shaped leaf spring can keep the shim position still. In this structure, due to the leverage, the blade can get acting force in horizontal direction during clamping, which can press one side of the blade onto the side of cutter groove. Through this, the blade can be tightly clamped.

The characteristics of lever-type clamping structure of tungsten carbide indexable turning tools: high location precision, firm clamping, reasonable stress, convenient in use, poor manufacturability. It is more suitable for mass production.

Tungsten Carbide Indexable Turning Tool Introduction

Details: Category: Tungsten Information; Published on Tuesday, 11 November 2014 16:44; Written by xjq; Hits: 532

Tungsten carbide indexable turning tool, with three or more indexable cutting edges, is formed by clamping the tungsten carbide indexable insert to the toolbar using mechanical method. It is composed of toolbar, blade, shim, and clamping structure. When one of its cutting edges wears, operators can loosen the clamping structure, switch to another cutting edge, and clamp it again. When the cutting edges all wear off, the indexable insert then can be replaced by another one of the same kind. It can avoid the defects after welding in welded turning tools. Therefore, tungsten carbide indexable turning tools can allow full play to the original cutting properties of blade materials and thus help extend the tool life. Tungsten carbide indexable turning tool has three main clamping structures: eccentric clamping structure, lever-type clamping structure and wedge-type clamping structure.

Tungsten carbide indexable turning tool is a kind of advanced cutting tool, because it do not need to be reground and its blade can be easily replaced, which help greatly reduce the regrinding cost and improve cutting efficiency.
