CARBIDE INSERT QUOTATION,INDEXABLE CARBIDE INSERTS,CARBIDE INSERTS

Tungsten carbide will face with the technical innovation. In the face of tough market situation, the manufacturers of tungsten carbide cutting tools should pay more attention to the quality of product. In recent years,  the market of tungsten carbide in China is continuously expand while the quality level is still the same which Deep Hole Drilling Inserts affected the progress of the industry. The method of human hands and artificial visual of the current domestic traditional detection is inefficiency and easy to influenced by the individual factors of testers. With the mature of detection technology, intelligent automation testing equipment is attracted more attention. Automated testing is useful for improving quality and efficiency and reducing the influence of man-made factors. It can greatly improve the efficiency of detection for the product quality.

In the next few years, China's tungsten carbide product testing will face automation era. This will accelerate the optimization of China's tungsten carbide industry. As the leader of domestic custom inspection equipment provider, Beijing Leader Tech constantly feels their way into non-standard test market in recent years. It has been successfully developed a device for tungsten carbide Carbide Threading Inserts industry aimmed at the automatic test equipment of bar and cutting tools. The device can be carried out fast precision automatic quality inspection. One device can accurately measure the thickness, length, width, the lateral deformation, flat deformation parameters of the workpiece at the same time. The detection efficiency is so surprised that one second can measure 1 piece.

Toolholders for machining centers tend to work by compressing a cylinder around the shank of the tool. That is the case with either a collet holder or shrink fit. In either case, the weakness of this mechanism for toolholding is in the tool’s axial direction. Along this direction—that is, along the Z axis on a three-axis machine—the only thing restraining the tool is friction with the collet or the bore of the holder. If the Z-directed cutting force reaches a high-enough level, the tool can slide within the holder’s grip.

Technicut, the U.K.-based cutting tool supplier, routinely achieved that high cutting force in its development of an end mill engineered for aggressive cutting in titanium. Cutting forces pulling along the Z axis could cause its new tool to minutely slide within the holder, changing the gage length of the tool mid-cut. Toolholder supplier Nikken was brought in to help solve this problem, and the two companies worked together within the Advanced Manufacturing Research Centre of Sheffield, England. Stephen Eckersall, group engineering manager for Nikken, says the result of this work—the X-Treme Multi-Lock Milling Chuck—is the company’s first new product to have been researched, developed and tested in Europe prior to final design and production in Japan. 

An existing holder was the starting point of the development work. Nikken’s Multi-Lock uses a clamping ring with precision rollers to compress the toolholder’s bore. The result is a strong, concentric grip with favorable damping characteristics, albeit still subject to the same tool-sliding limitation as other toolholders when the cutting force is extreme.

For those extreme cuts, the U.K. group added a secondary, complementary locking system that relies on modifications to the end-mill shank. Two screws press against angled flats on the tool shank to wedge the tool against a stop. The mechanical leverage of this now-patented system, the “X-Treme” clamping, has proven sufficient to prevent the tool from changing position in the holder in even the most aggressive cuts Technicut has taken with its new “TiTan Rippa” tool.

When the new tool and new holder are used together, says Mr. Eckersall, the performance difference Cemented Carbide Inserts is audible. The stability of the holder’s grip on the titanium-cutting end mill is such that cuts in titanium are quiet, even at high metal removal rates. (Go here to see and hear video of a 16-cubic-inch-per-minute cut in titanium 6-4.)

The difference is also measurable, he says. One aircraft-industry manufacturer has adopted the new tooling combination for milling slots in several sizes of titanium engine fan disc. The improvement in metal removal rate from this tooling has reduced the cycle time for one such part from 36 hours to around 11 hours. Meanwhile, the system’s stability contributes to tool life savings that have decreased the number of tool change-outs, so that only six milling tools now do the amount of machining for this part that used to require over 30 tools.

As of yet, the new Lathe Inserts Nikken X-Treme holder is available only for titanium. It is being sold with the Technicut end mill as a system for titanium milling. Mr. Eckersall says the next step is likely to be Inconel. The holder is currently being used in test cutting that is evaluating a new high-metal-removal-rate tool for the nickel-based alloy.
