If you have attended the 2016IMTS International Machine Tool Fair, you will certainly notice the release of Kennel Metal's products, Kenya Metal has introduced the most rigid, high precision, and efficient modular end mill products. Named DUO-LOCK ™, a tool supplier in Latrobe, Pennsylvania, promised that this newly developed tooling product will revolutionize the modular tool market, which is a meaningful predictor. DUO-LOCK products A year later, the product manufacturer once again announced that this extremely successful tool product line will be significantly expanded to add more members.
development path
For customers who have not yet used this product, DUO-LOCK is a modular end mill with full carbide end mill performance. This product is patented with Kenner Metal KM ™ or KM4X ™ tool similar to the double cone interface device to ensure that the axial runout does not exceed 5μm (.0002in.) Limit, Z-axis repeat positioning accuracy of 10μm (.0004in.) Or higher accuracy. Because to ensure that 50μm .002in.) The repeatability of the tool change is not necessary for offset adjustment or positioning deviation adjustment after the tool change. This product also has a very good rigidity, with a unique and patented »intelligent» threaded interface device, Compared with competing products, it can absorb more than 25% of the torque. The results show that DUO-LOCK can be 1xD full width of the milling slot, and in the case of 50% radial knife consumption of 1.xD side milling, or even Can also be used for titanium materials and similar high strength alloy materials processing.
Thilo Mueller, product manager for Kennametal Solid Carbide End Mill, believes that the first DUO-LOCK product line includes more than 400 series products, adding a small number of products at the beginning of the spring, but this product line Products have doubled compared to existing products »Last year's IMTS International Machine Tool Show introduced the first round of HARVI end mills, including HARVI I, HARVI II, and HARVI III troughs, with a diameter range of (16mm) to 1.25in. (32mm), »Mueller said.» This product line extension includes some new size specifications, and some new tool types. This improves the versatility of DUO-LOCK , So that more customers can take advantage of this performance and reliable products in terms of strength and accuracy advantages.
The DUO-LOCK series now offers a variety of rounded corners and chamfering tools.
Design Features
Based on the following product characteristics, DUO-LOCK HARVI can meet almost all applications of the ideal carbide cutting tool applications.
• The variable helix angle design of HARVI avoids the vibration of the knife, even in the most difficult processing of the material.
• Asymmetric helix angle design has higher feed rate performance than conventional end mill products.
• Eccentric arcs can increase the stability of the blade, thus significantly extending tool life.
• DUO-LOCK HARVI uses a tapered core design to ensure excellent rigidity during harsh conditions.
• Axial and radial front angles are specially designed to reduce cutting forces.
• A tool can meet the roughing and finishing application requirements, or the same tool holder uses special roughing tools and finishing tools.
According to the groove and tool size, can provide four-blade to six-edge HARVI tool, there are several PVD coated microcrystalline cemented carbide material, including KCSM15 material, which is a special for the aerospace industry, titanium materials And other high-temperature alloy materials. KCPM15 material suitable for steel, stainless steel, and cast iron materials processing; composite coating KC643M is a commonly used material for a variety of materials, wet processing applications. All materials can be used for hardness Up to 52HRC material processing, all materials in the processing of difficult cutting materials to reduce the depth of damage, reduce the edge of wear and tear, reduce the formation of crescent depression has a very good performance.
RSM II FSDE finishing tool with 36-degree spiral angle and W-shaped edge design, especially for titanium materials and similar materials, precision machining
Expand the product
So, what products are added to this series? DUO-LOCK modular end mill series now adds a lot of small size products, size specifications from 0.375in (10mm) from the product line also increased the chamfering and fillet Processing tools, and a variety of the latest trough products, for example, recently introduced several new »corn» coarse milling cutter. A ripple tooth design products can be processed in the formation of small chips, in the large metal removal The use of the same slot design, but its design is used in mold manufacturing and similar applications in the 3D profiling process. A space shuttle industry-specific tool The unique groove design, in the processing of high-temperature alloy materials can reduce the cutting force, the tip of the round design can reduce the chipping phenomenon.
In the field of finishing applications, Kenner Metals has developed a six-blade, 45-degree helix tool with a similar design to the HARVI III aerospace industry, but this improved product is better in steel and stainless steel (Other than the tool diameter size), the patented W-shaped edge design, and the asymmetric edge distribution, which in the aerospace industry, the processing of high-temperature alloy materials To avoid the knife vibration phenomenon, in the high feed processing also have a good performance.Finally, Kenner Metal Company also developed MaxiMet ™ two-edged and three-edged high shear end mill products, this product can be used for aluminum Material for efficient roughing applications, while the fillet fillet near the location of a fine grinding edge edge, so in the finishing can also form a square side wall and smooth bottom.
Need to carry out large cutting the amount of aluminum processing? Application DUO-LOCK interface device MaxiMet and K600 material combination can fully meet this application needs
Kenner Metals has also expanded its tool holder products to provide several long-shaped straight shank and taper shank steel arbor products, these products can be customized according to customer specific needs in addition, there are a variety of other knife handle products , Including existing HSK, PSC, CAT, DIN and BT flange-type shank products »Our HARVI series, the latest rough and fine milling cutters, and MaxiMet products have excellent market positioning. Good to meet the needs of our customers, Mueller said.If you want to try these new tool products, he made some suggestions. »You can not manually replace the torque wrench, you should always use Torque Master torque wrench, according to the product The sample data or the torque parameters in the NOVO system, and clean the threaded parts before use, and each blade is coated with a small amount of grease to prevent corrosion before shipment, which must be removed during use. It may be argued that all tool holders should be slightly lubricated, but not for DUO-LOCK. Before using the tool correctly, the smart thread must Must be clean and dry, and the surface of the blade mount is the same. This will allow you to see very satisfactory results.
