It is said that the chip forming device with positive rake angle on the blade can reduce the cutting force and reduce the cutting power consumption by 15% – 25%. It can also guide the chip to leave the cutting area, so as to prevent the side of the machined part from being scratched by the chip. The chip is guided to flow inward (tool center) rather than outward (workpiece sidewall). The tool is equipped with two types of blades, one is used for slotting and the other is for cutting.
Tanglot milling cutter can be supplied as FDN flange type or SDN disc type cutter. The tool width can be adjusted according to the tool collet used and the blades with different widths. The range of tool diameter is 100-250mm, and the width of tool is 6.0-14.6mm. The new tool can be used for grooving and cutting of automobile bearing cover, steering knuckle and connecting rod, as well as other conventional slotting.
(2) Seco tools Inc. claims its new crown MF5 chip breaker has increased tool life by 67% in field cutting tests and improved chip control in 41% of tests. According to the company, MF5 chip breaker is optimized for semi finish machining related to near net machining. Its chip breaking groove can generate very small cutting force and allow the tool to carry out advanced cutting at a cutting depth of 0.5-2.7mm. MF5 chip breaker adopts crown shape with three sharp forks, chip guiding platform and cooling channel, which is conducive to small deep cutting and ultra-high pressure cooling. In addition, the open geometry angle can reduce the cutting force. The chip breaker has a ground island shaped protuberance, which can improve the positioning of the blade and is conducive to the heat dissipation of the workpiece and cutting edge.
MF5 chip breaker is used in 8 kinds of positive C-type and standard W-type blades (brand numbers are TK1000, tk2000, tp1000, tp3000 and duratomic tp2500). When roughing the steel rock bit (hardness hrc42 ～ 45), the tool life of TK1000 made of MF5 chip breaker is 5 times longer than that of a competitive chip breaker. In the similar cutting experiment with MF5 tp2500 blade, compared with tp2000 blade with M5 chip breaker, the productivity is increased by 55% and the tool life is increased by 360%.
(3) Sandvik Coromant’s new LC blade geometry prevents chip clogging that often occurs when cutting difficult to machine materials. Because of the edge shape design of LC blade, the risk of chip accumulation in machining low carbon steel workpiece is reduced, so the tool life and machining surface finish are improved. The scraping edge can increase the feed rate. The company provides LC turning blade grades for low carbon steel machining, including gc4225, gc1525 and gc2025.
(4) It is designed by guhring-48, Inc., which is easy to produce fine cutting chips. The 3365 series allows slotting and rough milling of steel parts at high cutting speeds and feed rates, while achieving maximum metal removal with minimum torque horsepower, the company said. The milling cutter is also suitable for machining titanium and titanium alloy aviation materials and nickel base alloy.
Cobalt collar has also launched 3376 series aluitech LR and 3364 series roughtech Alu three groove carbide end mills for processing aluminum and aluminum alloys. The above three kinds of end milling cutter series are supplied according to the standard specifications, and the cutter diameter ranges from 6.0 mm to 20.0 mm.
Mainly engaged in a variety of plastic mold design, manufacturing and plastic products injection, injection, pad printing and other processing services. The company produces a wide range of mold types, including various household appliances, computer weekly products, communication products, power tools and CD, DVD, MP3, MP4 categories, etc., which can be used to make rapid template mold and two-color molding mold. It can take into account large, medium and small die. The largest mold size is 2 m * 1 m, and the maximum weight can reach 8 tons.
