In order to increase the efficiency of mold processing and reduce manufacturing costs, five-axis machining centers and five-axis CAM machining technologies can be used. The advantages are that they can select the best machining conditions, improve the machining accuracy and processing quality, and achieve process intensification. To achieve this goal, optimized high-precision tools and high-performance tool holders (or tool holders) are indispensable elements. The following is a brief introduction of the newly developed high-speed cutting (HSC) cemented carbide end mills and powRgrip powerful clamping shanks.
(1) HSC carbide end mills
HSC carbide end mills have excellent performance, can significantly reduce the cost of processing, can fully play the function of the five-axis machining center in high-speed milling, and significantly shorten the processing time.
HSC carbide end mill has the following characteristics: 1 high-performance carbide substrate; 2 stable cutting edge for high-speed milling; 3 TiAlN coating with high heat resistance; 4 tool neck diameter smaller than the shank diameter; 5 Tool holder accuracy: h5;6 End mill outer diameter accuracy: φ8mm or less: 0～-0.02mm; φ8mm or more: 0～-0.04mm; Ball head radius accuracy: ±0.01mm; 7 Millable HRC66 and below hardness All workpiece materials; 8φ 16mm end mills have up to 16 teeth.
(2) powRgrip strong clamping handle
In order to give full play to the machining performance of HSC carbide end mills, it is very important to improve the rigidity and precision of the shank, which is also one of the topics for achieving high level mold processing. The newly-developed PowRgrip strong clamping shank is a high-rigidity, high-precision tool clamping system that hydraulically presses a small-tapered collet into a shank to achieve tool clamping and solves the heat existing in the past. The problems of long press-fitting tools, restrictions on the tool shank material, and short tool holder life have increased the rigidity of the shank and the precision of the traverse.
PowRgrip strong clamping handle has the following characteristics: 1 short tool change time (within 10 seconds); 2 long service life (20000); 3 large torque fastening (φ20mm handle: 380Nm); 4 high jump accuracy (3μm or less); 5 Clamping performance has nothing to do with the tool material; 6 knife clip overhang adjustment accuracy is high (within 10μm); 7 Absorbing cutting vibration ability.
Processing example: Milling of S45C carbon steel with a φ16 mm end mill, speed 6000 r/min, feed per tooth 0.1 mm. The machined surface roughness, Ra, of the hot press-fit fixtures, hydraulic fixtures, and powRgrip toolholders were tested separately. The results show that the tool life of the powRgrip toolholders was improved by 180% compared to the thermocompression fixtures. Tool costs can save costs by 44%.
U Bend Tubes for boiler & heat exchanger
'U' Bend Stainless Steel Tubes are manufactured in our plant as per the customer requirements. Bends can be Heat Treated in accordance with Clients` requirements followed by hydrostatic testing and dye penetrant testing if required.
'U' bent tubes are widely used in heat-exchanger systems. Heat exchanger equipment on the basis of stainless U-tube is essential in strategically important and critical fields nuclear and petrochemical machine building.
U-tube heat exchangers Designed for high temperature applications, especially steam condensing or hot oil systems. Thïs model is selected when differential expansion makes a fixed tube sheet exchanger unsuitable and when conditions preclude a floating head type (HPF) selection.
Surface condition Finished U-tubes shall be free of scale, without scratches after bending
