5G, cutting feed rate is 12m/min. This machine tool is designed for accurate treatment only, adoption metallurgy technology makes cast has the biggest tigidity, course of slippery course of axial of main shaft box quenchs, grinding, handiwork is blown grind processing, fixed position precision and repeat fixed position precision for 0.
001mm. The main shaft device of Mitsui machine tool can undertake be compensatinged automatically to temperature change, do not need " heat engine " time. This company offers a variety of main shaft to choose plan, the need that chooses straight drive and positive drive in order to satisfy an user and the need to different torque and rotate speed. Anyhow, HPX63 machine tool has good consistence, tigidity and accuracy, the treatment that fits stuff of steel of alloy of pair of titanium, chromic ferronickel, tool, stainless steel and aluminium very much, apply to part of prototype of aerospace industry, energy industry, compressor, mould, clamping apparatus and tool equipment, car to make and treatment of general high accuracy. Main shaft coupling device to make cutting tool system achieves optimization, coupling device of requirement main shaft can the biggest change the ground to transfer machine tool power. Product of most cutting tool is integral type cutting tool on the market, main shaft clamping force is relatively inferior. Because the tigidity of coupling device is very finite, and radial cooperates need maintain inside value of the least provision. Contact function to obtain stable end panel, need very close together tolerancepublic errand order and degree, accordingly finished cost rises considerably. Although some coupling device can deliver high-power torque, but before achieving the biggest torque, the likelihood bending quadrature that cutting force produces has exceeded coupling device can susceptive limit. The KM4X that Kennajin belongs to a company to produce is the coupling device of KM main shaft of new generation. The design of 3 surface contact of this device increased stability, optimized clamping force distributing and be filled with too cooperate, accordingly, the function of the quadrature that defy a turn of device is 3 times of system of other knife handle. In checking cutting to machine, HPX63 provided the main shaft unit of big torque high power, most high-power is 26/22kW, the biggest torque is 1082 Nm. Coupling device of KM4X 100 main shaft can form the clamping force of 85 KNm, be HSK100 device 2 times much, be BT50 device 3 times (the clamping force of these two device is 40kNm and 25kNm respectively) . Cutting cutting tool used 4 different cutting cutting tool in the test, it is respectively: One takes 7 square but dislocation razor blade, diameter 203.
The end panel milling cutter of 2mm; One takes 7 round bit the end panel milling cutter of identical diameter; A diameter 76.
21mm, length 228.
The corn milling cutter of 6mm (HARVI Ultra) , contain 5 helix platoon, there are 11 bits on every helix platoon; 125mm of a diameter, contain 6 but the flat bottom of dislocation razor blade but dislocation broach (FBI) . Because machine tool and main shaft have enough power output, and main shaft coupling device has outstanding clamping force, test treatment result is very accordingly outstanding. The metallic excision rate of milling cutter of end panel of quadrate razor blade was achieved 88.
74cm2/min, main shaft speed is 64 Min-1, cutting deepness is 12mm, cutting width is 45mm, feed rate is 164.
3mm/min. Width of 73 Min-1, cutting is in main shaft speed 177.
3mm of deepness of 8mm, cutting, feed is led 88.
Below the condition of 9mm/min, the metallic excision rate of milling cutter of end panel of circular razor blade is 47.
42cm2/min. Milling cutter of HARVI Ultra corn can undertake the cutting of X axis and Y axis direction at the same time, it is for rate of 171min-1, feed in main shaft speed 101.
Deepness of 6mm/min, cutting is for width of 40mm, cutting 76.
Below 21mm condition, its are the biggest metallic excision rate can amount to 309cm2/min. FBI broach got a smooth bottom outlet on titanium material workpiece, lead for 102min-1, feed in main shaft speed 10.
Below the condition of 125mm of 2mm/min, aperture, metallic excision rate is 125.
2cm2/min. After drilling the first hole, rotate workpiece on main shaft 45 ° horn drills an inclined hole again, inclined hole crosses the bore brim point of the first aperture. Although machine a process to be serious interrupted cutting, but machine tool and broach show good performance. Function optimization and convention or general-purpose machine tool photograph is compared, the metallic excision rate that HPX63 is processing titanium alloy work can rise 1.
5 - 2 times. Coupling device of KM4X main shaft has enough clamping force and had used be filled with cooperate means, add man-hour to be able to use higher rotate speed, torque output is the biggest change. The machines efficiency and cutting tool cutting function of the machine tool gets remarkable promotion. In addition, the function of coupling device of KM4X100 main shaft can reach the performance level of HSK125. Not only such, still can avoid to use library of main shaft of train in excess specified length, large the arm that change a knife, large cutting tool and other to be able to increase a machine tool to cover an area of the element of area device. Use correct cutting tool and main shaft coupling device to be able to reduce the size of the machine tool, mix in titanium material treatment efficiency improves significantly in treatment of material of alloy of other difficult cutting. Main shaft coupling device can ensure the function of cutting tool is achieved the biggest change, can develop the property of cutting blade, milling cutter, broach and lathe tool adequately, improve treatment efficiency. Mitsui Seiki machine tool has the durable sex of train in excess specified length, in the service life that train in excess specified length still has for long below heavy-duty treatment condition, can improve treatment efficiency of the client greatly. The production quality of the machine tool is higher, the long-term movement cost of the machine tool is lower, because can fall the machine down time of the machine tool,come lowest. In addition, when the client is buying equipment, the company still can offer satisfactory quality to assure to the client, in order to make sure the machine tool has the locomotive time of extremely tall accuracy and train in excess specified length in be used for a long time.
