CKJ3463 CNC lathe Shenyang Machine Tool Co., Ltd. developed CKJ3463 CNC lathe is a two coordinates, continuous control of CNC lathes. The lathe uses FANUC-0T-MATE system control. The machine is equipped with four-station CNC turret and a six-station turret, mechanical, electrical, hydraulic integration control, can realize more multi-bladed knife cutting, reaming, chamfering and other processes. CKJ3463 CNC lathe is ideal for a big power, good rigidity, high precision heavy cutting high-efficiency machining. It applies to all kinds of shapes machining plate, sets of parts, such as flanges, gear blanks, shells and other complex, high precision parts.
MY7760 type spindle double-face grinder Hangzhou Machine Tool Plant developed MY7760-type double-face grinder spindle single-column structure, feed sensitivity of 0.25Lm. Machines with CNC control, grinding DC adjustable speed motor, Dresser with double cylinder reciprocating linear guide method, quill fast lifting and micro-feed driven by a servo motor, hydraulic eliminate the gap device, water cooling spindle center .
With rolling ball screw technology manufacturing NC device Japan Nishijima company recently developed a technology to produce using rolling ball screw NC device and has started to accept user orders. Rolling device controlled by computer can properly and continuously produce a variety of complex shapes of the ball screw.
2-NTR16CNC / AC type of new devices using two metal roll forming, rolling maximum pressure of 12t, the use of rotary motion in rolling out the ball screw within seconds. Computer controlled roll position and rotation speed, processing errors can reach 5Lm less. Die processing special processing center Toyota to develop mold processing market. Zibo Jaguar Land Rover the company mainly for auto parts in the field, not only to expand the autumn of 1997 the development of ultra high-speed mold processing machine series, but the series has developed a new mold machining center. The series machining center is equipped with thermal deformation countermeasures and special programming techniques to achieve high efficiency, high-precision machining mold, to help users develop the market.
Zirconia bearing means to extend the life of the planetary gear drive shaft British company Maxon portion planetary gear unit using zirconia ceramic material of the bearing. Output speed planetary gear train was low, but bear torque is great, leaving the bearing lubricant may not work well on its moving parts. Dynamic mechanical properties of liquid smoke purifier Beijing this lubricating oil is difficult to improve, thus requiring a planetary gear train means to be both a good bearing wear and bearing characteristics. This planetary gear unit bearings zirconia has successfully test run a year ago, it showed its working life than metal bearings extend 3 to 5 times. JammesIndustrie large rolling mill in France JammesIndustrie company recently successfully developed a largest rolling mill, used to structure the new Airbus A340-600 rolling body.
Airbus fuselage of different shapes and sizes of aluminum pieces of composition, aluminum is about 10m, a thickness of about 13mm. The new rolling mill in the rolling mill, weighing about 70t.JammesIndustrie companies can be rolled to the fuselage, wing leading edge, structure and horizontal stabilizer leading edge of the tail cone. Member length ranging from 1.8m to 12.2m, the radius of curvature of unrestricted member.
The rolling mill roll pressure of 300t, a total of three rolls, the axis spacing is adjustable. Important results of this latest technology is a new system can be used to compensate for any roll bending. This compensation system consists of several motorized tilting blocks, so that all the rolls are maintained over the entire length parallel to each other.
