As produce to the machine tool can, precision and the addition that dynamic function asks, direct drive technology is used already increasingly in order to satisfy above a variety of demand. Especially electric machinery of direct driving moment, can rise for the function of the machine tool bring major change. The application of electric machinery of straight drive moment of force, still have use cost integratedly what drop a client, simplify the design of the machine and reduce maintenance to safeguard wait for an advantage. Pitching moment electric machinery is joined into direct drive by the design means, eliminated the mechanical gearing such as worm of gear case, worm wheel, synchronous belt namely, realized the direct link of mechanical load and electric machinery rotor. Such join means can provide high dynamic performance, eliminated the clearance of transmission and defer, offer a machine tool to machine the extremely tall tigidity of need. American division Er Morgan (Kollmorgen) at 20 centuries the fifties, gave electric machinery of moment of force of the first straight drive with joint development of Masschusetts Institute of Technology, apply the earliest on revolving stage of inertial control and guide. Of after this 60 old in the product line that the electromagnetism that its have place and Electromechanical design experience all use at notting have to brush electric machinery of permanent magnetism straight drive, the high-powered maintenance-free that develops all sorts of set is straight drive rotates electric machinery and linear electric machinery. The article introduced KBM electric machinery to be in my company the success on grinding machine of tool of 5 linkage numerical control uses the 6 rods of own research and development. This machine tool is light of limited company of numerical control of Dalian division heart, Dalian manufacturer of famous tool of home of combination of limited company of engineering of modern science and technology and university develop jointly. Body of machine tool bed is cylindrical, use a balance to be designed symmetrically, structural stability is tall, hot field distributings equably, facilitating compensation. Base humanness makes stone material, have damp damping, high accuracy, sex suction shock is good, thermal stability is good, the character such as corrosion resistance. Grinding spindle introduces drive of series connection of double electric machinery, and drive is completely symmetrical, balance sex is good. Axis of B, C uses electric machinery of moment of force of straight drive type to undertake delivering. B axis can realize 360 ° of ± to rotate, improve treatment efficiency substantially, reduce cutting tool to repeat the time that hold clip. This machine can machine 2~8 blade a variety of standards such as broach of straight handle milling cutter, ball head milling cutter, broach, a flight of stairs, tap and nonstandard cutting tool and outside circle and drift grinding treatment. The system of numerical control of type of fiber-optic bus line that numerical control system uses Dalian light to silver coin, grinding software uses the craft software that Dalian light silvers coin to be developed independently. This machine tool already was in the application international invention such as China, Australia, United States, Japan, European Union is patent two.

The high-powered entrance that at present home uses grinding machine of tool of numerical control of linkage of 5 axes, 6 axes, basically Shiliboge, WALTER, WENDT, Shu Te, Sa Ke, ANCA, Dirk, TTB waits for international brand. Grinding machine of numerical control tool uses the world's advanced data commonly the advanced module design such as system of location of system of electric control software, accurate slideway and system of guide screw campaign, accurate grating and feedback of servo electric machinery. Cole KBM electric machinery is in Morgan the application on this type in recent years, the use day on grinding spindle and workpiece main shaft increases the straight drive electric machinery with compact structure gradually. Straight drive main shaft can avoid the clearance on mechanical drive, the system of worm of accurate worm wheel that replaces original cost to hold high, saved installation bulk, make sure the system stabilizes balanced precision. Choice of material of affirmatory, installation, water-cooling reachs kind of the type selecting that passes earlier stage, installation efficiency analysis, to model affirm finally. We chose Cole KBM series does not have Morgan casing electric machinery, KBM used Cole without series of casing electric machinery Morgan the company's newest direct drive technology, have the following characteristic: The temperature of winding of interior of 155C of stator winding · with completely sealed · lasts thermal resistor of ability · PTC (avalanche type) of magnet of rotor of · of magnet of Tie Peng of neodymium of rare earth of overload protection · prevent breakdown frequency band automatically, UL of · of compatible RoHS, CE attestation · but the advantage clearly that custom-built rotor hub dimension chooses electric machinery of KBM moment of force to bring: Defend the work cost of little, maintenance short, service life grows low, machine down time, efficiency is like gear-box and synchronous belt than mechanical gearing at least the system is expensive 10% . The structure is compact, performance is good, take up the space is little. Additional, these electric machinery can be had between drive rotor and load bigger inertial compared high inertial load. At the same time they have superior dynamic performance, quicken and slowdown time is extremely short, promote a machine property considerably. CNC Milling
