Grinder of seat surface of the aperture in the high-end nicety numerical control of own innovation

003mm. This main shaft is sleeve type construction, circumgyrate precision is tall, adjust convenient, have taller service life and tigidity, can bear enough axial grinding power. Graph this machine tool radial uses Nextpage of composition of structure of grinder of seat surface of the aperture in the high-end nicety numerical control of Inc. of the 2 machine tools that do not have stannum stretch and filmy clip holds the circle outside workpiece, axial to use cone to assist fixed position, ensured diaphragm center is secured do not move, axes direction won't appear displacement (show) 3 times like the graph, solved common film to chuck secures brim means because of using and bring about displacement of diaphragm center occurrence axial thereby, destroy the problem with workpiece axial standard fixed position thereby. Normally, filmy chuck is in clamp process, the requirement is pure radial load to the clamping force of workpiece. Adopt afore-mentioned plan, when installing the card claw on diaphragm to tighten up, its reply force is perpendicular at the surface outside workpiece, this force can serve as pure radial load. The safe mode with this kind of mechanical clamp of filmy chuck, loose pneumatic, although be when unexpected power failure, still can clamp workpiece. The clamp of clamping apparatus piece after be being used for a long time if have,wear away, can make through radial adjustment its satisfy a requirement. Changing when grinding workpiece, need pair of new clamp only piece prop up with end panel undertake be grindinged oneself can. After workpiece clamp reachs the designated position, protective switch can issue signal, rise to protect action. Graph the design structure that 3 radial use stretch film to place the circle outside holding work, axial to use cone to assist fixed position because the grinding area with oily pump fine deep, consequently requirement emery wheel receives senior staff also must fine grow again, and rotate speed must very tall, achieve 70000 ～ 100000r/min. If before the treatment of line working procedure accumulates an error or heat treatment has been out of shape big, emery wheel produces collision in the meeting when feed and workpiece and jockey discovers not easily again, right now, if numerical control system also did not show, can bring serious consequence, touch broken emery wheel gently, emery wheel receives senior staff twist off, weigh an attaint of electric main shaft, minatory even person is safe. Place to because install,avoid undeserved or surplus is too large and brought loss, the head of this machine tool wore unit to configure AE of equestrian Er Persia to prevent collision plant, this device uses position of grinding of monitoring of sound wave sensor. Cent is sound wave sensor stator and rotor two parts, install the main shaft that be worn at relatively fixed head and rotates respectively. It is normal to appear to be not normal circumstance and bring about main shaft to be not when grinding process when vibration, sensor can issue alarm signal to the system, make the machine tool stops to move or change all sorts of parameter to correct grinding condition. This one function of sensor still applies to pair of knives. This machine tool configured main shaft of report of 3 emery wheel in all, collateral place go up in workbench of move back and forth, use at the aperture in grinding, seat surface and end panel respectively, place is CBN emery wheel with grinding emery wheel, the rotate speed of the aperture in its grinding and seat surface achieves 90000r/min. Among them, of the structure of emery wheel extension bar of tall tigidity and electric main shaft cooperating is crucial, the oneself circumgyrate precision of emery wheel extension bar and electric main shaft is core, to this, through drawing lessons from foreign technology, used what be hard alloy endlong to receive senior staff, front-mounted can change the CBN emery wheel of type, at present this one structure already passed high speed spin test. Come true to the nap of emery wheel by King Kong gyro wheel. Answer the characteristic that reachs tall tigidity quickly to ask to satisfy feed orgnaization, the feed orgnaization of the machine tool, reciprocator uses whole sealing formula static press slideway, static press slideway to have coefficient of friction small, service life is long, not easy precision of creeping, motion is tall, bear the weight of muscularity, suck brace up the gender is good reach the good point with smooth motion. Introduce linear electromotor drive, match linear grating feet to control dimension accurately. The resolution of the machine tool is amounted to 0.

0002mm. General, mechanical drive than electric the trends of yuan of parts of an apparatus answers time big class of a few amounts, because a few noises cancelled to answer in the system the mechanical drive with time bigger constant (be like guide screw) , the trends that improved system of whole closed-loop control significantly consequently answers function, reduced the tracking error that brings because of transmission system lag when interpolation. In the meantime, detect through linear position feedback control, raised precision of machine tool fixed position. As a result of " 0 drive " high speed answers a gender, its add decelerate process to shorten apparently, the instant when starting reachs high speed, when high speed moves, can stop definitely for an instant again. Because do not have intermediate transmission link, avoided the energy loss of mechanical attrition. Relative to the drive of ball guide screw at the tradition, linear electromotor is more adjacent to the active force of slide at slide centroid, what produce overturn moment of force is smaller, efficiency is taller.
