1) having the right values: the premise of success; We have the

right attitude of life: positive, empathetic, confident, introspective,

courageous, and open-minded. 3) basic behaviors: pursuing ideal,

discovering interests, effective execution, hard work, interpersonal

communication, cooperative communication, etc. If you are looking for

the path to success in the above logical order, it is not impossible to

achieve a pluralistic success.

The application of magnetic abrasive technology in China is not

widely used, and the key to popularizing the process is the development

and development of practical machine tool (magnetic grinding machine).

electromagnetic sensor structure 1 lathe structure of modified magnetic

grinding machine With the CA6140 engine lathe modification of magnetic grinding machine structure as shown in figure 1. The grinding workpiece

is fixed to the top and rear top 8 of the attached core axis 6. The

additional core axis 6 is mounted on the pedestal 5 by sliding bearing,

which is connected by the spline and the spindle of the machine tool,

and the top is installed at the other end. 14 can be installed in

the machine tool bed side of the motor through additional core shaft

drives the swinging motion artifacts, namely motor through the

transmission of dynamic belt 13 would be eccentric motion transmission

to a certain amount of centripetal bearing 3, then pass the movement to

attach the flywheel on the spindle 4; The recovery force of the swing

motion is provided by the rear top spring. The electromagnetic inductor

12 is mounted on the transverse slide, and the two magnetic poles can be

moved synchronously to each other, and can be moved along the guide rail

along with the horizontal sliding plate to realize the longitudinal feed

of the grinding. The device installed in the position of the box can

control the power of the electromagnetic coils 7 and the motion of the

sensor. The longitudinal feed of the tool holder is driven by the

hydraulic device. Since the center of the magnetic sensor is usually

higher than the center of the machine spindle, the front and rear seat

of the machine must be raised so as to install additional pad 2 and 10

on the bed. Magnetic grinding is made by electromagnetic sensors

installed in the position of the lathe tool, which generate magnetic

fields and carry magnetic abrasive. The structure of the electromagnetic

sensor is shown in FIG. 2, which consists of the base plate 1, the slide block 2 of the l-shaped magnetic conductor 3, the electromagnetic coil 4,

and the magnetic pole head 5. Material plate 8 is used to collect

coolant. A screw with left and right screws is installed in the bottom

plate. The sliders and floor boards are made of non - magnetic materials

with good abrasion resistance. All parts of the magnetic circuit should

be made of magnetic materials with high magnetic and saturated magnetic

induction. Electromagnetic induction coil electricity, head to the two

poles of clearance

Sprinkle in magnetic abrasive, formed under the action of magnetic

abrasive in the magnetic field force brush brush (grinding) and pressure

to the workpiece, at this time through the spindle rotation can begin

abrasive. The electromagnetic sensor is used to drive down the shaft of

the workpiece along the axis of the workpiece and the whole length of

the workpiece is ground.

Assumes that the magnetic flux entirely by magnetic circuit section

(regardless of the magnetic flux leakage), all the air gap media are air,

air gap joint is zero. The magnetic conductor size of magnetic circuit

is shown in FIG. 3. Work clearance area S = mA = 8 x 230 = 1.84 x 10-3m2,

in the form: the magnetic pole head width A = 230mm, the magnetic pole

head surrounds the part of the workpiece with the length m = 8mm, the

work clearance is 2mm, the saturation magnetic induction of the steel is
