1 Vibration of lapping machine is an important influencing factor on the lapping quality of diamond cutting tools in mechanical lapping, especially in the precision lapping process.

2 The lapping machine is the important equipment of nonwoven line, affects the quality of products.

3 The lapping machine is the important equipment of nonwoven production line, which affects the quality of products.

4 The roll lapping machine is one of the equipments processing the excircle surface of minor diameter workpiece by lapping. The working accuracy is affected directly by the guide wheel of this machine.

5 An electro-chemical ultra-precision lapping machine with five freedoms of X-, Y- and Z-axis linear movement as well as rotation about X- and Z-axis is developed.

6 A kinematic model of the planet lapping machine is developed.

7 Development and manufacturing from the opening, carding, lapping machine needle into the entire line of paper craft and equipment.

8 Cross - Lapping Machine in nonwoven process makes reciprocating movement which motion with rotary motion during lapping web.

9 At the same time, the application of nuclear belt weigher in lapping machine is designed, and the PID control function can be achieved based on PLC control.

10 To meet the market demand, and on the basis of referring similar products at home and abroad, a new lapping machine for making steel ball is developed.

11 The rotating speed relationship between two independent driving components of lapping machine was established by introducing the definition on "velocity ratio".

12 Further, the control system have been designed based on the operational principle of the lapping machine.

13 During the processing of spherical workpieces on high speed spherical surface solid abrasives lapping machine, we must ensure the surface precision of the workpieces.

14 The reasons for kerosene catching fire of HZ3MZ3220 bearing external lapping machine were analyzed, a series of measure and method were adopted .
