Ultra-precision processing machine with air spindle · FAG Bearings

Development of products clutch bearing portion of the inflatable structure has been improved, high-speed rotation (20000 rpm) accuracy value asynchronous runout (NRRO) controlled at 0.005μm below (actual measurement value), the original 1/2, the Department of "the industry's highest" (the company). Also constructed by using a low heat, the machining of the workpiece surface position control of 1μm or less, only the original 1/3.
Clip can be avoided by using a vacuum suction head of the spindle grinding fluid into the air-flow preventing internal structure, and the use of non-contact seal of the inflatable structure, improved dust and waterproofness. To enable it to operate more stably.
Igus production function which detects the plastic bearings can be adjusted according to the angle deviation, and in many areas may be used instead of conventional metal parts. Igus means that when these functions with a special metal detector is mounted to the fixed bearing on the machine, the machine will not create any pollution processed products.Eccentric bearings installed on the device caused after the reversal should not be more flexible reasons, the main reasons are the following aspects:
d: The original bearing clearance is small, in this inner ring and the shaft, the bearing outer ring and bearing fit, due to large amount of interference, so that the original internal Precision bearing clearance is reduced, resulting in eccentric bearing rotation is not flexible ;
b: eccentric bearing not clean during installation, a foreign body in the bearing inner and outer raceway and between the rollers, causing the bearing rotation is not flexible;
a: install nsk bearings, koyo bearing, ntn bearing, skf bearing, iko bearing eccentric bearing, the equipment and the transfer of certain fixed parts may lead to bearing friction rotary member has not flexible;
e: If it is a large eccentric bearing, the bearing installation is complete, give the bearings plus a minimum radial load, in order to ensure a flexible bearing rotation.
c: eccentric bearings during the installation process, due to improper installation of the cage deformation, resulting roller can rotate flexibly
