On December 18, under the auspices of the leaders of the Science and Technology Department of the Municipal Economic Commission, the company held the 2012 Shandong Provincial Technology Innovation Project "J4K-076 CNC Oil Outlet Valve Forming Cylindrical Grinder", "MK1320A/1 ×500CBN CNC grooving special grinder", "J4K-082 CNC gear bevel special grinder", "MK2120 CNC internal grinding machine" appraisal and acceptance meeting, the appraisal and acceptance committee listened to the report of the project team, reviewed the relevant technical materials, inspected After inquiries and discussions, it was concluded that: the oblique plunge grinding wheel frame developed by 076 adopts integral multi-oil wedge and large taper can automatically adjust the clearance dynamic pressure bearing, which has high rigidity and rotation accuracy. The conical surface and the outer circle of the oil valve are once formed and ground to ensure the positional accuracy of the outer circle and the conical surface of the oil valve. MK1320A/1×500CBN has developed an automatic centering film clamp for air pressure detection, which realizes automatic clamping of the workpiece and improves the clamping accuracy. The X-axis sliding table adopts N/O type precision linear roller guide rail, which reduces the friction coefficient and improves improved feed sensitivity and machining accuracy. At the same time, the appraisal and acceptance committee also spoke highly of the other two machine tools. The leaders of the Municipal Economic Commission expressed satisfaction with the completion of the project tasks undertaken by the company, and put forward very sincere suggestions, such as further optimizing the assembly process of the J4K-076 head frame, improving the MK1320A /1×500CBN tailstock waterproofing ability, optimized appearance design of M K2120 machine tool, etc. All four items passed the appraisal and acceptance. The leaders of the Municipal Economic Commission encouraged the company to apply for patents for some key technologies, speed up the pace of product introduction to the market, and create good benefits for the company.
