Furthermore, WE CAN Create Custom-made VARIATORS, GEARED MOTORS, Electric MOTORS AND OTHER HYDRAULIC Items According TO CUSTOMERS’ DRAWINGS. The substantial precise CNC equipment, such as Slow-feeding wire-minimize device, jig grinding machine and electrical discharge machine, makes certain the prime high quality precision of mould processing, with the higher effective and environmental protection acid rolling line getting the greatest uncooked materials converting gear in the area in china The wildly use of automatic milling equipment, large-pace automatic feeding punch, substantial speed automatic rolling and assembling machine guarantees the large good quality and efficiency of components and chain producing. If you require any info or samples, you should contact us and you will have our soon reply. Pace Rising EPT for The Very hot Rolling Mill Line
The EPT system adopts hardened-EPT speed EPT comma which has acompacted structure with decrease noise and greater EPT efficiency interval

two comma EPT attributes
Box is soften with thick metal with great high quality to achieve the depth that the case necessary period of time Case ought to take tension ageing remedy ahead of the create to achieve the steadiness that essential period
Big EPTs and EPT shaft employed carbon alloy metal forging blank comma right after roughing comma workpiece need to have to consider ultrasonic flaw detection process to quench period of time In orEPTto make sure the tooth surface with substantial hardness comma tooth floor require to get carburizing and quenching therapy following semi-ending time period Good grind of tooth surface to insure the high precision comma right after finishing the manufacturing of EPT comma the equilibrium test is essential comma the encounter speed is 1500r solmin and the equilibrium amount is G2 period5 interval
EPT shaft use the alloy steel forging blank comma EPT shaft normally takes quenched to make confident the intensity and durableness interval After the semi- finishing comma EPT need to grind to assure the accuracy of each and every workpiece time period
When the assemble completed comma the no-loading take a look at ought to be hold 2-4hours comma the pace is 1200r solmin comma the temperature of shaft ought to not exceed 60 ordm C comma the work of EPT need to be smooth comma no hitting noise and concussion comma every single joint floor ought to not have oil spill phenomenon time period
