Speed escalating EPT box of 135m ending mill
Composition of pace increasing EPT
EPT elements of speed increasing EPT situation(reduced situation, center case and protect), help base, big EPT, EPT aXiHu (West Lake) Dis.s, EPTl wheel and lubrication system.

2.EPT attributes
Box is melt with thick metal with fantastic top quality to achieve the depth that the case required. Case should just take anxiety ageing treatment before the produce to achieve the steadiness that necessary. Higher precision lathe machining is utilised for the assembly of cases to insure the finding accuracy of each and every bearing holes and connected joint area.
Huge EPTs and EPT shaft employed carbon alloy steel forging blank, following roughing, workpiece need to have to just take ultrasonic flaw detection process to quench. In orEPTto make sure the tooth area with high hardness, tooth area want to get carburizing and quenching treatment following semi-ending .Fantastic grind of tooth surface to insure the higher accuracy, soon after finishing the production of EPT, the equilibrium take a look at is required, the trail velocity is 1500r/min and the stability precision grade is G2.5. the path pace of EPTl wheel is 3500r/min, the harmony precision quality is G1, in so to guarantee the rotary precision of the EPTs.
EPT shaft use the alloy metal forging blank, EPT shaft requires quenched to make certain the depth and durableness. Soon after the semi- finishing, EPT require to grind to ensure the precision of every workpiece.
When the assemble finished, the no-loading take a look at need to be keep 2-4hours, the pace is 1100r/min, the temperature of shaft need to not exceed 40 ordmC,the perform of EPT should be easy, no hitting sounds and concussion, each and every joint surface area should not have oil spill phenomenon.
