The turn mill lathe+MS series has a 30° inclined HT300 gray cast iron bed structure standard with linear guideway.EUMASPINNER precision electrical main and sub-spindle standard with water cooling device,nose runout below 0.001m, taper from A2-5 to A2-8.Range of working diameter from 320mm to 480mm,working length from 400mm to 850mm.Fast change live tool turret could be BMT or VDI type to handle the cutting and milling.C0/C1 ball screw for ultra high accuracy production and machine body constant temperature to be customized.
Base on our Turn mill lathe+C series we develop this Turn mill lathe+MS structure with sub spindle which the C1 and C2 axes provide positioning resolution up to 0.001 degree.Accomplish three dimensional contouring,combine round and prismatic machining by harmonized control of the spindles with the X and Z axes. Synchronization between electrical main and sub spindle at any rotation speed can be programmed to perform part transfer for secondary machining, enhancing production efficiency and reducing idle time.
EUMASPINNER's EL line of Turn mill lathe the bed is made of one-piece HT300 gray cast iron, are integrallycast, hardened, and ground. They possess a wide rail span, low center of gravity, large bed swing, and high stiffness while delivering excellent drainage and chip removal performance. The base bed's interior has a heavily distributed strengthening ribs design, effectively eliminating deformation caused by shear and tensile stress.
The headstock and ballscrew anchoring seat require precise scraping for tighter alignments and tolerances between mating parts, ensuring excellent overall accuracy and machine stability.
Skilled hand scraping creates oil pockets with high and low spot texture patterns, aligning the sliding surfaces between saddle and box guideways for smooth gliding while reducing wear and heat from friction.
Oversized AC servo motors are used to deliver powerful thrust for high feed rates and accurate cutting. Large diameter pretensioned precision customized HIWIN/THK ball screws are directly connected to the drive mechanism for nearly backlash free movement. Full travel repeat accuracy reach to 0.003 mm on 1000mm length according to German VDI3441 standard. C0 class ultra high accuracy ball screw is optional.
INNA/THK linear guide way design provides low friction coefficient,and minimize the
difference between dynamic and static friction. Therefore,the stick-slip will not occur during sub-micron feeding.
