Wenzhou Euma Machinery Co.,ltd

◼Description
◾Overview
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.

◾Super Rigid One-Piece Cast Bed
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.

◾Meticulous hand-scraping work
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.

◾Balls crew Drive Mechanism
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.

◾Linear Guideway
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.
