Turn mill lathe

Overview

By nearly 20 years experience in slant bed lathe production.EUMASPINNER has amassed technical expertise and a team of experienced engineers. This superb static and dynamic stability EL series turning lathe was born 20 years ago in early 2000s. We developed the optimal machine structure design to provide the perfect balance of brute power stability and precision to build a compact lathe delivering high performance.

Super Rigid One-Piece Cast Bed

EUMASPINNER's EL line of Turning lathe bed is made of one-piece HT300 gray cast iron, are integrally cast, 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.

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.
