Optimum Structural Design

With years of eff ort in research and development, slant bed CNC lathes will off er unique rigidity. The design concept behind the CH-20 and CH-26 series is to enhance heavy duty machining, precision and stability. With its excellent machine structure, you can handle heavy cutting with more ease than ever before.

• 45º slant bed construction assures solid support of turret and effi cient chip removal.

• Massive base construction combined with advanced honey comb rib reinforcement which minimises vibration while enormously upgrading structural rigidity and stability.

• The entire machine construction is heavier than competitive models for outstanding stability.

• Box ways on X and Z axes, slide way surfaces are hardened, precision ground and coated with Turcite B for maximum wear resistance.

• Extra wide slide ways on X and Z axes for increased stability during machining.

• All major structural parts are manufactured from high quality Meehanite cast iron and tempered to relieve stress for lifetime deformation free operations.

• Cs axis function is available as an option enabling turning, drilling, grooving and milling functions to be performed in one setup.
