ASTRA CH SERIES SLANT BED LATHES

Optimum Structural Design

Following years of research and development  Chester slant bed CNC lathes offer 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.

• 45^o slant bed construction assures solid support of turret and efficient chip removal.

• Massive base construction combined with advanced honey comb rib reinforcement minimises vibration while 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 Mehanite 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.

Quality Features Throughout Assure Greater Value

• 10/12 Position Turret

• The turret is compactly constructed and combined with bidirectional random tool selection for quick tool change.

• Tool change time is quickly accomplished in only 0.6 seconds.

• The 10 position turret accommodates 25x25mm O.D. tools and 40mm I.D. tools.

• The 12 position turret accommodates 20x20mm O.D. tools and 32mm I.D. tools.

Programmable Tail stock

• The ruggedly constructed, programmable tail stock and quill movement can be controlled on the control panel for easy setup and accurate positioning.

• Tail stock movement is driven by the turret slide.

Complete Oil Fluid Separation

• In addition to the oil fluid separation design on X and Z axes, the cutting fluid tank is specially designed with a labyrinth construction to fully exhaust the floating oil.  This assures no oil mixes with the cutting fluid.

• Double filters in the fluid tank ensure clean recirculated fluid.

Optional Tool Pre-Setter

• The tool pre-setter effectively reduces cutting tests while saving machining time.

• The mechanism is used for measuring tool diameter and length.

• The tool adjustment arm is powered and program controlled.

Optional Power Turret

• Equipped with VDI 30 power turret to ensure the most excellent machining results.

• Driven by Fanuc (L2) spindle motor.

Optional Cs Axis Function

• Cs Axis + live system, suitable for turning, drilling and milling functions.
