China Customized Turning Machine Manufacturers and Suppliers - Bulk Turning Machine

Product Overview

The Heavy-Duty CNC Turning Machine is engineered for high-precision, continuous metal removal on shafts, discs, and complex rotational components. Built upon a rigid, one-piece Meehanite cast iron bed inclined at 30 or 45 degrees, this machine minimizes thermal distortion and absorbs high-frequency cutting vibrations during aggressive roughing operations. It is designed for machining shops, automotive Tier-1 suppliers, and aerospace component manufacturers demanding sustained dimensional stability, tight tolerances, and predictable tool life under multi-shift production schedules.

FAQ

Q: What is the standard delivery lead time for standard vs. customized CNC turning machines?

A: Standard configurations are typically dispatched within 30 to 45 days. Customized specifications or automated cell integrations require 60 to 90 days depending on engineering validation.

Q: What power supply and air pressure requirements are necessary for installation?

A: Standard power requirement is 3-phase 380V +/- 10 percent, 50/60 Hz (transformers available for custom voltages). Clean, dry compressed air supply at 0.6 - 0.8 MPa is required for hydraulic and pneumatic actuation.

Q: How do you ensure the long-term geometrical accuracy of the machine bed?

A: We use high-grade Meehanite cast iron subjected to multiple annealing and aging treatments to release internal stress, combined with precision high-frequency induction hardening on guideway surfaces.
