China Turn‑Mill Machine Machine Manufacturers Suppliers Factory - Customized Service

Product Overview

The Turn-Mill Machine integrates multi-axis turning and high-speed milling capabilities onto a single platform. Designed for complex prismatic and rotational components, this machine eliminates secondary setups, reduces tolerance stack-up, and cuts overall cycle times for high-mix, high-precision production environments.
Constructed on a heavily ribbed, one-piece Meehanite cast iron bed, it delivers the structural rigidity required for heavy roughing and ultra-smooth finishing of aerospace alloys, hardened steels, and non-ferrous metals.

FAQ

Q: What is the primary advantage of this turn-mill machine over a traditional lathe and vertical machining center combination?

A: Integrating turning and milling in one machine eliminates transfer errors between separate setups. It reduces part handling time, cuts floor space requirements significantly, and ensures strict concentricity between turned diameters and off-center milled features.

Q: How does the machine maintain accuracy during extended, multi-hour production runs?

A: Dimensional stability is maintained through a combination of a thermally symmetrical Meehanite cast iron bed, chilled fluid circulation around the spindle and ball screws, and real-time software thermal compensation that actively adjusts axis positions based on temperature feedback.

Q: What types of CAD/CAM software are compatible with the multi-axis milling and sub-spindle transfer functions?

A: The machine controller natively processes standard G-code generated by mainstream CAM software packages, provided correct post-processors for C-axis, Y-axis, and sub-spindle synchronized pick-off are utilized.

Q: Can this machine handle difficult-to-cut materials like titanium and high-temperature alloys?

A: Yes. The rigid 45 degree slant bed, high-torque geared headstock options, and high-pressure coolant delivery systems provide the necessary chip breaking and thermal dissipation required for stable alloy machining.

Q: What are the specific electrical, pneumatic, and foundation requirements for installation?

A: Standard power requirements are 3-phase, 380V/415V, 50Hz/60Hz with an appropriately rated transformer. Pneumatic supply requires dry, filtered air at standard industrial pressure. A reinforced concrete foundation of adequate thickness is recommended to isolate external vibrations.

Q: What is the standard warranty coverage and availability of replacement parts for overseas buyers?

A: The machine carries a standard warranty covering all mechanical and electrical defects. Critical spare parts—including spindle cartridges, servo drives, and ball screws—are maintained in inventory to guarantee rapid dispatch and minimize operational downtime.
