Turn Mill Machine
Your Professional Turn Mill Machine Manufacturer!
Ningbo Jinkai Machine Tool Co., Ltd., established in 1995, initially focused on the bearing industry (Ningbo Jinshi), then transitioned into the CNC machine tool and optical equipment field (Ningbo Jinkai), and gradually developed into a comprehensive CNC machine tool enterprise (Ningbo Meinuo). By drawing on advanced machine tool technologies from Taiwan, Japan, and Germany, and combining them with the characteristics of domestic enterprises, the company has independently developed a series of CNC machine tools. Its featured products include horizontal machining centers, 5-axis machining centers, vertical lathes, and special-purpose machine tools for related industries. The company strictly implements a modern ERP management system, covering the entire process from machine tool design, production, processing, assembly technology, and quality control.

Our Service
Our company provides comprehensive pre-sales services, from technical consultation and equipment selection to solution integration and feasibility verification, helping customers accurately identify their needs and recommending the optimal equipment and configuration to ensure solutions maximize their production requirements.
Improved Efficiency
Combining turning and milling in one machine eliminates the need to transfer workpieces between machines, reducing setup times and streamlining workflows.
Enhanced Precision
Integrated machines ensure consistent alignment between turning and milling processes, minimizing errors and achieving superior accuracy.
Cost Savings
By using one multitasking machine instead of two separate machines, manufacturers save on equipment costs, floor space, and labor.
Space Optimization
Multitasking machines occupy less space than traditional setups, making them ideal for facilities with limited floor space.
Increased Flexibility
These machines can handle complex geometries, enabling manufacturers to produce intricate parts in one seamless operation.
Applications of Turn Mill Machine
Aerospace
In aerospace manufacturing, turn-mill machining centers are used for producing complex components such as turbine blades, engine casings, and structural airframe parts with precise geometries and tight tolerances.
Automotive
Turn-mill technology is applied in the automotive industry for machining transmission components, engine blocks, and chassis parts. Its ability to handle complex features and materials makes it ideal for producing critical automotive components.
Medical
Turn-mill machining centers play a crucial role in the medical sector for fabricating surgical instruments, orthopedic implants, and dental prosthetics. The precision and versatility of turn-mill technology ensure the production of high-quality medical devices with exceptional accuracy.
Energy
In the energy sector, turn-mill machines are utilized for manufacturing components for renewable energy systems, power generation equipment, and oil and gas exploration tools. These machines enable the production of intricate parts with high efficiency and reliability.
Components of Turn Mill Machine
Machine Bed: The heavy, rigid foundation (usually cast iron) that supports all components, absorbs vibrations, and ensures stability for high-precision cutting.
Main Spindle & Headstock: Located in the headstock, this rotates the workpiece at high speeds. It includes a chuck or collet for clamping and a drive motor.
Sub-Spindle (Secondary Spindle): Many turn-mill machines have a second spindle opposite the main spindle, allowing for part transfer to finish the backside without manual intervention.
Live Tooling Turret (Carriage): A rotating turret that holds not only turning tools but also driven tools (drills, end mills) for milling, drilling, and tapping operations, often referred to as live tools.
CNC Control Panel (MCU): The "brain" of the machine, which processes G-code, manages axis movements (X, Z, Y, C/B), and regulates speed/feed rates.
Axis Drives (Motors & Ball Screws): Servo motors and high-precision ball screws that provide movement for the X (diameter), Z (length), and Y (off-center milling) axes.
Coolant and Lubrication System: Delivers fluid to the cutting edge to reduce heat, improve surface finish, and lubricate moving parts, preventing thermal expansion.
Chip Conveyor/Management System: Removes the high volume of metal chips generated, preventing accumulation in the working area.
Tailstock (Optional): Provides additional support for long, slender workpieces to prevent bending or vibration, typically operated hydraulically.
