The CNC Turnmill machine explained

The evolution of manufacturing: Unlocking complex geometric shapes with CNC turntables

In order to unremittingly pursue the efficiency and accuracy of modern manufacturing, the functions of computer numerical control (CNC) machines continue to push boundaries. Milling centers use rotating tools and lathes to shape materials with fixed tools to rotate materials, but the complex components of real game changes are CNC Transfer MachineSometimes called Mill Center. This powerful man overcomes the inherent limitations of single-process machines and integrates turn and Milling function in a single complex setup. At Greatlight, as experts in advanced five-axis CNC machining, we use these multi-functional machines every day to solve complex metal parts that originally required multiple settings and machines to provide unparalleled advantages in accuracy, efficiency and complexity.

Understanding the Transfer Machine: The Best of Both Worlds

Fundamentally, the CNC Turnmill machine combines the rotational function of the CNC lathe (turn) with the multi-functional multi-axis motion of the milling machine. The workpiece is fixed to the rotating spindle (such as a lathe), but crucially, the machine also has real-time tooling capabilities. This means that the tool mounted in the turret (or tool changer) can be rotated independently, while the workpiece either rotates (for rotational operations) or stays stationary (for milling, drilling, hitting, etc.). The machine control unit coordinates these movements simultaneously or sequentially with incredible accuracy.

Some key components define rotary ore:

1. Spindle: Hold and rotate the main workpiece (turning shaft – usually C-axis).
2. Subspindle (on many models): Located opposite the main spindle, allowing seamless transfer of parts between spindles between spindles for complete machining in a single cycle ("One-to-one"). This allows for backside operation without manual intervention.
3. Real-time Tool Turret/Tool Changeer: Accommodate a variety of tools that can be active Rotate. These tools are driven by their own spindles, allowing milling cutters, drills, faucets, and even bragging tools to operate on rotating or fixed workpieces.
4. Multi-axis motion: In addition to primary rotations (X, Z, C), advanced rotations combine Y-axis motion (allowing the tool to move perpendicular to the spindle centerline), and even secondary rotation axes (e.g., B-axis on the milling head) – jumping them into a full 5-axis turning area. This multi-axis function is where magic happens in complex parts.
5. CNC control system: Complex brains often have advanced software that interprets G-code instructions and coordinates all these complex movements and tool changes.

Why choose a transfer? Revealing the striking advantages

From individual milling and turning operations into turning centers brings transformative benefits:

1. Significantly reduce cycle time and improve efficiency: Eliminating the need to move parts between machines saves a lot of time. this "One-to-one" The principle minimizes settings changes and processing. Complex parts can be made in fewer steps.
2. Enhanced accuracy and dimensional consistency: By completing multiple operations in a single setup (or transferring between coordinated spindles), the tolerance stack that occurs during the second computing part is effectively eliminated. This ensures excellent position accuracy and tighter tolerances. At Greatlight, we consistently achieve microscopic level of accuracy using advanced 5-axis conversion devices.
3. Complex geometric shapes make it simple: This is the core force. The ability to perform rotational and linear tool path movements, especially the ability to have a 5-axis function on the milling side, allows for the machining of complex profiles, non-intermediate features, undercuts, asymmetric geometry as well as intervertebral discs, complex curves on the axis, and more expensive (impossible or more expensive geological processes).
4. Reduce waste and increase production: Fewer settings translate directly to reduce potential damage between processing errors and operations. Enhanced accuracy minimizes tolerances due to changes in settings.
5. Reduce operating costs (per part): While initial machine investment is large, a substantial reduction in cycle time, labor costs associated with setup/operation/processing, floor space requirements and fixed costs can lead to a reduction in total cost per part for complex components. Automation potential is also higher.
6. Material versatility: High-performance turntable centers handle a wide range of materials – from common alloys such as aluminum and stainless steel to exotic metals such as titanium, inconel and hardened tool steel are crucial for aerospace and medical applications. Greatlight specializes in custom processing of most metal materials.

FAQ: CNC Turnmill Machine

1. Q: What is the difference between a CNC lathe and a CNC Turnmill machine?
   one: CNC lathes mainly perform rotational operations (turning), and the workpiece rotates to target the fixing tool. CNC Turnmill added "Real-time tools" – Rotary milling spindle on turret. This allows it to rotate or Fixed workpieces in the same machine envelope can be extended with fewer settings.

2. Q: What’s there "One-to-one" What does it mean?
   one: "One-to-one" Refers to the ability of advanced rotary machines (especially one with sub-spindles and real-time tools) to machining all necessary functions on the part in a single setup cycle. The sub-spindle grabs the part, back of the machine after it is finished on the first side, and pops up the finished part – eliminating the need for any auxiliary machining setup on other machines.

3. Q: What are the advantages of 5-axis at the turn?
   one: The true 5-axis milling capability (interpolated along 3 linear axes and 2 rotation axes interpolated) greatly increases the complexity of the geometry it can create. It allows milling of complex contours and features at composite angles on rotating workpieces without repositioning, accessing previously unreachable areas, and achieving higher accuracy on complex surfaces – all in a single setup.

4. Q: Are Turnmill machines only suitable for very complex large-volume parts?
   one: While very beneficial for highly complex parts, the increased efficiency (setting time/processing time is reduced) and the accuracy advantages of Turnmills also make them increasingly feasible, even for medium-sized volume and batch production. They are especially advantageous when the parts have cylindrical and prismatic (off-axis) features that require precise relationships.

5. Q: Which materials can be used with Turnmill Technology Greatlight Machine?
   one: GREATLIGHT has extensive expertise to process a wide range of metals: aluminum and alloys, stainless steel (300 and 400 series), tool steel, alloy steel, titanium, copper, brass, bronze, Inconel®, Hastelloy® and more. We customize tools, speed, feeding and coolant strategies based on the best results for each material.

6. Q: In addition to main processing, what other completion services can be provided well?
   one: We offer a comprehensive one-stop post-treatment solution including precision grinding/grinding, complex engraving, heat treatment (hardening, pressure relief), surface treatment (anodizing, plating, painting, painting, paint, passivation), assembly and rigorous inspection/measurement (CMM, surface roughness measurement). You can manage the entire project seamlessly with us.
