This article looks at everything from the way it works to the kinds of machines and software involved. You’ll also find out about the advantages, barriers, primary uses and Guidelines for selecting the right CNC for your shop.

What is Multitasking Machining?

The process of multitasking machining means a machine is designed to turn, mill and drill in one setup. Being able to use only one machine reduces setup time and increases accuracy. Traditional CNC machines can only work on one task at a time, but multitasking machines make it possible to finish multiple steps in one operation. They include spindles, turrets and advanced control systems to run smoothly. You can picture this machine by imagining a main spindle, tool magazine and control unit.

Core Components of Multitasking Machines

Main Spindle and Sub-Spindle

Cutting actions are mainly handled by the main spindle. It supports and spins your workpiece during different operations. With a sub-spindle, it’s possible to carry out secondary processes without moving the workpiece by hand. Reducing the number of setups saves your time and makes your results more reliable.

Turret & Tool Magazine

Multiple tools are in the turret, rotated and placed where they are needed. When you combine a tool magazine, you can use multiple tools in just one cycle. It lets you continue your work on complex parts without any breaks.

Y-Axis and B-Axis Capabilities

Changes you make to the Y-axis let you machine objects that are not centered on the Z-axis. Multi-axis cutting is possible along the B-axis, enabling machine tools to use intricate angles and designs. They allow you to manage complicated parts with less effort.

Automatic Tool Changer (ATC)

An ATC changes tools on its own during different operations. You don’t have to stop the machine for tool changes and you save time when working on many small batches.

Bar Feeders and Parts Catchers

Bar feeders keep giving raw material and catchers ensure that completed pieces are properly picked up. Both the robot and the system make lights-out machining possible and decrease the need for operator involvement.

Integrated Probing Systems

They measure both tool offsets and the alignment of workpieces as the machine operates. They allow you to achieve higher quality and reduce scrap when accuracy matters.

Types of Multitasking Machining

Mill-Turn Machines

A mill-turn machine allow you to mill and turn a workpiece in a single pass. You’ll notice that a spindle spins the workpiece and a milling head carries out the actual cutting of the material. It features Y-axis travel and allows live tooling, so several functions can be accomplished in only one cycle. Cylindrical parts with complex shapes are best made using these machines. You’ll spend less time setting up, achieve more accurate results and be more efficient.

Turn-Mill Machines

These machines are close to the previous type but mainly serve to complete turning tasks. The principal difference is found in how the spindle is positioned and controlled. You would use them most often when working on shaft-type parts where you make many turns but sometimes also need to mill. When you want to create exact slots, holes or flat surfaces on turned pieces, these machines are most helpful. It is easier to take care of many small steps in the process without needing to move instrument parts between machines.

5-Axis Multitasking Machines

On a 5-axis multitasking machine, you can control three linear axes as well as two rotational axes. Because of this, you can design complicated geometries all in one go. Aerospace or mold components are no challenge for these machines because they work well with undercuts, contoured areas and deep holes. Both your part quality and setup number can be improved.

Hybrid Machines

Hybrid multitasking machines are able to perform traditional machining and additive manufacturing. You can use them to make objects by stacking layers one after another. 3D printers are useful for making prototypes, fixing things and producing elaborate parts. Recent models are equipped to handle several materials simultaneously and allow you to check progress as you go.

Key Features of Multitasking Machines

Multiple Spindles and Turrets

The main and sub-spindles, together with several turrets, are typical features on these machines. You don’t need to move the part between machines for turning, milling or drilling. With this system, handling is reduced and results become more accurate.

Live Tooling

With live tooling in place, you don’t have to pause the spindle to carry out drilling or milling operations. You can do these actions with the part in motion, cutting down on the time it takes and making setup simpler.

Sub-Spindles

The sub-spindle makes it possible to perform work on both ends of your part at the same time. This helps you save time because you don’t have to move parts by hand and you also get better alignment for more complex parts.

Tool Changers and Automatic Tool Indexing

With such systems, you can easily change tools and keep working automatically. You keep your work moving and reduce the time needed for changing tools.

Integrated Metrology Systems

On-machine probing ensures you can measure and fix any issues in dimensions quickly. You are able to use all your materials and keep parts consistent in quality.

Thermal Compensation and Stability

High temperatures can modify the parts of an aircraft. Thanks to thermal compensation, the machine can handle temperature changes by itself. Whether you are carrying out operations at pace or not, your results are always accurate.
