DMG MORI DMU 200P 5-axis CNC machining center

A 5-axis machining centre has the three linear axes X, Y and Z plus two rotary axes, so the tool can reach the workpiece from almost any direction. Several faces are machined in one set-up, which reduces the number of set-ups and keeps the positional accuracy between those faces. Typical parts:

• Moulds and cores with free-form surfaces

• Aerospace components and turbine blades

• Prismatic parts machined on several faces in one set-up

• Complex one-off parts and small series

ReMach lists second hand 5-axis machining centres, with travels, control, tool magazine and photos on every machine page.

Both run on a 5-axis machine, but they work differently. Knowing which one your parts need avoids paying for capability you will not use, or buying a machine that cannot do the job.

3+2 Positional Machining

• The two rotary axes tilt the part or the head to the required angle and are then clamped

• The three linear axes do the cutting

• Enough for most prismatic parts that need machining on several faces

• Lower CAM requirements and simpler programming

Simultaneous 5-Axis Machining

• All five axes move at the same time along the whole tool path

• Needed for free-form surfaces, turbine blades and continuous curved tool paths

• Requires 5-axis CAM and a post-processor matched to that exact machine and control

• In listings this is usually stated as "5-axis simultaneous machining"

A machine that supports simultaneous 5-axis machining can also run 3+2, but not every 3+2 machine can run simultaneously. When reading a listing, look for the word "simultaneous" and for the control model.

Where the two rotary axes sit determines the maximum part size and weight. This is the biggest difference between 5-axis machines.

Swivel Head with Rotary Table (B-axis in the head, C-axis in the table)

• The B-axis sits in the milling head, the C-axis is an NC rotary table

• Heavy parts stay flat on the table, only the head tilts

• Suited to large, heavy parts; this is the design of the DMG MORI DMU P series

Trunnion Table

• Both rotary axes are in the table, so the part tilts with it

• Compact and accurate for small and medium parts

• Part size and weight are limited by the table

Gantry (Portal) Design

• The spindle moves on a gantry above a fixed table

• Suited to very long or wide parts such as plates and large moulds

• Example: EDEL CP3020, table 5,000 x 2,300 mm, A-axis ±110°, C-axis ±360°

5-axis machining centres documented in the ReMach catalogue include the DMG MORI DMU P series, Reiden and EDEL. X-axis travels range from 980 mm to 3,000 mm and machine weights from approx. 16 t to 85 t.

Besides travels and spindle power, which matter on any milling machine, a 5-axis machine has a few points of its own.

Working Envelope

• Travels and table size: X, Y and Z travel together with the table dimensions

• Rotary table: diameter and maximum table load

• Swivel range: for example A-axis ±110°, B- or C-axis ±360°; it decides which tool angles you can reach

Rotary Axes and Accuracy

• NC control of both rotary axes: fully NC controlled, or only manually indexed

• In-machine measurement: tool and workpiece probing, for example a touch probe or laser system

• Kinematic calibration: after relocation, the rotary axis kinematics must be recalibrated before precision parts are run

Control and Operation

• Control and version: for example Heidenhain iTNC 530 with 3D path control

• Tool magazine and taper: number of tool positions and taper, for example SK50 to DIN 69871, or HSK

• CAM post-processor: it must match the machine and control, otherwise simultaneous 5-axis machining cannot be used

• Spindle hours: where the listing states them

5-axis machining centres weigh roughly 16 t to 85 t depending on size. Plan the following before buying:

• Foundation and hall: large machines need a foundation to the manufacturer's drawing; check the machine dimensions in the listing against floor space, hall height and crane capacity

• Dismantling and transport: in most cases the buyer is responsible for organizing the transport; upon request, ReMach can check whether transport can be arranged or supported

• Paperwork: ReMach helps with dismantling and loading, export and customs checks, and export documents

Do I need simultaneous 5-axis machining, or is 3+2 enough?

If your parts are mainly flat faces and holes on several sides, 3+2 is enough and programming is simpler. Simultaneous 5-axis machining is needed for free-form surfaces such as moulds and turbine blades, where the tool must tilt continuously along the path.

Which design should I choose: swivel head, trunnion table or gantry?

A swivel head with a rotary table suits large, heavy parts because the part does not tilt. A trunnion table is compact and accurate for small and medium parts. A gantry machine suits very long or wide parts.

Does a used 5-axis machine need recalibration after relocation?

Yes. After dismantling, transport and reinstallation, the rotary axis kinematics should be recalibrated and checked with a test part before precision work starts.

Can I keep my existing CAM programs?

Not automatically. 5-axis programming needs a CAM post-processor matched to the machine design and the control, so confirm the control and its version before buying.

How heavy is a used 5-axis machining centre and how is it transported?

In the ReMach catalogue, 5-axis machines weigh from approx. 16 t to 85 t. The machine is dismantled into assemblies and moved by heavy haulage. In most cases the buyer is responsible for organizing the transport; upon request, ReMach can check whether transport can be arranged or supported.
