Hey guys, this is Amanda from OMNI. OMNI is the leading large cnc router manufacturer in China. We mainly offer all kinds of customized cnc router design solution, including 3 axis, 4 axis and 5 axis cnc router. Manufacturer of CNC Router China, CNC Knife & Plasma Machines

Recent month, there is one client would like us to design 16M length ( Y Axis) 5 axis cnc router machine.

Here is the requirements from client:

1. Travelling size: X 3600mm , Y 8500mm or 16000mm, Z 1500mm.
2. Travelling Precision: 0.2mm
3. Material to process: wood panel, polystyrene, PU, Laminboard.

Till now, we offered 3 kinds of machine frame design, and the client offered No. 3 design. But no one have been satisfied by both sides. So we would like to post here to see more professional opinion on these design.

Design 1:

Attachment 431306

Ballscrew transmission on Y axis. The advantage is ballscrew is with higher precision. But when ball screw is with 8500mm size, the machine frame has to be 17,000mm on Y axis. If change to 16000mm for ball screw, the machine frame has to be 32000mm. The client's workshop can not park it.

Design 2:

Attachment 431308

Rack and pinion on Y axis, gantry support is fixed.

This design ensure the machine runs at higher speed, higher precision, the machine frame is also sturdy.

But the working table is lower as client expected, and it is not convenient for material loading. The cost of whole machine is also higher.

Design 3:

Attachment 431310

This design is offered by the client. According to this design, the cost of machine frame is lower and it is not as heavy as other designs. But may occur deformed, precision also is low.

Design 4:

Attachment 431312

This design is friendly for workpiece loading, but the gantry support is too high: 2000mm. It is with high requirements to linear guide, motor, reducer, and machine working speed is also low, easily cause vibrication.

A 16000mm Y axis 5 axis design is always complicated. So we would like to post here to get your opinion and suggestions. Which design you prefer or what suggestion do you offer?
