Machine Design

Structural Features
of the Röders Machines

Very rigid portal design

• Heavy, robust machine frames
• Low moving masses
• Linear and torque motors (direct drives) in all axes
• Easy instal­lation with 3‑point support

Patented frictionless weight compensation

• Constant force over the entire positioning range
• Frictionless vacuum hoses without stick-slip effect
• Optimal for highly precise drive control of the Z axis

Practice-oriented design

• Good visibility through generously dimen­sioned windows
• Good acces­si­bility to the working area from two sides
• Crane loading possible

Compact, highly rigid construction

• Linear motors in all axes for highest possible accuracy and dynamics
• No moving parts, no wear, high reliability
• Roller guideways for low friction, low heat generation and, at the same time, very high rigidity
• High-precision linear scales

Robot loading of tool changer

• Chain changers also acces­sible for automatic loading with external tools by a robot or other handling systems through a separate lift gate without inter­rupting machining

Large number of water circuits

• Machines completely tempe­rature-stabi­lised, due to a large number of water circuits
• For highest precision the guiding rails and carriages are optio­nally tempe­rature controled with a water circuit directly through the rails and carriages themselves

Axis covers

• Frictionless axis covers for best possible dynamics and accuracy

Protection against chips

• Special precau­tions taken – also during tool change sequences – in order to protect all tool holders against falling chips
