Machine Design

Structural Features
of the Roeders 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

Very good visibility

due to large-sized win­dows and good acces­si­bil­i­ty to the machin­ing area from two sides; load­ing with a crane 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 RCM, 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
