• Spindle with high torque and transmisson box (max 5340 Nm)
• Lower turret head is available as an option
• Turret head for axis system of tools fixation for higher cutting characteristics
• Machine bed with optmized damping features is a basis for a long life perod
• Highest accuracy at finish turning of the hardened and row parts instead of grinding
• Displayed support when starting the machine "Look and do"

Rigid construction of the machine bed:

• Solid construction of each machine allows the large machine loading
• The machine bed made of polymer concrete provides the maximum rigidity and amortization
• Linear rolling guideways provide the high rigidity and durability
• Free access to all the machine units simplifies maintenance operations
• Modular principle: all necessary changes can be applied according to your requirements

Spindle and driving system:

• Complex processing in one set-up provides the possibility of shorter processing time and lower readjustment costs
• Spindles have considerable power reserves as they are suitable for heavy processing
• High production ability and accuracy during heavy processing
• The machine is equipped with effective power-driven tools on the revolver

Working area:

• Suitable carrier location
• Possibility to use up to three tool carriers
• Additional carrier is equipped with clamping fixture against the occasional carrier displacement

Technological control:

• Automatic workpiece measuring in working area
• Workpiece measuring inside the working area with infrared data transmission system
• Workpiece measuring after processing outside the working area

Rigid turning

The machines structure is extremely stable, that allows the rigid turning without vibratons. The rigid turning is executed with wiper cutting plates made of CBN of the new generation, can also be executed on the large feed rates with excellent cutting control. At the same time special geometry of the wiper cutting edge provides excellent quality of the processed surface.

Your advantages:

• Processing with several tools
• Several operations in one set-up
• Short cycle time
• High flexibility
• Quick re-adjustment

Finish processing

Quality of the part surface (till Ra 0,10-0,15 mkm) is reached in one set-up including the preliminary turning operations, for instance for slider bearing or ball bearing.

Your advantage:

• Small expenses
• Small tact time
• One set-up instead of two set-ups

Turning process without the machining marks

It’s especially important for working surfaces of slots for sealings of hardened or row parts. You will get the quality of the part surface Ra 0,2–0,6 mkm or Rz 1–3 mkm without grinding.

Your advantage:

• Turning instead of grinding
• One set-up instead of two set-ups
• Dry processing
• Small tact time
• Small expenses
• High reliability of the technological process

Cutting and centering

Both ends of the shaft are being cut simultaneously to the appropriate size and centered by the driven tools. Part is clamped firmly. After that, turning processing within this operation is executed.

Your advantage:

• Reducing of the technological chain (only one machine is necessary instead of two machines)
• Reducing of tact time and the duration time of the manufacturing cycle

• Electric motor shaft
• Cardan shaft
• Special crankshaft
• Railway axes
• Hydraulic cylinders

Steadies

• You can choose the machine of VDF series with max. 2 steadies (CNC controlled)
• Moving independently of each other

Gear spindle

• Motor spindles or separate drives for the increased torque values are suggested (for main and counter spindle)
• Traveled counter spindle – automatic transfer of part from the main spindle for processing of the rear side of the part during the second clamping without interference of the operator
• Complex processing in one set-up provides the shorter processing time with lower expenses for re-adjustment

Integrated loading system

Automatic loading device integrated into the machine allows to load and unload the parts without opening of any loading doors.

Your advantage:

• Loading and unloading time – up to 5 seconds
• Small area is necessary.

Gantry loading

Heavy parts can be automatically loaded by the external gantry loader. The machine can be equipped at your choice by one or two loading hatches. Moving can be organized in an optimal way.

Your advantage:

• Quick loading for the high accurate serial production
• Transportation of heavy parts with large diameter of the workpiece.
