*Puma GT 2600L CNC horizontal lathe (general structure)
- Main control panel: on/off switch, reset, emergency buttons, etc.
- The structure – the most important component of a lathe, the component that ensures the rigidity and stability of the CNC lathe. DN Solutions has adopted a tilted, cast-iron structure for all its lathes to ensure stability and rigidity and also minimum vibration and increased precision.
- Main spindle
The basic 2-axis CNC horizontal lathe has only the main spindle. Models with (S) also have a secondary spindle (sub-spindle).
*Horizontal CNC Lathe DN Solutions – Main spindle
When we talk about the main spindle, we are primarily talking about the type of drive which can be: belt type, built-in, gear box, or direct drive.
The tailstock is the support device for the workpiece which was in the Z-axis direction. A typical tail stock structure is shown below. The tail stock cannot be attached to a machine that has a sub-spindle.
Types of tail stock
– Manual – uses human force
– Programmable – uses hydraulic pressure.
The turret is the tool holder which can be of 8, 10, 12, 16 and 24 posts, the 12 post being the most common. In principle, the turret is clamped/ unclamped by hydraulic pressure; in order to change the tools, the turret it is rotated by a servo or hydraulic motor.
*Turret of Puma SMX 2100 horizontal multi-tasking lathe
The chuck is the device that clamps the workpiece using hydraulic or pneumatic pressure and is rotated together with the workpiece by the spindle motor. The workpiece clamped in the universal will be machined by the tool attached to the turret. The chuck dimensions can vary from 6 inches to 32 inches.
The steady rest is mainly used to eliminate vibrations that are generated when the long workpiece is rotated. Steady rest can be fixed or mobile, manual or programmable.
Optional accessories that can be attached on a horizontal CNC lathe: chip conveyor, air gun, coolant gun, q-setter, part catcher, oil mist collector, oil skimmer, air conditioner, bar feeder and many more.
