The GMM Roto 150 ZW552 lathe features a design that allows for significant load capacity and flexibility when machining large workpieces. Its 16.5 kW motor provides the power needed for stability and precision even on difficult-to-machine materials like steel.

Usage Procedure

Using the GMM Roto 150 requires setting the machining parameters (rotation speed and feed) based on the size of the workpiece and the material. After securing the workpiece to the rotary table and adjusting the lateral movement bridge, the operator selects the work program and starts the cycle. Numerical or manual control allows for precise management of the turret movements, ensuring optimal cuts and finishes.

Matching accessories

Among the accessories that can be used with the GMM Roto 150 ZW552 we find:

• Self-centering chucks of various sizes
• Electronic measuring devices to ensure cutting accuracy
• Cooling kit to avoid overheating during processing
• Interchangeable carbide cutting tools for working on hard materials.

Mathematical Formulas for Optimal Use

The optimization of the machining operations on this lathe can be achieved by applying the following formulas:

• Cutting speed (Vc) : Vc=π×D×N1000Vc = \frac{\pi \times D \times N}{1000} $V$ $c$ $=$ 1000 π × D × N ​, D is the diameter of the workpiece in mm and N is the rotation speed in rpm.
• Feed per revolution (f) : this depends on the type of machining, but a common formula is f=VcNf = \frac{Vc}{N} $f$ $=$ N V c ​.
• Cutting force (F) : F=P/VcF = P / Vc $F$ $=$ $P$ $/$ $V$ $c$ , where P is the absorbed power in kW and Vc is the cutting speed.

Maintenance

Maintenance of this used lathe is essential to ensure its longevity and efficiency. Regular lubrication of the guides, checking the accuracy of the tools, and periodic inspection of the motors are essential. It's also important to monitor the coolant system and replace any worn components such as belts and gears.

Used Car Evaluation and Sectors of Use

Buying a GMM Roto 150 ZW552 is a convenient choice for those working in heavy engineering, precision machining, and the production of components for the automotive or aerospace industries. GMM's build quality, combined with the machine's robustness, means that even a used model can offer excellent performance at a significantly lower cost than a new one.

Ultimately, this lathe is an ideal choice for anyone looking for a used machine that can deliver high and reliable performance.
