The 1440 mm distance between the spindle nose and the counterspindle allows for working with even particularly long materials. The 8" ASA spindle and 94 mm bar passage offer good load capacity and remarkable versatility.

Components and Construction

The Graziano Maho GR500C Parallel Lathe features high-quality mechanical components, designed to ensure high performance and long life. The 22 kW is particularly powerful, allowing it to tackle complex machining operations effortlessly. Spindle rotation speeds, ranging from slow (155-650 rpm) to fast (600-2500 rpm), allow it to adapt to different production needs, optimizing the machining process based on the type of material and size of the workpiece.

Using the Graziano Maho GR500C Parallel Lathe

The Graziano Maho GR500C parallel lathe is a versatile machine that can be used in a wide range of industrial applications, from metalworking to plastics and other composites. Here's how to use it:

1. Workpiece preparation : Before starting, the workpiece must be secured to the chuck. Thanks to its robustness and large diameter, the lathe can handle large materials.
2. Setting the parameters : Once the workpiece is secured, the spindle speed and cutting parameters are set. The available speeds (from 155 to 2500 rpm) allow you to adapt the lathe to the job, whether you're performing slow, precise operations or performing a fast cut.
3. Turning operation : Machining begins, during which the workpiece rotates while the cutter or turning bit cuts it into the desired shape. The 22 kW allows you to tackle even the heaviest jobs without compromising speed or precision.

Maintenance and Care

Proper maintenance of the Graziano Maho GR500C lathe is essential to keep it in tip-top condition. Here are some maintenance guidelines:

• Lubrication : It is important to keep moving components, such as the cross slide and longitudinal slide, lubricated to prevent wear and improve the life of the lathe.
• Periodic Speed ​​Check : Periodically check the functionality of the spindle speeds to ensure that the lathe is always operating at its best.
• Machine Cleaning : Regularly remove machining chips and metal dust from machine surfaces. Proper cleaning helps prevent component damage and improves machining accuracy.

Safety Regulations

The Graziano Maho GR500C parallel lathe complies with the most stringent industrial safety regulations. Although it is a used machine, compliance with safety regulations is guaranteed if the machine is used correctly and maintained in good condition. It is essential:
