FAQs of Graziano Italy 3000 mm Thread Milling Machine:
Q: How does the Graziano Italy 3000 mm Thread Milling Machine operate?
A: This machine operates manually with a gearbox-controlled system, allowing users to adjust spindle speed and feed rates flexibly. The lead screw and robust gear system ensure accurate and repeatable threading across a wide range of thread pitches and lengths.
Q: What is the primary usage of this thread milling machine?
A: It is primarily used for cutting external threads on shafts and cylindrical workpieces up to 3000 mm in length. Its rigid construction and variable speed are suitable for various industrial applications, including heavy machinery manufacturing and repair.
Q: When should I use variable spindle speed during thread milling?
A: Variable spindle speed is essential when working with different materials, thread pitches, or sizes. Adjusting speed allows for optimal cutting conditions, minimizes tool wear, and enhances surface finish, ensuring precise and efficient thread production.
Q: Where can this machine be installed effectively?
A: Due to its size and approximate weight of 6500 kg, this thread milling machine is best installed in industrial workshops or manufacturing facilities with ample floor space (about 4800 mm x 1400 mm) and access to a 415V, 3-phase power supply.
Q: What is the threading process with this machine?
A: The operator mounts the workpiece using the 3-jaw chuck, sets the desired thread pitch via change gears, adjusts speeds and feeds, and then initiates the milling operation. The centralized lubrication and coolant systems assist in maintaining smooth operation and tool longevity.
Q: What benefits does a used Graziano Italy 3000 mm Thread Milling Machine offer?
A: A used model in good working condition offers robust performance at a reduced cost. Its heavy-duty build and standardized accessories ensure reliable operation for industrial threading tasks, making it a pragmatic choice for both exporters and manufacturers.
