Precision Engineering and Build QualityThis TOS heavy duty lathe offers exceptional precision and durability thanks to its precision-ground bed ways and robust cast iron construction. High rigidity ensures minimal vibrations, allowing for accurate and consistent performance, even under demanding workloads. The lathe's 600 mm bed width and 800 mm maximum swing diameter accommodate a wide range of workpiece sizes, making it suitable for both industrial and workshop environments.
Advanced Usability and VersatilityDesigned with operator convenience in mind, the machine comes with a manual control system, an easy-to-use coolant system, and both manual and centralized lubrication options. The spindle is compatible with an MT6 taper, and the chuck options enable flexible work holding for various operations. With thread pitch capabilities from 0.5 to 20 mm (metric) and 2 to 40 TPI (inch), it serves diverse threading needs efficiently.
Powerful Performance and CapacityEquipped with a 7.5 kW main motor, this lathe delivers consistent high-torque performance for even the most demanding applications. The machine handles workpieces up to 3500 mm between centers, and the variable speed control (30-1500 RPM) allows for precise machining of a variety of materials and thicknesses, including cuts up to 50 mm. Its weight of approximately 4500 kg and overall dimensions denote its capacity for industrial-grade operations.
FAQ's of TOS 3500 mm Heavy Duty Lathe Machine:
Q: How does the TOS 3500 mm Heavy Duty Lathe Machine enhance machining precision?
A: The lathe is engineered with precision ground bed ways and a robust cast iron body, which lend high rigidity and minimize vibrations during operations. This stable platform, coupled with a wide bed and centralized or manual lubrication system, ensures smooth and precise machining-ideal for heavy-duty, high-accuracy tasks.
Q: What types of workpieces and operations is this lathe suitable for?
A: With a distance between centers of 3500 mm, a max swing diameter of 800 mm, and support for both metric and inch thread pitches, this lathe is excellent for turning large shafts, rollers, and long cylindrical parts. Its capability to handle up to 50 mm cutting thickness and variable speeds accommodates a wide range of metals and machining processes including threading, facing, and grooving.
Q: When should the centralized lubrication system be used over manual lubrication?
A: The centralized lubrication system is ideal for continuous or long-duration operations, as it ensures consistent lubrication to all critical components, reducing wear and maintenance needs. Manual lubrication may suit smaller workshops or shorter tasks where effortless, periodic hand lubrication is sufficient.
Q: Where is this lathe typically installed and what are the installation requirements?
A: This lathe is often used in industrial settings like manufacturing plants, tool rooms, and heavy machine shops. Installation requires a solid, leveled foundation capable of bearing the machine's approximate weight of 4500 kg and access to a 415 V, 3-phase, 50 Hz power supply.
Q: What is the process for changing the chuck or accommodating different tool sizes?
A: The lathe accommodates both 3-jaw and 4-jaw chucks, allowing for flexible work holding. Changing the chuck involves disengaging the spindle and securing the new chuck in place; tool posts can handle tools up to 32 mm x 32 mm, which can be quickly swapped as needed for various operations.
Q: How does the variable speed control benefit machining operations?
A: The variable speed range (30-1500 RPM) allows operators to match the cutting speed to material type and operation, helping optimize surface finish, tool life, and production efficiency. This flexibility makes the lathe adaptable to numerous machining and finishing tasks.
