Versatility and Precision EngineeringThe Bridgeport Series I Turret Vertical Mill stands out for its adaptable design, supporting a wide range of tasks such as precision cutting, boring, and drilling. The 45 head tilt, ram travel, and extensive longitudinal table movement allow users to address complex workpieces with accuracy, all while maintaining rigidity and smooth operation.
Designed for Robust Industrial PerformanceConstructed from high-grade cast iron and steel, this machine is built to endure heavy-duty cycles. Its table accommodates up to 340 kg, with total machine weight around 1200 kg, ensuring high stability during operations. The manual controls offer tactile feedback and fine adjustments, favored by experienced machinists for close-tolerance work.
FAQs of Bridgeport Vertical Milling machine:
Q: How do I adjust the spindle speed and feed rate on the Bridgeport Series I Vertical Milling Machine?
A: The spindle speed on this machine is variable and ranges from 60 to 4200 rpm. It is adjusted manually using controls on the head. The feed rate is also manually controlled by hand levers, letting the operator set the optimum speed and feed depending on tooling and material requirements.
Q: What type of workpieces and operations is this milling machine best suited for?
A: The Bridgeport Vertical Mill excels in precision milling, drilling, and boring applications commonly found in manufacturing and toolrooms. Its robust table supports workpieces up to 500 kg and is ideal for both single-unit prototypes and small batch production requiring manual control and versatility.
Q: When should the head tilt function be used, and what is its range?
A: The head tilt (45) enables angled machining and is typically used when cutting or drilling features that are not parallel to the table top. This adjustment is essential for producing complex geometries or when access to the workpiece requires angular positioning.
Q: Where is the best location to install the Bridgeport Series I Machine?
A: Install the machine in a spacious, level area within a workshop or manufacturing facility, ensuring there is enough room (approx. 1600 mm x 1700 mm floor space) for operator access and maintenance. Proximity to three-phase power and coolant provision is recommended for optimal operation.
Q: What is the process for routine maintenance on this milling machine?
A: Routine maintenance involves keeping the dovetail slideways clean and lubricated, checking and tightening all manual adjustment levers, and inspecting the coolant and power systems. Regular verification of spindle and table movements helps sustain accuracy and machine longevity.
Q: How does the manual control system benefit operators compared to CNC machines?
A: Manual controls provide immediate feedback and allow for real-time adjustments, making this mill suitable for skilled operators who require flexibility and tactile precision during unique or trial machining setups. This direct interaction enhances accuracy for intricate, low-volume tasks.
