Heavy-Duty Construction for Precision MetalworkingThe FA4AV features a rigid, cast iron and steel design for exceptional vibration resistance and machining stability. Hardened and ground table slideways ensure smooth movement and long-term accuracy even under the heaviest loads. Designed for reliability, this machine is ideal for precision milling applications in engineering workshops, production lines, and tool rooms.
Versatile Manual Controls and Semi-Automatic FeedsEquipped with manual and power feeds, the FA4AV enables operators to select the optimal approach for any job. Longitudinal, cross, and vertical travel can be adjusted using manual wheels or engaged in rapid/semi-automatic modes, ensuring flexibility in operation. The user-friendly, manual control system makes it easy to handle complex workpieces and adapt to diverse machining tasks.
Efficient Performance for Varied WorkpiecesWith a large table (1600x400 mm) featuring five T-slot clamps and a 700 kg load capacity, the FA4AV can secure sizable and heavy parts with ease. Its spindle, rotatable in both directions, broad speed range, and ISO 50 taper acceptance accommodate numerous tool holders, making it suitable for milling, drilling, and boring a variety of materials, from soft metals to hardened steel.
FAQs of TOS FA4AV Vertical Milling machine:
Q: How do I operate the power feed and rapid feed functions on the TOS FA4AV milling machine?
A: The FA4AV offers both manual and semi-automatic (power) feed options. For standard feeding, use the handwheels on the longitudinal, cross, or vertical axes. To engage power feeds or rapid traverse, select the desired feed rate using the control levers and activate the feed buttons. This enables efficient movement of the table for rough positioning or high-speed approach.
Q: What materials can the TOS FA4AV effectively mill?
A: Thanks to its rigid construction, heavy-duty table, and high-power spindle, the FA4AV is suitable for machining a wide array of materials, including steel, cast iron, non-ferrous metals, and harder alloys. The versatile speed range and reliable power feed system support precision work in metalworking and design industries.
Q: When should I use the coolant and central lubrication systems on this machine?
A: The coolant system, powered by an integrated electric pump, should be used during most metal cutting operations to reduce heat and prolong tool life. Always ensure coolant is circulating before starting high-speed or deep-cut jobs. The centralized lubrication system keeps critical moving parts properly oiled; check oil levels and cycle the lubrication before each shift for optimal machine health.
Q: Where is the TOS FA4AV commonly installed and used?
A: The FA4AV is frequently installed in industrial machine shops, fabrication workshops, tool rooms, and manufacturing plants. Its large floor footprint and capacity for up to 700 kg table load make it ideal for environments that require robust, precision metalwork, particularly with medium to large components.
Q: What are the benefits of the ISO 50 spindle taper and gear-driven transmission?
A: An ISO 50 spindle taper allows the use of a wide range of robust tool holders and accommodates heavy-duty cutting tools. The gear-driven transmission provides consistent torque across eighteen spindle speeds (561800 RPM), supporting both low-speed torque for tough materials and high-speed finishing operations.
Q: How do I change the spindle speed or direction on the FA4AV?
A: Spindle speed is selected via a gear shift lever, allowing you to choose from 18 different speeds to match your tooling and material requirements. The machine supports both clockwise and counterclockwise spindle rotation, which can be switched using the spindle direction control for flexible machining applications.
