Colgar FV boring and milling machines

Colgar FV boring and milling machines  

FV Series Overview

The FV series by Colgar represents a line of advanced machining centers designed for both light and fast boring and milling, alongside robust hydrostatic machines for heavy-duty applications. This series integrates extensive experience and technology with cutting-edge design software to deliver high-performance machining solutions.

Key Features:

Design and Structure:

Barycentered Structure: The FV series features a barycentered structure with a symmetric monolithic column. This design ensures stability and precision during operation.

Central Headstock: The headstock is centrally positioned and guided by two ball recirculating screws aligned along one side of the column. This alignment enhances accuracy and smoothness of movements.

Minimalist Architecture: The FV series boasts a minimalist, sober design that aligns with the modern image of Colgar. This design philosophy not only improves aesthetics but also contributes to functional efficiency.

Performance:

Linear Roller Guides: The FV series utilizes linear roller guides, which provide smooth and precise movements ideal for light and fast boring and milling operations.

Dynamic Movements: The integration of all components ensures dynamic, fast, and accurate movements, enhancing overall machine performance.

Technology Integration:

Advanced Design Software: The FV series benefits from dedicated and specific design software that optimizes the machine’s capabilities and performance.

Applications:

Light and Fast Boring and Milling: Suitable for tasks that require high speed and precision in machining.

Heavy Boring and Milling: Complemented by hydrostatic machines for more demanding applications requiring robustness and stability.

Summary:

The FV series by Colgar embodies a blend of innovative design and advanced technology, characterized by its symmetric monolithic column, precise ball recirculating screws, and linear roller guides. This series is engineered for both high-speed, accurate machining and heavy-duty operations, making it versatile and efficient for a wide range of industrial applications.

The FV series comes in an upright or T configuration. The main feature that makes the Colgar FV series a machine of the future is the structure of the two-column self-supporting upright with an incorporated base and central vertical sliding of the head carriage. The performance of these machines is the result of Colgar's know-how and continual research and development to find construction solutions worked out down to the smallest technical detail. Not only large structures subjected to FEM analysis but also large guides and many support points. The heart of the machine is the central head carriage, which has two front guides with six roller pads and two rear guides with two roller pads. Vertical movement is achieved with the exclusive design of two parallel screws positioned on the same side, one at the front and one at the rear, which also allows handling and actively compensating weight variations. In the mobile upright version, the ram has a carriage-type roller support with eight front and eight rear roller pads. In the T version, the ram is fixed but outstanding, rigid, and pyramid-shaped to ensure that the center of the table is reached both during boring with the main spindle and during milling with the accessory heads. The FV line can be configured as a milling machine or as a boring and milling machine. In the first case, tool rotation occurs with a motor-driven spindle mounted on the ram; in the second case, there is a translating spindle line in nitrided alloy steel with a two-speed range changer. The FV series, with its cutting-edge technology, allows high-performance machining of simple and complex workpieces with the best combination the market demands: speed and torque.
