Carriage Body/Frame for Cutting Tool Carriages

Product Specifications

Technical details and manufacturing context for Carriage Body/Frame

Definition

The carriage body/frame is the main structural component of a cutting tool carriage, providing rigid support for mounting cutting tools, guiding mechanisms, and drive components. It ensures precise positioning and stability during machining operations by maintaining alignment and absorbing cutting forces. Typically manufactured from cast iron, steel alloy, or aluminum alloy, the carriage body/frame is designed to withstand static and dynamic loads while minimizing deflection and vibration. Its dimensions—width, length, and height—are specified in ranges (e.g., width 200–600 mm, length 400–1200 mm, height 150–400 mm) to accommodate various machine tool configurations and tooling systems. The maximum load capacity ranges from 500 to 3000 kg, beyond which excessive deflection and chatter may occur. Positioning accuracy and repeatability are critical parameters, typically within ±0.01–±0.05 mm and ±0.005–±0.02 mm respectively, as per ISO 230-2. Operating temperature range is -10 to 60 °C, and ingress protection is rated IP54–IP65 per IEC 60529. Material grades such as HT250–QT500 (per GB/T 9439 and GB/T 1348) and surface hardness HB180–HB280 (per ISO 6506-1) influence damping and wear resistance. The weight of the carriage body/frame ranges from 50 to 300 kg, affecting inertia and machine dynamics. These values are reference ranges for directory purposes; actual specifications must be confirmed with the legal manufacturer or supplier for specific models and applications. Standards listed are procurement references and do not imply certification or compliance of any particular product.

Working Principle

The carriage body/frame serves as a stable platform that moves along machine axes (typically X, Y, or Z). It transfers motion from drive systems to cutting tools while maintaining structural integrity against cutting forces, vibrations, and thermal expansion to ensure machining accuracy. The body/frame is designed to absorb and distribute forces, preventing deflection that could compromise tool positioning. Its rigidity and damping characteristics are critical for maintaining alignment under load. The moving platform's mass and stiffness influence dynamic behavior, affecting machining stability and surface finish. Proper thermal management and lubrication are necessary to maintain consistent performance across the operating temperature range.

Frequently Asked Questions

What materials are commonly used for carriage bodies/frames?

Common materials include cast iron, steel alloy, and aluminum alloy. The choice affects rigidity, damping, and weight. Material grades such as HT250–QT500 are referenced in standards like GB/T 9439 and GB/T 1348, but actual selection depends on application requirements.

What are the typical dimensions and load capacities?

Reference ranges are: width 200–600 mm, length 400–1200 mm, height 150–400 mm, and maximum load capacity 500–3000 kg. These are directory ranges; exact values must be confirmed with the manufacturer for a specific model.

How is positioning accuracy and repeatability specified?

Positioning accuracy is typically ±0.01–±0.05 mm and repeatability ±0.005–±0.02 mm, per ISO 230-2. These are reference values; actual performance depends on the machine assembly and calibration.

What standards apply to ingress protection and surface hardness?

Ingress protection is rated IP54–IP65 per IEC 60529, indicating protection against dust and water. Surface hardness is specified as HB180–HB280 per ISO 6506-1. These standards are references for verification; compliance must be confirmed with the supplier.
