Overview
The 670mm stroke machine tool is a specialized industrial equipment designed for machining operations that require an extended working range. With its 670mm stroke length, this machine accommodates larger workpieces than standard machine tools, making it particularly valuable in industries such as automotive, aerospace, and heavy equipment manufacturing. The extended stroke capability allows for continuous machining of longer components without repositioning, improving both precision and productivity. These machines are typically built with reinforced structures to maintain accuracy over their full working range, with precision ground ways and high-quality linear motion components to ensure consistent performance.
Structure and Working Principle
Structurally, a 670mm stroke machine tool consists of a heavy-duty base or bed, precision linear guides, a moving carriage or table, and a spindle assembly. The extended stroke is achieved through carefully engineered slideways and drive mechanisms that maintain rigidity and precision throughout the full movement range. The working principle involves the controlled linear movement of the cutting tool or workpiece along the 670mm axis, while the spindle provides rotational motion for cutting operations. Most models incorporate ball screws or rack-and-pinion drives for smooth, accurate movement, coupled with servo motors for precise positioning. Advanced models may include CNC controls for automated operation and repeatable accuracy.
Key Features
The primary feature of these machines is their extended 670mm stroke capability, which enables machining of larger components in a single setup. This reduces cumulative errors that can occur when repositioning workpieces and improves overall machining accuracy. Additional key features typically include heavy-duty construction to minimize vibration and deflection, precision ground and hardened ways for smooth movement, and thermal compensation systems to maintain accuracy during prolonged operation. Many models offer variable speed controls, automatic lubrication systems, and chip management features to enhance productivity and machine longevity.
Application Areas
670mm stroke machine tools find extensive use in industries requiring machining of large components. In automotive manufacturing, they're used for engine blocks, transmission cases, and large suspension components. Aerospace applications include wing spars, landing gear components, and structural airframe parts. Heavy equipment manufacturers utilize these machines for hydraulic cylinders, gearboxes, and large bearing housings. The extended stroke capability also makes them suitable for mold and die work, particularly for large injection molds or stamping dies used in consumer goods production.
Maintenance and Precautions
Regular maintenance is crucial for maintaining the accuracy and longevity of a 670mm stroke machine tool. Daily checks should include lubrication levels, way cover condition, and chip accumulation. Weekly maintenance should focus on checking alignment and backlash in the motion system. Precautions include never exceeding the machine's rated capacity, ensuring proper workpiece fixturing, and maintaining clean, properly tensioned drive components. The extended stroke length makes these machines particularly sensitive to thermal expansion, so maintaining consistent workshop temperatures is important for precision work.
B2B Procurement Guide
When procuring 670mm stroke machine tools for industrial use, consider both technical specifications and supplier reliability. Key evaluation points should include the machine's rigidity at full extension, positioning accuracy throughout the stroke, and spindle power at various speeds. Evaluate manufacturers based on their experience with long-stroke machines, available service network, and spare parts availability. For high-volume production, consider machines with automatic tool changers and pallet systems. Request performance guarantees and consider visiting existing customer sites to see machines in operation before making large purchases.
