It is the preferred equipment for high-density warehousing scenarios. The product integrates precision machinery, transmission technology, and guidance technology, and is characterized by stable expansion and contraction, accurate positioning, and strong load bearing. It is widely used in various automated three-dimensional warehouses, intelligent logistics distribution centers, and is suitable for telescopic fork matching, stacker operation, and other scenarios. It can be customized according to the actual needs of customers to meet different load, stroke, and installation size requirements, providing efficient and reliable cargo transfer solutions for high-density warehousing.
Structure and section
Cross section: narrow top and wide T shape, top guide surface, bottom wide support surface, guide edges on both sides
type
T-shaped guide: convex T on the bed, concave T on the slide
Inverted T-shaped guide rail: concave T on the bed body, convex T on the sliding table (commonly used for heavy loads)
T-slot guide: working surface with T-slot, T-bolt can fix workpiece/fixture
Materials and processes
Cast iron: HT250/HT300 gray cast iron, QT500/QT600 ductile iron (good vibration absorption, low cost)
Inlaid steel rail: 45 steel/GCr15/CrWMn hardened (HRC58 - 62), extremely wear-resistant
Heat treatment: surface quenching, intermediate frequency quenching, quenching and tempering, stress relief aging
Machining: milling/grinding/scraping, flatness ≤ 0.005mm/m, groove tolerance ± 0.01mm
III. Core features
Ultra-high rigidity: T-shaped cross-section flexural/torsional strength, no deformation under heavy load
Heavy load capacity: 5 - 50t single load, suitable for heavy cutting/large workpieces
Anti-overturning: wide bottom support, small rollover moment, high stability
Good damping: excellent damping of cast iron, cutting vibration reduction, smooth processing surface
Easy to fix: T-slot can be quickly clamped, suitable for tooling/fixtures
Disadvantages: High friction (μ = 0.05 - 0.15), easy to crawl at low speeds, limited speed
IV. Performance parameters
Load capacity: 5 - 50t (higher customization)
Straightness: precision grade ≤ 0.005mm/m, ordinary ≤ 0.02mm/m
Surface hardness: cast iron HB180 - 240; inlaid steel HRC55 - 62
Coefficient of friction: 0.05 - 0.15 (sliding); Plastic 0.03 - 0.05
Adaptation speed: ≤ 10m/min (heavy load); ≤ 20m/min (light load)
V. Typical applications
Heavy machine tools: gantry milling/planing, floor boring, vertical lathe, heavy machining center
Workbench: T-slot workbench, assembly platform, welding tooling
Large equipment: presses, injection molding machines, metallurgical equipment, wind power equipment
Ground guide: heavy-duty conveyor line, stacker, heavy-duty AGV
Six, selection points
Load: 5t/10t/20t/30t + → Select section size and material
Accuracy: precision (≤ 0.005mm/m) scraping/grinding; ordinary milling
Speed: choose T-shaped for low speed and heavy load; choose rolling guide for high speed
Environment: high temperature/dust choose cast iron/inlaid steel; clean choose stainless steel/coating
Fixed: need to clamp and select T-shaped groove; pure guide light selection T-shaped
Seven, compare with other guides
VS rectangular guide rail: T-shaped stronger anti-overturning, more stable guide, easy installation and positioning; larger rectangular bearing surface
VS dovetail guide: T-shaped rigidity/stronger heavy load, simple processing; adjustable dovetail clearance, suitable for mobile workbench
VS rolling guide: T-shaped rigidity/anti-vibration/heavy load far superior; low rolling friction, high speed and high precision
