Rail Saw
Rail Saw - K1270 Internal‑Combustion Abrasive Rail Cutting Machine
The K1270 rail saw is portable gasoline‑powered abrasive cutting equipment specially built for railway track work. It is compatible with steel rails ranging from 43kg/m to 75kg/m, delivering cut surfaces fully compliant with international railway industry standards. As essential field equipment, it is widely deployed for railway overhaul, routine track maintenance, rail replacement and emergency rush‑repair operations. This rail cutter features rapid cutting speed, high grinding disc service life, precise cut section, lightweight construction, easy mobility and reliable operational safety for diverse track‑site conditions.
Working Principle & Basic Structure
Working Principle
Adopting toothless abrasive saw cutting principle. Driven by the swing mechanism, the high‑speed rotating grinding wheel swings reciprocally along a set orbit around the rail axis to perform rail cutting work. This design shortens the contact length between grinding‑wheel plane and rail cross‑section, effectively lowering abrasive disc wear and improving disc utilization rate plus overall working efficiency.
Primary rotary motion: The gasoline engine transfers power via clutch and V‑belt to drive the main spindle and cutting disc.
Feed cutting motion: Cutting feed is realized by relative tilting movement of cutting arm and swing arm, assisted by the machine's self‑weight.
Basic Structure
Rolling friction pairs reduce component abrasion and extend total service life.
Swing arm, cutting arm and belt pulley adopt cast aluminium alloy construction: light weight while maintaining high structural strength.
Robust clamping mechanism with anti‑derail safety function. The machine's centre‑of‑gravity aligns precisely with rail central axis; even under minor clamping loosening, the unit will not jump off the rail during cutting.
Separate cast‑aluminium engine base, lightweight for manual handling.
Auxiliary travelling support wheels fitted, enabling smooth moving on ground and track surfaces.

Core Advantages of Ustyle K1270 Rail Saw
Broad Rail Compatibility: Handles standard rails from 43 kg/m up to heavy‑duty 75 kg/m rail, fits most common global track profiles.
Fast Cutting & Disc Economy: Completes 60kg/m rail cut within 120 seconds; optimised swing cutting reduces disc consumption and raises disc service cycles.
High‑precision Cutting Surface: Neat, low‑distortion cut cross‑section, meets railway acceptance criteria, minimal secondary finishing required.
Anti‑derail Safety‑oriented Design: Gravity‑aligned clamping fixture prevents derailment risk during field cutting operations.
Light‑Weight Aluminium Alloy Frame: Key structural parts use cast aluminium alloy; total weight only 28 kg, easy for two‑person carry and track relocation.
Self‑powered Field Operation: Internal‑combustion drive, no external power source required; perfect for remote sections, new‑line construction and emergency repair sites without grid power.
Good Maneuverability: Auxiliary travelling wheels allow smooth movement on ground and track; simple assembly, easy on‑track deployment.
Certified Quality: ISO9001 and CE certified, stable performance, convenient spare‑parts replacement for overseas project use.

Frequently Asked Questions (FAQ)
Q1: What rail weight grades can the K1270 rail saw cut? A: It is designed for 43 kg/m ~ 75 kg/m steel rails, covering most standard heavy‑haul and common‑speed railway rail specifications.
Q2: Does this rail saw require external power supply? A: No. K1270 is gasoline‑driven internal‑combustion rail cutter. It works fully independently for remote track‑site operations without mains power.
Q3: What is the service life of the standard abrasive cutting disc? A: Under standard operating conditions, one disc can complete ≥4 cuts for 50 kg/m rail, ≥3 cuts for 60 kg/m rail. Actual service life is affected by rail hardness, operator skill and cooling condition.
Q4: What is your warranty policy for rail saw equipment? A: We offer a 12‑month warranty for main engine and structural assemblies. Consumable parts such as cutting discs, V‑belts, spark plugs are not covered by warranty; related spare parts can be supplied separately.
Q5: Can you supply OEM service for rail saws? A: Yes. OEM branding, custom paint colour and partial configuration adjustments are available for bulk railway project clients.
Q6: Do you provide English‑language operation manuals and after‑sales technical guidance? A: Each unit comes with English‑version operation & maintenance manual. Operation guidance videos and online technical support are provided for overseas customers.
