Mechanical Introduction of the Billet Cutting Saw

01. Billet Cutting saw Box

The sawing box ensures precision, durability, and stability. Made from Q345-B steel with stress-relief aging, it features four bearing bores machined in one pass for accuracy. Inside, a zero-backlash gear system uses quenched alloy steel gears and hardened shafts. Imported bearings from INA, NSK, and FAG provide smooth operation and long life. A load-relief structure prevents shaft deformation, while oil cooling improves thermal control and rigidity. The zero-backlash design reduces noise and gear impact, extending bearing life and enhancing efficiency. This advanced structure benefits billet cutting saws, log saws, blank saws, and CNC cut-off saws.

Guide Mechanism of the billet cutting saw

02. The guide mechanism of the cutting saw

The guide mechanism combines a carriage, preloaded roller linear guides, and a hydraulic-assisted pressure unit for smooth cutting under heavy loads. Roller guides ensure rigidity and precise motion, while the hydraulic unit applies pressure during cutting and retracts when idle to save energy. Its optimized design aligns the auxiliary rail with the largest saw blade for efficient force transfer and protection. This structure improves accuracy, reduces wear, and extends service life. Automatic unloading further lowers energy consumption and maintenance needs.

03. The guide mechanism of the cutting saw

The machine is equipped with a powerful variable frequency motor. Through a combination of belt and gear transmission, the spindle motor drives both the spindle and saw blade at high speed, ensuring stable torque and efficient cutting performance.

04. The Slide Feeding device

The slide feed device uses a servo motor connected to a precision reducer, which drives the ball screw for smooth movement of the saw box along the bed’s guide rail. This design ensures accurate forward and backward motion, delivering precise positioning and stable cutting performance under heavy loads.

05. The Bed Base of the saw

The billet cutting saw features a robust bed with thick welded steel plates and internal ribs forming a closed-box structure. High-strength concrete inside improves rigidity and vibration damping for cutting accuracy. Stress relief ensures long-term stability. Two precision linear guideways on machined surfaces provide smooth motion, high load capacity, and reliability. This advanced design enhances performance for billet, bar, pipe cutting machines, and circular saw systems.

Billet Cutting Saw Blade Guide AND shock Absorption

06. Saw Blade Guide/Shock Absorption

The billet cutting saw uses three guiding and damping units on both sides of the blade to suppress vibration during entry and exit, ensuring smooth operation and reducing errors. These units also prevent bending vibrations from high-speed rotation, improving accuracy and extending blade life. Friction pads provide flexible support and excellent energy absorption, delivering dynamic stability and consistent performance for billet cutting saws, bar cutting machines, circular saw systems, and pipe cutting machines.

07. stable Clamping System

Each side of the saw blade has a hydraulic clamping unit with horizontal and vertical clamps plus a clamping base, ensuring multi-directional stability and precise positioning. Hydraulic actuation delivers strong force and fast response for automated cutting. An automatic separation function opens a 5 mm gap after cutting, allowing smooth blade retraction and improving cycle time and safety. This advanced design enhances performance for billet cutting saws, bar cutting machines, circular saw systems, and pipe cutting machines.

08. The Lift roller table at exit

A hydraulically controlled 140° V-type lifting roller with adjustable height supports the discharge end near the saw edge. It ensures smooth billet transfer through the clamping area, prevents collisions with fixtures, and enhances safety and material handling efficiency during cutting operations.

10. The Chip cleaning device

A micro-motor powers a rotating brush that continuously cleans the sawtooth surface during operation. This design prevents debris buildup, maintains cutting precision, and significantly extends the service life of the saw blade, ensuring consistent performance and reduced maintenance needs.

11. Servo Cut-to-Length Device

The feeding trolley is mounted on a vertically adjustable base and driven by a servo gear motor through a rack-and-pinion system for precise linear movement along guide rails. A hydraulic clamping arm secures the billet during feeding, while the lifting base prevents interference with fixtures, ensuring safe and stable operation. This advanced system delivers high positioning accuracy and smooth material handling, ideal for billet cutting saws, bar cutting machines, circular saw systems, and pipe cutting machines.
