360CNC ultra high speed metal band sawing machine

1、 Core technology configuration and performance advantages

1. High precision servo drive system

Servo feed technology: Compared to traditional pneumatic feed, servo drive achieves stepless adjustment of feed speed through closed-loop vector control, coupled with precision ball screw transmission, to maintain a stable cutting feed speed of 230mm/min, and the cutting surface flatness error can be controlled within 0.1mm. Especially suitable for multi specification batch production, the accuracy fluctuation during size switching is less than 0.05mm, and the yield rate is increased by more than 50% compared to hydraulic feed models.

Fully automatic feeding system: The feeding accuracy reaches 0.2mm, which meets the first level accuracy requirements of the automatic circulating band sawing machine in JB/T 4318.2-2013 standard (with a maximum allowable deviation of 0.2mm). The feeding mechanism is driven by a servo motor, with a repeat positioning accuracy of ≤ 0.08mm. When cutting 200 pieces of 45 # steel bars with a diameter of 200mm continuously, the cumulative length error does not exceed 0.2mm

2. High durability saw cutting structure

High temperature quenching saw wheel: After high-frequency quenching treatment, the surface hardness of the saw wheel reaches HRC58-62, the depth of the hardened layer is 1.5-2mm, and the wear resistance is increased by 50% compared to ordinary saw wheels. When running continuously at a line speed of 250mm/min, the radial runout of the saw wheel is ≤ 0.03mm, effectively reducing the vibration of the saw blade and extending its life to more than 1200 times (about 800 times for traditional models).

High strength variable frequency motor drive: The equipped variable frequency motor can achieve a stepless speed regulation of 200-1400 revolutions per minute, optimizing the output torque for the cutting characteristics of 45 # steel. When cutting workpieces with a diameter of 200mm, the motor load rate remains stable below 75%, saving 10% -20% energy compared to ordinary asynchronous motors. The motor is equipped with a built-in temperature monitoring module, which automatically reduces speed protection in case of overload, reducing the failure rate by 60%.

2、 Performance adaptability of 45 # steel cutting

For the cutting scenario of 45 # steel bars with a diameter of 200mm, the equipment demonstrates precise matching process advantages:

Efficiency adaptation: The parameter combination of a line speed of 250mm/min and a feed rate of 230mm/min enables single piece cutting time to be controlled within 1 minute, with an hourly production capacity of 27-33 pieces, which is 100% higher than traditional equipment of the same specifications.

Quality adaptation: 45 # steel belongs to medium carbon structural steel, which is prone to edge breakage defects during cutting. The equipment adjusts the saw blade tension in real time through a variable frequency motor, combined with the smoothness of servo feed, to achieve a cutting surface roughness of Ra1.6 μ m, which can meet general assembly requirements without subsequent polishing.

Cost adaptation: When the variable frequency motor is unloaded, it automatically reduces power by 30%. Running for 8 hours a day can save 15 kWh of electricity, with an annual energy savings of about 5400 kWh. Combined with the consumables savings brought by the extended lifespan of the saw blade, the annual cost reduction of a single device can reach more than 12000 yuan.

3、 Industry application and expanded value

1. Core applicable scenarios

Automobile manufacturing: It can be used for cutting 45 # steel transmission shafts, half shafts and other parts. The fully automated process (loading cutting unloading) realizes unmanned operation, adapting to the batch production needs of enterprises such as Dongfeng Motor. The single shift output is increased to more than 80 pieces compared to traditional equipment.

Mechanical processing: For the rough machining process of mold steel and shaft parts, the equipment supports storing 100 sets of process parameters, reducing the debugging time to less than 10 minutes when changing workpiece specifications, and is suitable for small batch production of multiple varieties.

Construction Machinery: When cutting high-strength 45 # steel components, the vibration value of the overall casting body should be ≤ 0.1mm/s to ensure that large-diameter workpieces are cut without deformation and meet the heavy-duty parts processing standards of enterprises such as XCMG Group.

2. Intelligent expansion capability

The equipment supports integration with MES system, uploading real-time data such as cutting quantity, qualification rate, equipment status, etc., to achieve digital management of the entire production process. By installing a visual recognition module, it can be extended to the positioning and cutting of irregular parts, adapting to the precision machining needs of the aerospace industry.
