• The electrical design is in accordance with national safety standards and is equipped with, such as: emergency stop devices, limit protection, leakage and overload protection, interlocking safety devices, etc. to ensure that the whole process is safe and working smoothly.

Main Structure Of The Cutter

The lathe bed adopts honeycomb structure

---

• The bed adopts Hymson’s multi-keel structure with patent tenon & mortise welding, following the precision CNC machine tool’s design standards, through data simulation analysis and durability test, to ensure stable structure of the machine tool and long-term stable operation of the equipment;
• The lathe bed processing has undergone high temperature processing to eliminate the material’s internal stress and that produced during welding, to ensure high strength, high precision, and high tolerance.
• The middle intelligent partition is used for air extraction and dust removal, and the corresponding air outlet is automatically opened with the cutting range to reduce dust diffusion during the cutting process.

Servo Motor

---

• Branded servo motor and drive, with high encoder resolution;
• Integrating high dynamics, compact structure and energy efficiency.

Floating Cross Beam

---

• Adopting the floating cross beam structure design to offset the impact caused by the degree of reference parallelism on both sides of the machine body in long-term use, thus guarantees cutting precision;
• The floating cross beam can effectively protect the sliding block to reduce force suppression and bead blasting under force, thus guarantees the linear precision of operation and reduces the out-of-straight and out-of-round situations in cutting.

CNC Numerical Control System

Cutting Process Technology

Automatic Obstacle Avoidance

• When a workpiece cocks, the cutting head can identify it automatically and rise rapidly to avoid the obstacle and locate the position of the next workpiece intelligently
• ① To reduce the probability of collision between the cutting head and the workpiece; ② to guarantee the consistency of cutting during processing, thus improves the efficiency of processing; ③ to locate the position of the next workpiece intelligently, thus reduces the probability of integral transfer of a sheet and reduces the waste of sheets; ④ to reduce the workload of the operator and editor through the simple and intelligent operation.

• Hymson’s characteristic new technology, which improves the laser cutting production in three aspects, i.e. cutting precision, cutting speed and energy consumption in cutting
• High Efficiency: Lightning cutting has more efficient capability of perforation and faster cutting speed.
• Low Energy Consumption: The energy consumption of gas for cutting purposes is reduced by over 50%
• Good Quality: Higher quality of cutting section, smooth and even cut edge, fewer burrs.

• In case of program interruption, sudden power failure, etc. during cutting, when you restart the machine, the “Breakpoint Resume” function can memorize the path previously set and resume the processing.
• Avoid going through the process again from the original start point which is time-consuming and affects the efficiency
• When cutting a thick sheet or a workpiece with a broad outline, the “Breakpoint Resume” function can well solve a series of problems, such as time-consuming, consumption of a lot of materials, high cost, etc.

• During the real production, when a part of the sheet is not cut thoroughly due to dust on a certain node on the sheet, insufficient gas, etc., the solution for general laser cutting machine manufacturers is resetting the system interface, that is, going through the process again from the start to the end of the procedure operation which is time-consuming, consuming a lot of materials, and high-cost.
• With Hymson’s “Arbitrary Point Cut-in” function, the cutting head can cut in at arbitrary point, without cutting from the start to the end, thus solves the problems of time-consuming, consumption of a lot of materials, high cost, etc.

• A thick sheet is not cut thoroughly; lines on the section are uneven; the section has serious dross, etc. If the tool start is poor, high quality cutting effect of thick sheets cannot be obtained and a series of problems that impact the workpiece quality, such as reflection of blue light, fault, etc., may appear. In serious cases, the cutting head and optical devices may be damaged.
• With Hymson’s “Gradual Speed Regulation in Tool Start” (for thick sheets) process, after perforation, the speed regulation is gradual intelligently, thus achieves better cutting effect. This process is mainly
• used in cutting of thick stainless steel and aluminum alloy sheets, and is stable and provides high quality workpieces.

• The “Fly-cutting” process can put the start point of cutting of the outline on the tangent line of the motion trail of the laser head, without adopting leads. It does not independently cut every detail, instead, it cut all outlines into a straight line.
• It reduces the changes in the cutting direction of the laser during cutting, reduces the duration and the number of times of perforation, and ensures that the laser head is always in the high-velocity motion status during cutting, so it is very suitable for high speed cutting processing of thin steel sheets.
• It reduces the processing time of sheets and improves the cutting efficiency of the lathe.
