With the rapid development, the cycle is constantly shortened, requirements on welding automation and quality is further improved. As cutting quality directly affects the welding quality and welding automation, in order to meet the soaring demands, our company specially researched and developed the plasma rotary chamfering tools mainly used for cutting fixed and V-shaped groove, and compensating cutting angle. The guiding ideology of the design: improving the degree of automation, reducing the labor intensity and improving the cutting efficiency under the premise of ensuring the level cutting quality.
The beam is wide-body box welded structure with good rigidity, high strength, high reliability; no guiding surface is not finely polished by precise machine to ensure each moving body on the right position. Heavy-duty frame and the beam with sufficient strength can completely meet the acceleration ≥ 0.6m/s impact requirement.
Symmetry treatment of both-sides drive on two frame end with balancing gravity center to maintain dynamic balance effectively.
The CNC cutting machines manufactured by our company are of gantry structure. The most important parts of gantry frame is beam and end frame. The beam is equipped with transverse rail and precise gear. During actual cutting course, beam is served as the base platform of torch tackle to ensure the rigidity of beam in the terms of performance and without deformation. However, the beam is an integral welded structure. In each side parts, it is inevitable to forming many stresses, which will be gradually released out and cause beam deformation. If that happened, the foundation of ensuring the cutting precision will be torn down and the deviation is non-compensable, even lead to scrapped, so, the stress must completely relief out through overall annealing treatment, ensuring the beam and end frame no deformation forever.
All CNC cutting machine manufactured by our company will be carried out annealing treatment to relief the welding stress to prevent the structure deformation, we hope customer came to our company for a on-site visit.
The longitudinal guiding rail is made by 32KG high-strength rail steel, the top and side surfaces are through finely grinding treatment, transverse guiding rail is made by imported cold-drawn profiles, both the sides of guiding rail are equipped with precise gears.
Strength: Not less than 700N/ mm²; weight per meter not less than 10T, tensile strength of rails itself not less than 883MPa and compressive strength not less than 1000T.
Processing Method: grinding through high-precision rail grinding machine
Rail production accuracy: parallelism between gear installation reference plane and the guide side plane is less than or equal to 0.02mm. size deviation of two sides of main rail is less than or equal to ±0.02mm, the verticality error between two sides of main rail and top plane is less than or equal to ±0.02mm
As for rail installment method, refers to the concrete foundation drawings or “I”-beams drawing provided for customers.
The longitudinal gears are made by high-precision machines.
Production accuracy of longitudinal gear: 7-grade
Longitudinal racks are equipped with pitch racks. Since the distance between the revolutions of the CP gears is an integer, this greatly reduces the cumulative error of the machine, especially the one with longer rails.
Electromagnetic Central Air Distribution System
The installation of rail and gear rack clearance error main depend on the machining accuracy of one-single rail, our company’s rail machining accuracy to ensure all the flatness are 0.02mm, During connecting installation, we fix two ends of rail with steel wire, through adjusting the bottom plate to amend the rail error; the segmental rails are connected together through tight rod, so as to ensure the cooperation between the guide rails.
Both ends of the longitudinal rails have electrical limit switches, and a mechanical stopper with a rubber pad is provided to ensure that they are protected against collision in the event of electrical control failure.
When installing the machine rail, The height of the guide rail shall be lower than the height of the cutting table to ensure easy loading and cutting.
All gas path by the central valve system centralized control, equipped with the solenoid valve, control valve, continuous pulse automatic ignition, easy to achieve artificial intelligence control. Oxygen or gas can be fed from the left or right side of the central airway, through the appropriate diameter of the pipeline transmission, the central valve system using a solenoid valve to control the air flow and through the pressure regulator adjusting the flowing air pressure.
The pressure gauge and the control valve are installed above the central control panel, so that the operator adjusts and inspects the gas pressure in the best condition at the time of cutting. On the panel is equipped with a switch adjusting solenoid valve, which can be manually adjusted and automatically controlled by the CNC system control.

Servo Reducer: (Taiwan Humphrey)
Reduction ratio: input speed ratio on the output speed.
Series: Number of planetary gears. As a set of planetary gears can not meet the larger transmission ratio, sometimes need two sets or three sets to meet the user requirements for larger transmission ratio. As the number of planetary gears is increased, the length of the two or three deceleration stages will increase and the efficiency will decrease.
Full load efficiency: refers to the maximum load conditions (failure to stop the output torque), reducer transmission efficiency.
Average life: refers to the reducer in the rated load, the continuous working hours at maximum speed.
Rated torque: a standard for the reducer. At this value, the life of the gear unit is the average life when the output speed is 100 rpm. Beyond this value, the average life of the reducer will be reduced. When the output torque exceeds twice the value, the gearbox is faulty.
Lubrication method: no lubrication. The reducer is fully sealed, so there is no need to add grease for the whole period of use.
Noise: The unit is in decibels (dB). This value is measured when the input speed is 3000 rpm, without load, one meter distance from the reducer.
Return stroke gap: the output is fixed, the input clockwise and counterclockwise rotation, the output torque generated by the rated torque + -2% torque, the reducer input has a small angular displacement, the angular displacement is the return gap. Unit is “points”, that is, one of the sixty. The usual return stroke gap value refers to the output end of the reducer.
Adjusting Arc Voltage (HP201)
- Arc voltage height controller for desktop or gantry CNC plasma cutting machines
- Plasma arc voltage height controller uses some plasma power supply with constant current characteristics, in the cutting process, the cutting current is always equal to the set current, and cutting arc voltage changes with the height of the torch and plate at a fixed speed, when the height of the torch and the plate increases, the arc voltage rises; when the height of the torch and the steel plate decreases, the arc voltage drops. Arc pressure height controller is to detect the arc voltage changes, by controlling the torch of the lifting motor to control the distance between the torch and the plate, the arc voltage remains unchanged, the torch height also remains unchanged.
- For some imported plasma and domestic plasma, in its instructions lists the cutting parameter table, users simply refer to the parameter table, according to the selected current, set the corresponding voltage on arc voltage controller, at the specified speed that Can keep the torch height constant. During the actual operation, the user should set the arc voltage according to the actual situation of the torch height. In the normal state of automatic increase, the higher the arc voltage setting, the torch control height also increased, vice versa.
