The data that comes with the machine
·Provide one set of technical information.
·Provide one set of operation manual.
·Provide one set of safe operating procedures.
Machine acceptance requirements
The machine fundation should meet the basic installation requirements.
No large impact sources around the machine .
There should be no welding defects such as cracks, blowholes, slag inclusions at all welds of the machine.
All moving parts of the machine must not be loose or stuck
All terminals and components in the electrical box must not be loose
Check whether all safety protection devices work sensitively and reliably.
Check all gas supply lines for leaks (soap liquid inspection method)
The machine must be well grounded.
Machine tool installation of customer site requirements (prepared by customer before equipment arrives)
NO. | Contents |
1 | Control system power supply capacity: not less than 4.5 KVA. |
2 | Power requirements: （1）3×380v±10%/50Hz，220v±10%/50Hz （2）Three-phase voltage stability is less than ±5% Three-phase power unbalance is less than 2.5% (3) Can not meet the above power requirements, it is recommended to use a regulated power supply Note: The power supply voltage is not allowed to have sudden jumps and sudden power failure, otherwise it is easy to cause damage to the equipment and CNC system and plasma power sourse; there must be a good ground (ground resistance less than 10 ohms) |
3 | Plasma power source working gas and auxiliary gas for cutting: Working gas: air oxygen |
4 | Cutting pipe: smooth, evenly rolled, ellipse deviation ≤1%, reaching ISO standard |
5 | Air Compress Station Requirements （1）Air supply capacity: 0.9 m3/min （2）Air supply pressure: 8.3 kg/cm2 （3）Dew point temperature is not higher than 5 ℃: oil content ≤0.003ppm solid particles ≤0.01 microns （4）Use oil-free air compressors, freeze dryers and precision filters (the system cannot have rusty components), and add an air storage tank to avoid unstable gas supply. |
6 | CNC cutting machine installed place and the environment requirements. （1）Temperature requirement: -10-50℃ （2）Humidity requirements: <90% non-condensing （3）The site should fully meet the needs of equipment placement. It is recommended to isolate the plasma power source to avoid interference from the plasma power source to the system. |
7 | Flame cutting gas requirements Gas type: propane\acetylene\propene\natural gas. Gas pressure 0.05-0.1 MPa Cutting oxygen pressure 0.5-0.8 MPa Preheated oxygen pressure 0.4－0.6MPa |
8 | Equipment operators should have high school or technical secondary school education level, should have experience in operating computers and general CNC machine tools |
9 | The user needs to equip the equipment with a programming computer. Install AUTOCAD2010 version and Excel software before the equipment enters the factory, and install in advance according to the computer operating system 32-bit or 64-bit. |
10 | Before the equipment is installed in customer’s factory, according to the content of "Power and Gas Requirements" provided by Yomi, and prepare for the installation conditions in advance. After confirmation, we will arrange after-sales technicians to visit. |
Demand side obligations
1.The buyer is responsible for laying the gas source and power source that meet the requirements of the site, and the user is responsible for the construction of the brackets for hanging cables and pipelines
2.During the installation and commissioning process, the buyer must actively cooperate to provide the necessary equipment and personnel support (such as lifting equipment, electric welders and fitters, etc.)
3.Requirements for operation and maintenance personnel: 1 operator, secondary technical school or above, proficient in computer operation, proficient in AutoCAD and other drawing software; maintenance personnel: 1 mechanical, 1 electrical, high school or above, or many years of professionalism repair experience.
After-sales service
1.The warranty provides shall be twelve(12) months from the date of satisfactory installation of equipment for components/workmanship. During one year warranty period, the supplier shall be provide free repair service in case of failure due to defective part/ component and replace defective part/component free of cost.
2.During the 1year warranty period, the Supplier shall be provide free repair service for failure not caused by personal factors (the local transport, Visa, air ticket, food, accommodation, translation, internet, communication and travel allowance etc for foreign users should be borne by the User. Such expenses are not included in the quotation) and free replacement for various parts damaged not due to personal factors (sent to foreign users by mail or express, express and the expense borne by buyers). For the repair for failure occurred not within the warranty period, certain charges will be collected.
3.The NC system possesses the standard functions that meet the basic functions of the control system and optional functions needed for future expanded welding. The mechanical part adopts combined, replaceable and standardized structure. Through upgrading of software and hardware, and repair and replacement of mechanical unit, the equipment can maintain long term precision and normal work.
4.Software upgrades and process improvements shall be provided free of cost by supplier to buyer periodically
