• Raw material storage

Our metalworking workshop is where all machinery will be processed. It is specially equipped with a large lathe for the processing of metal parts.

• Raw material cutting
• Precise cutting
• Metalworking workshop
• Large scale equipment in the workshop

Benefits at a glance:
1. After one-step clamping on the machining center is completed, the digital control system automatically controls the lathe to select and change the cutters, change the spindle speed, the feed amount, the motion track on workpieces and other auxiliary functions. The multiple-process processing on the surfaces of the workpieces is conducted in proper order.
2. The multiple cutters selecting and changing function greatly raises the production efficiency.
3. The workpieces are easily clamped and positioned in vertical machining center.
4. The motion track of the cutters is easy to be observed.
5. The debugging program facilitates the inspection and measurement, which makes it easy to detect problems and stop or modify the machine.
6. The easy formation of cooling conditions makes the cutting fluid reach the cutter and processing surface directly.
7. The three coordinate axes coincide with the Cartesian coordinate system. The perspective is intuitive and consistent with the pattern. Thus the cuttings are easily removed and dropped which helps to avoid scratches on the processed surfaces.

• Large vertical machining center
• Forging processing
• Multi-cutter changing mode
• Parts processing

Main benefits:
1. The workpiece is not affected by stress and is difficult to be polluted.
2. Both the moving workpiece and materials inside the glass shell can be processed.
3. The smallest divergence angle of the laser beam is less than 1 milli arc.
4. The shortest spot diameter reaches micron degree.
5. The shortest operation time period reaches nanosecond and picosecond degrees.
6. Simultaneously, the continuous output power of the high-power laser is up to one to ten kilowatts. Therefore, laser fits for both precision processing and large-scale material processing.
7. The laser beam can be easily controlled, so it is easy to combine the laser beam with precision machinery, precision measurement technology and electronic computers. The processing is highly automatic and highly precise.

• Laser processing center
• Steel sheet cutting

Main advantages:
1. The machine has the functions of direct angle programming and angle compensation.
2. The grating ruler does real-time inspection, feedback and compensation. It is controlled by fully closed loop and the positioning accuracy of backstop and slider deadlock is within ± 0.02mm.
3. The machine has multiple-step programming function which enables it to achieve automatic multiple-step operation. During the multiple-step operation, parts are processed in a single run which greatly raise the production efficiency.
4. Users can choose imported hydraulic system with stable performance and compact structure according to their requirements.
5. Ball screw and synchronous belt can be selected to transmit the backstop.

• CNC bending machine
• Plate bending processing

Major features:
1. The CNC lathe works with high precision and stable processing quality. The multi-coordinate linkage of the machine enables it to process parts in complicated shapes. When the CNC lathe is used to process different parts, we only need to change its numerical control program which helps to save the production preparation time.
2. The CNC lathe possesses high rigidity. The machining load of the lathe can be selected to a favorable amount in order to raise the production efficiency (the production efficiency is 3 to 5 times of ordinary machine tool).
3. The machine is highly automated which greatly saves manual labor. The mass production makes it easy to control the quality of the products. The working demand of operation staff is low, but the technical demand of maintenance staff is very high. The machine center is equipped with ten to dozens of different cutters, which can achieve various types of cuttings such as turning, milling, drilling, hinging in a single run.

• CNC lathe

Frame casting process makes the products preparatory for the general assembly line upstairs. The parts are made of high quality stainless steel. They will be initially processed by workers before they are assembled to achieve the combination of every part.

• Frame welding
• Processing of the finished frames

• Electrophoresis workshop
• Electrophoresis accomplished automatically by the equipment

After that, workpieces are automatically conveyed and transferred to the electrophoresis workshop, where we carry out surface treatment. This giant production line completes the electrophoresis and cleaning of more than 3 equipment sets simultaneously. Its production capacity is 30-40 equipment sets per day which fully meets market demand.
