Experts pointed out that we must increase the research and development of CNC machine tools in China to accelerate the development of popular CNC machine tools. Manufacturing service competition China's milling machine and machining center market status and prospects Domestic and foreign lathe technology level and development direction World processing center production, demand and development trends Domestic and international machine tool development trends World CNC system development trend Cutting technology and CNC machine tools development of.

Bearing packaging is divided into inner and outer packaging.

After the bearing is manufactured and qualified, it will be cleaned and rust-proofed, and then placed in the inner packaging to achieve waterproof, moisture-proof, dust-proof, shock-proof, maintenance bearing quality and precision, and convenient use and sales. .

The inner packaging of the bearing is divided into three categories according to the anti-rust period:

1 Short anti-rust period packaging: anti-rust period of 3 to 6 months, suitable for large-volume delivery to the same subscriber, the bearings will be put into use in a short period of time. According to the agreement between the two parties, the principle of convenient use is adopted, and simple packaging is adopted. 2 general anti-rust period packaging: anti-rust period of one year, suitable for general purpose bearings. 3 long anti-rust period packaging: anti-rust period of two years, suitable for special and precision bearings.

The inner packaging materials of the bearing are polyethylene plastic tube (box), kraft paper, plain and crepe polyethylene composite paper, carton, polyethylene or polyethylene plastic film, nylon fastening tape or plastic fastening tape, waterproof high-strength plastic tape. , linen bags, etc. All of the above materials are required to ensure the corrosion resistance test of the material is qualified.

The principle requirements for the method of bearing inner packaging:

1 Miniature bearing: Every 10~15 sets of bearings are loaded into a plastic cylinder, and every 5~10 plastic cylinders are loaded into a paper box (or bag, roll). 2 medium and small bearings: multiple sets of bearings are coated with polyethylene film, external kraft paper or polyethylene composite paper; multiple sets of bearings are packed into a plastic tube (box); single sets of bearings are packed in polyethylene film bags, folded or Install a carton after sealing the bag opening.

3 large bearings:

After packaging with polyethylene film or polyethylene composite paper, put it into a paper box; use polyethylene film bag, single package to fold the bag mouth, then put it into a paper box; single set into special plastic box; single A three-layer wrapped package: a polyethylene film tape or a composite paper tape for the inner layer, a fastening tape for the middle layer, and a waterproof plastic tape for the outer layer.

4 extra large bearings:

Single set of three-layer wrapped package (same as above); single-five four-layer wrapped package: after wrapping the above three layers, the outermost layer is wrapped with a layer of linen tape.

For separable tapered roller bearings with an outer diameter of ≥150mm, the polyethylene film shall be placed before the inner and outer components before packaging, or the inner and outer components shall be separately packaged separately. For interchangeable cylindrical roller bearings with an outer diameter of ≥150mm, it is easy to be injured due to the package. Generally, it can be separately packaged by internal and external components.

The general materials and requirements for bearing outer packaging are as follows:

1 double corrugated carton, the total weight (gross weight) of each box does not exceed 25kg, and the plastic packaging straps are bundled outside the box; 2 nail box (wooden box), the total weight of each box does not exceed 30kg, and the outer box is bundled with blue steel strip; 3 calcium Plastic corrugated boxes, the total weight of each box does not exceed 25kg, the box loves to be bundled with plastic strapping.

When loading the bearing product with the inner packaging into the box, the plastic bag or plastic film should be padded inside the box; if there is a gap in the box, it should be filled with dry materials such as corrugated cardboard and paper scraps.
