Main Features 1. O-type closed press frame special for servo punch press, holistic welding structure, stress relief from tempering treatment. The strong rigidity and high tonnage ensure the stable accuracy for long time, extend the service life of the machine and tools, and improve the positioning precision, reliability and durability of the punch press. Â 2. The worktable surface with hard brush and steel ball, to lower down the noise while working and protect the surface of the sheet. Â 3. The big space between guider will benefit with processing accuracy while fabricate large size sheet, and it has the better balance capacity while moving in high speed. Â 4. The auxiliary platform can move with the sheet, reduce 30% of the friction force between the plate and brush platform. Â 5. The floatable clamps reduce the deformation of the plate. With long clamps carriage, strong rigidity, clamps can move easily, The self-protection function makes no dead area for punching on sheet. Â 6. Line guider and ball screw import from Taiwan HIWIN or German Rexroth, ensure the accuracy and long service life. Â 7. The imported Pneumatic, and electric parts ensure the overall performance reliability. Â 8. Centralized lubricating system, reduce the friction of all moving parts, prolong the service life of the machine. Â 9. With knock-down hole, stretching, blinding, trimming and cutting angle, lettering type function. Â 10. International standard long guide tool, different specifications with reasonable stations distribution, save tool cost and decrease the operation cost.

Quality CNC Hole Punch for metal
Calcium carbide is an inorganic substance, the chemical formula is CaC2, the main component of calcium carbide, white crystals, industrial products are gray-black lumps, and the cross section is purple or gray. It reacts violently when encountering water, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding, etc.
Acetylene produced by the reaction of calcium carbide with water can synthesize many organic compounds such as synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc.; at the same time, acetylene-oxygen flame is widely used in metal welding and cutting.
Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. The relative humidity is kept below 75%. The packaging must be sealed and protected from moisture. It should be stored separately from acids and alcohols, and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage.
