What are the classification of woodworking engraving machine gantry?

Woodworking engraving machine planer according to the material, usually have a cast iron gantry and cast aluminum gantry. 1, cast iron cast iron of longmen longmen weight is large, and the price is high, so low in popularity in the market, not accepted by most of the manufacturers. 2, cast aluminum longmen cast aluminum gantry light quality, strength, is now leading products. Is directly proportional to the pressure and friction force, so the quality of the lighter, the less friction. The damage to the movement to the device is smaller, the smaller the electrical resistance of the stepper motor. Speed is faster. Cast aluminum gantry light quality, strength, is now the dominant product 3, with the development of the gantry material control CNC electric unit ( Stepping servo) / Technology updates and carving material hardness, larger torque and more stable, the improvement of the performance of the gantry also by casting aluminum structure to the development of steel structure, steel structure than cast aluminum has better strength and creep resistance, CNC woodworking engraving machine adopts thick wall constructed of square steel gantry structure, provide CNC woodworking engraving machine with a hardened stable processing platform.
