Product Details:

Features:

  • This series power press machine features rigid rotating-key clutch, simple structure, easy operation and convenient maintenance, driven by helical gear.
  • J21S-25 open inclinable punching machines are the domestic first batch of punching machine equipped with ball bearings, high resistance and low noise, instead of traditional sliding bearing (copper tile).
  • J21S open-type inclinable punching machine is unique in the industry, copper tile transmission gear.
  • The improved frame offers high strength and durability.
  • All J21S-80T above punching machines: pneumatic double balancing cylinder structure keeps the slider weight and the upper die weight balanced to prevent shaking.
  • These power press machines can prevent gear colliding, minimize noise, eliminate the gap between connecting rod and slider, and reduce impact and wear of loaded parts.
  • These press machines prevent the slider from falling down when accidents occur such as brake failure or connecting-rod breaking down.

Standard Accessories:

  • China-made high performance motor
