Features of High-speed Reciprocating Grinding Machine

  • Immediate inversion of the table improves grinding ability.
  • The machine has less heat, less cracks, less burns, and less warping.
  • Fixed position inversion and no vibration help grind smoothly.
  • Causes the grinding stone to be much less worn.
  • Includes supplies for poring water, sucking in dust, and paper filtering.

Strongest Points of Our Grinding Machines

  • Unlike general grinding machines, our grinding machines enable small parts to process highly efficiently.
  • Unlike profile grinders to produce super- precise and hard die part, our grinding machines are inexpensive.
  • Our machines are designed to fit in 1 meter square.
  • Our grinding machines are specialized to grind small parts of extremely hard materials or ceramic materials.

Products which are grinded by our High-speed Reciprocating Grinding Machine

The following machines are in high demand by our customers

Precision extremely hard die parts which is used to produce lead frame in the semiconductor package.

Precision extremely hard die parts which cut the unnecessary lead in the semiconductor package.

What is the “lead frame” like?

“Lead frame”, which is a thin metal board used as inner wires in the semiconductor package, plays the role of a bridge between outer wires.

Materials which enable our high-speed reciprocating precision grinding machine to process

Our machines can work with extremely hard, ceramic, aluminum, iron, and resin materials
