Problem Solving

Surface Treatment

  • Gear Peening
  • Airblasting Equipment for Hydraulic valve
  • Blast cleaning system for coiled wire, rod and deformed bar
  • MICROBLAST
What are problems of remaining sand in the valve?

Use of sand core is mandatory to create cavities in the casting.
There are various problems by remaining sand in the casting.
Cleaning of sand is a must.

  • Rapid wear of machining tools
  • Wear of hydraulic pump by sand invasion to hydraulic fluid circuit
  • Malfunction of spool movement caused by sand inclusion
  • Fast wear of sliding part of circuit holes
Solutions for problems
  • Case 01Environment improvement
  • Case 02Cost reduction
  • Case 03Reduction of labor and time
  • Case 04Stable quality
  • Elimination of chemical solution
  • Elimination of manual work

Mechanization and automation

Proposal of mechanization and automation

  • Combination of “Air Blast” and “Robot” solves the problem.

  • Robotic Air Blast System “MYR”

Why Air Blast?
Elimination of chemical solution
Safety

No use of chemical solution

Cost reduction

Not necessary of waste water system

No electricity for heating

No use of chemical solution

Outsourcing cost elimination

Easy automation and labor reduction

Environment

Leave off of high temperature environment

Elimination of manual work

  • Case 01Automation reduces labor and manual work.

  • Case 02Accurate spot processing by programming.

Why robotic system? – Pinpoint treatment

  • Target spots can be accurately blasted by robot.
    By using interior nozzle, deep spots can be blasted.

  • Contributing quality improvement
