Coil Spring Manufacturing Equipment
Our coil spring manufacturing machines can produce various types of coil springs.
These coil springs are used for automobiles, trains and heavy machines.
We have made the machines for wire diameter up to 100mm.

STEP 5LOAD TESTING
Load Testing Machine
This machine can measure the load of coil springs with its specified height. Then the coil springs will be classified by the results of its load.
Load Testing UnitB663T
Overview
This is an equipment to measure a load of coil spring after painting one by one and to classify the measured results to 5 ranks. Classification is done by load measuring under specified height. No good product is classified to + NG and - NG, and ejected outside machine. Good product is classified to (+, 0, -) and ejected outside machine. Jigs, which are changed in accordance with both ends shape of coil spring, can be automatically changed by jig changer (Option).

Presetting & Load Testing MachineSA42M
Overview
This machine has a function to make a setting and testing of coil spring continuously. Testing results are classified to 5 ranks (+NG,+,0,-,-NG) and indicated at a display. The machine has a construction to increase or decrease a pressure against spring by power source of AC servo motor and through a ball screw. Consequently, high speed and smooth movement and measuring can be done.
