|
|
| |
|
|
| |
Spindle axis |
|
|
| |
The high precision of level of micron is required on dimensional tolerance and geometrical tolerance also at the spindle axis, which is important as central part of machine tools. YSK has the grinding factory at constant temperature and then we can meet those requirements. |

Drive shaft |
|
|
| |
The drive shaft, which is the main axis for transmitting the power to each working parts, needs hardening on required part qualitatively. YSK has induction hardening equipment and then we can control the consistent quality at machining precision and hardening precision also. |

Machining shaft |
|
|
| |
Machining external diameter of shaft is the base machining technology.
YSK can put concentricity at also thin and long shaft with step out. |

Roller axis |
|
|
| |
About the quality of roller axis, which is core part of conveyer, high level is required such as the precision of run out is of course and precision of surface roughness also.
YSK can produce by the facilities of mirror polishing. |

Eccentric axis, Cam shaft |
|
|
| |
A camshaft changing a moving direction, the eccentric axis needs the processing of multi axial directions.
YSK can make various variations by the technique cultivated for many years.

The shaft with quenching processing |
|
|
| |
For a quenched product, it is the most difficult skill to make such as the long keyway or tap.
YSK has completed the technique as a specialized maker of the quenching shafts. |

Gear, Rack machining |
|
|
| |
A gear and the rack, used mainly for transmission of the power, are the indispensable processing for position forwarding and the timing mechanism of the machine tool.
YSK makes from one piece for the customer’s request. |

Machining trapezoidal screw, nut |
|
|
| |
We provide not only rolling trapezoidal screw but machining trapezoidal screw which more highly precise and more difficulty is required.
Also we make the products which include special manufacturing such as BTA machining. |
