Spindle Unit
The SIGA Spindle Unit has been on sale since 1960 and has been adopted in major production sites both domestically and overseas for many years.
Our rich lineup established by that know-how is highly valued for its durability and short delivery time, and we still have many customers who specify "The spindle is SIGA" when creating new dedicated machine tools.
If the unit you request is not in the lineup, we also support the production of special items from one unit.
We also support bearing replacement and overhauls, so you can use it for a long time.

Pressure and Temperature Compensated Single-stage Shut-off Valve
Model HF-TGM
This shut-off valve is used to adjust the feed motion and speed of machine tools and other equipment. By the movement of the cam plunger, it changes the circuit to switch between rapid feed, cutting feed, and rapid return, and adjusts the cutting feed using the built-in flow control valve. It is equipped with pressure and temperature compensation, ensuring a constant controlled flow rate regardless of pressure fluctuations and viscosity changes due to temperature variations at the inlet and outlet.

Pressure Compensated Two-stage Shut-off Valve
Model HF-ZGMD
The two-stage shut-off valve is used to adjust the feed motion and speed of machine tools and other equipment in two stages. By the movement of the cam plunger, it changes the circuit to switch between rapid feed, cutting feed, micro feed, and rapid return, and adjusts the cutting feed and micro feed using the built-in flow control valve. It is equipped with pressure compensation, ensuring a constant controlled flow rate regardless of pressure fluctuations at the inlet and outlet.
