精密珩磨機型號YHHM400B主要用途 Main purpose:

本機是主軸和工作臺雙變頻的機型，適用于珩磨活塞環外徑，錐面環的接觸亮帶和桶面環及外圓拉毛、滾花形狀等特種環的加工。

It’s a double-conversion model with spindle and working table. Suitable for honing the outer diameter of piston ring , the contact bright band of taper face ring ,barrel surface ring and the special rings like cylindrical nap , knurled shape.

精密珩磨機YHHM400B技術特點 Technical characters:

1.采用優質鑄件，滑枕選用高強度球黑鑄件。

2.采用曲柄連桿機構帶動裝有珩磨軸的滑塊完成機械往復運動。

3.主電機與珩磨套旋轉電機采用變頻器無極調速，可使珩磨軸上下珩磨運動與珩磨套旋轉運動處于*匹配狀態。

4.珩磨液采用自動分級變量加液裝置。進料動作由油缸自動控制，磨液供.停由電器自動控制，可提供粗，半精，光磨三級磨料控制，且供給量可調。

5.采用PLC控制。

1. It adopts high quality castings  For the ram, uses the high-strength black ball castings.

2. With the mechanism of crank connecting rod to make reciprocating movement and realize honing.

3. The main motor and rotating motor of honing sleeve use Inverter for stepless speed control , which can make honing axis up and down movement and rotary motion of honing sleeve in the best matching state.

4. Honing liquid adopts the automatic classification variable dosing device . The feed action is automatic controlled by cylinder. And the grinding fluid feed and stop is automatic controled by electrical, which can provide a rough , semi- refined, and buffing grinding. The supply is adjustable.

5.Adopts PLC control
