梅里特波尔压缩机厂制造并在生产中采用了压缩机阀片淬火矫形和回火用的机械化四工位自动机床。 机床（见图）的结构紧凑、简单,维护使用方便。用不锈钢制成的推进刀（3）把最下层的阀片（7）（位置1）从加料斗 （8）中推出,使之落至石棉水泥工作台（4）上,并由升降定位肖（6）使阀片定位。当推进刀停止运动以后,装有阀片的工作台与制动器（9）脱开,而跟旋转着的锥形橡皮轮（10）接触,并开始反时针旋转。 位于工作台上的单圈感应加热器在工作台开始旋转时就立即供热（由高频表面淬火装置TBЧ“ЛПЗ-67”）并把阀片加热到约950℃。
Meritopol Compressor Factory manufactures and uses mechanized four-station automatic machines for the compression of valve disks for hardening, orthopedics and tempering in production. Machine (see photo) compact structure, simple, easy to maintain. (3) Push the lowermost flap (7) (pos. 1) out of the hopper (8) and onto the asbestos workbench (4) and lift it down (6) to position the valve. When the advance knife stops moving, the table with the valve is disengaged from the stopper (9) and comes in contact with the rotating conical rubber wheel (10) and starts rotating counterclockwise. The single lap induction heater located on the work surface is heated immediately after the work surface starts to rotate (TBHC “ЛПЗ-67” by a high frequency surface hardening device) and the valve sheet is heated to about 950 ° C.
