SOLO 202 30/30/60 quenching machine

SOLO 202 30/30/60 quenching machine built in 2001 in Switzerland, is a multifunctional machine used in the process of workpiece quenching. The quenching process improves the mechanical properties of the workpiece by increasing its strength and wear resistance. The machine’s extensive machining capabilities and high performance allow the following types of metal heat treatment to be performed:
– austenitizing (in atmosphere, protective gas or nitrogen)
– carburizing
– carbonitriding
– water quenching
– tempering (without protective gas)
– alkaline spray washing
– annealing

The SOLO quenching machine of multi-module construction is equipped with two quenching furnaces (a bell furnace and a tempering furnace), two tanks (an oil bath and a water tank) and a spray washing machine with a two-section oil separator for load washing. The furnaces, made of top-quality sheet metal and cast iron sections, are distinguished by good tightness, low heat loss and high thermal efficiency. In addition, they are equipped with lightweight insulation and easily replaceable ceramic resistance heating supports, which provide effective overheating protection.

Loads with a maximum height of 600 mm are transported between the individual machining stages by a manipulator made of welded steel plates. The manipulator performs longitudinal movement on guide rails and vertical movement using an electrically controlled hydraulic cylinder and pedal. To ensure that the machine is convenient and easy to operate, all process parameters are programmed in the control system in the form of a computer and a SIEMENS SINUMERIK S7 CNC controller, which allows, for example, the creation of a programme database or process history. The SOLO 202 quenching machine weighs approximately 5570 kg.
