H Frame Double Crank Split Type Precision Press (YDH)

When buying an H Frame Double Crank Split Type Precision Press, there are several key features and specifications to consider:

1. Frame Structure: The press should have a rigid and even layout frame structure, which can efficiently eliminate deformation. The ALT series H type press machine is a closed type double-point circulating thin oil lubrication.
2. Guide Rails: The press should have ultra-long eight-sided guide rails that can maintain good precision under a little eccentric load. The slider guide should adopt a four-corner and eight-faced super long guide rail which has a strong anti-offset ability.
3. Transmission Device: The crankshaft and the slider device should be connected by a double-link transmission device.
4. Control Core: The control core of the press should adopt PLC and be equipped with a touch screen man-machine interface.
5. Safety Features: It should adopt an international famous brand photoelectric protection device to ensure safe working conditions. Each of the four columns should have an emergency stop button.
6. Technical Parameters: Consider the capacity, rated tonnage point, stroke length, speed per minute, die height, slide adjustment, slide area, bolster area, bolster thickness, slide opening, face height, work energy, main motor, slide adjust device, and frame structure.
7. Accessories: Check if it comes with standard accessories like hydraulic over-load protector, inverter, slide adjust device, die height indicator and optional accessories like electrical automatic lubrication system, pneumatic die cushion device, foot switch, quick die change device (Die Lifter, Clamp And Die Arm Shift Mode).

Remember to always consider your specific needs and requirements when purchasing such equipment. It’s also important to buy from a reputable manufacturer or supplier to ensure quality and after-sales service.
