Accuracy of the press machine

(Performance comparison)

■ C-frame power press with problems such as frame deflection

■ Dieing machine (Highly rigid structure)

●　Dieing machine ( high value-added production, high-speed, high efficiency press machine)

■　This dieing machine has four (4) sturdy posts (rods) supporting a rigid upper plate and lower plate.

■　The structure of the press mechanism of this dieing machine is strong against eccentric loads for high-speed precision press operations, and thus is perfect for cost-cutting.

■　With the motor located at the bottom of the machine and with a low machine height, this precision press machine is capable of achieving high-efficiency production.

■　This reasonably-priced machine is a 4 rod, down-pull stroking type dieing machine, excellent in preventing problems in die galling.

■　Because the bolster on the dieing machine is open on all four sides, processing materials can be led into the machine from multiple directions and integrated into one process, leading to higher productivity.

■　With a high machine perpendicularity, this dieing machine is capable of consistently achieving accuracy levels at the highest JIS grade levels

●　Dynamic accuracy of C-frame power press machines with problems in frame deflection

■　In power press machines, the frame of the machine will stretch upwards or downwards when the material is pressed, affecting the accuracy of the pressing die.

■　In power press machines, the “punch-through (breakthrough)” motion, which occurs during the pressing process, greatly wears out the die.

■　In power press machines, frame deflection (angle: α°) occurs and causes abrasion in the pressing die and affects processing accuracy

■ Known problems in processing accuracy of C-frame power press machines

　

●　Types of press-machines (Terminology)：
■　Dieing machine: A machine with excellent frame strength, lower dead-point accuracy and speed, efficiency, and suitable for achieving high value-added production.

■　Servo press: A multifunction press machine. The motive power is transmitted from the flywheel to the servo motor.

■　Dieing machine-type servo press machine: A machine with a sophisticated structure suitable for processing materials which are difficult to process.

■　High-speed automatic press machine: General term for standard high-speed pressing machines with CNC (Numeric-controlled) automatic feeding machines.

■　C-frame clamp press machines: General term for standard C-frame power press machines.

■　Straight side press machine: More common in larger machines, straight side presses consist of frames on all four sides to reinforce the body of the machine.

■　Transfer press machine: Pressing machines which process multiple rows of semi-manufactured materials, on the bolster,
