Due to affordable cost and good performance, widely used in producing various plastic injection molds, such as home applications, electronic connectors, powder metallurgy, automotive molds, aeronautics and astronautics,and other industries.

Mechanical Features

Ø X,Y,Z-axis Japanese Sanyo servo motor control.

Ø High accuracy X, Y, Z three axes P3 grade ball screw.

Ø X. Y. Z axis apply ball bearing and non-back-lash bearing，the machine can ensure the precision of processing.

Ø The three-axis with 1 µ optical ruler is adopted, and the three-axis fully closed loop control design  improves the processing accuracy effectively. (Optional)

Ø The structural parts are manufactured from high quality cast iron (FC-30), tempered and stress relieved for deformation-free，high rigidity and reliability performance.

Ø Table surface is hardened and precision ground, ensuring high machining accuracy and long service life.

Ø The machine has a wide machine base to make sure the machine is strong enough for heavy loading, X. and Y axis have V shape and flat guideway with FEFLON wear-resisting sticker, movement of heavy load is smooth and light, with no crawling phenomenon.

Ø Lubrication system uses recovery mode, rail lubrication action at once, and keep the look clean.

Controller characteristics

Ø 15-inch LCD computer display

Ø Adopts the industrial low-power motherboard, CNC modular structure, the system has good scalability, portability and maintainability.

Ø Anti-oil and anti-pollution keyboard, longer service life and more durable.

Ø Operation panel： It can rotate 90 degrees and comes with a remote control. Easy to operate, convenient and fast to handle. Ensure the comfort of operators in the workplace.

Ø High Frequency Power and the Internal Circuit: The modular design is used in the internal wiring, Creative electric pulse machining with high efficiency. High quality, high precision, high efficiency. which can reduce the probability of the failure, and it's easy to maintain.

Ø Built-in graphite processing circuit: It can process large area, sharp shape, deep hole and thin sheet with a maximum processing efficiency of more than 2 times compared with the old model.

Ø Digital servo system drive three-axis, can flexible choose the servo strategy during machining according to the feedback signal, ensure keeping continuously, steady and high efficiency machining.

Ø Superhard alloy processing circuit: (optional) 

Copper→tungsten steel: It can effectively control the electrode consumption and processing efficiency. The electrode consumption can be controlled below 5%, with faster and finer speed. The surface crack of tungsten steel is smaller, and polishing is easier.

CNC System software operation function:

Ø Simultaneous three-axis control

Ø Auto storage function enjoys a capacity of 100*40000 numbers.

Ø 10 fine processing functions. Moulds can be finished completely from rough to semi-finished to finished products.

Ø Five orbit processing patterns. One mould can be set by 5 different orbit processing patterns.

Ø More than 1000 units of document storage capcity are provided. i.e. more than 1000 different moulds or custormers can be numbered.

Ø Auto correction of electrode consumption. During multi-hole processing, electrode consumption shall be preset, and then the computer can automatically correct the depth of each hole to make sure each hole has the same depth.

Ø Auto finding of moulds and central point, to enable a quicker compensation.

Ø When the condition for discharging is unstable, the computer will correct the discharging efficiency and working period automatically. After stabling all conditions, the discharging will continue automatically. Processing condition can be adjusted at all time.

Ø Auto return to zero for base point: should there be any blackout during auto-processing, the computer can find the base point automatically.

Ø Speedy deslagging:Speed up servicing to improve the processing efficiency without distorting electrode.

Ø Orbit and side processing: Four sided, intersecting, circular, hexagonal, lateral

Ø English/Chinese Dialogue Operation, all processing data can be input easily via keyboard.

Ø Operate “DRY RUNNING” before the actual processing to test the programme.

Ø Function of avoiding second discharging and carbon desposition rapid rising or discharging boundary searching rapid rising.

Ø Power control (equal energy) function for homogenizing the machining effect.

And this function could be switched off to accelerating graphite electrode machining.

Ø It could set that after 2~10 times discharging (jumping up control), the electrode will 5 be raised (safe height Z) to the set arbitrary position and the continue machining. This could achieve good slagging off performance for deep hole machining.

Ø ISO-G Code Program.
