What is a vertical machining center for a precision electronics mold manufacturer?

Release time:

2020-07-16

With the continuous improvement of people's consumption level, higher requirements are put forward for the quality and personalization of products. Electronic product manufacturing industry mold manufacturers to mold as a work of art to process, the processing accuracy and surface quality of the extremely demanding requirements, but also requires a very short delivery time.

As we all know, vertical machining center is one of the most important equipment in precision mold manufacturing. As the benchmark of the industry, Makino Machine Tool has successfully introduced F series, V series and iQ series vertical machines to the market. With the higher requirements of the electronics industry for processing accuracy and efficiency, the Muye R & D team once again broke through the limit and built a new generation of vertical machining center e500.

Makino New Generation Vertical Machining Center e500

Makino e500 series has the characteristics of high rigidity and high efficiency of V33i series, and its processing accuracy can be comparable to that of iQ series with ultra-high precision. Thus, the comprehensive performance of the vertical machining center will lead to a new level.

It is named after the English letter e, because this machine tool is specially developed for the electronic product manufacturing industry (EMS), and it also has multiple meanings:

high reliability.

High rigidity mature structure, 3 axis linear motor

efficiency high efficiency

30000RPM electric spindle, can realize Φ8mm tool opening

extra-high accuracy ultra-high precision

Program resolution 0.00001mm (5 decimal places)

Grating resolution 0.00000125mm(1.25nm)

eco energy saving and environmental protection

Water-cooled freezer, the heat discharged from the equipment is not in the workshop

Easy to use

Pro6 control, simple and easy to use, the dependence on people to reduce to a very low

1. e500 machine features

1) High rigidity and high reliability

The weight of the bed of 8400kg and the unique structure can make the movable part lightweight. The independent structure of XY axis ensures the high rigidity of the feed shaft. It is equipped with the feed shaft independently developed by Makino and SGI. 5 control function, under the premise of constant quality, the processing efficiency is increased by 30% (the premise of high speed is to ensure accuracy).

2) Ultra high precision characteristics

Roundness <1μm, and does not change with load-bearing and feed changes; The resolution of the grating ruler reaches 1.25 nanometers, and the program resolution can reach 5 digits (0.00001mm) after the decimal point, which fundamentally has the characteristics of high-precision micromachining.

Roundness <1μm

Comparison of arc trajectories at different resolutions

3) Linear drive

Compared with ball screw drive, linear motor drive does not have screw backlash when the motor reverses, but heat generation and end effect are the difficulties of linear motor. Makino adopts spindle center cooling technology, and the linear motor stator and mover are cooled separately, effectively overcoming the technical problems. Compared with ordinary linear drive, the direct drive of Makino will not increase the pressure of worktable and guide rail and affect the processing accuracy.
