High Quality Super Polishing (HQSP) - ELECTRICAL DISCHARGE MACHINE

An Innovative Technology for Machining Breakthrough in G7-3C Molds

This all new electrical discharge machine with extra fine powder added into working fluid provides a revolutionary machining method for cutting-edge production. The MOLDMASTER new HQSP series is especially ideal for large mold machining which requires uniform luster-effect on the machined surfaces. The HQSP series not only increases the fine machining speed, but also saves time and efforts in manual polishing. It also greatly upgrades mold accuracy and quality.

WORKING PRINCIPLE

For over years, the conventional mirror polishing has been only applied for working area under 30mm diameter and with the use of mirror polishing circuit. It cannot work for a large area to create a lustrous mirror-polishing surface. The restriction for such machining method is poor dust removing due to too close gap, which results in discharge concentration. But now with the addition of powder, gap can be increased to disperse discharge for increasing efficiency. In addition, a large area also can be fine finish machined uniformly to your desired luster-effect.

CHARACTER DESCRIPTION

★ Increase Luster-Effect Surface Area
The maximum working surface area for a conventional mirror polishing machining is only of up to φ30 mm diameter approximately. However the maximum working area for the HQSP reaches 400 cm2，and creates a Rmax=1~3μm surface roughness.
★ Apply Graphite Electrode for Luster Machining
A graphite electrode applied for fine finish machining usually causes too much wear, and is difficult to achieve uniform and fine surfaces of mold. The HQSP features outstanding dispersion performance, permitting luster-effect machining accomplished easily.
★ Increase Fine Machining Speed
The time required for luster-effect machining on the HQSP is only 1/2-1/5 of that on a conventional machine.
★ Minimum Surface Cracking
Cracking depth on a surface machined by HQSP is greatly reduced when inspected by a microscope, which also provides an increased rusting-proof capability. The hardened structure under the surface with a luster-effect machining is uniform, which saves time and efforts in manual polishing operations.
