Be wary of imitations and choose HSD, a BIG PLUS certified manufacturer

HSD has recently been included in the list of certified companies entitled to produce BIG-PLUS compatible tool changing systems.

BIG-PLUS Spindle System is a product of BIG DAISHOWA SEIKI CO. LTD, which surpasses all other spindle concepts by offering interchangeability with existing machines and tool holders. BIG-PLUS is indeed a solution that stands out from other tool holder systems thanks to clear competitive advantages. It is the only system in the world capable of guaranteeing simultaneous double taper and face contact between the machine spindle and the tool holder for tapers 7:24. Consequently, the contact between the machine and the tools is extremely solid, ensuring maximum reliability and precision. The system is based on the most currently available standards for JIS-BT, DIN69871 and CAT-V flange tools.

Besides, the BIG-PLUS Spindle System strictly determines the dimensions of a machine spindle face and the flange face of a tool holder. These dimensions are controlled by unique high tolerance gauges and measuring equipment, so double taper and face contact is guaranteed. Therefore, there is full interchangeability between all BIG-PLUS machine spindles and BIG-PLUS tool holders.

Therefore, the system guarantees users a number of advantages, including an improvement in surface finish and dimensional accuracy, extended tool life and a drastic improvement in ATC repeatability. The BIG PLUS also helps to eliminate Z-axial movement at high speeds as well as prevent fretting corrosion and improve processing accuracy and stability of the processed surface.

BIG-PLUS is a registered trademark and HSD owns the license for the production of compatible tool change systems. Consequently, HSD is proud to be an authorized BIG-PLUS tool change systems manufacturer since this demonstrates the high quality level of our products. Actually, the ability to build tool change systems compatible with the BIG-PLUS is a skill that only few companies in the sector have, since such processes require a high level of accuracy and precision.

Therefore, HSD can today be considered as one of the companies authorized to produce tool change systems compatible with the BIG PLUS and thus able to offer its customers a product capable of improving the performance of their machine.

It should be reiterated that HSD is a company authorized to produce this type of systems because today there are many manufacturers claiming to produce a dual contact tooling system, but only a few have an official BIG-PLUS license. Without a license, these manufacturers have neither the master gauges nor the measuring devices or tolerances to define the critical dimension of the distance between the taper gauge line and the tool flange. Currently, 84% of the tested tool holders are out of the official BIG-PLUS tolerance. Only original BIG-PLUS tool holders enable the advantages and strengths of a BIG-PLUS spindle system. As a matter of fact, BIG DAISHOWA carefully controls 100% of its tool holders and therefore ensures that all products fall within the tight tolerance margins foreseen by the system. Hence, only BIG-PLUS branded tool holders, such as those manufactured by HSD, guarantee an optimal performance in a complete and safe way.
