Skillfully change to the top

When roughing and forging the blank rod parts on the lathe, it is necessary to use the live top support. Due to the irregular shape of the blank and easy positioning during the clamping, the top is strongly stressed, and the top head is often broken or burned. The entire top is also scrapped. To this end, we have improved the original top-grade foundation soil and achieved good results. The improvement method is as follows: As shown in the figure, the top of the original waste top (as long as the bearing is not bad) can be extracted and used as a top. The sleeve is set in the bearing, and the top tip is only used. When the tip is damaged, it is only necessary to replace a tip. Thus, the entire tip body and the bearing can be scrapped.

Sds Drill Bits

SDS Plus and SDS Max drill bits can be used for drilling operations in concrete, reinforced concrete, granite and similar materials. SDS-Plus has a drilling diameter of 4mm to 32mm and a drilling depth of 110mm to 1000mm; SDS-Max has a drilling diameter of 12mm to 52mm and a drilling depth of up to 1200mm.

SDS Drill Bits are available with two (properly shaped integral straight edges), three (star arrangement) or four (integral cross arrangement) inserts, made of cemented carbide. They are deeply embedded in the steel head with industrial solder and are characterized by a high degree of mechanical and heat resistance.

SDS Plus and SDS Max Bits should not only be selected based on the diameter of the drilled hole, but also their depth standard. Both of these measures are necessary to maximize productivity.
