ISCAR TECH TALK - ISCAR SUMOCHAM for Drilling Operations
The ISCAR SUMOCHAM line for drilling operations.
The SUMOCHAM line has a new unique pocket design that uses resulting cutting forces to tighten the exchangeable drilling head, which provides extremely rigid mounting. The greater the effect of the cutting forces, the greater the clamping force of the head.
The SUMOCHAM line is user-friendly and assures quick and easy replacement of exchangeable drilling heads with emphasis on ISCAR's no set-up time phenomenon.
The tools are embedded with the revolutionary technology of twisted coolant channels. This modified twisted coolant channel design features increased flute volume that greatly contributes to effective chip evacuation.
ISCAR's SUMOCHAM exchangeable drilling heads are available in a diameter range from 4 mm up to 32.9 mm and include 10 standard geometries that are suitable for the most popular and common material groups used daily in diverse industries. The inserts are supplied with a user-friendly key that enables easy mounting with no set-up time.
The ICP geometry is designed for ISO P materials and is ideally shaped for high productivity and excellent chip control for machining alloy steel.
The HCP geometry, with a concave cutting edge, is used for self-centering the drill and ensures drilling operations with a depth of up to 12xD without the need for a pre-hole.
The FCP geometry provides a practical flat bottom hole often required in various operations.
The ICK geometry is designed to machine ISO K materials at very high feed rates.
The ICM geometry maximizes productivity when machining austenitic stainless steel and other ISO M materials.
The ICG geometry has grooves on the cutting edge designed to break the chips into small segments which can be easily removed from the cutting area.
The ICN geometry has sharp edges and polished chip flutes for ISO N type materials.
The QCP geometry with a double margin is used for drilling with high surface quality and improved self-centering capabilities.
These wide range of tools ensure drilling with depths from 1.5xD and up to 12xD. For deep drilling it is recommended to use the SUMOCHAM exchangeable drilling heads with SUMOGUN tools that provide drilling holes with a depth of up to 40xD.
SUMOCHAM tools are available with 2 standard shank types.
• A round shank that is suitable for hydraulic and collet chucks, and reduces the runout of the cutting edge, which is very important for drill lengths over 5xD.
• A side lock , cylindrical shank with one or two parallel flats for side clamping systems. Side lock shanks provide a safe and rigid drill that is clamped in a toolholder to prevent the tool from being pulled out. This method provides a high level of torque transmission and is suitable for heavy machining operations.
The SUMOCHAM line also includes tools for combined drilling operations such as drilling and chamfering which implies that one tool can be used for two operations for greater productivity.
I would like to remind you to download the ISCAR World app which features the revolutionary NEO-ITA for achieving optimal machining results.
