BAYO T-REAM a new Interchangeable Reaming Head System
Introduction
ISCAR is introducing the BAYO T-REAM, a new high speed reaming system. The BAYO T-REAM consists of an interchangeable carbide reaming head with a unique (patent pending) quick-change bayonet mechanism, suitable for reaming applications of 9.5 up to 32 mm H7 hole tolerance range.
The reaming head is mounted on a HARD TOUCH steel shank (solid carbide or heavy metal shanks are available on request). A bayonet screw attaches the reaming head to the shank and a special key is used to clamp and release it.
The reamer has been designed with internal coolant holes for the most efficient head lubrication and extremely long tool life.
Application Range
The BAYO T-REAM reamers were designed for high speed reaming. In comparison to the conventional method, this advanced solution allows increasing the feeds dramatically (by more than 30 times). This feature is most advantageous in mass production industries. When large quantities of workpieces are involved, the savings in machining time, labor cost and productivity are multiplied greatly.
The BAYO T-REAM reamer is more expensive when compared to a conventional reamer. However, due to its high productivity, shorter production time and elimination of setup time, the tool cost per part is significantly lower.
The BAYO T-REAM reamers can be used for blind and through holes as well as for holes with cross holes or keyways. Moreover, they can be used for a very wide range of workpiece materials.
Advantages
• High speed/high production.
• No setup time.
• Low runout (maximum 3µm).
• One shank can be used for a range of hole diameters and various types of cutting edges.
• Durable, due to the combination of a carbide head and steel shank.
• No fear of losing any clamping parts which may fall during indexing.
• Internal coolant directed optimally to the cutting edges.
• Possibility of applying minimal lubrication systems.
• No need to remove the tool, due to the frontal indexing system.
Guidelines for High Speed Reaming
As the cutting speed and feed are much higher than in conventional reaming, the following guidelines should be adhered to:
• The machine being used should be in good condition, meaning:
- very rigid, to minimize vibration and low runout
- equipped with an internal coolant spindle
• The reamers being used for high speed reaming are usually coated or made from PCD/CBN. Users who regrind their reamers should recoat them for further high speed operation.
• Conventional reaming should be considered:
- when the machine is not sufficiently rigid.
- if only external cooling can be used.
- in special applications such as thin walled tubes or when reaming soft materials (plastic, etc).
- when there is a demand to use floating adapters (GFI).
