For limited sales areas
Connection mechanism is based on a simple
design but assures strong face contact.
Accurate repeatability of 2μm or less
Free to assemble for required
cutting depth and diameter
Efficiency of boring operations are
now further improved by the addition
of new series of boring heads.
Diameter : ø20 - ø203
TWBORING HEADPAT.
Priority is given to rigidity.
Triple contact for highest rigidity
Cartridge and head are clamped together with face contact, increasing the rigidity for heavy duty boring.
Diameter : ø25 - ø150
RWBORING HEAD
Priority is given for unique and multi-functional uses.
Rigid balanced cutting is available
RW Head is designed for adjustment to both radial and axial directions.
Cartridges are standard for through-hole and blind-hole boring, thus universal for various requirements.
Diameter : ø20 - ø203
EWNBORING HEADPAT.
More versatile in function and performance
by a new design concept.
Back boring is available to optimise opposing bore concentricity
Back boring from the same direction greatly improves the concentricity.
Simply reversing a standard Insert Holder readies the tool for back boring, retaining all the same features such as simple and accurate diameter adjustment.
Quick adjustment
within micron tolerance
Completes boring operation
and undercut
No radius at the bottom corner. Ideal finish for bearing seats and cylinder for piston. Easy attachment with standard EWN Boring Head.
Diameter : ø32 - ø70
EWB-UPBORING HEADPAT.P
1 division = 0.001mm/ø without vernier
High precision & easy to adjust for 1µm
in diameter
After test cut, precisely adjust to the finish diameter by using the Fine Adjust Dial. High accuracy scale of 1 division = 1µm/ø assures easy and fast adjustment
Imbalance compensation feature assures high speed operation
Balanceable to G6.3 at the max. spindle speed. By adjusting the balancing dial to the required boring diameter, built-in counterweight compensates imbalance and high balance quality is obtained.
Diameter : ø100 - ø203
EWB ALUMINUMBORING HEADPAT.
Light weight & automatic precision balancing
Capable for use on small machines with weight restrictions
Automatic imbalance compensation design
Diameter : ø32 - ø105
EWBBORING HEADPAT.
Bore diameter adjustment simultaneously compensates imbalance. Thus, stabilized boring at high speed is possible.
Automatic imbalance compensation design
Diameter : ø1 - ø50
EWNBORING HEAD (Cylindrical Toolholder Type)
3 sizes are available in the series
to do the best job from selection.
Combination with carbide cylindrical toolholder for reliable deep hole boring
Carbide is three times more rigid than steel against bending. Thus using a carbide shank tool provides more accurate and stable boring.
• Steel shank
• Carbide shank
Diameter : ø1 - ø50
EWBBORING HEAD (Cylindrical Toolholder Type)
Fine adjustment for diameter
by 5 micron/diameter per each division (EWB2-50CK6)
Manually balanceable design
Rotating Balance Ring moves counterweight inside for balance adjustment.
Diameter : ø1 - ø15
EWN04-7CK1 / EWN04-15CK3(Cylindrical toolholder type)
Body diameter ø18.5mm (EWN04-7CK1)
Micro boring head
- High precision diameter adjustment is achieved despite its ultra small size. Fine adjust dial assures easy & fast adjustment.
- 1div.= 0.01mm/ø + 2µm Vernier
Diameter : ø150 - ø830
BORING HEAD for large diameter
Utmost benefit of modular system;
Extended boring capacity up to 830mm with standard items.
- Finish boring head offers high precision adjustment of
1 div. = 0.01mm/φ and back boring capability.
Diameter : ø200 - ø410
HIGH SPEED BORING HEAD for large diameter
Introduction of high speed to large
diameter boring!
- Light and rigid with reinforced aluminum components.
- Positioning pins securely hold the head.
