Machining Method
• Basic Machining Method
First operation: Use the basic hole tool to machine 1 to 2 journals on the near side to serve as guide holes.Second operation: Use the long tool to machine the journal on the far side using journals 1 to 2 (near side) as a guide.
* Finish the journal just machined with a single tooth using the pad as a guide.
• Other Machining Methods
(1) Flip the work over and machine using the basic hole tool working from left to right.
(2) Install a guide bush (reference hole) on the near side of the work piece and machine using only the long tool.
• ApplicationAutomotive manufacturer: tools for crank shafts and camshaftsConstruction machine manufacturer: drilling tools for hydraulic
pipe joint parts
• Characteristics- Tool body and cutting edge (consisting of blade and pad) replaces line boring bars.
- Usable on machining centers for lower machine costs.- Features clamp-on carbide pad for easy maintenance.- Achieves high precision machining.- According to the work material, carbide/SUMIBORON/SUMIDIA cutting edge grades can be selected
- Supports both inserts and blade cutting edges.

Recommended Cutting Conditions (SUMIBORON) vc = 800 to 2,000m/min fz = 0.05 to 0.20mm/t ap = 0.3 to 3.0mmDry
• Adopts the high-strength SUMIBORON BNS800 grade, to support high-speed/high-efficiency cutting.• Uses a two-sided 8 corner insert, achieving lower costs.
Insert can be reground and is therefore economical.• Simple insert mounting design for easy yet precise tool adjustment.
Characteristics
Inserts can only be reground once (inscribed circle dimension must be at least 9.125mm)When using a reground insert, make sure all inserts are also reground.Do not mix new and reground inserts on a single cutter setting.

Typical Power Ratings
<CAUTIONS> Power ratings are subject to change based on conditions such as work material and cutting speed and should only be used for reference. Cutting Conditions (Reference)Work material : S50C (230HB)Cutting speed : vc=150m/min
<CAUTIONS> Coolant volume is a factor that affects drilling performance, particularly with respect to chip evacuation and lubricity. Coolant pressure should be set higher for smaller diameter drills. (ø18.0 mm or smaller) Coolant volume is usually adjusted by changing the coolant pressure provided on most CNC machines. This table provides guideline values only. More coolant may be required depending on the machine, coolant, and work material.

(1) Drill a guide hole using the dedicated PHT series • Select the same nominal diameter for the guide hole drill PHT series as the deep hole drill XHGS series.
(The guide drill diameter is designed +0.02 mm to +0.05 mm larger than the long drill diameter)
(2) Feed the deep hole drill XHGS series through the guide hole at low rotation speed • Rotation Speed : 500min-1 • Feed Rate : 1,000 to 2,000mm/min
(3) Increase rotation speed until the set cutting speed is reached, and start normal drilling operation
(4) After drilling, rotation speed is reduced and the drill is retracted from the work material • Rotation Speed : 500min-1 Feed Rate : 1,000 to 2,000mm/min
150˚
H H = Drill diameter x 1.5 to 2.0 times depth
1Stop 1mm away from the guide hole depth
Increase rotation speed
Change the rotation speed to 500min-1.
Recommended Drilling Method
* If the drill is inserted into the guide hole at the set cutting speed, peripheral run-out may cause damage to the drill's peripheral edges.
* On some NC machines, the feed command may be activated before the set spindle speed is reached; so it is recommended to enter a dwell sequence before the feed command.
* Retracting a drill from the work material at a high rotation speed is dangerous as doing so may result in breakage due to run-out.
(5) Other Notes • A flat base should be prepared when the surface for the guide tool is slanted.
• If the exit side is a non-flat surface, reduce the feed rate to f=0.05 mm/rev immediately before the breakthrough point to prevent the drill from breaking or burrs from forming.
(1) Internal coolant supply • Use JIS A1 class 1 oil or equivalent (emulsion). • Pump pressure Steel: 1.5 to 2.0MPa (Cooling effect increases at higher pressures, which affects chips and wear)
Cast iron & aluminium alloy: 4.0 to 6.0MPa (Priority on cooling)(2) Internal MQL
• Air Pressure : 0.5MPa or higher • Discharge volume : It is recommended to set the maximum discharge volume possible on the machine. * Consult the manufacturer if you intend to machine aluminium alloy.
(3) Internal dual-liquid mist • Air Pressure : 0.5MPa or higher • Discharge volume : It is recommended to use the optimum settings for your machine.

- High rigidity (almost 3x) compared to cross-key type helps extend tool life!
- Designed to tolerate thermal growth and displacement for good milling precision.
- Highly durable clamp and long body life.
- Unique tapered spline system drastically reduces cutter replacement time by

- Improved cutting performance and insert life - Reduced cutting noise - Improved efficiency - Processing precision improved with suppression
of heat generation in work materials
Inserts with Chipbreaker Designs
• Reduced relief angle on outer insert from 4°10' to 0°30' improves surface roughness in thrust direction.
Molded chipbreaker achieves low cutting resistance.* For applicable sizes,
please contact us directly.
Designed for High-precision Machining
Improved Accuracy of the Cutter Body- Use of spacers at insert mounting positions allow precise
control over diameter and width.

• Prevents mis-clamping of inserts
In conventional types, there is a possibility of insert
mounting error because the external appearance of
the insert seat is 90°, but the negative-positive type
eliminates such errors as the seat angle looks very
different.
- High precision machining - Improved body life (durability) - Improved insert life

Process Combinations with a Turn Broach
Please contact us to select the optimal grade based on your work material.
Both CVD and PVD coatings can be applied.
- Allows conventional turn broaches to be used for turning.- Tool can be used for turning, plunging, and broaching.- Similar to mounting the tool post of a turret lathe onto both
heads of a machine spindle.
- 30 to 45 cartridges equivalent to turning tool holders can be mounted on the body. (Diameter = ø525 to ø700mm)
- Machining processes are relatively easy to change making this combination suitable for a variety of machining applications. The combination offers ability to index each cartridge at high speeds, broach, and use various cutting edges.
- High speed indexing reduces idle time, and optimized cartridge layout enables many hours of automatic operation.
