Machining equipment constaints

Along with the need for ultra-high speed and high precision operations, small machining centers without reverse function (tap cycles) have emerged.

High precision and high quality of internal threads

The demands for internal threads are becoming increasingly diffi cult, such as "no room in pilot holes", "high quality with no burrs", and "high precision internal threads".

WH-VM-PNC OSG'S answer to couter these various problems is WH-VM-PNC.

The 3-crest thread lenght reduces cutting

forces and applies a low load to the tool

and equipment

A short overall lenght of 40mm for superb

ease of use.

It uses WXS Coating, with a proven track

record on end mills for high hardened

materials, and an exclusive carbide base

material.

Machining method (Heat resistant alloys/High hardness materials

Recommended Cutting Conditions

Machine three

pitches at the

bottom of the hole

Repeat arc cutting

movement only 1P

in the Z axial

direction for each

rotation.

To finish, machine

the entrance of the

hole.

Why Micro Thread Mills ?Why Micro Thread Mills ?

Coolant constaints

Standard taps have diffi culty machining nickel-basedalloys with water-soluble coolant.

Diversifi cation of work materials

Due to use of high-hardness materials exceeding50HRC,heat resistant steel, and even brittle materials,small-diameter internal threads are becomingincreasingly diffi cult to machine.

Description-Type Eff ect of tap root

diameter

Internal thread Thread shape after

tapping

Use

The work does not contact the rootdiameter of the tap during tapping

Taps normal internal threads, without causing the tap root diameter and the internal threaddiameter to come incontact.

Depending on the hole size, the work can come in contact with the root diameter of the tap during tapping.

Use it for tapping a hole of a size that isdiffi cult to control while controlling the inner thread bore. Controls burrs bysetting the thread engagement to 100% .When attempting complete top rolls, the internal threaddiameter may become too small.

The work come in contact with the root diameter of the tap during tapping.

Allow the tap root diameter and the inner thread bore to come in contact in order to prevent the inner thread diameter fromburring or cracking, and the inner borefrom burrs. Use it to prevent a bolt from galling during automatic assembly.The hole diameter must be strictlycontrolled.

UM-NRTUltra-small diameter nu-roll tap, starting with S0.5!

● A special thread form of the UM-NRT can produce high quality threads without less burrs.

● Check the forming condition in the same way as for conventional nu-roll taps.● Highly lubricating water soluble coolant or non-water soluble coolant is recommended for the coolant.● Select the machine and the holder with high run out tolerance.●Cutting conditions may change depending on the strength of the work material, machines, and the holders.●The formed thread has a small slit at the crest.

● Thanks to the high wear resistance and toughness of powder metallurgy H.S.S., stable tapping performance can be

● Its’ CrN coated surface has a low coeffi cient of friction, and excels in wear resistance and anti-fusing properties, ensuring consistent durability.

● Based on our experience with end mills, we created a rigid neck portion to resist breakage.

● Tool Material

Our in-house tests performed in soft steel, which is widely used in hard disk drives and

consumer electronic parts, resulted in tapping more than 10,000 holes.

A diff erence of φ0.01mm in drill hole size created a signifi cant diff erence in the durability of the tap.

Although this type machining is frequently performed in SPCC, this testwas performed in SS400.
