Super Radius Mill TD4N Type, Modular Type

 

Product features and specifications

Basic specifications and features of the product

The cutting edge shape was reviewed for TD4N so that uncut remnants are reduced.

● Chip breakers for different applications and economical 4-corner-use inserts

·Features of insert chip breaker

● Easy-to-use large tip diameter

The TD4N has a larger tip diameter to reduce the generation of uncut remnants that tend to leave on the bottom surface of machined areas. The cutting width (ae) can be set to a large value, effectively improving machining efficiency.

It reduces the occurrence of sudden troubles due to cutting chip jamming. It enables further improvements in machining efficiency.

AJ coating series

Uses a new composition of AlTi-based film with a high AI content.
High abrasion resistance, chipping resistance and heat resistance.

Micro-grain cemented carbide with well-balanced abrasion resistance and toughness and the new "AJ coating" have improved abrasion resistance and chipping resistance.
It is highly versatile and provides high abrasion resistance and chipping resistance in cutting of steels in the range of 30 to 50 HRC.

·Grade for processing stainless steel materials JM4160
A micro-grain cemented carbide base material with excellent toughness and the new "AJ coating" have improved abrasion resistance and chipping resistance for cutting stainless steel materials.
The "AJ coating" with high chip-weld resistance has reduced the chip welding of work materials that occurs in machining stainless steel-based materials.

·General purpose for steel JS4045
A coating film with high heat resistance has reduced the crater wear that occurs in high efficiency milling.
A highly heat resistant cemented carbide base material reduces the progression of wear and provides high tool lifespan.
Especially in dry type machining, it has a long lifespan.

Performance/test information

(1) Reduced machining time

(2) Improved tool lifespan

(3) High efficiency milling under weak clamping rigidity

Recommended cutting conditions

Recommended cutting condition table

• This cutting condition describes the rotational speed, feed rate, and cutting amount for each work material (general steel, steel alloy, heat-treated steel, high-hardness steel, stainless steel, aluminum, cast iron, etc.) based on the manufacturer's recommended conditions.
• Optimal machining conditions vary depending on the machining environment (machine tools, tool holder, etc.); therefore, please check the machining conditions (machined surface, chattering, etc.) and make corrections during use.

Precautions for cutting conditions

(1) Use an appropriate coolant according to the work material and machining shape.
(2) This cutting conditions table gives an indication of the cutting conditions for shoulder milling.
In actual machining, please adjust the parameters according to the machining shape, purposes, machine used, etc.
In particular, when the cutting chip discharge or vibrations is a problem in machining with or close to groove cutting, please adjust the cutting conditions as follows.

• Reduce the depth of the cut ap to 50 to 70%.
• Reduce the rotational speed n and table rate Vf to 50 to 70%.

(3) Please note that the GX coating and JS coating do not cause a reaction to energized touch sensors.
(4) Be sure to remove cutting chips by air blower etc., to prevent tool damage due to chip clogging.
(5) Replace the insert as soon as possible to prevent damage due to excessive use.
(6) The following equation can be used to determine the cutting chip discharge per unit time Q:
Q (cm3/min) = ap (mm) × ae (mm) × Vf (mm/min)/1,000 Do not set values higher than the maximum value.

 

Compatible work material

• Carbon steel / steel alloy < 30HRC
• Steel alloy / tool steel 30 to 40HRC
• Pre-hardened steel / steel alloy 40 to 50HRC
• Stainless steel SUS
• Cast iron FC, FCD

● Precautions for creating a machining program

·In CAM, define the tool shape as the corner radius shape of R2.0.
·For the axial-direction cutting depth ap, use 1.0 mm or less.

Safety precautions
1. Precautions for handling

• When removing the tool from the case (packing), please take care not to injure yourself by dropping the tool on your feet or the tips of your bare fingers.
• When setting the insert and actually using it, be careful not to touch the cutting edge directly with your bare hands.

2. Precautions for installation

• When using the insert, set it firmly, and mount it on the arbor etc., securely.
• If abnormal vibrations or other problems occur during use, stop the machine immediately and remove the cause of the vibration.

3. Precautions for use

• Check the dimensions and direction of rotation of the cutting tool or work material in advance.
• Please use the values in the standard cutting conditions table as a guide for starting a new work. If the cutting depth is large or the rigidity of the machine used is small, adjust the parameters appropriately according to the properties of the workpiece.
• The insert is made of a rigid material. It may be damaged and scattered during use. Cutting chips may also be scattered. These flying fragments may cause cuts, burns, or eye injuries to operators. Install a safety cover around the tool and wear protective glasses or other protective gears while using the tool for securing the operation under a safety environment.
• Do not use the tool in areas where there is a risk of ignition or explosion.
• Do not use water-insoluble cutting oil as it may cause a fire.
• Do not use or modify the tool for any purpose other than its intended purpose.
