FAQ about Milling Tools

Do you provide customized services of milling tools?

Of course! We furnish non-standard customization beyond standard sizes according to your personalized needs. Factors like materials, diameter, flute length, and the choice of coating of JINOO’s milling cutters can all be modified to meet your exacting requirements, and we will offer you the cutting-edge solutions to ensure the outstanding user experience.

What is your MOQ (Minimum Order Quantity) of milling cutters?

For our standard size of milling cutters, we have a minimum order quantity of 5 pieces. Beyond that, if you want JINOO to customize milling cutters for you, there’s generally no minimum order quantity for non-standard tools, and even a small order can be accepted.

How to choose milling tools for my applications?

Identify the machining operations.

The coating technology and milling tool geometry should be selected based on the specific workpiece material.

Aluminium & Non-ferrous Metals: You can choose uncoated carbide milling tools or polished milling tools with sharp cutting edges.
Steel & Alloy Steel: Milling tools with higher edge strength and nanolayer coatings like AiTIN and TiAIN are recommended.
Stainless Steel & Titanium: Solid carbide milling tools with heat-resistant coatings will be suitable.
Cast Iron: Indexable tools and CBN-tipped tools with high wear resistance can be used.

Evaluate the Machining equipment

Standard milling cutters are suitable for vertical machines, and extended tools can be used for horizontal machines. When it comes to CNC machine centers, high-precision tools can achieve tight tolerances.

Performance Requirement

If you need superior hole finishes with high accuracy, ball nose end mills or finishing end mills will be better. Solid carbide milling tools with high rigidity and advanced coatings can achieve longer tool life. Roughing and high-feed end mills are designed for high chip removal rates.

How to extend the lifespan of milling tools?

Select the right milling tools for your application, match the tool geometry and coating.
Use the appropriate feed rates and spindle speeds for high-feed machining. Use the proper cutting depth (ae & ap) to avoid overloading.
Ensure adequate lubrication and cooling with suitable holding to minimize vibration and deflection of carbide end mills.
Keep maintaining and tracking the CNC milling tools’ life. Remember to proactively replace milling tools and apply regrinding to ensure performance.
Store milling cutters in a dry and clean place.
Use advanced machining strategies, optimized chip thickness per tooth instead of average, and apply toolpath simulation to avoid sudden breaks.

What coating types are recommended for milling tools?

It depends on your workpieces and machining requirements.

For General Steel Processing

BALIQ ALTINOS, DURANA, TISAFLEX, PERTURA, and LATUMA are great to be applied in milling tools.

Stainless Steel / High-Temperature Alloys

BALINIT DURANA, BALIQ TISINOS PRO, TISINOS, MICRO ALTINOS, ALCRONA EVO.

Mould Machining / Dry Cutting

BALIQ ALCRONOS, HELICA, and ANTO are suitable for milling tools.

Composite Materials / Aluminium Alloys

BALIQ AUROS, BALINIT MAYURA.

High-gloss Precision Processing

BALINIT MAYURA and ANTO are suitable for application in the milling tools.

How to use a milling tool?

Choose the suitable milling cutter type, such as end mills or face mills, for specialized application scenarios.
Secure the workpiece firmly to ensure the correct alignment of milling tools in the spindle.
Set the proper cutting parameters according to the workpiece material.
Use the coolants or lubricants properly to extend the tool life and promote the chip flow.
Follow the professional strategies in high-speed milling to deliver high precision.

What’s the main purpose of milling?

Milling is aimed at using carbide end mills to remove material from the workpiece to produce accurate surfaces and shapes. They are widely applied for slotting, contouring, and machining flat surfaces. Milling is crucial for industries where high-dimensional accuracy counts, and manufacturers can achieve tight tolerances and superior surface finishes based on the cutting-edge CNC milling technology.

What are common milling mistakes?

Using incorrect cutting parameters and milling tools.
Using too fast or too low spindle speeds will lead to milling tool wear and tool breakage.
Excessive cutting depth may lead to milling tool vibration and poor surface quality in CNC milling.
