We offer a range of spindles to suit all types of dicing machine. These include flange mounted, gantry mounted and round bodied cantilevered spindle styles. Spindles may also be customised to individual requirements.

The spindles cover a full range of blade diameters from 50 mm (2 in) up to and including 101 mm (4 in). For 50 mm diameter blades, spindles have a maximum speed of 60 000 rpm and 1.2 kW of available power. Larger spindles for 101 mm blade diameters have a maximum speed of 40 000 rpm and develop 2.5 kW of power. DC brushless motors are fitted as standard to achieve maximum operating torque over a wide range of speeds. This makes our spindles suitable for cutting a variety of materials ranging from silicon through to quartz. AC motors can also be fitted to spindles to meet customer drive specifications.

Spindles are fully water cooled to minimise thermal expansion. They are designed and constructed for maximum durability. All spindle designs have been proven in heavy duty dicing applications.

Loadpoint can also fit electrical brushes for touch sensing circuits and supply balanced wheel mounts and spacers.

AC and DC drives specially matched to dicing spindle applications are available from Loadpoint. A spindle repair and retro-fitting service is also available.

What is an air-bearing dicing spindle?

An air-bearing dicing spindle is a high-precision motorized spindle used in the dicing process for semiconductor wafers, electronic components, and other materials. It utilizes air pressure to create a thin air film between the rotating spindle shaft and the bearing, resulting in ultra-smooth and frictionless rotation. 

How does an air-bearing dicing spindle differ from other types of dicing spindles?

Unlike traditional ball bearing or hydrodynamic bearing spindles, air bearing dicing spindles do not rely on physical contact between the rotating shaft and the bearing. Instead, they utilize a thin air film to eliminate friction, vibration, and heat generation, thereby achieving higher precision, improved surface quality, and reduced wear. 

What are the advantages of your dicing spindle?

Our dicing spindles offer several advantages, including higher accuracy, improved surface finish, reduced tool wear, lower maintenance requirements, and increased throughput. The frictionless rotation provided by the air-bearing technology allows for exceptionally precise and clean cuts. 

What types of materials can be diced using an air-bearing spindle?

Air-bearing dicing spindles can be used to dice a wide range of materials, including semiconductor wafers (such as silicon, gallium arsenide, and silicon carbide), ceramics, glass, and other brittle materials commonly found in the electronics and photonics industries. 

What are the materials are used in your bearings?

Stainless Steel, Bronze, Aluminium, Titanium, Plastics 

Can you customize spindles to suit all types of dicing machines?

Yes, we have the capability to customize spindles to suit a wide range of dicing machines. These include flange mounted, gantry mounted and round bodied cantilevered spindle styles. Please feel free to contact us to discuss your requirements and explore the possibilities of customizing a spindle for your dicing machine. 

Do you offer repair services?

Yes, we offer professional repair services for dicing spindles that experience issues or malfunctions. Our skilled technicians have extensive knowledge and experience working with various spindle models and brands. Whether it's our own spindle or a spindle from a different manufacturer, we are equipped to diagnose issues, perform necessary repairs, and restore optimal functionality. 

What do I need to run an air bearing spindle?

Air spec, controller, chiller etc. - GCM
