Samurai 120H 1.2kW BT30 ATC Spindle head

    The BT30 spindle head market for DIY milling machines is saturated with high rpm low torque spindles from China. These spindles are designed for routers to take light cuts in aluminum, however at Samurai our spindle head is designed to take large cuts in aluminum and steel. Other benefits of a high torque low rpm setup is the ability to drill holes, rigid tap, and use large diameter tools.

The Samurai Machine Tools 1.2kW Spindle head is a perfect upgrade for any small manual mill or DIY CNC machine.

This spindle has been designed for the Samurai 120 and therefore is very rigid, ATC ready and is the smallest BT30 spindle you can buy.

Benefits of BT30 over R8 or similar:

• Reduced Runout
• Increased Rigidity
• Fewer parts between the spindle and the tool
• No tool slippage
• No tool pull-out
• Cheaper toolholders
• Huge variety of toolholders (e.g. Hydraulic chuck or heat shrink tooling)
• ATC capable
• High torque capability
• Larger diameter tooling
• Tool changes in under 2 seconds are possible

 Technical Details

1.2kW Servo

We don't use VFD spindles at Samurai, we want the ability to cut like a full size machining center. This servo features 4nm torque which unlike a VFD, is consistent across the full RPM range. The ability to maintain position at low or even no speed allows for unique abilities that router spindles aren't capable of.

The servo drive features an alarm function that can automatically estop your machine if it detects a problem.

ATC Air purge

 If you would like to use an Automatic Tool Changer this feature is a must have. When changing tools there could be chips (swarf) on the toolholder that has come from machining operations and if those chips aren't removed before changing tools, the BT30 taper will be damaged and if you continue machining, the parts you make may be out of tolerance and have a poor surface finish.

Through spindle air

This machine features 6bar through spindle air, allowing you to blast chips out of deep pockets when milling or drilling.

6500 RPM

Unlike many spindles you may have seen, this is not a router spindle. It is designed to run on machining centers capable of holding large tools and taking bigger cuts, which requires lower rpm and more torque.

Note: New spindles may generate more heat as they require a run in period, this can take up to a week.

Spindle Lock

Locking the spindle rotation allows for broaching, mill turning, and other capabilities. 

Rigid Tapping

This spindle is capable of rigid tapping. It features a Proximity sensor on the spindle which can be fed back into the controller to measure RPM. It generates 2 pulses per RPM. The servo also features a 2500 line encoder with 48/22 pulley ratio to the spindle.

• 8mm 2m Silicone hose

Optional:

• 16 Position spindle rotation lock
• Z Axis / Column (with closed loop stepper)

Setup Support

Correct Use of Product

It is very important that this spindle is setup and used correctly otherwise it may cause damage or harm. There are many factors involved in getting this spindle to perform to an acceptable standard for a machine tool but here is a list of the basic things that need to be considered for safety / durability reasons:

• Correct wiring of 240VAC servo motor
• Spindle Temperature must not exceed 70°
• Must be ground (earthed) to the spindle and the rest of the machine (for safety, and ground faults can cause sparks that could cause premature bearing failure)
• The spindle must not be able to rotate while the drawbar is activated and vice versa
• Tools must be gently inserted into the taper to prevent damage
• Must not exceed values stated in the specification
• Spindle must not be rotated without a tool
