2258 Air Spring Conversion Kit

Converts torsion spring mini mills to air spring
Allows travel to the top of the column
Provides better support for the mill head

Convert torsion spring mini mills to air spring. Most mini mills use a torsion spring mounted on the side of the column to support the head. This air spring conversion kit provides all the parts required to change to a vertical air spring that mounts inside and above the column. With the air spring installed, you can move the mill head up until the top of the casting is almost flush with the top of the column. You can move it down until it almost contacts the adjustable Z-axis stop set in its lowest position. Besides all the parts required to mount the air spring, this kit also includes a longer Z-axis rack so you can take advantage of the longer head motion. This air spring has about 35 pounds of force. This is not enough to totally support the head, but it is a heck of a lot more support than the torsion arm provides.

4151 High Speed Spindle Kit, HiTorque Mini Mill

Fits HiTorque mini mills
5000 rpm top speed
Includes two pulleys and a belt
Belt is 350-5M-15, 70 teeth

These pulleys change the spindle speed range to 5000 rpm max. It's important to have high speed bearings, as the standard bearings are not rated to 5000 rpm. Most LittleMachineShop.com HiTorque Mini Mills have high speed bearings--see the Chris' Tips tab. The increased speed is great for small cutters such as those used for engraving. Just remember that doubling the speed will cut the torque in half. This high speed spindle kit uses the same belt as the standard drive pulleys. We do not have installation instructions completed yet, so you are on your own for installation. The pulleys are easy, but if you have to change the bearings you have to press the spindle out and back in. A hydraulic press makes it an easy task. Switching pulleys to the original set shouldn't take more than 20 minutes.

6538 Mill Table Stops

simple and reliable mechanical mill stop
2 table stops (left and right side)
Center bracket
Works on all HiTorque Mills

Similar to any mechanical stop, these table stops provide a simple and reliable mechanical mechanism to set a stop on both sides (left/right) of your table. These stops limit x-axis table travel on your mill. This can help in achieving repeatable cutting actions of a standard length along the x-axis. The 2 table stops are secured to the narrow channel on the front of the mill table via 6mm t-slot nuts. Depending on the projects needs these can be set anywhere along the length of the table. The center limit block is secured to the front of the mill using the pre-drilled holes provided and also commonly used to mount a limit switch if using an optional power feed. When moving the table in either direction the center limit block will stop table movement in a given direction when it reaches either stop. Similar to all stops this is the prompt you have reached that sides limit and should reverse direction or re-establish a new set-up.
