The 5500-series mills are essentially a Model 5000-series mill upgraded to include adjustable “zero” handwheels in place of the standard non-resettable handwheels. They feature the same solid 10″ (254mm) aluminum base, precision machined dovetailed slides with adjustable gibs, permanently lubricated spindle bearings, adjustable preload anti-backlash feed screws on the X- and Y-axes, and many other features found only on the best commercial machines.
Adjustable zero handwheels allow the user to reset the handwheel to a zero reading at any time without moving the leadscrew. This makes dialing in the next dimension easier, as you are starting from zero each time. It also helps eliminate math errors. This is a feature normally found on expensive full-size machines, but not often available on a machine of this size and price. The 5500/5510 mill combines the compact size and economy of our basic mill with the luxury of adjustable handwheels.
Notes on ordering a metric mill
Most of our cutting tools, like center drills, are manufactured in a fractional size. If you have a metric machine with metric holders, like collets or end mill holders, you will need to order fractional holders to accommodate our cutting tools.
- A powerful 90V DC motor with electronic speed controller
- 10″ base
- 2″ (51mm) resettable “zero” handwheels on the X- and Y-axes, and one 2-1/2″ (63mm) resettable “zero” handwheel on the Z-axis. Each handwheel has laser engraved aluminum handwheel collars
- 2.75″ (70 mm) x 13.0″ (330 mm) table with two T-slots
- Pulleys, drive belt, three hexagonal keys, spindle bars, gib removal tool, eight-foot three-wire power cord, and instruction manual
- Oil reservoirs on the X/Y axes and the Z axis to help keep critical parts lubricated. These were initially developed for CNC machines that run constantly for hours on end but can benefit manual machines as well.
- Brass leadscrew cover that keeps chips off the rear of the Y-axis leadscrew.
