Belt drive or gear drive really doesn't make too much difference if you are running a samll milling machine. Most of the time you will be in open belt drive. The back gears on a B'port type mill are useful for slowing the spindle down when using big drills or fairly large diameter end mills in tough steel.

The CNC belt drive conversion kit includes one belt. Change speeds without any tools. Simply remove the guard, loosen the lever locks and move the belt from one pair of pulleys to the other. Low speed range is 0-1700 RPM. High speed range is 0-4300 RPM. The installation is bolt-on and takes about 20 minutes.

Re: belt drive vs. gear drive lathe. Belt driven lathes are usually capable of a better surface finish, for two reasons. The belt keeps motor vibrations away from the spindle. And the many gears and bearings in geared headstocks can introduce their own vibrations, especially if not precision ground.

Mini Mill Belt Drive. This is all about making a mini mill belt drive for the gear driven mini milling machine. A great upgrade that will result in a quieter and smoother milling machine. These mini milling machines (eg Amadeal XJ12-300) with the back gears suffer from gearbox failures and mine did some time ago – read about the experience of ...

Fits all HiTorque Mini Mills and mini mills with a 300 mm x 130 mm table. This kit adds one inch to the travel of the lathe cross slide on 7x10 and 7x12 mini lathes. These are SIEG C2 and C3 lathes.

03-17-2009, 04:49 PM. I have used both gear head and step pulley type mills. Each has its own advantages. More important that drive type is the ability to change setups easily. A dovetail column mill or a knee mill are much easier to work with when changing setups than a round column mill.

A Mazak QT-20 lathe runs 120mm ID bearings on the spindle and has a spindle bore of 2.44″. That works out to a wall thickness of about 1.142″ or about 29mm. Now let's say we want to build a lathe spindle with a spindle bore of 2″. Let's give it a 1″ wall thickness, so we need bearings with 4″ ID which is 101mm.

On the plus side it's quick and easy to change gears. Range of speeds are very wide, 30 to 2500 rpm with no funky procedure to engage back gear. Belts are very simple and very robust to abuse. Harder and slower to change speeds with a more limited rpm range. Belt driven lathes usually use a backgear to achieve slow speeds.

The spindle of this machine is driven by a four-step cone from a two speed countershaft; being back geared, it has sixteen changes of speed. The feed is driven through a four-speed gear train and a belt running on a four-step cone, giving sixteen changes in the rate of feed, ranging from 0.004 inch to 0.100 inch per turn of spindle.

However, I notice that the PM-727M is a gear driven system. So again, not having any actual experience in this area, I'm reaching out for some advice on these two mills. I'm pretty sure that the smaller PM-25MV will perfectly suit my needs and apparently the belt drive is smooth and enjoyable to work with.

As Butch said "99%" of all his tasks are on a small machine. I believe that the Gear Head machines are a step above the belt driven heads on the small machines and from the photos I looked at the PM and Grizzly machines with identical features are probably made in the same factory in Taiwan just different paint.

The belt used with the variable-speed pulley has a V-shaped cross-section that matches the angular faces of the movable pulley flanges. As the flanges open or close, the belt is forced either up or down in the pulley.

Mill drills are an alternative to a milling machine. These combine a belt driven drill press with the dual coordinate abilities of the milling machine's table for flexibility and efficiency. A locking collet prevents the cutting tool from falling away from the spindle when lateral forces are experienced against the bit. The JMD Milling Drilling ...

Torque: First and foremost, without a reduction (like that in our belt drive systems), you will lose the mechanical torque advantage these systems provide. As an example, for a motor putting out 300-oz*in of torque, with a 1 inch pitch circle gear, a direct drive system will put out about 37 pounds of force, compared to over 100 pounds with our ...
