Frequently Asked Questions:
Question 1: What is the difference between the PM-833T, and the PM-833TV?
Answer 1: The PM-833T Machine is a Geared Head Mill, and has 6 different spindle speeds, in a range from 60 to 1500 RPM. The PM-833TV Machine is a Belt Drive Mill, and has an infinitely adjustable speed range from 50 to 3200 RPM.
Question 2: Is there any other difference in the machines, besides what is described above?
Answer 2: No, the body and all other components of the machine are exactly the same, the head is the only difference between the PM-833T and the PM-833TV. All accessories such as power feeds, stands, DRO, etc. are the same between both models.
Question 3: Which one is better for me, the PM-833T, or the PM-833TV?
Answer 3: It really depends what you are doing or think you will be doing. The PM-833T Geared Head will have more power at the lower speeds, so if you are doing a lot of larger, lower speed milling and drilling in Steel / Stainless Steel or similar materials, the PM-833T may be a better machine for you. (The 833T is still fine with cutting Aluminum and similar materials, no problem with that, you just have a lower spindle speed, so you may just have to go a little bit slower with feed rates, but it will still do the job just fine.)
The PM-833TV has more than double the top spindle speed of the PM-833T, and the PM-833TV is a belt drive, so it is quieter running at higher speeds. So the 833TV is a better choice if you are doing more higher speed aluminum cutting and want to get maximum feed rates, but it still has plenty of power at lower speeds for any type of general purpose work in steel, stainless steel, cast iron, etc., just not quite as much power as the 833T at lower speeds.
Either machine can do any materials that you can machine on a mill just fine, some things are just more suitable for one of the particular models.
