Joined. Oct 8, 2009. Location. Portsmouth, NH. Dec 31, 2009. #5. I'm going back and forth from ACER & SHARP milling machines to buy. I like both but with the ACER E-Mill you can get the AC frequency inverter drive that will let me run single phase power on 220 Volt. I do not have three phase power at my location.

Especially if the mill has a DRO system, I can think of very few reasons NOT to want ball screws and many reasons TO want them. I vote for them. CJ . L. Lakeside53 Stainless. Joined ... Any machine less than 50% efficient can't run backwards - i.e., the table won't move the screws. Ball screws are over 90% efficient; IIRC threaded screws ...

Check for movement between cross slide and carriage with the pry bar. Movement in X could be loose bearing housing(s), loose ball nut housing on carriage, bad or loose thrust bearing, bad ball nut or worn ball screw. Check for movement between carriage and bed with pry bar. Movement in Z could be same reasons as for X.
First, not all 2-30 Gorton mills are tracers or have ball screws. I have a 2-30 in our production area and it is not a tracer (never was) and does not have ball screws. The good is that the machine is 5 HP and solid, it has feeds in all directions run by a DC motor, mine has power knee elevation.
The difference in friction, rolling friction of the ball screws and the sliding friction of the acme screw is the problem using ball screws on a manual mill. The acme screw was designed to not rotate under load and therefore will hold a vertical load in place or from pressure from cutting forces.
Power Screws and Ball Screws are analogous to bushings (sometimes called plain bearings) and ball bearings. Like ball bearings, Ball Screws exhibit low friction and predictable service life. Screws, nuts, and balls are made of heat-treated steel to optimize performance and resist Hertzian stresses. Efficiency for these screws is 90% and does ...

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical ...
Our mills are similar, but not exactly the same, the X-Axis lead screw on mine is 22.12mm diameter 104.5 mm long The bronze nut is 34.7mm tall, however the table appears to have about an additional 1/2" of clearance to the nut, so the mounting block looks ( need to measure) like it could be about 1.8 or 1.9" tall.
These are used in many applications across many industries. Let us assist you in engineering your machine tool for a rotating ball nut design. Call 248.541.2333 Today visit our faq page for more information. The ball screw assembly consists of a screw and a nut, each with matching helical grooves, and balls which roll between these grooves.

Howdy folks, Some time ago I acquired a 1962 1-22 Tracemaster mill with a B360 3D True-Trace unit, in unknown working condition. According to the successor corporation that owns the rights to True-Trace, the tracer valve is totally obsolete and no parts are available. Based on a read of some...
Ball screws make the machine too "slippery" to me for lack of a better term. There is no servo holding the screw on a manual and creeping up on a number is easier with the built in inefficiency of the acme. I did think it a great idea once, threw the ball-screws away and went back. Everyone on the floor hated it so dumpster bound.
About the 14″ Base CNC-Ready Mill with Ball Screws. This machine is based on our 14″ 2000-series mill. The 14″ mill base with ball screws comes with all-new saddles developed for the ball screws and #23 NEMA frame stepper-motor mounts with high-torque couplings. The X/Y-mill saddle has been beefed up to accommodate the larger ball screws ...
Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start ball screws and nuts, they have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts. To ensure compatibility, select …
