Micro-Mark 7x14 Version (09/08/02)

MICROLUX 7x14 HIGH-PRECISION HEAVY-DUTY LATHE Micro-Mark 7x14

 

Update 03/20/11 - The Micro-Mark 7x14 has been superseded by the 7x16 which is 2" longer and has the new, powerful brushless DC motor. Micro-Mark no longer sellls the 7x14 version described below.

Micro-Mark has announced new 7x14 lathe, and it looks pretty intriguing. While made by Sieg, it is quite differerent from any of the Sieg lathes offered by the other vendors. Here are some of the highlights that differentiate this lathe from the competition:

Tthe tailstock has a cam-locking feature similar to the one JW Early designed as a 7x mod.  Here are some photos that Dick Denby and Joe Schulte took at the Micro-Mark store in NJ:

Here's a report from Dick Denby:

Joe Schulte, myself, and a friend visited Micro-Mark's home office today to discuss and review their new 7X14 Mini- Lathe Model # 82710 @ $629.95. Their 7X12 Model Mini-Lathe # 82500 is now discontinued.The # 82500 previously had been on sale for $499.95,regularly $ 569.95. A difference of $ 130.00 old versus new.

Photo's were taken of the new lathe and its attachments. I have attached a view of the TS showing the cam lock. A later post will have several images, but I want to verify that my ISP (AOL) will not cause an issue with multiple attachments to a Yahoo site. I did not want to scale them down too much from the original resolution in case anyone wants to magnify them to view fine details. Besides the 7X10 minilathe group, I am copying to Frank Hoose for review at his minilathe. com web pages.

Bed Length Model old # 82500 = 25", Width = 3-5/16"
Bed Length Model new # 82710 = 27-1/2" Width = 3-5/16"

Measurement was taken by removing the head stock cover and measuring the bed casting end to end. No Bed Length conversion kit is planned for the old 7X12 units, as the new lathe has a 350 Watt DC (0.47hp) motor and it mounts differently on a pivot plate. We saw a rough draft of a new instruction book 8-1/2" X 11"illustrated with 25 pages that will answer just about any question from cutting tapers to gear selection to the most basic of questions. This will be an accessory which has application to owners of the old model 7X12's as well. A job well done on this needed material.

The tool holder does indeed have a clear pexiglass cover that would prevent chips from flying back at the operator. It is spring loaded so that it moves if the tool holder bumps against the head stock or some other object.

Now the tail stock cam lock looked and performed very well. Model number #82812 available in November @ $ 74.95. This will be the entire tail stock replacement unit with camlock and tailstock plunger ram marked with 1/8" increments. It will fit previous Micro-Mark lathes. Also confirmed to us was the fact that this lathe is a SIEG and accessories from previous models sold by Micro-Mark will fit the new # 82710 Lathe. All other info covered in Frank's update notice is accurate such as the tachometer etc. Color of machine "RED"

Here are some comments from Chris Woods of LittleMachineShop.com

The Micro-Mark 7x14 bed is actually 2" longer than a 7x12 bed. The headstock is also about an inch longer. It has a larger motor (probably the mini mill's 350W motor). One nice, but hidden feature is the motor mount. The motor is mounted on a pivoted plate, instead of the two studs through the casting. The carriage is the same as a 7x12, so the accessories, like steady rests and such, fit. I have a bed and a motor mount, but nothing else, so that's pretty much the extent of my knowledge. I can't get the tailstocks from SIEG, as they are a Micro-Mark exclusive. Expect to see Micro-Mark come out with a kit, like their True Inch kits.

Here are the specs listed on the Micro-Mark website:

Maximum swing over bed: 7 inches diameter

Distance between centers: 14 inches

Main spindle speeds: variable between 100 and 3,000 rpm

Spindle bore: .787 inch diameter

Compound slide travel: 2.165 inches

Tail spindle travel: 2.125 inches

Tail spindle taper: MT-2

Motor: 350 watt (0.47 hp) DC(operates from standard 110v AC wall outlet)

Thread cutting: 12 to 52 tpi in 18 steps

Overall size: 12-3/4 inches high x 12 inches deep x 35 inches long

Weight: 90 lbs. (basic machine, no access.)

MicroMark 7x12 Version

Update (03/30/11)
The Micro-Mark 7x12 and 7x14 have both been discontinued. They are superseded by the new 7x16 model.
End of update

Update (09/08/02)
This version has been discontinued and replaced by the new 7x14 model.
End of update

MicroMark sells a red 7x12 that looks similar to the the Grizzly 7x12.  One important difference, though, is that this version has true inch calibrated leadscrews which can provide more accurate dimensions when using the calibrated dials to advance the cutting tool.
