Okuma Lathe Machine Manual
I'm looking into adding a CNC lathe into my small shop. I do mostly prototyping and occasional very small lot (.
I have one of each, a Genos L200emy and a TS4000YS. Takisawa's manuals are a single sad engrish binder. Okuma comes with basically a whole bookshelf. Takisawa has a plain vanilla Fanuc control with no operator help or overlay. The Okuma control is great, except that is is in some places intentionally crippled and then they sell you basic fublnctionaliry back as options.
Options are expensive. If you ask Yamazen about literally anything on the Takisawa, the answer will be 'I don't know' and that is where it will stop. At least in Ohio.
Which is less than helpful because the book is worthless. Takisawa's office in this country are somewhat helpful though. Which is a shame, because the guts of the Takisawa are pretty good, really. I described it as an underengineered and underdocumented assemblage of pretty nice parts. I use the Okuma daily.
If you have a lot more space and a lot more budget I'd happily sell you a barely used three year old Y axis Takisawa with sub-spindle. It is far and away my least favorite machine in the shop. (In fairness, it is also the only Fanuc control in the shop). We have an Okuma L250. The control is the best on the market IMO, but that particular machine is direct drive, and has NO balls at 5' or larger diameter stock unless you take small (.1' or less per side) cuts. Someone above said it takes forever for the spindle to wind up and down, that's not the case with ours, unless they are used to Brother mills lol. The way oil consumption can be controlled by a parameter if need be.
Overall it holds tenths all day long. I would recommend it.Thx Did you ever need any support for your Okuma? I'm looking into adding a CNC lathe into my small shop. I do mostly prototyping and occasional very small lot (.
This equates to 'don't crash it'. A few models of Hitachi Seiki used a similar system. After a heavy crash they no longer would 'lock' the turret at that index. Left you with a choice of a $7k parts bill plus labor or a turret station that was great for tapping or reaming.lol.
A T series Hardinge is about $180k to $200K or dinky gang tool QUEST CHNC 27 & 42 is freaking expensive too. $7k for a willfully bad crash sounds pretty good value to me and one to budget for Awesome! it is what it is No freeeeeee lunch. OP is doing small batches and has time to be baby the flump out of such a machine. However I do feel that the POWER of the spindle vs the mechanical solidity of the turret is a mis-match and yes the spindle + freaky soft jaws + long hunky tool could be 'fun'. Is there not a friction break release system (on the turret) that just 'Gives' in the event of a really hard hit? Is it 'Cheap to crash' is also a good criterion for shopping for new equipment.
What happens if you have never crashed anything in your entire life? Telford Einstizle not withstanding. (A few bumps?). If 'cheap to crash' was the only 'Controlling' criterion we would only buy 5 axis robo drills and nothing else.
Not sure what lathe / turning center is best for repeated crashing OR BAD crashing? Sounds like the beginning of a bad blues song. 'Got up this morning Dun nahh neh nahhh cra-cra-craaashed my lathe, Duh nehhh nah naaa, Boss man looking to fire me Dun nehh neh nahh cuz I crashed it twenty times before, Duh neehh neh nahh Got up this morning '.
Communications Between Turning Machine and Bar Feeder Reduces Material and Labor Costs. Outsourcing production of critical parts was putting a crimp in plans to move from strictly distributing products made by other companies, to making and selling some of their own. Machining these parts in-house required taking their first steps into the worlds of automation and the Industrial Internet of Things. The 75-year-old, family owned business based in Lewis Center, Ohio distributes testing equipment used by construction, laboratory, food service, pharmaceutical and other industries.
Cnc Lathe Machine Operating Manual
Recently Gilson developed a new product that separates particle sizes of granular material. This device is used by departments of transportation, civil engineering firms, and others that perform aggregates testing for construction projects such as buildings, roads and bridges. Although rotary sifters have been around for many years, Gilson’s product is completely redesigned and uses upgraded materials to provide quieter, more efficient and reliable operation.

As sales volume increased, the company decided to bring previously outsourced part production into its fledgling in-house manufacturing department. Gilson’s Vice President of Manufacturing, Phil Babka, explains, “Until 5 years ago we were strictly a distribution company and, in fact, we currently manufacture just 2 – 3% of the products we sell. However, we’ve identified certain items that we can make ourselves to reduce costs, improve quality and better manage our inventories.” Gilson makes three versions of its rotary sifter. Each model requires six, 5/8” stainless steel rods of various sizes, each of which has its own unique features. Babka recognized that bringing production of these parts in house, and realizing the desired goals of cost-efficiency and superior quality would require a new manufacturing approach. “When we first set up our machine shop we bought some used equipment including a manual lathe, manual milling machine, an older and a CNC cutoff saw. Using our existing equipment to make these rotary sifter rods would mean stationing an operator at the CNC lathe all day to constantly load material, run a part for about 30 seconds, take the part out and do it all over again.
As sales began to take off, we realized that we needed a more cost-effective method capable of pumping out thousands of these parts.” On a visit to a friend’s sheet metal fabrication shop, Mr. Babka observed an automated process that continuously feeds sheets onto a laser cutting machine, enabling lights out production. “Right then I knew what we needed.” Mr. Babka contacted a number of machine tool suppliers and explained his requirements, “I wanted to be able to run production with minimal operator involvement during the day and run unattended overnight. So we needed to continuously feed material into a machine tool that could run the various part programs on its own, and then automatically unload the finished parts.
The people who came up with the best solution were the applications engineers from Gosiger, Inc.” To meet Gilson’s requirements, the Applications Engineering staff ran a series of time studies to determine the most effective combination of equipment. Since lights-out production involved a large family of cylindrical parts, it was essential that both the machine tool and the material feeding system could automatically changeover from one part to another without operator assistance. And then there was the matter of automatically unloading the finished parts. The solution Gosiger devised was a fully automated cell consisting of 4 components:. Anthat uses a chain-driven loading rack holding seven, 6-foot long bars for diameters from 3/8” to 3 – 1/8” through a single guide tube that provides the support necessary for machining at high spindle speeds. An CNC lathe equipped with a subspindle, live tooling and the open architecture, Microsoft Windows-based OSP control that enables integration with both factory management software and peripheral devices. An that automatically removes parts through the back of the secondary spindle after both ends have been machined.
The coupled with the Okuma Thinc API that enables the sharing of data between the LNS bar feeder and the Okuma OSP control to maximize production efficiency and material usage. In operation, the machine attendant fills the LNS bar feeder’s loading rack with 6-foot bar stock, selects the part programs to be run using the Okuma OSP control’s master schedule function, and starts the process. The bars are automatically fed into the turning machine’s main spindle for primary machining, then the part transfers to the sub-spindle for secondary operations. When the part is completed, the Blaze Air uses vacuum suction to unload the part through the sub-spindle and deposit it into its storage tray. All of this proceeds automatically with no operator intervention. In addition, the LNS e-Connect system, coupled with the OSP master schedule function, makes the process even more cost-effective through its ability to automatically changeover from one part to another on the fly, and manage material usage to minimize waste. A part library built into the LNS Quick Six S2 stores all of the bar feeder parameters for each of the part programs, and tracks material usage.
Via e-Connect, the bar feeder communicates these data to the Okuma lathe’s master schedule to determine which part to run, based on available material. The master schedule looks at how much material there is and the various part lengths. It then determines if there is enough material available to run the required quantity of a particular part run. If so, it runs the complete batch of that part. If, however, there is not enough material for the entire run, the system determines the length of any remnant, calls up the next part in the schedule that it can make from the remaining stock, and the lathe and bar feeder automatically adjust to make the new part.
Once the 6-foot bar is consumed, the bar feeder loads the next bar and the system repeats the process until it makes all of the various parts in the production schedule. The e-Connect system also uses the bar feeder’s built-in Web server to access the Internet, provide reports, and enable remote monitoring of the system.
All of this makes unattended and lights-out operation possible. According to Phil Babka, the cost of producing these parts in-house is about 25% of the cost to have them made outside.
Equally important, thanks to the LNS e-Connect system and Okuma OSP control, material costs dropped dramatically – by more than 75%. He calculates that the entire automated work cell will pay for itself in approximately 5 years. “We’re very happy with this system and are planning to add another in the near future.
My advice to any shop that is considering an automation system is to make sure that, not only is the technology a good fit, but that the people you do business with will support you throughout the process. We couldn’t be happier with the applications engineers and others at Gosiger who worked with LNS to come up with exactly what we needed. Both the Gosiger and LNS teams were there whenever we needed them through installation, training and tweaking the system. I’d never heard of a Blaze Air until Gosiger suggested it, and it’s the perfect solution for unloading these parts. Likewise, the LNS e-Connect system was new to me and saves us additional time, labor and material costs.”.
