Boosting Profits from Swiss-type Machines by Better Use of the Sub-Spindle

Be sure to join Matt Saccomanno, President of Masa Tool, presentation on boosting profitability by taking advantage of improvements in sub spindle workholding on Swiss-style CNC Machines.

IMTS Conference: Boosting Profits from Swiss-type Machines by Better Use of the Sub-Spindle

This is a presentation of new and advanced techniques for gaining productivity from Swiss-type CNC machines, with emphasis on maximizing utilization of the machine’s counter-spindle (“sub-spindle”). Essentially a fully capable machine within a machine, the sub-spindle is rarely used at more than 20% efficiency, which is a huge waste of productive capacity.

Most of the roadblocks to increased usage stem from the limitations of traditional workholding. The presentation is loaded with real-life examples and practical do-right-now techniques.
Swiss-type CNC turning centers are gaining in popularity as the parts they produce trend toward higher precision and micro-sized features. To be competitive, smart use of the machine’s full capabilities is a big advantage. Achieving “lights out” production and minimizing machine cycle times are key tactical objectives.

Join Matt Saccomanno, co-founder and CEO of Masa Tool, as he explains advanced work holding techniques that fundamentally change the scope of what is possible on a Swiss-type machine (also known as “sliding head” or guide bushing machine). Balancing the main and sub-spindle cycle times, achieving reliable untended , lights out production, and reducing scrap and down time will be the focus of this informative and interactive presentation.

Much of this material is also applicable to other types of machining centers, especially when making small parts. Bring your real-world “problem parts” to the session for a strategy discussion with Mr. Saccomanno. This session is beneficial for machinists, CNC programmers, manufacturing engineers, tool crib personnel, and hands-on managers.

About the Speaker

Matthew Saccoman no Masa Tool Founder CEO IMTS Conference Speaker
Matt Saccomanno has over 4 decades experience in Swiss-type machining and related fields of product design and engineering.

​Working as production operator, set-up machinist, manufacturing engineer, product design consultant, inventor, and company founder, he has met challenges from every direction in the vital and amazing field of precision manufacturing.

Matt co-founded Masa Tool Inc. and invented the Microconic system.

About Masa Tool Inc.

With deep roots in the Swiss-type screw machine industry, Masa Tool Inc. was founded in Oceanside California with the mission of bringing the Microconic System to the world. This revolutionary workholding system consists of the Microconic “cartridge” and “collet”. It was invented to solve the problems created by traditional long nose collets commonly used in the sub-spindle of screw machines for over 100 years.

As screw machines evolved from mechanical cams in the late 1900’s to today’s CNC controls, the complexity of parts being made increased dramatically. Making these modern micro precision parts complete on the machine without additional secondary operations became critical to remain competitive. Using the machine’s sub-spindle to complete the part is a must.

As the demands for precision and complexity increase, the traditional long-nose collet has many limitations that can frustrate the machinist trying to get the most out of the machine.

We created the Microconic system to overcome these limitations of conventional collets. The result is superior rigidity, accuracy, over-grip capability, clamping force control, and long-run stability.

We at Masa built our company from the ground up to ensure that everything in our catalog is available to ship within 2 days. Every size, every type. We currently offer any size from 0.2mm – 10mm diameter (.008” - .394”).

Workholding Advances: Microconic helps Customer Broach a Dental Implant on the Subspindle

Microconic helps Customer Broach a Dental Implant on the Subspindle
Workholding Advances
Medical parts are often delicate, which can create problems when they are picked off with the subspindle for backwork. It is important but difficult to apply just the right amount of pressure to hold the part in the subspindle. And once the optimum gripping force is determined, it is not easy to communicate to other operators how the adjustment was made.

​Machine tool accessory maker Masa Tool Inc. (Oceanside, CA) has developed a collet system that makes this process easier. The collet is set using a special tool with marked graduations that enable precise adjustments to the gripping force of the collet.

“You can document the micrometer-like adjustment for the collet closure in your setup plan,” said Matt Saccomanno, CEO.  “It’s done the same way every time, regardless of operator skill and without relying on feel.”

One of the more challenging Swiss applications is making dental implants because of their small size. Saccomanno said that Masa recently helped a customer broach a dental implant on the subspindle with the Masa collet system holding only a small land. Considering how much force is applied to the workpiece during a broaching operation, this might have seemed impossible to accomplish.

The reason it is possible is that the Masa collet system applies the gripping forces directly over the area where the collet grips the part. The collet system has two main parts, a cartridge that replaces the standard machine collet and a smaller collet made by Masa that is installed into the cartridge. These components are held to a high accuracy and are made by Masa with proprietary grinding methods. Concentricity variation is held to 0.0002″ (0.005 mm).

“This particular broaching application used an over-grip collet,” Saccomanno said. “The process change moved an operation from the main-spindle to the subspindle and so allowed some simultaneous machining not possible previously. Before they used our system, the part was made entirely on the main spindle.”
​
An over-grip collet opens up to pass over a shoulder or some other feature on a part in order to grip the part past the shoulder. Masa makes over-grip collets that can open up to 4 mm over the chucking diameter. This is the largest difference in diameter in the industry and still holds 0.0002″ TIR, according to Masa.
