Machine Components

Control & Drive System
UTEC machines are equipped with the latest technology of FANUC, the world-wide leader of control systems for machine tools. The FANUC 0i-T* 2-axis control and the iServo-Drive System offer a state-of-the-art, high precision machine control system with high efficiency and reliability.

Tool System UT400E
The turret disc on the UT400E model comes with a fast insert clamping system for up to 12 tools and guarantees a fast tool change.

Tools & Holders
The quality of cutting tools is of highest importance in the production of lathe-cut seals. A complete set of high-precision cutting tools made of fine-grain carbide is supplied with every UTEC machine. In order to cover the complex, complete range of existing seal profiles, most tools have a special geometrical shape and are custom made for seal production.

Material Clamping System
In order to efficiently clamp the raw material billets, special clamping jaws are mounted on to the steel body of the high-precision 3-jaw machine chuck. These sets of multi-range clamping jaws are made of high-grade aluminum and are designed to clamp certain diameter ranges of semi-finished billets.

Chip Cutter & Suction Unit
A well working chip cutter and suction unit play an important role in the manufacturing process of seals and engineered plastic parts, as they contribute to preventing swarf buildup around the tool and thus to a better surface finish of the end product.

The chip cutter is made of high-grade aluminum, using HSS tools to hack up the chips and keep the tools clean for optimal machining performance.

Optional Accessories
UTEC recommends the Accu-Finish tool lapping machine in combination with a microscope to sharpen, and verify the state of, tool tips.  This tool lapping technology is highly efficient, as it substantially increases the service life of a cutting tool, and guarantees optimal tool sharpness, which in turn assures excellent surface quality of your end product.

Other accessories, such as measuring devices, bevelling shears, band saws for cutting guide rings etc can be supplied on request.

UTEC “Flex” Software

The production software is developed in-house by UTEC engineers and underlies continuous updates, upgrades and improvements. Each of the more than 180 standard profiles can be easily modified by the user in the "Flex Mode" without the need to make modifications to the NC program itself.

The production process for seals is fast and easy:
1. Select your specific seal from one of the profile groups (wipers, rod seals etc.)
2. Key-in the nominal dimension of the seal as required (any modifications of dimensions can easily be made in the "Flex"-mode).
3. Select the sealing material and billet size from the drop-down list.
4. Suitable cutting tools will be proposed and the NC-program is generated automatically in the background.
5. Transfer the production date (CNC file) to the control unit
6. Set up the CNC machine for production and start the machining process.

This way, and endless number of seal profiles and dimensions can be manufactured. This is what makes lathe-cut seal manufacturing technology the most versatile in seal business.
