MONORAIL MR Standard

High rigidity, great dynamic and static load carrying capacity, outstanding running smoothness and the total enclosure of the carriage are the main features of the MONORAIL guideway. These properties result in higher machining rates while enhancing geometrical accuracy and surface quality of the machined workpieces. Our highly rigid MONORAIL provides improved vibration behavior, smaller vibration amplitudes and thus extends tool life.
SCHNEEBERGER has systematically applied its many years of experience in the design, production and use of roller-type anti-friction guideways in the development of the MONORAIL. Consequently the MONORAIL MR is a cost-effective anti-friction guideway which meets the challenge presented by modern machine design.

MONORAIL BM

SCHNEEBERGER's MONORAIL BM ball guideway features excellent dynamic properties and many commercial benefits. Designed with a small number of cleverly arranged components, it provides for excellent running properties due to the small number of transitions in the ball tracks, which lead to very quiet running, low pulsation and low friction as well as high travel speeds. The use of a trapezoidal rail section results in an extremely rigid guideway coupled with a substantial reduction in servicing time as additional wipers can be changed without dismantling the carriage. Complete sealing of the carriage guarantees maximum reliability coupled with a long service life. This robust and economical guideway rounds off SCHNEEBERGER's range of products for industrial applications with high demands on speed, reliability and consistant running properties.

MONORAIL BZ

SCHNEEBERGER's MONORAIL BZ systems are high-precision linear guide systems with integral rack drive, based on the company's proven MONORAIL BM profile guideways with balls. The benefits resulting from the integration of a profile guideway and an extremely precise rack drive mainly come into their own in the handling and automation industries, in laser and water-jet cutting tools as well as in woodworking machines. Outlay on the production of machine beds, the installation and alignment of the guideway and gearing are substantially reduced. Single piece rail systems are available up to a length of 6 metres.

The design of the MONORAIL BZ provides for superb operating characteristics, high load-bearing capacity and rigidity together with a long service life thanks to the use of the tried-and-tested MONORAIL BM profile guideway and to the high transmittable forces, smooth running and optimum positioning accuracy offered by ground, hardened and precise helical gearing of superlative quality.

MINIRAIL in 8 sizes according to DIN standards

All installation and connection dimensions are in accordance with the DIN standard 645-2. The type designation of the individual products refers to the rail width in mm (e.g., MN 14 = rail width 14 mm). The design of the running tracks is based on the proprietary SCHNEEBERGER know-how. An interchangeability of rail and carriages exists within the MINIRAIL ranges.

MINISCALE is based on the proven miniature guideway MINIRAIL. Consequently, the guidance-technical specifications of MINISCALE also comply with MINIRAIL.

Linear bearing type RN

The RN linear bearing represents a consistent optimization of the R linear bearing. Thanks to the enlarged contact surface of the roller with the guideway, the performance capacitiy is significantly increased, with unchanged fitting dimensions.
The features of the RN include:
– approx. 3x higher load carrying capacity
– significantly reduced susceptibility to cage drift
– reduced danger of contamination due to narrower gap between individual guides

Micro frictionless tables type MINISLIDE

MINISLIDE is the latest generation of miniature slides for high-tech applications. Preloaded with zero play, a MINISLIDE is exceptionally smooth running. High rigidity and a low push force of less than 1 N will satisfy even the highest demands.

Process stability due to the elimination of cage creeping

No more cage creeping with a MINISLIDE. Sizes 4 and 5 contain a centring mechanism and sizes 7, 9, 12 and 15 incorporate a sophisticated SCHNEEBERGER cage control system. SCHNEEBERGER is thus the first company to put miniature slides onto the market that meet the demands of modern high-tech applications: maximum dynamics matched by a consistently high level of reliability.

The individual benefits you gain from the integral cage control system are as follows:
• Trouble-free operation which means more productive time
• High speeds and rates of acceleration allow faster motion and thus reduce cycle times
• No readjustment of the cage, not even when installed vertically
• The design and tolerances of the surrounding structure or differences in temperature do not result in cage creeping
• Long service life

SCHNEEBERGER builds custom-designed systems that are decisive for the manufacturing processes involved in semi-conductor production. With their microscopically small structures, these products have to be fully tested with high precision. The cost-effective production of even faster processors and even more compact memory chips than those we are familiar with today can only be achieved in this way.

Modern production processes for integrated circuits are at the limits of what is technically feasible. New processes are being continuously developed in order to further improve and to accelerate production processes. Frequently, the yield attained by new processes like these and the resultant semi-conductor chips is often very modest in the introductory phase. As the cost-effective utilisation of production plant capacity is the goal, quality control and a pro-active influence on processes are becoming increasingly important on the basis of results.

As a manufacturer of quality-control systems, SCHNEEBERGER plays an important role in the semi-conductor industry. Demands on the resolution and precision of measuring and imageprocessing systems are on the increase together with the gradual miniaturisation of semi-conductor structures.

Owing to their central function in the manufacturing process, these positioning systems permit the industrial production of semi-conductor structures and guarantee the cost-effectiveness of production lines costing billions.

Large-format positioning systems like those manufactured by SCHNEEBERGER for the flat panel display industry or the printed circuit board industry, can only be made as precisely and as robustly as our customers require thanks to our many years of expertise in these fields. The contrast between the mechanical size of a system and the microscopically small units of control structures is the greatest challenge in the engineering of such systems. The end products in large format manufacturing systems are often inspected even before delivery and assembly. Visual inspection using image-recording systems between the individual manufacturing stages and at the end of production is an important part of quality control for the manufacturers.

An electrical test at the end of production is usually accompanied by costs and requires the full range of CAD data as well as an automatic testing machine that contacts and tests all signal paths.

Optical tests are comparatively faster and more economical and can be carried out with a very high degree of precision thanks to SCHNEEBERGER systems. This gives the manufacturers of large-format products a relevant economic advantage.

The automatic optical inspection of flat panel displays or printed circuit boards has become standard in the industry in recent years. Thanks to its high-end positioning system, SCHNEEBERGER puts the manufacturers of this inspection equipment at the leading edge of technology.

Our positioning systems meet the highest demands both on camera systems as well as on scanner systems.
