Machine spindles - Import export

Decades of experience in development and top precision in manufacturing GMN machine spindles with certification under national and international quality standards secures permanent outstanding characteristics in regards to bearings, Speed suitability and machining. The options for standardized series offer the best spindle solutions for nearly all applications. A variety of successfully-implemented GMN special designs confirms that we can develop outstanding, high-performance products to assist our customers in extraordinary construction projects.

GMN high-speed spindles of the HS, HSX, HV-X and UHS series are irreplaceable for grinding work. Whether you must work with holes or frames, with these spindles you always make the right choice. The HV-X and HV-P series are optionally available with a rotational angle sensor, and therefore outstandingly suitable for 4Q operation. The types in the HV-P, HSP and HSP..g series are equipped with an HSK-C holder and furthermore suited for milling and drilling applications.

The current series TSA, TSI, TSP, TSAV,of the external-driven GMN tool spindles follow the first grinding spindles made by GMN in the 1930s. Then and today, we provide simple, but robust and functional spindles that reliably fulfill their tasks. Depending upon the customer’s tool selection, spindles are available with various tool holders.

GMN high-speed spindles of the HC, HCS, UHS, HCT series are an essential component of highly-effective machining of various materials. Whether aluminum, steel or titanium, these spindles are optimally designed for all machining tasks which require performance, torque and speed. Using an oil-air or grease permanent lubrication, the spindle bearings operate in a secure fashion.

Our extensive service network ensures that we can offer expert advice as well as long term maintenance and quick repairs. If the spindle function is compromised, GMN service technicians are on-site quickly to ensure that our customers maintain maximum productivity. Equipped with the latest technology, GMN repair service guarantees a detailed cause analysis and professional service – worldwide.

Lubrication of open pinion gears which are highly subject to wearing due to corrosion and continuous soiling, e.g. on construction machines, spindle presses, crushers, mills, windlasses, rubbish disposal devices, ship´s lifting jaws or water structures Wire cables subject to outdoor weathering, e.g. on crane systems, lifts and aerial tramways, ship´s and offshore equipment for diverse types of sealing lubrication, including of coarse chains and chain transporters Advantages and benefits Highly effective due to outstanding wetting and lubricating properties Decreased friction and wear, and therefore reduction of necessary repair times Economical due to thrifty consumption as a result of small application quantities and time-saving use due to advantageous spray form Dry, elastic film with high adhesive strength prevents adhesion of dust and dirt Waterproof and has good corrosion protection properties

The SGS (Spindle Growth System) 4701 displacement measuring system is developed for high speed milling machine applications. Due to high machining speeds and the heat generated, the linear thermal expansion of the precision machine tool spindle needs to be compensated for in order to keep the tool in a defined position at all times. The SGS sensor measures the expansion of the spindle caused by thermal and centrifugal force. The measurement takes places typically on the labyrinth-ring. As well as the linear expansion, the temperature of the sensor is detected and output.These measurement values are fed into the CNC machine tool as correction values, compensating for any positioning errors.

Lubrication of roller and plain bearings as well as of threaded spindles, gearwheels, worms and similar components Lubrication of spindle bearings in machine tools Advantages and benefits Allows high machine service lives due to low-wear operation and low lubrication frequencies Outstanding resistance in a wide temperature range, at high stresses and surface slide speeds as well as at vibrations Resistant to cold and hot water Excellent wear protection For highest effectiveness carefully clean the lubrication point, for example with OKS 2610/OKS 2611 universal cleaner. Before filling a bearing for first time, remove anti-corrosion agent. Fill the bearing such that all functional surfaces are certain of being greased. Fill normal bearings up to about 1/3 of the free space inside the bearing, high-speed bearings (DN value above 400,000) up to about 1/4. Low-speed bearings (DN value below 50,000) and their housings should be filled completely.

Metzner has developed the mandrel cutting machines of the SR series for cutting off sealing rings from injection-moulded or extruded tubes with different diameters. These machines are characterised by their unique processing method and high cutting quality. First, pre-extended "rubber tubes" are clamped onto mandrels. Due to the special design of the mandrels, the mandrel can be set up and removed quickly and without special previous knowledge. The mandrels are then automatically clamped in the machine between rotating spindles and production is started. A knife carriage travels along the tubes and cuts the flat sealing rings to the desired length with either push-fit or circular knives, depending on the requirements. This cutting method is particularly impressive with its high cutting quality in combination with a high output.

Profiles and sealing systems often require ventilation holes or mounting holes. Drilling equipment from Metzner carries out these tasks. We provide the following solutions adapted to your specific requirements: - In-line as an eccentric drilling station for regular drilling at equal distances - In-line as travelling drilling station for drilling at the same or variable distance - In-line as "drilling beam", which carries out all drillings for an entire sealing profile with variable distances in one operation - Off-line for drilling in combination with final trimming The machine is equipped with drilling spindles with very high speeds of up to 60,000 revolutions per minute. An exact drill hole is thus achieved in a short cycle time. The geometry of the drills ensures that the waste falls to the outside.
