TITAN - Centerless grinding machines

Throughfeed grinding in finishing quality

The TITAN 500 produces workpieces to a superb standard of finishing quality using the throughfeed grinding technique. To allow this high standard of quality to be achieved, the TITAN features a wide range of machine attachments such as wheelhead, regulating wheelhead, work blade and infeed/outfeed which are aligned and calibrated to an extreme degree of precision. Another key factor in the achievement of final quality workpieces is a high degree of machine rigidity using a vibration-damping, highly torsion-resistant cast mineral machine base designed specifically for CBN grinding.

Highlights

Rough and finish grinding to final product quality take place in a single grinding operation (no intermediate handling)
High level of concentricity due to market-leading machine rigidity and the use of CBN grinding wheels
High output through short cycle times due to centerless throughfeed grinding
High stock removal rate due to patented automatic adjustment of the work blade

Grinding process descriptions
Using the throughfeed process with a wide CBN grinding wheel, the workpieces pass in seamless sequence through the machine, provided all workpieces have only a single diameter requiring a uniform grinding operation. The axial force of the regulating wheel, which is generally inclined at an angle of 1.5 – 3.5°, „pulls“ the flow of workpieces through the wheels towards the end of the grinding cell. Used in conjunction with an automated loading and unloading system, the workpieces pass through the machine without interruption.

Equipment and Options

CONTROL SYSTEM: The Erwin Junker Operator Panel was specifically developed to control grinding machines. All machine components are controlled using the operator panel – irrespective of the series and the used control system. The identical structure, intuitive menu guidance and visualization of the workpiece geometry make for extreme user convenience and flexibility in operation. Programming takes place directly using the operator panel or an external programming tool.
DRESSING UNIT: Grinding wheel dressing is CNC controlled. A driven diamond dressing wheel or a workpiece-dependent diamond profile roller can be used. Dressing takes place manually or using an automatic dressing program with grinding wheel compensation.
MACHINE BED: The machine bed made of mineral cast provides impressive damping behavior and torsional rigidity. The temperature stability allows fluctuations in the ambient temperature to be compensated with a minimum of effort, ensuring a high level of dimensional stability throughout the whole day.
ABRASIVE: Depending on the application, the abrasive CBN or diamond is used. The basic bodies of the grinding wheels comprise steel or carbon. In conjunction with CBN, it can make sense to use a carbon base body: It is light, has vibration-damping properties and remains dimensionally stable even at high speeds.
LOADING SYSTEMS: JUNKER offers both internal and external loading systems for all its machine series, depending on customer and workpiece requirements. The loading systems can be combined with different infeed and discharge systems such as conveyor belts or custom tailored systems.
MEARSUREMENT SYSTEMS: The measurement systems are also individually adjusted to the various workpieces and customer specifications. The measurement processes entail evaluating the recorded measured values and utilizing them for measurement correction in line with the prepared measurement strategy. A grinding wheel measuring system to determine the diameter, axial position and width of the grinding wheel completes the wide range of systems on offer.
FIRE PROTECTION AND LTA AIR FILTERS: In case of an fire, the machine interior is automatically hermetically sealed, suffocating a fire before it has a chance to spread. If required, extinguishers (CO² or water mist systems) and exhaust air purification systems can be additionally installed. A competent partner for fire protection and filtration solution solutions is LTA Lufttechnik GmbH, which also belongs to the JUNKER Group and which researches, develops and produces filtration systems for industrial air purification.
