High-speed grinding with QUICKPOINT combines JUNKER precision with maximum flexibility. QUICKPOINT ma-chines can be used for a wide range of applications, and at the same time boast impressive productivity. The result: versatility and excellent workpiece quality.
Grinding with QUICKPOINT is OD high-speed grinding using single-point contact in the finish grinding area. QUICKPOINT works with an extremely low-wear CBN or diamond wheel just a few millimeters wide. By creating a relief angle, the contact zone between wheel and workpiece is reduced from a contact line to a contact point.
QUICKPOINT standard operations are shoulders, tapers, chamfers and plunge cuts. In addition, flute and thread grinding, as well as polygonal and surface grinding can also be integrated.
This system has been applied to the wheelhead, workhead and tailstock and shortens the machine’s tooling times.
With a wide selection of wheelhead combinations, the QUICKPOINT line offers OD grinding solutions for practically any application: from the compact QUICKPOINT 1000 for smaller parts, to the QUICKPOINT 5000 for medium-sized parts, all the way to the QUICKPOINT 6 for large workpieces. Wherever you use a QUICKPOINT, it guarantees a low-cost manufacturing process.
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.
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.
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.
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.
All JUCENTER versions can also be equipped with carbon grinding wheels. Technical advantages are higher cushioning and reduced weight. There is also an important economic aspect: higher productivity thanks to longer tool life and dressing cycles, as well as significantly fewer wheel changes.
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.
The Filtration 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.
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.
