Universal cylindrical grinding machine

The Kellenberger Varia universal cylindrical grinding machine offers a large work space, long machine table, and distance between centers of up to 63" (1,600mm).

Hydrostatic guideways provide damping, stick-slip-free operation, high rigidity, and a constant machine temperature, improving surface quality and process and operation reliability without friction loss and wear. Direct drives on the rotary axes offer high positioning speeds and accuracy. Drives move the longitudinal and cross slides at speeds of up to 787ipm (20m/min) at an axis resolution of 10nm. The hydrostatic B-axis is equipped with a direct drive, allowing the revolving wheelhead to rotate 3x faster and with position precision of <1 arc second.

The Varia is available with distances between centers of 39.4" or 63" (1,000mm or 1,600mm), and center heights of 7.8", 9.9", or 11.8" (200mm/250mm/300mm). Travel on the X- and Z-axis is extended. The task defines the position of the wheelhead within the machine, which ensures optimum distance and dressing conditions. More than 30 wheelhead variations with external and internal grinding spindles permit the right application-specific grinding configuration.

Heidenhain GRINDplus640 controls provide user-guided ISO programming with selective help images and collision monitoring. The controls allow faster working speeds and high precision. Axis control in the nano range offers high profiling and track accuracy for contour grinding. Optionally, the Varia can be equipped with the Fanuc 31i control. Remote maintenance with integrated IT security connects to the customer network via VPN tunnel or mobile communication.

Multisensor dimensional measurement system

The large measurement volume SmartScope Quest 800 multisensor dimensional measurement system offers a 790mm x 815mm x 250mm X-Y-Z measurement volume and an available 300mm or 400mm extended Z-axis to measure large parts or large arrays of smaller fixtured parts. For measurement stability, the Quest 800 optics/sensor head is mounted on a granite bridge over the worktable and moves only in the X- and Z-axis, while the worktable moves underneath in the Y-axis. A 10:1 TeleStar telecentric zoom lens offers accurate video metrology. The unit is multisensor-capable with available touch trigger probe, SP25 continuous-contact scanning probe with PH10 motorized probe head, on-axis TeleStar Plus interferometric TTL laser or off-axis DRS laser, and micro-probes to measure fragile parts or extremely small part features.

The system is available with QVI’s Zone3 CAD-based 3D metrology software with a kinematic model that simulates the machine, part, fixtures, and measuring sensor in real time. Integrated geometric dimensioning and tolerancing functionality and visual validation of measurement intent speed the measurement process. Zone3 supports simultaneous use of multiple sensors, including multiple lasers, making appropriate tools available for complex measurement tasks.

Cutting tools for continuous tool path machining

The Pow ·R ·Path IP series of cutting tools are designed to maximize high-efficiency machining (HEM) methods. Taking advantage of continuous tool paths to get maximum performance out of every tool, the Pow ·R ·Path IPT7 series and Pow ·R ·Path IPC series feature 7-flute configurations. IP series tools are made with a stronger, larger-diameter core for straighter walls in deep cuts and superior strength for longer continuous cutting at HEM’s high feed rates. Pow ·R ·Path IPC7 and IPC9 series (7- or 9-flute styles) add the special chip management system (CMS) for reliable chip evacuation even in tough alloys.
