Cylindrical grinding machine CNC of production.
Series GL particularly adapted to the mass and series productions, is made up of allied machines of great robustness to a very high degree of accuracy.
Our range GL very largely used by the aeronautics and automobile manufacturers.
The GL are declined in many versions, in particular with divings right or oblique and grinding stones CBN or conventional.
The lubrication of the ball slides and screws is carried out in closed circuit, thus getting a powerful and economic greasing.
They offer a great flexibility and are configurable made-to-order according to the requests of our customers.
Numerical control GC50 developed by our engineers proposes a very convivial interface HMI, with touchscreen in color and a multitude of preprogrammed cycles very easy to exploit.
The cycles of correction suggested are configured in conversational conversation mode, the procedures of change of grinding stone, of adjuster or locator are extremely simplified and detailed with the screen stage by stage to avoid any error.
Of series a car-calibrator TOYODA is proposed thus that a side locator.
The implementation and the changes of series are of a great simplicity, the access to the elements of catch of part and the tools such as the grinding stone and the adjuster are optimal for rapid interventions and without risk.
Finally the capacities suggested go 250 mm between-points up to 2500 mm, and 60 mm in diameter usinable to 300 Misters.

Cinetic Landis fully programmable CNC Plain and Angle Grinders are ideal for medium-to-high volume production cylindrical grinding. These grinders offer the flexibility to do skive grinding using a narrow wheel and traversing table, stitch grinding for plunging multiple diameters, or traverse grinding of straight diameters.
The Landis CNC Plain and Angle grinder is a cylindrical grinding machine designed for high production grinding of concentric or eccentric parts. This value-engineered grinder has been designed using Finite Element Analysis techniques to combine the superior output potential of a flexible grinding system with maximum cost effectiveness.
The Landis CNC Plain and Angle grinder is available in either straight or angle wheelhead models. The angle head model is especially cost-effective because the ability to use up to a 760mm diameter wheel significantly increases wheel life in angle grinding. The Landis CNC Plain is the ideal machine for grinding a wide range of parts including concentric power steering components, transmission-type parts, small camshafts and small crankshafts.
Available in 250 or 350mm grindable lengths

The Haro Sharkline is a 5-axis NC for both producing and grinding/sharpening complex tools. A very powerful software toolbox has been developed for exceeding the market demand in terms of managing tool complexity.
A patented gantry beam design allows all angular and cross positioning for the wheel without any restriction. With its 500 mm longitudinal and cross stroke, this product is designed for grinding or cutting from solid, for producing complex tools and tool tips with a single adjustment…
High speed spindles are adjustable step-less from 3’000 to 18'000 RPM and powered from 3,5 to 10 kW. The HARO grinding spindles with double output shaft are greased for life and water cooled. Their magnetic and dynamic balancing is so accurate that surface quality of Ra 0.03 µ can be reached. Their compact volume increases the possibilities of the grinder as well as its capabilities, makes settings easier and provides a better visibility.
The NC control is based on Siemens technology (SINUMERIK 840 Di)and will take advantage of our experience based grinding software.

Thread Grinding Machines GAS, GIS, GUS
Application Range
GAS
External and internal ball screw tracks for automotive steering systems, worms.
Drive worms.
GIS
Internal ball screw tracks for automotive steering systems.
GUS
External ball screw tracks for automotive steering systems,
internal ball screw tracks for automotive steering systems.
Note: The GUS version has exchangeable grinding units for external and internal threads.
Tooling Concept
Non-dressable CBN profile grinding wheels consisting of a hardened and precision ground steel base body with a single layer of CBN galvanically applied to the wheel form.
Note:
The key advantage of the KAPP tool concept using non-dressable CBN profile grinding wheels lies in the excellent wear resistance of the CBN layer, which makes it possible to grind a large number of workpieces at consistently high form accuracy without dressing the wheel. For high volume productions of ball screw type automotive steering system, this results in significant cost reduction as it minimizes the classifying process and, equally important, allows closer tolerances, which improves both the efficiency and rolling action of the components because of reduced backlash.

The LT3 Large Orbital Crankshaft Grinding Machine is the latest innovation from Cinetic Landis Ltd. Designed to grind large crankshafts, the LT3 gathers state-of-the-art technological developments, providing outstanding features.
The machine grinds the crankshaft main bearings on axis and orbitally grinds the crank pins without having to remove the shaft from the machine, so increasing the accuracy of the geometry of the shaft. In addition, the machine is capable of grinding crankshaft end diameters, faces or tapers.
The design of the machine includes new FEA methods to develop unique bed and foundation design. The existing 6400 CNC machine control system was enhanced to allow the simultaneous application of up to 40 servo axes. New methods of supporting and locating the crankshaft together with unique grinding processes allowed finished part roundness results of less than 0,002mm on a 300mm diameter main bearing or crank pin. Both soft and hardened steel cranks have been ground. Hardened steel cranks include sidewalls & fillet radii.

The highly productive Landis LT2 Twin Wheelhead crankshaft grinder provides the flexibility needed in today’s global automotive manufacturing industry by allowing multiple operations to be combined in a single grinder, thereby minimizing the number of machines and reducing capital expenditure.
The LT2 grinder’s two independently programmable wheelheads can be tooled with cBN grinding wheels to perform several different processing methods:
* Finish grind two main journal diameters simultaneously
* Finish grind two crankpin journal diameters simultaneously
* Finish grind main and crankpin journal diameters in a combined operation
+ Finish grind other concentric diameters and thrustwalls by various sequencing of twin wheelheads
This capability allows tremendous flexibility in developing highly productive processes. In certain applications, it is possible to grind all of the concentric and non-concentric diameters on a crankshaft with only one fixturing using different width wheels on the separate wheelheads as necessary.
Key Features Include:
* Hydrostatic ways on the X-axes for high stiffness and improved contour accuracy
* Wear-free permanent magnet linear motor wheelfeed drive system for faster workspeeds and improved part quality
* Hydrostatic wheel spindle that improves finishes and provides consistent maintenance-free accuracy
* Motorized headstock drive Motorized spindle dresser for precision wheel truing and wheel profiling capability
* Available in 680 and 1400mm grindable lengths
