Geometrically symmetrical structure of the X-Y-Z coordinate carriage, ensuring uniform thermal expansion
Thermal stability at Tool Centre Point (TCP) in the X-Y plane without compensation
Ultra-high rigidity and vibration dampening qualities due to nodular cast iron framework resulting in superior tool performance
Optimised contour accuracy at high path speeds
Extremely high parallel traversing accuracy due to double drives in the X and Y axes
Base Frame
Using a GS 1400 as an example
The "Heavy Weight" for Milling and Turning
Extremely rigid, integral base frame made of one piece. Fully statically stressed frame components are made of grey cast iron. All dynamically stressed frame elements are made of nodular cast iron.

TRAVEL SYSTEM CARRIAGE
Design Characteristics
Carriage designed as a Box-in-Box system with symmetrical and structured mono block cross slide, as well as integrated Z-Axis slide and motor spindle.
Multiple guide-ways in all linear axes.
Single- and double-ball screws with Servo drives for the linear axes.
NC SWIVEL AND ROTARY TABLE (SDK)
Gear or torque drive technology according to the application-specific design
Gear drive in swivel and rotary axes for economical 5-Axis machining.
OR
Direct torque drives, on rotational axes for smooth and highly dynamic oscillating machining tasks.

GANTRY-CONSTRUCTIONS
Conventional and modified Gantry Design
4-Fold internal linear guides.
Deviation (deflection) is reduced by a factor of 2.3, and thus rigidity is 2.3 times higher than "on top-mounted" systems.
Less positional error at the tool centre point (TCP).
Significantly increased cutting tool life.

TESTIMONIALS
I would like to say thank you for your assistance so far. We have only drilled 4 x 0.80mm holes 50d deep but the fact they worked the first time was appreciated by everyone.
Senior Manufacturing Engineer
Moto Sport
We use OSG mainly but when we have a specific job that needs doing, we come to Rainford Precision because they are and do the Crème De La Crème of Products and services.
Works Manager
Precision Engineering
The End Mill was an ideal choice due to the unusual shape and the need to have a small radius. They turned out great, and the surface finish is really good.
External Works Manager
Precision Engineering
I would like to say thank you for the help you have given our project over the last few years. Your advice on the correct cutters plus the right speeds and feeds has not only helped with accuracy but brought the cycle times down so we can meet our project deadlines.
