Flat grinding machine, Knuth HFS 2550 F Advance

Flat grinding machine, Knuth HFS 2550 F Advance

Manufacturer: Knuth, Germany

Knuth HFS F Advance is a flat grinding machine with the latest technology and factory tested and proven, which has earned its good name in many companies for many years. Although flat grinding is a widespread machining process, these machines are attractive because they have a wide range of standard accessories. New control functions using Siemens technologies have been implemented. This machine is an especially good choice for people for whom the manual machine is too small and the CNC machine is too big.

• Magnetic workbench and built-in demagnetization area nearby.
• The vertical axis has a ball screw and servo-motors that ensure a high level of accuracy.
• Easy programming of the automatic mode, thanks to the Siemens PLC controller and its touch screen.
• A wide set of standard equipment.

More detailed description:

• The frame of the machine, which is made of cast iron, provides a particularly strong and torsion-resistant construction. This guaranteed stability and precise guide rails ensure the high quality of product processing.
• All guide rails are reliably lubricated by centralized lubrication systems.
• The workplace is protected by an easily accessible cover.
• A powerful cooling pump combined with an extraction pump to effectively remove sanding dust and various fumes that arise during sanding.
• All the necessary parameters, due to careful grinding, shaft feeding - are entered and adjusted using the Siemens controller.
• The high-quality loaded ball screw and powerful servo-motors ensure extremely accurate and reliable positioning of the processed products on the Y axis.
• The machine uses an electronic wheel that can be turned by hand to change the parameters of the task at hand, or to manually move the grinding shaft.
• If the machine is set to automatic mode, then the machine performs the product roughing and finishing processes, repeat operations and returns to the starting point automatically.

Grinding shaft:

• Large grinding shaft, dynamically balanced, fully enclosed and lubricated.
• Pre-loaded bearings ensure maximum grinding efficiency and a high level of reliability, even after many hours of production.

Hydraulics:

• Extremely quiet operation and minimal heat generation, even when working at high speeds.
• Hydraulically controlled linear movement of the work table, with a wide range of applicability, high accuracy and the ability to gently change the position of the product.
• External hydraulic unit with oil cooler that ensures precise temperature stability.

Magnetic mounting plate:

• A large magnetic clamping plate ensures reliable and long-lasting operation of the mechanism, which does not require any rotary action.
• The control panel is integrated into the electronic system for ease of use. Fast and convenient clamping of parts is possible, which maximizes production efficiency.
