TELESCOPIC STEEL COVERS

UNMATCHED WAY COVER EXPERIENCE

TOUGH, DURABLE PROTECTION OF SLIDEWAYS AND PRECISION MACHINE COMPONENTS

Chips, coolant, and other hazards are constantly trying to wreak havoc on your CNC machines, which is why Hennig helps your machines shield up with high-quality telescopic covers.

Quite frankly, we’ve seen it all and can design the exact way cover you need, whether you have state-of-the-art equipment, high-speed machines, or unique situations.

TELESCOPIC STEEL COVER FEATURES

Steel and Stainless Steel | Commercial-quality steel is used to withstand the abuses of the machine shop environment. Standard sheet thicknesses range from 1.5 mm (16 gauge) to 3 mm (11 gauge). Other gauges are available depending on the application.

Guides | Brass or non-metallic guides can be used on the covers. Small and medium size covers can be supported with non-metallic, low-friction guide shoes.

Interlocking Design | Wrap-around construction ensures precise location of individual cover sections and automatically provides the necessary initial preload for the flexible wipers.

Wiper Systems | High endurance, insertable polyurethane wipers keep the cover clean and seal out chips, dust and coolants. Abrasion- and coolant-resistant materials help ensure a longer life.

Support Rollers | To ensure smooth, accurate operation, large covers can be provided with rollers. Ball bearing, needle bearing and many other roller options are also available.

TELESCOPIC STEEL COVER OPTIONS

High Speed Module | Perfect guidance for high-speed covers up to 200 m/min (660 ft/min) and accelerations up to 2g over the entire traverse path. Ideal for linear motor machines.

Damping Elements (bumpers) | Bumpers are used based on machine speeds.

Wedge Dampener (ME Module) | Used to soften impact on the boxes.

Lifting Lugs | For ease of installation, lifting lugs can be provided.

Way Extension Brackets | Extend from the machine ways to provide support for the cover while it is in a compressed position.

Inspection Openings | For quick, easy inspections, hinged or Plexiglas® panes may be specified.

TELESCOPIC STEEL COVER SHAPES & DESIGNS

For any questions regarding the shapes and designs we offer for telescopic steel covers, please contact one of our specialists.

FLAT (AA)

The flat, u-shaped design represents the best economical solution for the protection of slideways.

PEAK OR ROOF (BB)

The roof-shaped design deflects coolant and swarf and provides higher rigidity and perfect guidance of the boxes.

SLANTED (CC)

The slope of this design ensures the diversion of coolant and swarf in one direction.

HIP ROOF OR FLATENED (DD)

The flat-roof form is used for broad covers to provide maximum rigidity of the box surfaces.

FLAT SLOPE OR DESK-SHAPED (EE)

This design improves the draining of coolant and swarf and the folded edge increases the boxes rigidity.

CROSS BEAM

Covers shapes AA, BB, CC, DD, and EE can designed for cross-beam applications.

VERTICAL OR LOUVER

In this type of cover, the individual plates slide in separate guide rails. Since these types of covers do not require slideways, they are particularly suited for the protection of column recesses.

DUAL OR DOUBLE AXIS

Dual-Axis covers are typically moving behind the tables and under the spindle when space is limited. This design is limited to 3 boxes unless guide rails are used, and must be flat.

CUSTOM COVERS

Different requirements and environmental conditions, complicated slideway forms, and less than ideal spacial conditions of special machines demand close cooperation between our design engineers and the machine tool manufacturers.

COUPLED

By coupling a telescopic steel cover, a longer travel can be obtained. The box height above the ways, based on the same travel, is less with coupled telescopic steel covers than with one individual cover. The compressed length however is longer.

WATER-TIGHT

Our standard TSC designs are splash proof and suited for high traversing speeds. For high coolant applications, we offer water-tight covers using gutters to divert coolant.

SERVICE & REPAIR FOR YOUR WAY COVER

Telescopic steel covers are only useful if they are fully functional at all times, ensuring minimized downtime. Hennig offers professional service and repair for all way covers (Hennig & non-Hennig brands) with a worldwide network of facilities.

FREQUENTLY ASKED QUESTIONS

Telescopic steel covers (TSC) are the industry recognized method of protecting guideways and other precision parts of machines from the ingress of chips and sharp-edged waste.

Steel covers are a heavy-duty solution which can protect in the harshest of environments and can also protect against tool or workpiece drops and, in the largest cases, when manufactured robustly enough can even be walked on. They help to increase the service life of equipment and are an essential part of machine tools.

We offer a wide range of services related to telescopic covers—for both Hennig covers and covers from other manufacturers. We repair, service, and replace components of your covers.
