Used Weinig Unimat 23 E woodworking machines

WEINIG Unimat 23 E – Four-sided planer and moulder

The WEINIG Unimat 23 E is a four-sided planer and moulder for through-feed processing of solid wood. It combines face and edge straightening with planing and profiling. Typical applications include window and door profiles, furniture components, mouldings and components for interior fitting.

The standard version handles working widths of 20–230 mm and working heights of 8–120 mm. Four to seven spindles provide different machining sequences. The feed speed is infinitely adjustable from 5 to 24 m/min.

Machining and Machine Configuration

A 2 m straightening table supports workpiece feeding. The straightening table and fence have an adjustment range of 10 mm. The feed rollers are driven by cardan shafts and pneumatically loaded. Driven rollers in the outfeed table assist workpiece transport.

The top spindle and feed assembly have motorised height adjustment. Mechanical digital indicators assist setup, and workpiece dimensions are displayed as absolute values. The vertical spindles have an axial adjustment range of 80 mm and the horizontal spindles 45 mm. A full sound-insulating safety enclosure surrounds the machining area.

Depending on the spindle arrangement, machine length is approximately 3.7–5.0 m, width approximately 1.8–1.9 m and height approximately 1.6–1.8 m. Weight is approximately 3,000–4,100 kg. These figures refer to the eight illustrated configurations and are not uniform dimensions for every machine.

Special equipment and model variants

Universal spindle: Machining from above, below, right, left or at an angle, for example for grooving, back profiling or ripping. The cutting circle is 100–200 mm.
Left mobile spindle: Electronic measurement of varying rough timber widths and automatic adjustment of the spindle position. Stock removal is programmable, and up to 40 preset dimensions can be stored.
WEINIG ATS: Storage of up to 98 workpiece dimensions and automatic positioning of the left and top spindles, taking the tool radius into account.
WEINIG CAS-LogoPac: Computer-assisted setup system for up to 9,999 profiles. It manages profile and tool dimensions and displays calculated settings at the spindles. Adjustment is carried out using handwheels.
Short-length processing: Reduced roller spacing and a short-length package for workpieces from 320 mm long are available as extras. A groove-guiding system assists the processing of short, curved workpieces and those with untrimmed ends.
Extended power and working ranges: Options include a feed speed of 6–36 m/min, more powerful spindle motors up to 15 kW, a feed drive up to 8.6 kW, and versions with a 260 mm working width or a 160 mm working height.
Further equipment: A glazing bead saw, a shortened 1.2 m infeed table, a 2.5 m straightening table, feeding magazines and additional workpiece handling equipment complement the range.

Application and classification

The Unimat 23 E is suitable for four-sided planing and producing profiled solid wood components in small and larger batches. Machining capabilities depend on the spindle arrangement, tooling and optional equipment actually fitted. Standard specifications and optional extended working ranges must therefore be considered separately.
