Thundermac Series – 4-Side Moulder

Thundermac Series – 4-Side Moulder

The leadermac thundermac series 4-side planer / moulder was developed with the aim of improving productivity and surface finish. The thundermac series features high feed speed of up to 80 m/min (265 rpm) as standard and optinal extra high feed speed of up to 200 m/min (656 fpm). is available. Each spindle is driven by an individual 15 and 22 kW / 20 and 30 HP motor and optional to 45 kW (60 HP), allowing for heavy cutting. A wide range of spindle configurations from 2 to 11 spindles provide flexible choice to meet specific moulding requirement. Maximum stability during high speed is attainable thanks to the rugged construction throughout.

Equipped with a user-friendly programmable controller, the desired values for width and thickness can be conveniently pre-set and are displayed on the LED readout. (Optional)

Built for super-high production requirements, the thundermac series of 4-sided planer / moulder can bring your production speed to a new level

The thundermac series is designed for high-capacity, highly quality operations for large and small batch production runs. The heavy-duty spindles are dynamically balanced and run in premium housing bearings, for superior workpiece finish quality

The thundermac provides perfect surface quality, eliminating the need for sanding on planed and profiled surfaces

4 Good Reasons to Buy Leadermac Moulders

  1. Output quality
  2. Quick efficient setup and operation with the latest in technology
  3. Dependability
  4. Service

Every 4-side moulder from Leadermac is built with Leadermac’s traditional quality excelence, maximum dependability of performace year after year combined with comprehensive technological service.

Fully Automatic Feeding System (Optional)

When the system detects the workpiece on the infeed chains, the hydraulic feed system will pneumatically lower and activate the top roller to feed the workpiece into the machine. This provides constant and stable feed, reducing labor requirement and decreasing cycle time.

For All Your Woodworking Applications

230 mm LMC-223T (2-spindle) to LMC-1123T (10-spindle) or 305 mm LMC-230T (2-spindle) to LMC-1130T (10-spindle)

Outstanding Features:

  • All moulders with CE certification if desired.

  • Programmable controller provides convenient thickness and width of cut settings.
  • Adjustment of each spindle can be easily performed using the front of the machine adjustment. Exclusive, separate adjustment of the vertical spindles and the support tables allows the tables to be positioned extremely close to the cutterheads for added cutting stability.
  • The full safety enclosure serves as a chip guard and helps to reduce noise and is equipped with strobe free lighting.
  • Each spindle is driven by an individual motor for powerful moulding and easy control
  • Multiple pneumatic pressure of the feed rolls can be easily set to provide an outstanding feeding effect.
  • Table surface, guidesm chip breaker shoes and pressure plates are hard-chrome plated for maximum wear resistance.
  • All manually adjusted and turning parts are housed in dry grease lubricated bearings for oil-free lubrication
  • Automatic lubricator is provided to supply oil to the feed tables
  • One-piece, extra heavy machine frame is specially heat treated for maximum stability and rigidity by standrd configuration
  • The powered top and bottom full width rolls provide stable and smooth workpiece outfeed even for especially thin or smooth materials. The rolls remain perfectly parallel even after long-term use.
  • Mechanical digital readouts for all head axis and pressure elements and chip breaker shoes and pressure plates of the top spindles
  • Sectional chip breaker assembly in front of top spindles
  • Finest alloy steel spindles and housings with 2 sets of ultra precision duplex bearings in each spindle. All are permanently grease lubricated.
  • All horizontal spindles outfitted with quick lock hydro-lock outboard bearings and cutterhead supports
  • Built in straight and profile jointers provide accurate operation with high quality finish
  • The full safety enclosure is heavy gauge steel and serves as chip guard and helps reduce noise. (optional)

Automatic Lubricator

The machine comes equipped with an automatic lubricator, which automatically delivers lubrication oil to the feed table, ensuring smooth feed at all times.

Pneumatic safety lock device

The lock device is deigned with two air cylinders to tighten the hydro-bearings housing to achieve dependable locking function. The top air clinder actuates to tighten the hydro-bearing housing in axial direction, while the bottom air cylinder is used for tightening in radial direction.

Feed System

The infeed rolls work in conjuction with a limit switch (anti double-up gate) to stop the machine feed if the workpiece is too thick or there is double up.

Designes for Paramount Stability

Powerfull, heavy-duty pneumatic side and pressure shoes for the left spindle provide extremely stable pressure for high-speed operations. A pneumatic top pressure roller system in front of the right vertical spindle ensures constant stock feed.

Powered Infeed Roller

The smooth initial feeding of the stock is achieved by means of the independently powered top and bottom infeed rolls.

Convenient Spindle Adjustment

Adjustment of all spindles is easily done from the front. The adjustment points are all at the same height, for more convenient and faster adjustment.

Heavy Duty Gearbox and Motor

The feed rollers are driven through a combination of universal shafts and gearboxes, ensuring no loss of power tranmission. A smooth feeding effect is assured. Heavy duty gearboxes have no backlash and provides powerful and accurate feeding performance.

Clamping System

Utilizing housing bearings, the reliable hydro-clamping system ensures consistent quality across the entire workpiece. The unit performs admirably even during high-speed continuous operation. The spindle can be adjusted axially even if the housing bearings are locked.

Controller

The speed is VFD inverter controlled, and all electrical components meet CE, UL & CSA standards
