Hoffmann MS 35-SF-NC Double Mitre Saw

Description:

The Hoffmann MS40SF-NC double miter saw is equipped with two sawing and routing stations, mounted at a fixed 90 degree angle to each other. This assures perfect 45 degree miter cuts on two parts simultaneously.
Each station consists of a saw blade to cut the material, and a routing head below to rout one, two or three dovetail keyways per miter.

The machine features automatic adjustment of cutting length and automatic adjustment of keyway locations and keyway routing heights. Dual stepper motors are used to adjust keyway locations and keyway routing heights are controlled via electro-pneumatic sensors.

A large touch screen and industrial PLC unit are installed to control the various axes.
Displayed on the screen are, besides the actual cutting length, also the keyway locations and routing heights.
In addition, the system can be configured to display an image of the moulding being processed to aid in the operator's visual verification. (.JPEG Images to be supplied by client).

The hand-held scanner option allows the operator to scan a bar or QR code on the worksheet to quickly and accurately adjust the cutting length, routing locations and routing heights of the machine.
The QR code also includes the total quantity of frames to be made and the profile number which the software uses to display an image of the moulding for visual verification.

The ELA-2 positioning system was designed and is manufactured by Hoffmann in Germany.
The System is integrated into the operation of the MS40SF-NC in that the stop automatically moves out of the way to allow the machine's tables to open for the routing process. Once the routing sequence is completed and the tables are in their home (closed) position again, the stop tracks back to the proper position.
The saw's safety circuit is connected to the stop and vice-versa assuring utmost operator safety.
The positioning system is installed on the right hand side to function as a precise length stop system.

Applications:

Solid wood, MDF as well as plastics and composite profiles can be cut and routed for Hoffmann Dovetail Keys with speed and accuracy.

Non-ferrous metal, e.g. aluminum profiles, can be cut with appropriate saw blades (with dovetail routing sequence disabled by operator).

Typical applications include window and door components made of wood, PVC or aluminum, mitered cabinet doors, applied moulding frames for wall paneling and doors, decorative trim and casing profiles, architectural millwork, shutter frames, store fixtures, shelves, wood components for the furniture industry, plastics and aluminum parts for the RV industry, picture and mirror frames, etc.

Machining sequence:

• Operator enters information for cutting length and keyway locations on touchscreen manually or via QR code scanner (or recalls previously stored parameters), then places work-piece on machine table.
• Operator activates two-hand safety controls – pneumatic clamps secure material on table.
• Saw blades cut through material and retract up to their home position.
  Triangular waste piece is secured during cutting operation and ejected toward front of machine into scrap chute.
• Router motors move up and rout keyways to pre-set lengths, then retract below tables.
• Pneumatic clamps release the material and operator removes finished part.
