Automatic Vertical Mitre Saw Cutting Process

The system is well suited for production double mitre cutting for picture and photo frames as well as any other moulding or trim board assembled by way of 45 degree mitre cutting.

Sophisticated, but simple and practical, the system is made three major components, Vertical or Horizontal Material Feeder, Cutting Station, with two saw blades fixed at a 45 degree angle, and an Unloading Belt with Kicker allowing cut pieces to be pushed aside to avoid any damage.

Based on the customer’s moulding profile design, this proposal does not include pricing for any special part fixture tooling required for use with either the Vertical or Horizontal Material Feeders.  If needed, this additional tooling will be quoted separately.

A Material Gripper System (Primary) is used to provide moulding part movement into the Saw Cutting Station, an optional Material Gripper System (Advanced) is also available, and is used in conjunction with the primary gripper for minimizing moulding scrap and to increase overall material yield rate.

The cutting system is equipped with a Speed Feed Servo System for production rates up to 1,900 cut pieces per hour.

A Vertical and Horizontal Clamping System within the cutting station firmly holes the moulding during the cutting process giving higher accuracy and a superior cut edge quality.

The system Touch Screen Controller is equipped with an easy user interface and displayed in the desired language.

Production Capacity

The TA-350 has production output range up to 1.500 pieces. Actual customer production rate is dependent on a number of variables, length of moulding at in-feed stage, length of cut, moulding cross section and type of moulding.

System Controller - Software Features

A password protected software platform with a friendly navigational graphic menu guides the operator through the various steps of programming.

During program writing, the operator has to choose the frame type and establish needed dimensions choosing to refer the size to either the outer or the inner frame. If the choice is for the inner frame, the operator has to set the width of the moulding and the machine will automatically calculate the cutting length of each frame piece.

Setting the quantity of picture frames, the machine will automatically cut the number of needed pieces. 

Continued Mode: execute all pieces of one length first and then automatically execute the pieces of second length, also a third length if it is needed.

Alternate Cutting: execute two long and two short lengths each cut cycle to complete (1) one picture frame assembly

Sequence Cutting: any particular sequence of lengths decided by the operator

Production Cutting List: possibility to store up to 30 lines, with length and quantity of pieces

Program Storing Capacity: unlimited, possibility to store/write a new program when the machine is working
