  • Page 2 MICROMAT PCB DRILLING SYSTEM INTRODUCTION Welcome to the Micromat World of Drilling. If you are an existing Micromat user you will already be aware of the advanced features and concepts of the Micromat control system. The Model 1575 takes those features a step further in usability. This screen based control system provides an unequalled clarity of comprehension and with direct CAD disk compatibility there should be no circuit boards that you cannot process.

  • Page 3: Routine Servicing

    ROUTINE SERVICING The only basic attention required by the Micromat is that it is kept clean and free from dust and grease. The swarf extraction unit should be emptied at least daily and the filter bags well shaken to avoid dust clogging and subsequent overheating and destruction of the motor. The motor brushes should be inspected monthly and replaced if required.

  • Page 4: Installation

    In some areas it may be necessary to use a power supply filter / regulator unit to prevent power line interference. Although the Micromat will operate under a wide variety of conditions it should not be subjected to extremes of temperature as this will obviously affect its accuracy.

    Please don't press any keys at this point. After a few moments, the Micromat Welcome screen will be shown and a number will countdown from 10 to 1 while the control system is loaded and configured.

  • Page 7: Menu Screen

    This is the central point of the control system and any of the three screens through which the system is controlled may be accessed from here. All the functions of the Micromat control system are accessed through either the Program, Run or Files screen, making the system simple to learn and easy to remember.

  • Page 18: Program Backup

    ..so just use floppy disks. The Micromat has another program backup system and its use is intended to solve the problems of power failures and other inadvertent shut downs which may cause loss of data.
  • Page 19 Arcs can be entered by just using the Down command to program three points around the arc. The cutter will trace an arc through all three points starting with the first point, moving through the second point and finishing at the third point. Micromat PC...
  • Page 20 TOOL number IS important, since UP commands are used in conjunction with previously entered DOWN commands using the same TOOL number. NOTE:- DOWN and UP and DOWN and CTR commands for the same cut must be programmed with the same TOOL number. Micromat PC...
  • Page 21 The backup data can be re loaded into memory by pressing Shift and the L key. The memory of the Micromat will store 9,800 individual commands. This is exactly the same as the original Micromat systems and the number is retained for compatibility.
  • Page 22 Use 30,000 to 40,000 rpm for the 450 watt spindles. If a high pitched whine is heard then try reducing the cutter rpm, or increasing the cutting rate. For smaller cutters, e.g. 1 mm and under, use a higher spindle speed (55,000) and slower cutting rate. Micromat PC...
  • Page 23 Any measurement of routed parts should be conducted with great caution as changes in temperature can greatly change the size of a piece of laminate. Micromat PC...
  • Page 24 Positions 1 to 11 are programmed sequentially with DOWN commands at each point. Position 12 is then programmed with 3 commands, all in the same place:- DOWN, UP and END. Note that in this example points 6 and 8 are in the same position. Micromat PC...

  • Page 33 HOW TO ENTER, EDIT AND DRILL A PROGRAM In order to fully understand the operation of the Micromat, it is strongly advised that these instructions are followed, step by step, until the procedures become second nature to the operator. The basic controls will be dealt with first, and after becoming fully conversant with these the operator should progress to the section covering RPT, BRACKET, SIL, MOVE, and EXPAND commands.
  • Page 34 Reference coordinates will be set to Zero and a round target will appear on the TV picture. The system is ready for manual program entry. 2) Place your Micromat Drill Program Tutor No 1 on the bed of the machine with the arrow pointing towards the machine's HOME position.
  • Page 35 14) To finish, simply press the E key and an END command will be added to the program. The Micromat is now programmed to drill the 14 hole pattern which has just been entered. The program consists of 14 HOLE commands and one END command.

Try reprogramming some of the positions with different tool sizes and try using the CHECK function to view the result of running with different Tool number settings. PRACTICE MAKES PERFECT Micromat PC...
  • Page 40 The last Tool number to be run will stay YELLOW on the screen with a RED highlight END. The screen will also show the time taken and the number of holes drilled.

  • Page 49 The Tool number setting is irrelevant for REPEAT and BRACKET commands as they are automatically entered as Tool zero. When the program is in the RUN mode, any REPEAT and BRACKET commands will always be required whatever Tool number setting is used for RUN. Micromat PC...
  • Page 50 The commands entered are just the same as those entered manually and can be stepped through and edited just as normal commands. Micromat PC...
  • Page 51 PROGRAM MOVE AND EXPAND These functions are helpful to the programmer in that they allow patterns to be moved around the drilling bed of the Micromat and to be repositioned to make the best use of laminate blanks. The MOVE routine simply repositions a drilling or routing pattern, complete with any REPEAT or bracket commands.

  • Page 52: Program Move

    The command, and everything following it up to the END, will be moved, and the TV target will indicate the new position of that command. CAUTION The operator must ensure that the moved program will still fit within the limits of the drilling table. Micromat PC...
  • Page 53 If enough memory is available the Micromat will compute the new program and write it into memory in place of the old step and repeat program. The target will move to the first command after expansion.
