NOTICE FOR ARRANGING A GLASS BLOWING SHOP As the world’s biggest specialized company for glass working tools and glass working machines for processing of glass- and quartz tubes, we offer an extensive, wellrounded complete program. The forma on of our offer pale e is as follows: A) Complete arrangement for lamp glass blowers with burners, tools and working tables a) hand torches, bench burners – we recommend our modern noiseless bench burners „Zenit“ b) Glass cu ng knifes, Reamers from metal and graphite, Graphite plates c) Holder for pistons, grinds, threads etc. d) Roller, forceps, measuring tools B) Cu ng-off machines a er the crack/break-method, wet divide method and thermal shock method For the selec on of cu ng-off method, the material and size of the work piece is crucial. As universal useable cu ng-out saw for the cu ng-off of glass, quartz glass, ceramics and similar materials we especially recommend our cu ng-out saws, type 72 to 72/330. The cu ng quality can be op mised via appropriate diamond discs. For cu ng-off of all kinds of glass (but no quartz glass) we recommend our cu ng-off machine no 71/8 (thermal shock method) The principle offers the advantage, that the sheared edge stays absolutely transparent and thus, no joining places can be recognized at the further processing. A dirt accumula on via coolants is omi ed! C) Machines for the hot treatment Universal-Glass working lathes Glass working lathes, which are coordinated for the job area of the glass blowing shop should not missed in a modern workshop. Glass working lathes enable the treatment of big tube dimensions and the produc on of complicated glass repairs. We built the standard lathes with spindle bores of 80 mm up to 750 mm. Small lathes serve for the produc on of precise instruments and for the mechaniza on of working cycles. We built these table models in different designs with spindle bores of 16 – 80 mm. A partly or fully automa on of the glass working lathes is possible. Tell us your problems, we are gladly available with our long experience. D) Quality assurance Hot trea ng implements made from glass show tensions a er cooling. For releasing the tension we offer electrical heated cooling ovens as muffle furnace and top hat furnace in many sizes and in two nature regions up to max. 1280°C (thus, its even applicable for quartz glass). For the op cal tes ng of the tension we build glass tension testers in different sizes and execu ons, from small hand-operated testers to a very popular table model up to a big footed cabinet. (The hand-operated tester is even applicable for tes ng of already installed glass equipment). E) Grinding shop - arrangements a) We deliver spindle grinding machines in special execu ons for the receiving of grinding tools for grinding of standard ground joints, spherical ground joints and stop cock barrels. b) Horizontal-grinding machines (facing grinding machine) for the tube end-treatment. These machines are working with cast discs and need addi on of abrasive (Silizium- Carbid). c) Belt grinding machine, which can be equipped with corundum grinding belts and cork polishing belts, for the tube end treatment, for facet, etc. d) Glass drills for the use of conic diamond rub tolls (grinding tools) and diamond hollow drill. For smaller drilling capaci es up to approx. 30 mm and the use of conic diamond grinding tools up to approx. NS 60, we recommend model no. 561. For bigger drilling capaci es up to 100 mm diameter and for the use of grinding tools up to approx. NS 60, we recommend the column drill model 564. With exposi ons men oned before, we can only try to point out some considera ons with the arrangement of a glass blowing shop. To advise you op mally, the answering of the following ques ons is very helpful: 1. How many glass blower work places will be arranged? 2. What will be produced? 3. Which max. gas tube dimensions should be treated now in future? 4. Which kind of gas is available? 5. Should quartz glass be treated, too? Manufacturing of serial ar cles We build manual operated and PLC-controlled forming machines, especially for standard ground joints, spherical ground joints, stop cock barrels, threads,flanges etc. We gladly cooperate the size and execu on of these machines to the provided opera ve range. - We refer to the machine series type 48 and type 54 Half automa c, micro processor controlled blowing machines for graduated flask, round piston and similar glass vessel as well as special lathes with addi onal middle chuck for adding side parts on both sides – e.g. side arms on stop cock barrels – complete the program for the produc on of laboratory glass. 25
