Sveza Flex is 100% birch plywood with a special panel structure for use in column/tunnel formwork. Engineering Toolbox Here is a great article: What Every CNCer Ought to Know About Tool Deflection. Thank you, Veit. gwizard is recommending a 100ipm feedrate at 10k rpm when I enter in that info. script.src = "https://js.convertflow.co/production/websites/581.js"; Cutting through the wood in 2/3 or three passes is fine! It refers to the chipping characteristics of the plastic. This reduces their likelihood of splintering, and it also makes the cutters cheaper. For plywood I use usually 420-480 mm/s (7-8mm/s), for harder wood 360 (6mm/s) feed rate. The CNC cutting parameters that I have used are: **For plywood 12 mm feed rate 300 mm/min - number of passes 7 **For plywood 10 mm feed rate 250 mm/min - number of passes 6 BIT used Straight end mill milling cutter flutes (tungsten steel) 1/8" cutting diameter and 1/8" shank diameter. 8mm 100% 1000 cut rate 6 passes 0.5 depth changes (fire likely) 3mm 100% 700 cut rate 3 passes. document.write(''); Feed refers to the linear rate in inches/minute or millimeters/minute that the cutting tool moves through a material. 1” 60 degree V cutter. Geometry causes rubbing when we feed cutters too slowly. You need to feed at a rate that provides the correct chip load. { So our feed rate is 260 inches per minute, producing a chip load of 0.0072 with a ramp-down or plunge rate of 130 inches per minute. This destroys a tool suddenly and is more commonly what beginners see. Cutting deep tight slots can be problematic for this type of cutter sometimes. Use and adjust the feed rate according to its appropriate pass. Depending on the size of your bit, the chipload for plywood is between 0.005 inches 0.01 inches per tooth. 1. Blog Laser Comparison – Cutting Speed and Rate of Feed. Feed Rate = RPM x number of flutes x chip load . So for a Version 1 machine, this will be set to 15 mm/sec and for a version 2 machine, you will set this to 25 mm/sec. This is why so much router work prefers Carbide tooling even though wood is relatively soft. And all of these assume that the setup of fences, guide blocks and holddowns are correctly in place. Feed Rate: 10-11m/min Recommended parameter to cut 1-0.7cm MDF: 18000rpm Feed Rate: 7-8m/min For other model, please leave a common, I will respond you as soon as possible. Blog Laser Comparison – Cutting Speed and Rate of Feed. Chip Load per leading edge. With small desktop machines, its good to limit the depth of cut based on your machines capabilities. Use sharp cutters.  If you can run your fingernail over the edge without shaving off a bit of fingernail, your cutter is probably dull. 2. | Contact.

Dnes jsou cílem k trestání Maďarsko a Polsko, zítra může dojít na nás

Published

on

„Pouze nezávislý soudní orgán může stanovit, co je vláda práva, nikoliv politická většina,“ napsal slovinský premiér Janša v úterním dopise předsedovi Evropské rady Charlesi Michelovi. Podpořil tak Polsko a Maďarsko a objevilo se tak třetí veto. Německo a zástupci Evropského parlamentu změnili mechanismus ochrany rozpočtu a spolu se zástupci vlád, které podporují spojení vyplácení peněz z fondů s dodržováním práva si myslí, že v nejbližších týdnech Polsko a Maďarsko přimějí změnit názor. Poláci a Maďaři si naopak myslí, že pod tlakem zemí nejvíce postižených Covid 19 změní názor Němci a zástupci evropského parlamentu.

Mechanismus veta je v Unii běžný. Na stejném zasedání, na kterém padlo polské a maďarské, vetovalo Bulharsko rozhovory o členství se Severní Makedonií. Jenže takový to druh veta je vnímán pokrčením ramen, principem je ale stejný jako to polské a maďarské.

Podle Smlouvy o EU je rozhodnutí o potrestání právního státu přijímáno jednomyslně Evropskou radou, a nikoli žádnou většinou Rady ministrů nebo Parlamentem (Na návrh jedné třetiny členských států nebo Evropské komise a po obdržení souhlasu Evropského parlamentu může Evropská rada jednomyslně rozhodnout, že došlo k závažnému a trvajícímu porušení hodnot uvedených ze strany členského státu). Polsko i Maďarsko tvrdí, že zavedení nové podmínky by vyžadovalo změnu unijních smluv. Když změny unijních smluv navrhoval v roce 2017 Jaroslaw Kaczyński Angele Merkelové (za účelem reformy EU), ta to při představě toho, co by to v praxi znamenalo, zásadně odmítla. Od té doby se s Jaroslawem Kaczyńskim oficiálně nesetkala. Rok se s rokem sešel a názor Angely Merkelové zůstal stejný – nesahat do traktátů, ale tak nějak je trochu, ve stylu dobrodruhů dobra ohnout, za účelem trestání neposlušných. Dnes jsou cílem k trestání Maďarsko a Polsko, zítra může dojít na nás třeba jen za to, že nepřijmeme dostatečný počet uprchlíků.

Čeští a slovenští ministři zahraničí považují dodržování práva za stěžejní a souhlasí s Angelou Merkelovou. Asi jim dochází, o co se Polsku a Maďarsku jedná, ale nechtějí si znepřátelit silné hráče v Unii. Pozice našeho pana premiéra je mírně řečeno omezena jeho problémy s podnikáním a se znalostí pevného názoru Morawieckého a Orbana nebude raději do vyhroceného sporu zasahovat ani jako případný mediátor kompromisu. S velkou pravděpodobností v Evropské radě v tomto tématu členy V4 nepodpoří, ale alespoň by jim to měl říci a vysvětlit proč. Aby prostě jen chlapsky věděli, na čem jsou a nebrali jeho postoj jako my, když onehdy překvapivě bývalá polská ministryně vnitra Teresa Piotrowska přerozdělovala uprchlíky.

Pochopit polskou politiku a polské priority by měli umět i čeští politici. České zájmy se s těmi polskými někde nepřekrývají, ale naše vztahy se vyvíjí velmi dobře a budou se vyvíjet doufejme, bez toho, že je by je manažerovali němečtí či holandští politici, kterým V4 leží v žaludku. Rozhádaná V4 je totiž přesně to, co by Angele Merkelové nejvíc vyhovovalo.

Morawiecki: Hřbitovy budou na Dušičky uzavřeny

Published

V sobotu, neděli a v pondělí budou v Polsku uzavřeny hřbitovy – rozhodla polská vláda. Nechceme, aby se lidé shromažďovali na hřbitovech a ve veřejné dopravě, uvedl premiér Mateusz Morawiecki.

„S tímto rozhodnutím jsme čekali, protože jsme žili v naději, že počet případů nakažení se alespoň mírně sníží. Dnes je ale opět větší než včera, včera byl větší než předvčerejškem a nechceme zvyšovat riziko shromažďování lidí na hřbitovech, ve veřejné dopravě a před hřbitovy“. vysvětlil Morawiecki.

Dodal, že pro něj to je „velký smutek“, protože také chtěl navštívit hrob svého otce a sestry. Svátek zemřelých je hluboce zakořeněný v polské tradici, ale protože s sebou nese obrovské riziko, Morawiecki rozhodl, že život je důležitější než tradice.

Poslankyně opozice atakovaly předsedu PiS

Ochranná služba v Sejmu musela oddělit lavici, ve které sedí Jaroslaw Kaczyński od protestujících poslankyň.

„Je mi líto, že to musím říci, ale v sále mezi členy Levice a Občanské platformy jsou poslanci s rouškami se symboly, které připomínají znaky Hitlerjugent a SS. Chápu však, že totální opozice odkazuje na totalitní vzorce.“ řekl na začátku zasedání Sejmu místopředseda Sejmu Ryszard Terlecki.

Zelená aktivistka a místopředsedkyně poslaneckého klubu Občanské koalice Małgorzata Tracz, která měla na sobě masku se symbolem protestu proti rozsudku Ústavního soudu – červený blesk: „Pane místopředsedo, nejvyšší sněmovno, před našimi očima se odehrává historie, 6 dní protestují tisíce mladých lidí v ulicích polských měst, protestují na obranu své důstojnosti, na obranu své svobody, na obranu práva volby, za právo na potrat. Toto je válka a tuto válku prohrajete. A kdo je za tuto válku zodpovědný? Pane ministře Kaczyński, to je vaše odpovědnost.“
