The touchscreen sets speed, depth, and feed in seconds instead of the minutes required for belt changes or manual adjustment. The electromagnetic axis lock maintains the programmed position between holes. For series production of identical parts, repeatability is a concrete advantage compared to manually adjusted drills.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the maximum drilling diameter in steel and tapping size with the GB 55 NC Vario?\u003c\/summary\u003e\n\u003cp\u003eNominal drilling: Ø 55 mm in S235 steel. Tapping: up to M42. The capacity in AISI 304 stainless steel is reduced by 30–40%. For large diameter drilling (over Ø 35 mm), use the lowest available speed with automatic feed and abundant coolant.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat does the electromagnetic engagement of automatic feeds specifically allow?\u003c\/summary\u003e\n\u003cp\u003eWith electromagnetic engagement, the automatic feed is activated and deactivated via the touchscreen without touching physical mechanisms. For a series of identical holes: the depth is set once, the engagement is activated for the first hole, and the machine reaches the depth and retracts automatically. Typical cycle per hole: 3–5 seconds compared to 15–20 seconds for manual feed. For 100 identical holes, this saves 15–25 minutes.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs the drilling table inclinable?\u003c\/summary\u003e\n\u003cp\u003eYes – the table of the GB 55 NC Vario is hand-scraped cast iron and can be tilted from -45° to +45°, with motorized elevation via a button. Motorized elevation eliminates the need to unscrew and manually crank the toothed column – on heavy machines like this (over 500 kg), it's a concrete advantage in terms of time and effort.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre spare parts available?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 business days shipping.
