 Overhauls - numerical machines
In general, overhaul includes total disassembly of machine, exchange of bearings, seals, worn gear wheels, spindles, reinforcing of guideways with hardened steel plates (or their regrinding, if these are already on the machine), and their grouting with plastic material, complete machine geometry, replacement of covers, new electric installation and surface treatment. A necessary prerequisite is meeting the requirements of current legal regulations and technical standards, mainly in relation to the operational safety of the machine.
All the machines mentioned herein are upgraded substantially, in order to enhance their technical level and technological capacities to the current requirements of machining process.
Modern digital control systems are applied HEIDENHAIN (the iTNC 530 series) and SIEMENS (SIN 840D), with rich capacities of technological programming. They further facilitate e.g. interconnection of the machine with the company internal network for easy maintenance and distribution of technological programmes, or for servicing and diagnostics of the control system. The driving units and motors used are SIEMENS and HEIDENHAIN, depending on the control system used. New electric installation of the machines consists mainly of TELEMECANIQUE components. The drives of individual axes are executed through clearance-free transmissions of the timing belts and ball screws. Drive of table rotation is secured by planet gears resp. harmonic gears ALPHA resp. HARMONIC DRIVE. Table rotation is considered an accurate positioning axis (in optional angle), with the exception of machine WFQ80NCA-CNC, where this axis is fully interpolation (allows machining on cylindrical surface). Individual moving groups are usually hydraulically clamped.
Regardless the aforementioned parameters, all machines are available in a design with non-sliding spindle to 5000 rpm, or with motor spindle with parameters specified by customer.
Upon customer request, the machines can be equipped with automatic toolchanger (ATC), tool cooling kit (HCZ), oil-mist cooling, cooling through spindle axis (CHOV), workpiece cover, swarf conveyor or additional accessories, such as touch probes, milling heads, extra rotary tables, clamping angle plates, etc. The scope and design vary according to the type of the machine.
