Enerpac rotates oil cylinder and the combination of the oil cylinder that prop up can the clamp workpiece of on the safe side. Grow when treatment model when aluminium alloy spare parts, oil cylinder rotates when cutting tool is passed but quick get out of the way, after cutting tool is passed but fast restoration. Be in in the light of when set tigidity is propped up or cannot machining thin wall spare parts, hydraulic pressure is auxiliary propping up is first-rate choice. Rotate clamping apparatus and assist the combination that prop up to be able to make sure clamp workpiece is not out of shape. Hydraulic pressure built up fixture can realize multitask outfit clip, improve working productivity greatly. Reduce shutdown overhaul period is to improve productivity, make productivity utilization factor the biggest a when change main factor. The essence in process of spare parts treatment locates truly and hold clip however repeating precision also is the key that improves efficiency and quality. For example is flexible the generation of machining center is to reduce product total cycle time. On body of a stationary fixture, after using mechanical fixed position, clamp to machine again eliminate they, this is a measure of very beautiful time normally. To achieve high yield efficient, the fixed position of workpiece, prop up, of clamp and clamping apparatus fast and loose, and handling convenient, security is very important segment. To processing a greater work, and working procedure time interval is short, choose semi-automatic change or full automatic change clamping apparatus dispute to often have economic value. Hydraulic pressure fixed position and clamp are a very reliable and effective technology. Development of Chinese automobile manufacturing industry is at present swift and violent, the crucial component such as lid of the cylinder body that the automobile manufacturing industry previously uses rigid private plane generally to machine engine, crock, connecting rod, crankshaft, camshaft, bring about cycle of car engine remodel longer. To component as the car change and improvement requirement grow day and day, treatment facilities and craft also are sided with flexible the directional change that spend. Those who machine equipment is flexible concept and demand basically reflect the demand in fast to equipment sex and adaptability to go up, because this manufacturer must be sought flexible with the optimal combination between crop. Adopt which kinds of plan no matter, use high-powered hydraulic pressure clamping apparatus to appear particularly important, now, flexible the assorted application of the private plane, machine tool that can configure afresh and special machining center, make the treatment of engine spare parts becomes more and more flexible change, particular case depends on every output quota that processes a project. The main advantage of clamping apparatus of use hydraulic pressure is the many time that spends when can economic clamp and loose discharge workpiece. Traditional rigid clamping apparatus is in loosen and want to use spanner painfully to come back when clamp workpiece pigheaded nut and mobile pressing plate. However hydraulic pressure clamping apparatus needs to pass those who control oil path to connect the complete ordinal movement control that can realize clamping apparatus only. Concerned statistic data shows photograph of hydraulic pressure clamp compares mechanical clamp to save the time of 90%~95% , narrowed manufacturing cycle is periodic, increased crop to also be meant thereby reduced cost. The 2nd of system of hydraulic pressure clamping apparatus important characteristic is to be able to realize very tall fixed position precision.

The treatment quality consistency that ensured same way working procedure falls thereby, rise namely repeat precision, reason because this is out of shape the percent defective that cause will very little. Group by group the interchangeability of component also can reach good target. However almost rigid clamping apparatus cannot accomplish this. Be in in the light of when set tigidity is propped up or cannot machining thin wall spare parts, hydraulic pressure is auxiliary propping up is first-rate choice. It can is opposite in aleatoric position workpiece generation supports power, have the effect of auxiliary fixed position, the fixed position propping up that machines the surface to be not especially is more be not it to not be belonged to, strong settlement perplex us pass fixed position question. The 3rd advantage of hydraulic pressure clamping apparatus suits to machine a spare parts to put most namely compact the circumstance that accepts restriction with the space when using a hand to move clamp, this is the advantage with fluid advantaged control. This can realize many spare partses to install clip and treatment at the same time on body of a clamping apparatus. People can'ts help can asking, are which kind of clamping apparatus best? Compare rigid clamping apparatus, the cost of early days investment of hydraulic pressure clamping apparatus is higher, however from long-term in light of, it is cheap. See on the cost that expresses example is compared. Use hydraulic pressure clamping apparatus not only odd cost is reduced 19.
26 yuan, and the time that finish is shortened by two years to 18 months. CNC Milling
